Summary:

Pound for pound, Mutant Mass is the best weight gainer on the market. Highly recommended for anyone looking to pile on slabs of muscle mass in a short period of time.

I had just finished my first marathon and after four months of endless cardio, vaseline and one very sore ballbag, I was left looking a little on the slim side.

I wanted to gain muscle mass – and fast.

It’s not that I didn’t mind looking a little slimmer, I just wanted to build some serious, intimidating bulk.

Let’s face it, Mo Farrah might be able to run a mile in 3.30 minutes, but tasked with ordering a round of WKDs at Wafou Norwich on a busy Wednesday night?

No chance!

While my gym programme was shaping up nicely (I was doing Stronglifts 5×5, a no-nonsense full-body routine which focuses on squat, deadlift, bench, rows and overhead press), it became apparent that I needed to turbocharge my diet for the sizeable results I was after.

It was at this point that a friend recommended I try Mutant Mass.

In his professional opinion, I would “hit 17 stone on this bad boy – instantly”.

I was sold.

Product overview and ingredients

True to its name, Mutant Mass is an absolute behemoth amongst weight gaining supplements.

Mutant MassIt packs a multitude of impressive ingredients, but perhaps the most eye-popping USP is the sheer amount of calories it contains.

1,060 kcal per serving, to be precise.

Let’s put that in perspective…

That’s about the same number of calories as a typical Sunday roast – in one shake.

Completely obscene!

When it comes to the rest of its goodies, per serving we’re looking at a nice ratio of carbs to protein (182g clean carbs, 52g protein), a decent blend of amino acids (great for aiding recovery) and some high-fat MCTs derived from coconut oil.

Per 260g serving, the nutritional profile shapes up as follows:

Calories 1060kcal
Protein 52g
Carbs (of which sugar) 182g (38g)
Fat (of which saturates) 14g (8g)
Fibre 8g
Sodium 580mg

The protein blend is mostly derived from whey protein concentrate but also includes milk protein concentrate, milk protein isolate, micellar casein, calcium caseinate, whey protein isolate, whey protein hydrolysate, modified milk ingredients and egg albumen.

The recommended number of scoops is four per serving.

Yes, four!

By the very fact I had to shovel this colossal of mound of powder into two separate shakers, I knew this experience was going to go one of two ways:

One way was good, the other… would be fucking horrible.

Taste and texture

I used a blender to mix Mutant Mass with milk, and I was pleased to find that, on drinking it, lumps were minimal.

Good start.

However, due to the absolute tidal wave of calories, it was still a struggle to get down.

I tried shaking it once, without a blender, but never again.

Getting the thing into a drinkable state required a titanic effort and considerable wrist strength – think power wank.

power wank gif

Taste-wise, I had no complaints.

I opted for the ‘Cookies and Cream’ flavour and, quite frankly, it tasted delicious.

Mind you, I was a student at the time, so bear in mind my palette had been corrupted by a strict diet of burnt toast, kebabs and industrial strength cider.

Other available flavours range from ‘Strawberry Banana Creme’ and ‘Triple Chocolate’ to ‘Vanilla Ice Cream’ and ‘Peanut Butter Chocolate’.

Effectiveness

The 6.8kg bag of Mutant Mass lasted me just over three weeks, and in that time I achieved some pretty impressive size and strength gains.

Alongside a high calorie diet, four one hour workouts per week, and minimal cardio, I put on about half a stone in weight.

And the good thing was that most of this bulk was clearly muscle mass.

Obviously, with a weight gainer of this magnitude, it’s never going to be 100% muscle.

Inevitably, I grew a little bit of a gut – but nothing some increased cardio wouldn’t fix.

Perhaps more impressive, however, were the strength gains.

Let’s take every gym rat’s favourite exercise – the bench press.

Prior to taking Mutant Mass, I had plateaued at around 85kg for 5×5.

During my three week stint with this mass gainer, I was able to increase the weight I was benching on 5×5 from 85kg to 95kg.

What’s more, I managed to increase the weight I was pushing on all my other compound exercises quite considerably, with similar gains on the squat, deadlift and press.

Mass moves mass, QED.

Side effects

No Mutant Mass review would be complete without mention of one inconvenient side effect…

WARNING: As well as building mutant size, this product will give you some serious methane issues.

We’re talking toxic guff gas here.

I cleared offices, supermarket aisles, tube carriages, and, on one occasion, around 25 people from the dancefloor of my student union.

And if that wasn’t enough, every shit was like giving birth.

This stuff made me feel continually bloated – it was like digesting cement.

DO NOT drink Mutant Mass before a night out, otherwise it’ll be turtle bellies all round.

Value for money

Usually retailing at around £68 / $75 for a 6.8kg bag on Amazon, value-for-money is pretty damn good if you ask me.

Obviously it’s not cheap, but for what you get, it is, in my opinion, one of the better value weight gainers on the market.

It’s certainly a safer bet than some of the bargain basement brands out there (Myprotein Hard Gainer Extreme comes to mind) which are saturated with sugar and fillers rather than high-quality MCTs and complex carbs (waxy maize starch etc).

Mutant Mass is certainly the best mass gainer I’ve ever reviewed and Will Kennard reaches the same verdict in our must-read Mass Gainer Showdown.

Verdict

Pound for pound, Mutant Mass is the best weight gainer on the market, and is highly recommended for anyone looking to pile on slabs of muscle in a short period of time.

Pros Cons
Builds lean muscle mass Mutant gas
Tastes delicious Tough to digest
Boosts strength gains
Great value for money
Aids recovery

  1. I used to pop ‘homemade’ shakes with peanut butter, eggs and oats in and I thought that was difficult to drink, but after trying to down Mutant Mass it felt like I was using Susan Boyle’s queef as air supply for the next 2 hours.

    1. Thanks for that visual image, sir.

      However I’m not sure your simile works.

      Mutant Mass tastes very sweet, and I believe Boyle’s vulvic aroma would be a little on the sour side.

      I could be wrong though.

  2. Hi Henry – Some discrepancies.

    Your article says you bench 95kg but in your photo you look about 20 stone.

    Is this real life?

    1. You are right to question this discrepancy.

      In this particular picture my head has been photoshopped onto the body of Jay Cutler.

      I stare at it every day for 15 minutes for motivation.

  3. What exactly is a clean carb?

    I have not come across this term before in scientific literature.

    Also it would be helpful if you had discussed the sources of protein, since as we all know (or should know) they are certainly not equivalent in their absorption characteristics.

    Personally I wouldn’t touch this stuff unless I spent 3 months in a detention camp, emancipated on a diet of dry oats and tap water.

    The carbohydrate content is too high for anything but a desperate dirty bulk cycle.

    But for hard gainers or noobies, it might be worth the dough.

    1. Thanks for your comment, Oscar.

      Out of interest, are you really a professor, or is this some kind of pseudonym?

      Anyway, to answer some of your points:

      The ‘clean carbs’ to which I refer include the waxy barley starch and waxy maize, which are absorbed by your body very quickly – certainly faster than most carb sources. They also increase the speed of muscle glycogen refueling to a greater degree than other carbohydrates.

      Secondly, you are right to point out that all protein sources are certainly not equivalent in their absorption characteristics. An excellent point.

      For your reference, the protein sources in Mutant Mass include: whey protein isolate, whey protein hydrolysate, three different whey protein concentrates, micellar casein, milk protein concentrate, calcium caseinate, egg white albumin protein, and milk protein isolate.

      Also, you are indeed right in your comment that any choice in supplements is a personal one, as people’s goals differ considerably. I ordered Mutant Mass precisely for the ‘desperate bulk cycle’ which you refer to.

      Hope this helps.

  4. Great review, I think it can be found a bit cheaper on the web now (<£52) but I'm probably not going to do another bulking cycle till next year.

    Perhaps for an article you could explore options for making your own cleaner mass gainer shakes?

    1. Hi Jizzmeister, thanks for your comment.

      When I wrote the review Monster Supplements was the cheapest out there.

      I’ve ordered from them a few times and the service has always been stellar, so was inclined to recommend them.

      Love the idea about a homemade mass gainer shake article!

      I mean, literally anything can be liquidised with a powerful enough blender – Sunday Roasts, slabs of cheese, chicken and chips.

      Certainly an entertaining/completely pointless idea! Very Gym-Talk!

      By the way, have you seen our homemade protein shake article?

  5. Hi, I’m new to all this, I’m thinking of getting Mutant Mass as well as the Cre-X12.

    I am just unsure how to fit this into a proper diet as the diet is my weakness, I have no idea meal wise what to be eating.

    Any info from you guys would be great.

    Thanks

    1. Hi Rikdogg, thanks for the comment.

      I guess it all depends what you’re looking to achieve, but judging by the fact you’re considering buying Mutant Mass I’d say you’re looking to build muscle size and bulk up in general?

      I can send you a fairly basic but effective meal planning system if you’d like?

      1. Hi Greg, yes I’m trying to bulk up and put some muscle on.

        It would be great if you could send a meal plan.

        Thanks

        1. Hi Rikdogg

          As I’m patently not a nutritionist I’m not gonna try and design something myself.

          http://www.bodybuilding.com/fun/shortcut-to-size-nutrition.html

          This is a meal plan designed by Dr Jim Stoppani, designed to pack on 6-12kg of lean muscle (if you follow his workout as well).

          This is quite an extreme diet approach, you will definitely gain weight but it might be a bit too much/expensive – I don’t know your situation so it’s hard to comment.

          Like with most things, it’s all about what you feel is right for you, so perhaps use this diet as a guide.

          Following anything exactly is a hassle, especially when you’ve never even heard of some of the ingredients.

          If that fails then Google ‘GOMAD diet’ and see if you fancy taking that on!

  6. I have been using Mutant Mass and I do like it.

    I’ve seen a bit of a difference, but I have been gaining also where I do not want too – belly.

    I have been working on my abs and was doing good.

    Now I’m starting to see my abs less.

    Should I increase cardio?

    1. Hi Don.

      If you’re taking a weight gainer like Mutant Mass, you’re going to have a tough time obtaining that ripped torso you’re after.

      It’s calorie count is going to stand in the way of ridding that layer of fat covering your abdomen.

      You firstly need to adjust your diet by cutting down on fats, sugar and refined carbs such as white bread.

      Also, you need to step up your cardio, as this will speed up the process. Try doing more high-intensity compound lifts (squats, deadlifts) as in addition to burning more calories these movements will also work your core.

      Killing two birds with one stone!

      Hope that helps, let me know if you have any more questions!

      Henry

  7. Hello sir, I would like to ask for some advice.

    I am only 18, and kinda skinny, really skinny.

    I want to ask which among the supplements should I use.

    Creatine powder or Mass?

    1. Hi Johnny.

      I wouldn’t worry too much about supplements at your level.

      It’s more important to focus on a workout schedule built around high intensity compound lifts (deadlifts, squats) and complement this with a high protein diet.

      For example, a workout programme such as Jim Stoppani’s Shortcut to Size would be a good place to start.

      Both creatine and a mass gainer will help with these goals, but it is more important to get the basics right first.

      Let me know you get on and if you have any more questions.

      Henry

  8. Hi, I just want to know the proper serving for Mutant Mass, preferably the daily intake.

    Your help is much appreciated.

    1. Hi Jake.

      Thanks for your comment.

      The recommended amount of scoops per serving is four – but this is quite difficult to get down if you’re just starting out.

      Two or three scoops is going to be just as effective.

      I took two Mutant Mass shakes per day in addition to three/four meals, and the results after a month were very impressive.

      Hope that helps – let me know how you get on!

      Henry

      1. Yes I will inform you.

        After my first time of taking it I got tummy disturbances, I don’t know if it’s normal but it made tummy sick…

  9. Alright guys, I went through 3 x 15 lb bags of this, so I do have the experience with the product to comment properly.

    Firstly, I’ve tried all their flavours, and when it comes time to down another shake, I literally sit there for 15-20 minutes thinking about downing it, because it’s so nasty, and plus I know the consequences I will experience shortly after.

    In short, if you don’t like the anus burning sensation, don’t use this product.

    After every use, my ass would burn like no tomorrow, where I would literally have to put vaseline.

    I thought after a week or two, my body should get use to it and it would stop, but nope, it didn’t.

    I had a clean diet while on this, and have taken the shake after eating solid meals.

    There is also a gas mask on the bag for a reason, I don’t think I need to detail further.

    So while you can make good gains off of this providing you have your diet in check, is it really worth the after effects?

    After 3 bags of use, I can honestly say I will never touch Mutant Mass again.

    To list top 4 gainers you could try are (not in any specific order): Pro Gainer (Optimum), Quick Mass (All Max), Carnivore, Big Time (Precision) Carnivore Mass (MuscleMeds).

    Some of these gainers contain 5g of creatine a serving, so check the profile before deciding.

    Stay away from Mutant Mass if you care about your ass.

    1. Hi Alan, thanks for your vivid comment.

      I certainly agree that Mutant Mass can wreak absolute havoc on your bowels!

      I haven’t tried any of the other mass gainers that you mention, will definitely look into reviewing some on this site.

      How easy are they to digest?

  10. Hi!

    Is it advisable to take Mutant Mass if I want to gain muscle mass in different parts of my body (chest, back, shoulders, arms and legs) and building abdominal muscles at the same time?

    Because I’m afraid that it will make my core section gain fat and give me a hard time in achieving a six pack.

    If that happens, is there a way to prevent it when I start taking Mutant Mass?

    Thanks!

    1. Vain, if you’re putting the time and effort in at the gym – and hitting your compounds hard – then Mutant Mass will definitely help you pack on some muscle mass.

      However, with the colossal calorie load, you’re going to have a tough time maintaining that six pack.

      For a “cleaner” bulk, check out the Total Mass Matrix that Greg mentions below.

  11. Hi Henry, I’m 25 and I’ve been working out for about 2 months and I see no results whatsoever.

    I weight only 121 pounds – will taking Mutant Mass will help me fast?

    1. Hi Zlatan, if you’re not seeing any results yet, I would 100% advise against taking any supplements.

      You need to get your training and nutrition up to scratch first, then you can experiment with supplements when you have that down.

      Have a look at some of Charlie’s articles here on GymTalk, they should point you in the right direction.

      For starters: http://www.gym-talk.com/7-rookie-mistakes-slow-gains.

      Good luck and let us know how you get on!

  12. Hi, Henry.

    Is this clean bulking technically? Or is it pretty dirty?

    1. Definitely more of a dirty bulk, if you want something ‘cleaner’ check this out:

      http://www.gym-talk.com/total-mass-matrix-review/

  13. I’m talking only 2 scoops after workout for the last 2 months now and have made nice muscle gains.

    I put on a stone in that space of time.

    My body fat went down as well so more ripped now and vascular.

    The taste is a bit on the sweet side but it gets to the stage where I want a shake all the time.

    Mixes great with only 2 scoops.

    I workout 4 times a week and eat great as well with this but I’d recommend mutant to anyone.

    It’s not just a dirty bulk product either, it’s my everyday protein and I won’t be changing.

    The 6.8 bag lasts for a good amount of time as well.

    1. Glad to hear your making some nice gains, keep on lifting buddy 🙂

  14. Hi Henry, good day!

    Would you kindly give me advise on whether Mutant Mass is beneficial to me as I am a skinny guy (50kgs, 5’5″).

    Actually, I am just on my 1st week on hitting the gym.

    Thanks, man!

    1. Yes, Mutant Mass will help you bulk up.

      Use it alongside a workout regime like this one, which is built around high intensity compound lifts, and a sensible high protein diet.

      This will give you the best results, good luck!

  15. I’ve been using Mutant Mass for about 6 months now and can only say good things, I can imagine having stomach problems drinking a whole serving but I only use half servings in the morning and post workout and am fine!

    Whole servings are unnecessary as you’re body will not absorb it all.

    Best gainer on the market for anybody who I wants to increase calorie intake to boost size and strength.

    1. Definitely agree with you mate, easily one of the best gainers on the market!

  16. If I decide to only take 2 scoops after each workout, would I cut the ounces of water in half as well or still use the 32 ounces?

    Sorry, probably a stupid question but I’m a little curious.

    1. No, just use the same amount of water, this won’t affect the nutritional value.

  17. Hello.

    I’ve just finished using a tub of Hydrobuilder Platinum and I’ve seen chest and ab shape outline not rock solid yet, but I’m skinny: 1.8m tall but 73kg.

    So I’ve been told that this can help.

    If I am correct, does this product help you gain muscle on the parts of your body you train?

    Like the parts you train e.g. chest – it opens windows for the nutrients from Mutant Mass to enter?

    Also, I’ve read reviews here that you might end up with a belly.

    I have a big concern since I just slimmed that area by 50% as I had a significant belly before and now only when I tense I see the 6 pack abs.

    Considering I still have a little belly… ish.. is it recommended I use this?

    And will doing more cardio while taking this allow a minimisation of belly being fat being formed?

    I’m looking to have a more bigger muscle chest to wear a nice V neck shirt.

    I’m not doing free weights. I’m using the machines at this point and that’s yeah working ish..

    Also what flavour is best? Taste wise?

    Any I should stay away from since I’m not good at consuming bad tasting drinks?

    1. Firstly, no supplement will help you train specific muscle groups, that’s utter garbage.

      If you want to slim down and lose the belly while putting on some lean muscle, Mutant Mass is not the ideal choice of supplement.

      It has far too many calories.

      You want something a lot “cleaner”.

      If I were you, I’d bin the resistance machines, start hitting the compound exercises (which will help you build muscle and burn calories), eat clean, and if you really want to supplement your diet, go with some cheap and cheerful creatine and whey protein.

      Hope that helps.

  18. How can I gain strength for this product?

    I’m taking 2 scoops after workout since day one of 3 months.

    Honestly it is a good product though.

    It added 30lbs in my routine like the bench press.. hehe

    1. No (legal) supplement is a magic bullet that will increase your strength as if by magic.

      First, you NEED to put in hours of hard work with the big compound lifts – only when you have this down will supplements give you a helping hand.

  19. I’m 5″9 and weigh 115 pounds (180cm/53kg) and have extreme trouble gaining weight.

    I find it hard to shove my face with so much food (I do eat very large amounts though) and have tried a few types of gainers before and have lost weight!

    I have purchased a 2.2kg bag of this stuff to try it out during the next week 2-weeks… so wish me luck!

    1. Mutant Mass should definitely be able to help with your goals.

      Good luck, and let me know how you get on!

  20. Henry, you are one funny fucker!!!

    And I mean that with much respect and sincerity 😉

    I haven’t laughed as much reading a review as I did when I read this one of yours, gold mate! 🙂

    Looking for a step up in weight gain so will give Mutant Mass a go.

    I’m a competitive powerlifter, or should I say a returning competitive PL and need 4kgs to reach the upper limit of my weight class (84kg).

    We’ll see how it goes.

    Appreciate the review… even though my missus probably won’t enjoy the increased methane output, ah well… price to pay huh?

    1. Hi Rabs, glad you enjoyed it 🙂

      Check out some of our other reviews for more gratuitous swearing and unnecessary knob jokes.

  21. Henry,

    I’ve never been able to put on any size, I’m a ‘hardgainer’, and after all my hardwork all I gain is ‘harder’ muscles, this isn’t my goal.

    I want to bulk up as quickly as possible, without so much of a belly.

    What do you suggest?

    Is Mutant Mass the way forward?

    In the past I’ve ate serious amounts of foods, of course the right foods, not just anything.

    I have no idea what to try?

    It’s all seeming pointless.

    I’m 17, I weigh about 10 stone 5, and I’m 6 Foot.

    Also would it be possible for me to e-mail you regularly?

    Any help is much appreciated, thanks.

    1. Hi Tom.

      First off, don’t get disheartened.

      You’re only 17 and just at the beginning of your journey into the IRON.

      As I’ve said numerous times on this thread, do not go looking for answers in supplements.

      Get your workouts in shape first.

      Start hitting the big compound lifts (squat, deadlift, bench, pull ups, bent over row) a few times a week – I recommend a 5×5 full body routine – and stick to a sensible high protein diet.

      The results will come, I promise.

      And, yes, feel free to email me for further advice 🙂

  22. I have been using Mutant Mass for about 2 months and I think and I have seen results.

    But not how I really want to gain weight and muscle strength – what would be my best route?

    While reading these comments I saw that you should take 2 scoops in the morning and 2 scoops post workout, do you agree with that statement?

    1. Hi Tim, glad to hear you are seeing some results mate.

      Before we talk about ramping it up to the next level, can I just ask you what routine you are doing in the gym?

      I have a sneaky suspicion that like most guys on here this is where your real problems lie.

  23. Hi, I’m just starting this Mutant Mass and I’m a bit skinny, but the belly part is quite big for my build.

    What do you suggest?

    I would like to gain mass but not increase the size of my abs – trying to trim it now.

    I’m just taking 1 scoop every night before going to bed as I am afraid because I’m lactose intolerant.

    When will I expect to see a difference in my body with this kind of serving?

    Do you have any idea?

    For faster results shall I increase the serving?

    1. Hi Ron.

      As I have said time and time again on this comments thread, FORGET about supplements and servings and scoops and all that bollocks.

      Make sure you are doing the right stuff IN they gym first.

      What routine are you currently following?

  24. My first month in gym just expired today, I’ll be starting again next week Monday.

    Gonna enroll again.

    I’ll be buying Mutant Mass here in the Philippines and post some reviews after finishing one pack of Mutant Mass.

    May I?

    Does Mutant Mass really give you mutant gas? Haha.

    1. Good luck Ivan, be sure to let us know how you get on!

      And as for the gas, let’s just say the Mrs was relieved when I finally finished the pack.

      Smoked her out a number of times!

  25. Hi Henry, I trained in the past for 5 years, and kinda got lazy cause of school and my jobs, now I have more free time and I want to go back in the gym.

    So, my question is, is it OK to take the product on the first day in the gym?

    I hear different opinions and I am not entirely sure, thanks.

    1. Hi Andrew, that’s absolutely fine.

      The key thing to remember is to be consistent with your training and diet.

      As an old gym buddy of mine used to constantly preach, you’ll get a bigger payoff for doing everything ‘right’ for a month than doing things haphazardly for 3 months.

      Good luck and let us know how you get on!

  26. Good day sir.

    What is the best time to drink Mutant Mass?

    And what’s the difference between Mutant Mass and Mutant Whey?

    Thanks sir.

    1. Hi Kevin, there is no ‘best time’ to take Mutant Mass.

      Take it whenever you want between meals to help you meet you meet your daily macros.

      Just make sure you are not using Mutant Mass as a meal replacement as the goal is to add calories to your diet!

      As for Mutant Whey, I’m not familiar with the product, but I assume it’s just a whey protein supplement, whereas Mutant Mass is a weight gainer.

      Hope that helps, let me know if you have any more questions.

  27. Hi there.

    I’m 18, I need advice on bulking up.

    I’m quite tall (6ft1,185cm) and only weigh 70kg.

    I would like to get to at least 85kg.

    I work out 3 times a week with dead lifts, squats, bench presses and don’t see any results.

    I think I have a really fast metabolism and am an ectomorph(hardgainer).

    I try to eat everything in front of me and my body just doesn’t seem to store and fat anywhere leaving me skinny.

    Do you think Mutant Mass will help me gain weight?

    1. Hi.

      First off, it sounds like you have the exercises nailed down, which is great.

      If you’re not already on the case, I would recommended a strength protocol such as 5×5 and full-body routines.

      Read more here:

      http://www.gym-talk.com/10-old-school-commandments-for-building-muscle/

      Now you just need to EAT BIG.

      Introducing a weight gainer like Mutant Mass will definitely push up your calorie intake and help you bulk up.

      Good luck, and let us know how you get on!

  28. Hi sir Henry.

    I just bought this Mutant Mass, is it OK if I take 1 scoop in the morning, 1 scoop at lunch, 1 scoop after working out, and the last scoop before going to bed?

    Is it OK sir?

    1. Hi Marty

      The goal with any weight gainer supplement such as Mutant Mass is to add calories/protein to your existing diet.

      So rather than using Mutant Mass as meal replacement or an addition to a regular meal, use it between meals to ensure you are massively increasing your daily calorie intake.

      You will perhaps find this difficult at first and experience a lot of bloating and fullness, especially if you are not used to consuming this many calories, so dial down the serving at first and then gradually increase it.

      Hope that helps, let me know if you have any more questions, and good luck with your training!

  29. Good Day Mr Henry,

    I would just like to ask if it’s good to change the supplement?

    Before, I used Serious Mass, but for now I will use this Mutant Mass.

    Is it better to use this before and after workout?

    I’m only 20 yrs old, 5’11, 63kg.

    I do not necessarily need to be bulky, just slim and fit, buff a little bit.

    In short, like a model.

    Can you give me tips how to get that?

    Thanks.

    1. Hi Lawrence.

      Firstly, if your goal is to achieve that slim and toned cover model look, I would steer clear of weight gainers such as Mutant Mass and Serious Mass.

      They will help you add a lot muscle mass (provided you are training and eating well) but they’ll also add a lot of unwanted mass too, which will prevent those six pack abs from standing out.

      If you want to get lean, I would, instead, pick up a regular whey protein supplement, maybe with a few added ingredients to help support weight loss.

      Use this as a snack between regular meals or a as a quick protein fix post-workout.

      Let me know if you have any more questions – and good luck with your goals!

  30. I have not used this supplement I plan to buy more, so I can draw my own opinions, maybe I can get to be the same size as Rich Piana

    1. I think you’ll need more than Mutant Mass…

  31. Hi Henry.

    Is this product better to take with full fat milk, semi-skimmed milk or water?

    And also how many scoops would you recommend for me to take?

    I’m 6ft and weigh around 82.5kg and go to gym around 5 times a week?

    Thanks

    1. Hi Owen, thanks for commenting.

      I personally used semi-skimmed milk.

      Full cream milk will certainly bump up the calories but this will be much more of a dirty bulk i.e. you’ll get fat if you’re not burning enough calories.

      As for the scoops, I would start by taking 2 and see how you get on.

      The full dosage (4 scoops per serving) will likely leave you feeling bloated and uncomfortable at first.

  32. Hey Henry.

    Would you recommend Mutant Mass after a workout only – or could you take it before and then straight after, say 2 scoops per serving instead of the full 4 serving?

    Thanks

    1. Hi Jake

      Taking a shake post-workout is a quick and convenient way to get the protein your muscles need repair and recover, however don’t get too hung up on timings and scoops.

      Look at the bigger picture – that is, your daily macro intake.

      Provided you’re getting enough protein/carbs/etc on a consistent daily basis and training hard you will hit your goals 🙂

      Let me know if you have any more questions!

  33. Hi Henry.

    Ii want to gain weight… which one is most effective.. Appeton Gain Weight or Mutant Mass?

    Thanks.. your answer is appreciated so much.

    1. Hi Eduard

      Thanks for your question!

      I am not familiar with the supplement you mention, but most weight gainers provide similar ingredients, so I presume Appeton is not too dissimilar.

      Speaking from experience, most gainers can be very effective when used correctly. Just remember to use them as a supplement to your diet and not as a meal replacement.

      I wrote a recent article which covers every box you need to be ticking on your journey to gain muscle mass – hopefully you’ll find it helpful!

      Let me know if you have any more questions 🙂

  34. Is this product good for women trying to lean up and build muscle?

    I’m a female, 22 years old, 121 lbs, 5’2 height.

    I usually eat 1500- 1800 calories averagely every day and am considering trying this product.

    What do you think?

    1. Hi Sadia, thanks for reading.

      If your goal is lean muscle I would avoid this product as it is far too calorific.

      Instead, try supplementing your existing diet (never replace meals) with a simple whey protein shake – maybe with some added fat loss ingredients such as green tea extract etc.

      Combine this with a decent weightlifting routine and some HIIT cardio, and you should, with some patience and hard work, achieve your goals.

      Hope that helps – and good luck!

      PS – Feel free to email or tweet us any time with further questions 🙂

  35. Very stupid reviewer:

    “Let’s face it, Mo Farrah might be able to run a mile in 3.30 minutes, but tasked with ordering a round of WKDs at Wafou Norwich on a busy Wednesday night? No chance!”

    I don’t know who Mo Farrah is, if running a mile in 3.30 min is fast or slow, what WKDs are, what is Wafou Norwich, what happens exactly on a busy Wednesday night, and to be honest, I don’t think Wednesday nights are busy at all, since most people are at home, etc!

    You expect us to understand that bullshit?

    You are writing publicly as if you speak to your schoolmates who share the same brains with you.

    1. Maybe you need to expand your horizons a bit – presumably you’ve got a computer and presumably you’re au fait with ‘Google’?

      Why not find out for yourself rather than boring us with your ignorance…

    2. Hi Ged.

      Wafou was a nightclub in Norwich.

      An extremely classy establishment… Hooch for a pound and Wonderbras get in free.

      It’s since had its licensed revoked for “excessive drunkenness”… but not a day goes by that I don’t think about it…

  36. Hi, just want to ask, what will happen if you take Mutant Mass without working out?

    What could be the possible bad effects if one’s not working out while taking this…?

    1. Hi Lordina.

      You will put on a lot of weight… and none of it muscle.

  37. Hi, this review is really helpful, I just wanted to ask though, I have an incredibly fast metabolism but I’m looking to put on weight (mainly around my thighs and bum and maybe boobs too), if I drink this according to he guidelines do you reckon this would happen?

    Thanks in advance for your help!

    1. Hi Alexis.

      First off, in the same way that you can’t spot-reduce fat, you can’t spot-increase it either.

      In other words, you can’t just add weight and thickness to your boobs and bum – especially by drinking a weight gainer like Mutant Mass.

      Instead, focus on a weightlifting routine comprising compound movements such as squats and deadlifts and get lots of protein in your diet to support muscle growth.

      By developing strong glutes, hams, etc, you will be some way to achieving the curvy look you are after.

      Hope that helps, let me know if you have any more questions.

      Henry.

  38. Hi Sir…

    Now I’m 24 years old and my body is slim fit… and I’m not doing gym or any workout.

    But I want to improve my body…

    Any tips ??

    1. Yes – get off your arse and workout!

      Only when you’re training consistently and eating well should you consider supplements.

      They are not some kind of magic solution.

  39. Great review, I’ve been using the weight gainer from Bulk Powders and works great but still don’t reach my 6000 kcal daily target, will try this and write my comments.

    1. Hi there, is that Complete Mass you’re referring to?

      Top product and great value for money, highly recommended.

      Anyway, let us know how you get on with Mutant Mass, I’m sure it won’t disappoint!

  40. New to the gym scene.

    I’m curious, does ‘dirty bulking’ with products like MM make the slimming part of the cycle more difficult compared to ‘clean bulking’ with lower calorie products?

    1. Yes, unequivocally so.

  41. Fantastic review mate!!!

    I agree with you on every point.

    Mutant Mass FTW!

  42. What’s your weight before taking Mutant Mass??

    And what after?

    1. I can’t remember the exact figures now, but, as I mention in the article, I put on half a stone, which is around 3.2kg.

  43. Now I want to buy this product on one conformation message…

    Is there any side effect in future by using this…????

    1. Hi Rajesh, the only side effect I noticed, as mentioned in the article, was extreme flatulence.

      I was farting like a fucking brewery horse, but that’s par for the course with most mass gainers.

  44. Hey, great article.

    I’m 23, 62kg and 183cm.

    Got my Mutant Mass today hoping I’m able to gain some weight.

    I’m really skinny now, mostly due to the lack of fat.

    There’s even these holes between my muscles where there is just skin and bone.

    I’ve been eating like a horse for a long time, without gaining.

    Do you think I’ll gain fat all over the body, or mostly around my stomach?

    Thanks

    1. If you’re working out and eating sensibly, you should be able stave off too much fat gain.

  45. Hi again Henry, I’m one of those who asked your opinion about Serious Mass in one of your reviews:

    http://www.gym-talk.com/optimum-nutrition-serious-mass-review/

    I’ve gained 10 lbs from 110lbs and I’m now 120 lbs – with the Help of Serious Mass.

    I’m 120lbs and 5’6″.

    Now, I’m planning to take on Mutant Mass.

    I’ve purchased 15 lbs of Mutant Mass.

    My friend computed if Mutant Mass has the same grams per serving as Serious Mass, Mutant Mass has more calories per serving compared to Serious Mass, because Serious Mass has more grams per serving than Mutant Mass.

    I’ve seen many people complaining about having hard time taking this because they’ll end up pooping in the toilet.

    How should I take mutant mass?

    1. OK I’m starting to poop always while using Mutant Mass and starting to have a lot of pimples & acne.

      Is this because of Mutant Mass?

      And I’m hardly getting any weight with this unlike Serious Mass.

      Or I’m just using it wrong?

      I’m taking 2 scoops per shake and I’m drinking 2 shakes per day – because 1 shake with 4 scoops makes me shit a lot.

      Am I doing it wrong?

      Thank you

      1. Increased bowel activity is certainly down to taking a mass gainer, as you’re body is processing a shitload more calories than it is used to, and a lot of this will be waste.

        Personally, I have never experienced acne as a result of protein supplementation/lifting weights, however there is certainly some research out there that suggests protein shakes can lead to acne in some people, as it can affect your hormones.

        One recommendation is to avoid non-whey or non-milk protein shakes, as milk contains certain hormones which can cause acne.

        Try an egg-white based protein, for example.

        To answer your last question, if you are supplementing a diet which is already rich in protein – and not replacing any meals – then you should certainly be putting weight on.

        Results won’t happen overnight – just keep at it and you’ll see changes.

    2. Now I have a big belly, is this natural?

      I didn’t gain much weight and I got a belly now.

      What do I do now, should I stop using this and use Serious Mass again?

      1. Mass gainers do lead to a little extra fat gain – but just keep hitting those big compound lifts and muscle gain should outweigh this.

    3. Hi Jon.

      Will recently wrote a comparison of most of the mass gainers on the market (at least in the UK anyway), this should answer some of your questions:

      http://www.gym-talk.com/best-uk-mass-gainers/

      With regards to taking Mutant Mass, just drink it between meals – not as a meal replacement – alongside a healthy high-protein diet.

      1. It’s been several months now after you gave me an instruction on how to take Mutant Mass.

        Before it made me bloat with little exercise… now I’ve tried it once more to give it a try and I have no more money to buy Serious Mass I told my self nah, I’ll just stick to Mutant Mass til I get enough money.

        After 1 week of drinking this crap it made me fat again with a full week of intense exercise.

        Can you please help me remove this fat I’ve gained on Mutant Mass.

        Never again will I take this crap it made me poop a lot and fart and gave me a huge amount of fat.

        Thank you…

  46. Hello there I have a question.

    Before I buy this product I was wondering if it would help me gain some weight because I am really skinny?

    1. Yes, use this as a supplement to your diet, and not as a meal replacement, and you’ll certainly gain weight.

  47. In 1 scoop of mutant mass how MM of water???

    1. As much or as little as you want.

      If you want a thicker consistency, use less water.

  48. Just ordered my first 6.8kg bag of this gainer… I got a MUTANT BCAA 9.7 (348G) for free with it, so it was quite a deal I couldn’t miss after some positive reviews on this page.

    The negative one I didn’t read 😉

    1. Hi Darmar, thanks for the comment, and good luck with your training!

  49. Hi bro, just a quick question.

    I drink 2 shakes per day and divide the 4 scoops in to two.

    One is morning and other is post workout.

    Can I drink the half of the first shake from morning then the remaining half of the first shake during lunch?

    1. Sure – try to focus on your daily macros rather than fretting about how many scoops and what precise time to take the shake.

  50. Hello sir,

    I read the review on Mutant Mass gainer.

    And so I think I can get help from you.

    It would be great help to me if you can suggest me the workouts and the supplements for me.

    I’m 20 years old with height 5’7″.

    I’m going gym from last 2 months.

    Before starting I was only 53.8kg.

    In these 2 months I gained some weight and now I’m 57.5kg.

    My skeletal muscle mass was 24kg which increases but its only 24.7 kg now.

    I gained fats most of it.

    So sir what workouts will you suggest to me to gain the weight with muscle bulk and what supplements should I take and what diet will you suggest to me.

    It will be a great help to me sir if you can suggest me some, so that my friends at college no more call me skinny.

    1. I would prescribe a 3-sessions-per-week full body routine, such as Stronglifts 5×5 or Reg Park’s 5×5.

      We have articles on lots of them here: http://www.gym-talk.com/training/workout-reviews/

      With regards to supplements, I would suggest only a whey protein supplement to help you top up your daily protein intake (goal should be around 1-1.5g per pound of bodyweight per day).

  51. Hey I’m 16 and I wanna gain some mass.

    My weight is 123 lbs.

    What would you recomend: Mutant Mass, Mass Extreme Mass Gainer or MP Combat xl.

    Note I want the least fat with more muscle mass gaining and no side effect.

    1. If you’re intent on “clean bulking”, then I would avoid a mass gainer altogether, as it’s simply not going to happen.

      At your age, I would just focus on eating and training well and enjoying yourself.

      Stick to full-body training, eating nutritious whole foods, and getting in as much rest and sleep as you can.

  52. Good day, I am 17 and turning 18 this December.

    I am planning to buy my first supplement and thinking to buy this one.

    I am almost up to my 1 year gym journey.

    I am skinny at first but I already gain slight muscles.

    Will this help me bulk up since I am already cut and my muscles are visible but not as big tho.

    I also eat 4 times a day with lots of carbs tho.

    So can this supplement help me with my fitness journey?

    1. Yes, this will help you bulk up, just make sure you use it alongside a productive training routine (I would suggest a three day per week full body workout with lots of compound lifts) and a nutritious high-protein diet (using Mutant Mass to supplement and not replace meals).

      Also ensure you’re getting lots of rest and recovery (at least 9-10 hours uninterrupted sleep every night) and drinking lots of water.

  53. Would it be good if I take it early morning then whey protein post workout?

    1. I mean mutant mass in the morning then whey protein post workout.

      1. Don’t get too hung up on when to take the shake – rather look at how many kcals/grams of protein you’re getting per day.

  54. Please help does this Mutant Mass affect sexual ability and fertility.

    Thanks for answering please answer me fast.

    1. No, it should’t do.

      Apologies for the late reply – hope this wasn’t a mid-coitus emergency!

  55. I started using Mutant Mass for the past 2 days, suddenly my poop became loose and started farting so much?

    Is this normal for first time users or I may just be lactose intolerant?

    What other brands of mass gainers can you recommend to me if Mutant Mass would not be good for me?

    1. While I’ve certainly experienced flatulence (Mutant Gas), I’ve never had the runs.

      If you’re going from a fairly low calorie/low protein diet to two servings of Mutant Mass per day, then that’s quite a lot for your digestive system to process.

      With that in mind, I would suggest reducing the serving size for a while and seeing how you get on.

      And try mixing the powder with more water, which should make digestion easier.

      If that fails to work, I would suggest discussing the issue with your GP.

  56. I am 5’10” 304lbs (from 315lbs).

    I have been working out naturally for the last 2 1/2 months (3x a week) 30-50mins elliptical/stepper + machine weight training.

    No free weights training because I am not comfortable with it.

    My progress is really slow – both in terms of weight loss and muscle gain and I want to speed it up on my 4th month.

    I am planning to buy Mutant Core L-Carnitine and Hydroxycut Hardcore Next Gen as my fat burners.

    I also see this Mutant Mass Muscle Gainer on display and some of my gym mates say it tastes really good.

    Questions: can I have all this stuff altogether?

    Or should I concentrate on weight loss for now?

    Any other tips/advice?

    Thanks.

    1. If you’re serious about muscle gain then you’re going to have to start getting comfortable with free weights – machines won’t cut it I’m afraid.

      Forget supplements for now, as they should really be the last piece of the puzzle after training and general nutrition.

  57. Hi bro!

    Should I stop drinking Mutant Mass during rest day on my gym routine or not?

    I’m new to this supplements though.

    I buy 15lbs as recommended by one of my friends who loves gym.

    I’m typically skinny type guy, 5’9 tall and 60kg.

    1. No, supplement your diet every day, you need to maintain a massive calorie surplus.

  58. Hello Henry please clear my doubt.

    Mutant mass gainer doesn’t contain any steroids?

    1. No Tej, it doesn’t contain any steroids.

  59. Does it really gave you strength or just muscles?

    1. Consistently upping your calorie and nutrient intake will certainly aid you in developing muscle and strength – providing the rest of your regimen is in order (diet, training, recovery, etc).

  60. I bought this product… does it cause any side effects?

    1. I experienced excessive flatulence – as have many others.

      Aside from that, I didn’t notice anything else, but I would suggest consulting your doctor if you do, as everyone is different.

  61. Thanks for the info!

    Planning to buy this thing because I’m having a hard time in reaching my requirements (carbs and protein) because I can’t eat 2 cups of rice at school.

    I’m supposed to drink this once a day right?

    Because some people drink their shakes twice a day and I thought: that’s too much.

    1. It all depends on the individual but I would certainly suggest two servings a day alongside breakfast, lunch and dinner.

      If you can’t stomach it, try starting with one shake then gradually build up to two.

  62. When is the best time to use Mutant Mass for the beginners like me?

    1. You need to get out of the mindset of the “what is the best time” to take protein.

      Instead, focus on being in a caloric surplus every day by eating nutritious, healthy food (meat, fish, eggs, fruit, veg, milk, etc).

      Get at least one gram of protein per pound of body weight every day.

      Do this consistently, train hard with heavy barbells, sleep well, and everything will fall into place.

  63. Hi please help me.

    I am 18 years old and weighing 45 kg, 5’5 tall and I am skinny as twigs.

    I am desperate to get fat at least or of course much better if it becomes muscle.

    Would taking Mutant Mass help me to get bigger in a short period of time?

    Thank you so much.

    1. Yes it will, providing it’s putting you in a big caloric surplus.

  64. I am drinking Mutant Mass at the moment.

    I see its taste is really good.

    I really want to buy another bag!
