Suitable for both men and women, Grenade Thermo Detonator is perfect if you"re looking for an effective fat burner with natural ingredients to help shed a few extra pounds. It delivers in every area that a thermogenic should, lovely stuff.

Grenade Thermo Detonator floated across my radar a few years ago but I immediately ignored it.

Almost all weight loss supplements are overhyped and this product, with its gimmicky macho marketing, screamed branding over substance.

I quickly decided this was a product reserved for twenty-something males who will literally swallow any old claptrap provided it comes in a shiny wrapper and is endorsed by Craig David.

This mild disdain was further cemented when my friend Simon started raving about it.

Imagine Gareth from the Office wearing an All Saints cardigan, drinking a skinny caramel latte, and crying on the lat pull down machine because his wife’s just caught him sending pictures of his ballbag to another girl.

This is the sort of clientèle we’re talking about here, a massive mustard cock of a man.

However, to my surprise, the product started to get some good reviews from a lot of respected guys in the supplement industry, as well as some noticeable awards, and after receiving many requests from our readers to review it, I decided to jump off my high horse and give it a go.

And I have to say, as much as I really, really wanted to hate this product, it’s actually a genuinely awesome supplement and easily one of the best weight loss products currently on the market.

Product overview

grenade thermo detonator fat loss pills

Grenade Thermo Detonator is first and foremost a fat burner.

It contains all the classic fat burning ingredients which should be the cornerstone of any product of this genre, such as caffeine, green tea, cayenne and orange peel extract.

These are all safe, standard ingredients which have been scientifically proven to help with weight loss.

You can buy all these ingredients across the counter.

There is nothing remotely dodgy here, such as DMAA, or anything that will make you jitter and spume like a crackhead with rabies.

And what’s good about Grenade Thermo Detonator is that it contains no dodgy propriety blends either.

It gives you the exact ingredients, something you’ll rarely find with any of these miracle “get shredded overnight” pills.

If you’re stupid enough to fool for these pills, you deserve to be fleeced of every penny you have.

However, there is an absolute avalanche of caffeine here (225mg per serving to be precise).

I personally handled the caffeine dosage with no problems, as I’m used to hoovering up litres of tea every day, but beginners and those receptive to caffeine should start with half servings and work their way to a full serving, as it’s very strong.

Also remember to steer clear of drinking too much tea or coffee while using Thermo Detonator (unless you enjoy anxiety attacks), and be careful not to get too hooked, because caffeine can easily become addictive.

i'm so caffeinated i can see sounds


I took Grenade Thermo Detonator for two months during my recent cutting cycle and lost 6kg, which I was pretty impressed with.

I took four servings a day, two pills in the morning and two pills midday before my workout (more than six hours apart, as instructed by the label).

While it’s primarily a fat burner, Grenade can also work as a pre-workout due to the high levels of caffeine.

It certainly managed to keep me focused after a long day at work, meaning I was still in the mood for an evening workout rather than a pot noodle and a wank.

Indeed, while dieting can leave you feeling lethargic like a deflated balloon, this product helps you keep energy levels up, and what’s more I experienced no crashes whatsoever.

It’s also important to bear in mind, as I’ve reiterated on numerous other reviews, that supplements are not miracle products.

You absolutely have to put the work in with your training and diet to see results.

So if you’re taking Grenade Thermo Detonator as instructed but sneaking in a few chicken kebabs along the way, don’t be surprised if it does naff all.

But if you’re eating clean and training hard, this supplement will definitely help you shed a few extra pounds.

My only criticism would be that this product doesn’t work very well as an appetite suppressant, as it is advertises, as I found it a test of will to avoid snacking.

However, this might be a personal thing, as I’ve seen many other reviewers who have said the opposite.

Side effects

I noticed a little bit of heartburn during the first few days, however after upping my water intake this soon went away.

Also – and this should be common sense – do not take Grenade Thermo Detonator before bed.

You will NOT be able to sleep one wink.

Moreover, if you have any kind of problems sleeping at all, I would definitely recommend steering well clear of this product.

Value for money

100 capsules will cost you around £30 in the UK and $40 in the USA.

So if you consistently take four pills a day you don’t need to be Carol Vorderman to work out this will last you 25 days.

Which, provided you use alongside a sensible diet and a solid workout regime, should provide great results and thus pretty good value for money.


Suitable for both men and women, Grenade Thermo Detonator is perfect if you’re looking for an effective fat burner with natural ingredients to help shed a few extra pounds.

This supplement delivers in every area that a thermogenic should, lovely stuff.

I would definitely use Grenade again and heartily recommend it to anyone looking to loose weight fast.

A rare case of an overmarketed product that lives up to the hype.

And, bottom line, this advert for Grenade is still one of the gayest things I’ve ever seen:

  1. This product is brilliant – best fat burner on the market.

    Have had many customers report results to me and have also seen the results with my own eyes!

    1. Hi Jack, thanks for dropping by.

      Definitely agree with your comments, it’s miles ahead of most ‘fat burners’ currently out there!

      1. This review I found to be pure rubbish I don’t really want to eat on them I feel more focused and awake value for money I love them and feel they really have helped I’m still newish to them but so far couldn’t complain I will say the only thing he was correct on is the heart burn thing.

        Try them take it slow train hard eat well.

  2. I mainly Grenade for a pre-workout.

    I tried dozens of preworkouts, and everything I have tried (Jack3d, C4, NO explode, Hyde, Black Powder, and many others) my body had adjusted to and was no longer effective in the energy department.

    Grenade gives me enough boost to go the gym after work and have a good solid workout.

    After 4 weeks I did up the dose to 2 pills at one time.

    I take a two week break between bottles, works great for my use.

    Not sure about the fat burning side, I eat clean and had been dropping weight (40 lbs) rapidly before taking Grenade.

    I also tried the new Hydroxy Cut SX-7.

    Overpriced and kinda disappointing.

    Good review man.

    1. Hi Paul

      Glad to see you’re getting some nice results 🙂

      I agree this works great as a preworkout, certainly one of the best I’ve used (although haven’t tried as many as you!).

      Good luck with your training buddy!

  3. I swear by Grenade!

    I’ve tried numerous products, but Grenade is the only one that has really worked for me.

    As a mother of three young boys under the age of five, I don’t have a completely dedicated life to bodybuilding but I squeeze in what I can, and I’ve found Grenade still works even if I’m slacking a bit.

    At the moment though, I’m using just Jodie Semtex… but it’s CRAP.

    Going back to Grenade as soon as I’ve finished this tub of Semtex

    1. Hi Sammi, thanks for your comment.

      Yeah, I’ve not heard great things about the Jodie Marsh supplements to be honest!

      Hope you have a better experience returning to Grenade, which I’m sure you will 🙂

  4. Hi Henry.

    Loved the write up about Grenade.

    Very funny and informative, especially loved the picture.

    Anything to say about Dedicate Dominate testosterone?



    1. Hi James

      Thanks for the kind words, it’s great to get positive feedback.

      As for Dedicate Dominate Testosterone, I haven’t come across this product. Personally I’m quite wary of supplements of this ilk, as with other gimmicks and fads.

      You’d be better off nailing the basics with your training and nutrition plan before wading into these muddy waters, as this will give you a much better return on your investment.

      Let me know if you have any further questions buddy.

  5. Awesome product.

    For getting an excellent result, keep a good diet.

    Start with low dose 1/day.

    After 3 or 4 days raise the dosage to 2/day.

    After 7 day can use 4/day.

    May be a visible result came after 15 to 20 days.

    Do not use 8 hours before sleep, it makes you on.

    2 cap on wake up and 2 before the lunch.

    Do not stop the use when you are at high dosage – stop it gradually like the starting.

    If possible use whey protein parallel.

    Increase your water level also, it works excellent.

    1. Hi Aswany, I agree that Grenade works very well when used properly alongside a solid diet and training plan 🙂

  6. Plz tell me how can you use Grenade fat burner and plz tel me said effect?

    1. Did you even read the review?!

  7. I can’t swallow these capsules, is splitting/biting them in two OK?

    1. So long as you’re consuming the capsules, I doubt the method of ingestion matters.

  8. How many days until the result of Grenade is visible on the body?

    1. That is an impossible question to answer, Inderjit.

      There are so many factors at play – diet, training regime, rest and recovery, genetics…

      But provided you are putting the work in at the gym, eating sensibly, getting lots of sleep, and, above all, being consistent, then you will see gains soon, I promise you that.

      Let me know if you have any more questions.

  9. Hi

    I’ve just ordered some of these.

    How many should I start with?

    I was thinking one in the morning and one before my workout (late afternoon say)…

    Would two be OK seeing as I am new to them?

    Also I normally take green tea capsules (450mg green tea and 11.25mg caffine).

    Should I knock these on the head while taking Genade?

    Thanks 🙂

    1. Hi Leanne, thanks for your comment.

      If you’re sensitive to caffeine I would definitely recommend starting out with just half servings – one in the morning and one pre workout.

      Even if you’re not, it would be a good idea to start like this – let your body acclimatise – and then dial up the dosage later if required.

      Also, you do not need to be taking a separate supplement, as you will getting enough green tea extract and caffeine from taking Grenade.

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


      1. Thanks for the info Henry!

        Do they have to be taken on an empty stomach?

        Obviously that would be harder with the afternoon doseage when I’m having my pre-gym carbs too – will that matter do you think?

        1. They don’t need to be taken on an empty stomach – but this does speed up absorption and thus affects you quicker.

          However, I would personally avoid taking this on an empty stomach just before a workout.

          You absolutely need fuel in your body to function at your best, so never sacrifice a decent workout in order to ‘optimise’ a fat burning supplement.

  10. Does it effect sex life?

    I heard many a thing like that so plz let me know actually if it affects it or not.

    Plz rply

    1. Hi Sameer.

      Fat burners shouldn’t effect your sex drive or ability to perform.

      However, if you’re cutting and, as a consequence, not getting much fat in your diet, this could lower testosterone levels which could impact your libido.

      Also, remember to do some cardio to keep your bloodflow up, and, failing all this, just bang back some Viagra – you’ll be in and out like a fucking sewing machine.


      PS – I am definitely not a doctor.

      1. And that’s science.

        1. “In and out like a fucking sewing machine” hahahahahaha.

          Excellent line, I’m having that!

  11. Good review bud, had me laughing my arse off 😉

    Anyways I’m on my second day of using this product and did get the heartburn you described but I’m just going to drink more water.

    I would not take any gimmick supplements out there – and F me there is a lot – but the reviews for this product seem legitimate.

    I am excited to see my results in the next 4 weeks because I know my training and diet will work wonders (trail running, boxing, weights).

    I have been training for 3.5 years without any supplements, the supplements that I have started using will help me break through the plateau I’m at.

    Realistically I think this product will aid me in leaning out.

    1. Hi Caolan

      Grenade is certainly not a gimmick – but, as I mention in the review, it’s no magic pill either.

      You need to be hitting the gym hard – consistently – and eating sensibly too.

      Good luck with everything – and let us know how you get on!

  12. I want to start using this product as I have been told it’s good.

    I need to lose some weight quick – but what is the best way when taking it to shred the weight?

    Any reply will help a lot.


    1. Hi William.

      Follow a workout programme comprising HIIT (High Intensity Interval Training) and compound weightlifting exercises (squat, deadlift, pull ups, etc).

      This will be a high highly effective weight loss routine.

      Combine this with wholesome, healthy food – for weight loss you should consume an abundance of protein and dial down your carb intake, especially High GI and starchy carbs.

      For a solid ‘shredding’ diet, take a gander at Jim Stoppani’s ‘Shortcut To Shred’:

      And, most importantly, make sure you are being consistent with everything!

      Follow this advice, along with taking Grenade, and you will see some awesome results buddy!

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


  13. Good review, rated 5 stars 🙂

    Quick question, I have used two bottles of Grenade (1X40 & 1X100) over the course of 3 months.

    I was thinking of starting with another 1X100 as I find this really good and it gives me ample energy for my workout.

    Is it safe to start another bottle? Your thoughts please.

    1. Thanks Kapsy 🙂

      If you’re getting results – go for it!

      Bear in mind, when used as stipulated this product is completely safe.

  14. After your review I will definitely be giving these a try.

    I have wasted ££££ on tabs that claim to work, the lasted being ONYX Alpha Black, which made my Poo Slimey and made me feel like crap.

    I’m going to order these tomorrow.


    P.S Love your review going to put it on my FB page

    1. Thanks Helen – I appreciate the share 🙂

      Good luck with the gains – and let me know if you need any help/advice!

  15. Nice review.

    I bought these initially for my girlfriend who is trying to lose a few pounds to be beach ready for holiday in a couple of weeks.

    It didn’t however go as planned as after a couple of days she started to get really bad headaches and did not feel in any way well while taking 2 a day (morning & lunch) so she gave them up.

    Not being the kind of guy that enjoys wasting money, I started taking them myself.

    However with the stuff I have used over the years (NO fat burners) I went head first into just taking 2 in the morning and 2 before workout!

    I have had only one side effect over two weeks of using them and it’s the only one I wanted – I have lost 5 pounds 🙂

    To put that into perspective, I have been cutting now for 5 weeks and was losing around 1 pound a week.

    So my conclusion is that they are definitely not for everyone, so if you have never used fat burners before ease yourself into them.

    Also I do not know if this is relevant or not but my girlfriend has one of the rarer blood types (can’t remember which one) but she does become very ill if she does not get enough iron in her diet.

    Unlike most other folk that just can’t poo and experience a lack of energy.

    Hope this helps for anyone considering buying them.

    1. Hi Patrick, thanks for sharing your experiences with Grenade.

      You’re absolutely right – caffeine-based products such as stimulants/fat burners elicit different responses in different people, so you need to find what works for you.

      Anyway, glad you’re seeing some impressive results – and if you ever need any further advice just let me know 🙂

  16. Hi!

    I just bought a bottle of this.

    But now I am a little skeptical of taking these after reading a lot of reviews on their one particular ingredient (bitter orange powder).

    I’d like to give it a try but I’m scared it might result in me getting a stroke.

    Also another concern is that I’m a petite girl and I’m not sure if I should up my dose to 4 caps a day.

    Another thing, they haven’t mentioned the percentage of Synephrine in one cap which makes me very uneasy.

    Please suggest.

    1. Hi there.

      I can assure you that Grenade is perfectly safe – in moderation of course – but to allay your concerns I would suggest speaking to your GP before taking this supplement.

  17. Hi.

    Is this safe to take with fasting?

    I’ve lost 4 stone and am struggling with the last one.

    I fast 4 days a week and workout 4-5 days and if so when should I take them as I fast all day…

    Love the review.

    1. Hi Michele.

      Can you elaborate a little on how you are fasting?

      Although intermittent fasting techniques have been shown to be effective, I would never, personally, recommend this approach or any other short-term fix.

      Fasting does not eradicate bad eating habits, impairs exercise performance, and is wholly unmaintainable in the long run.


  18. What is a good diet to follow and when should I eat while taking Grenade?

    I’ve searched online and its driving me crazy that I can’t find a decent one… what would you recommend?

    1. Hi Nordean.

      If you’re looking to minimise body fat while maintaining muscle mass, the major macro-nutrient that will need attention is your carb intake.

      Stick with complex, low GI carbs such as oats, wholewheat pasta, vegetables and slowly decrease your carb intake from about 1.5g per lb of body weight to 0.5g over the course of 4-6 weeks.

      It’s vital to gradually dial down carb intake, because if you suddenly slash carb intake your body will go into emergency mode and put vital stores on “lockdown”, thus you will hang on to body fat.

      Regarding your other macro-nutrients, roughly consume, per day, 1.5g of protein per lb of body weight and 0.5g fats per lb of body weight.

      Stick to whole foods here – steaks, eggs, fish, nuts – and you won’t go for wrong.

      Hope this helps, if you have any more questions feel free to ask!


  19. Hi, I tried one Thermo Detonator before breakfast and I felt kind of tired and had almost like a green feeling all day.

    Why could this be when I’ve heard so many good reviews out there?

    1. Hi Derek.

      As with all stimulants/fat burners, everyone will react differently, due to differing sensitivities to the ingredients (caffeine etc).

      My advice would always be to listen to your body.

      If you’re not “feeling” Grenade, don’t take it.

  20. Hey Henry, first of all amazing review, and I’ll be sharing it on my FB page, but I would like to ask you something.

    I’m doing intermittent fasting and so I only start eating from 12 noon to like 7,8 at night, SO when do you suggest I take the Grenade supplement, since every review says take one in the morning, but I’m not sure I should do that since I’m not having my breakfast then, although I do some cardio in the morning on an empty stomach.

    1. Hi Derek, thanks for the share, I really appreciate that!

      Fasting should have no impact on when you take Grenade – so carry on taking Grenade before your fasted cardio.

  21. Brilliant review… had me laughing in the morning when normally I go out and strangle anything that makes a noise.

    1. Thanks Andy 🙂

  22. Dear Henry,

    Nice review, all information needed as I started to take the Grenade from today.

    I just have a query.

    Do I have to take the second pill after 5 hours from the first one?

    Or would before work out work better?

    Just because if I do morning shift then I wake up at 4am (I take the first pill for an empty stomach) and I have lunch at 11.30am.

    Buuuuuut I going to the gym just around 4pm.

    I don’t really how shall I take them to be honest 🙂

    Thank you in advance.

    1. I would take it before you hit the gym.

      As I mention, it functions as a pretty neat little pre-workout supplement too!

  23. Hi Henry.

    I only got my Grenade pack today and was wondering… I do a lot of running at the moment, I haven’t been to the gym in months, is it safe to use Grenade for running, or would you advise to go to the gym as well?

    I am at 14% body fat and want to get to 8-9% body fat before I get back to the gym.

    I took one in the morning and one before lunch and felt great after I even did a 10k that evening.

    1. Hi Mark.

      Just take Grenade as directed, before any workout – be it running, swimming, lifting – and in the morning.

      Good luck with your goals, and if you have any further fitness questions, don’t hesitate to get in touch.

      Hit us up anytime on email, Twitter or Facebook.


  24. Hello.

    Amazing reviews.

    I had taken grenade and lost 5 pounds in two weeks.

    It was a really awesome moment to see me losing my weight on the weight machine.

    But after two weeks my weight increased weirdly and it touches the weight that I had before.

    It’s really strange that it only helped me out with two starting weeks & after that the weight comes to its original value…

    Can you please tell me why?

    I work out hard daily.


    1. Hi Husnain.

      It’s impossible to answer that question here, as there will be so many factors at play.

      However, if you’re working out daily, as you say, and eating well, I would be inclined to think that this weight increase is down to lean muscle gain.

      I would recommend ignoring the scale for now and instead look at your changing body composition as a progress indicator.

      Eat clean, train hard, be consistent, and you will see the results you’re looking for in the long term.

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


  25. I’m using this right now.

    It’s been 20 days consuming this fat burner at the same time I signed up for a gym membership.

    I lost 5 kg/11 pounds in 2 weeks, it was really amazing!

    I took 2 pills in a day (during dawn right after waking up and then lunch).

    It boosts my energy levels and I can do cardio for 2 hours, only fast walking with a little bit of incline + a weight workout and some other workouts for 2 hours.

    So basically I spend 4 hours in the gym, 6 days in a week…

    I know it’s bad to spend more time in the gym… but I’m not really pushing myself… I’m just having fun and the gym is so addictive… specially during morning… nobody is around!

    Yay for me!

    I could agree this pill/suplement is working but let’s not forget another important role such as eating healthy food, having enough sleep also working out.

    1. Hi Yurika.

      Glad to hear you’re getting some awesome results 🙂

      Fitness is addictive – just make sure you don’t burn yourself out, as enjoyment is key!

  26. Is blood donation okay with consumption???

    1. If you’re worried I would advise speaking to your GP, as I’m not a medical professional and would definitely never advise on such matters.

  27. I want to know how long I should use Grenade Fat Burner for?

    I use it for 2 months… and no results found… please help, how long should I use this product?

    1. Impossible to answer as there are so many factors at play.

      But if you are taking Grenade while doing the following, I promise you will see results:

      Eat healthy wholesome food, increase protein intake, train hard with big compound movements and HIIT, sleep, recover, drink lots of water, and be consistent with everything for a long period of time.

  28. Hello Henry.

    Hey I want to know if I eat one pill on an empty stomach in the morning?

    It will work or not?

    1. Hi Amar, yes, as per the instructions, take one serving in the morning ideally 30 minutes before breakfast.

      Supplementing with Grenade will help with your fat loss goals, provided you are training hard and eating correctly.

  29. Hi.

    Great review.

    I’ve just got some of these and look forward to putting in the effort and seeing some results.

    Can I ask though do you continue to use these on rest days or just days you’re training?

    Thanks in advance.

    1. You take them every day.

  30. Henry,

    A good review – cheers.

    Some advice though if you don’t mind?

    I’m no stranger to a gym, and started a GVT routine back in October.

    Whilst the results have been impressive, gains of just under 8kg (I eat like I’ve got a tape worm!), I have also put a “bit” of timber on the old mid-riff.

    Would this help with shedding some belly fat whilst also enabling me to maintain/increase muscle mass without having to dip into a calorie deficit?

    I’m loath to change my routine and calorie surplus (around 300-400cals per day) but would like to shift some timber at the same time – too much to ask?



    1. Hi Paul.

      Yes, the added fat burning ingredients in Grenade should help you move some of that stubborn fat, provided the rest of your training/diet regimen is on point.

      In addition, try upping the intensity of your workouts as well (interval work, more heavy compound lifts, etc) to increase fat burning efficacy, as this will likely have a much more significant impact.

  31. Hi,

    I am using it from 1 month and I can see the results, but let me know can we drink black coffee and green tea using these capsules?

    Like before workout consuming this capsules on empty stomach as per workout can we take black coffee??

    1. Yes – but don’t overdo it, as you’ll be ingesting an obscene amount of caffeine.

      My advice in all cases such as this is to listen to your body, as everyone has different sensitivities to caffeine.

  32. I have started using this product from today with a good diet and 30 mins cardio after weights session on an empty stomach.

    However I am a little put off now after seeing side effects such as strokes and death!

    1. Sounds like bollocks to me – what’s the source?

  33. Hey I am currently only on a calorie deficit but not working out can I use these pills?

    Will they affect without workout?

    1. Although this product can definitely help shed a few extra pounds when used correctly, I would not recommend it in your case, seeing as you are not exercising at all and are in a calorie deficit, so you’ll simply starve your body of what it wants.

      Focusing on a more sustainable approach is going to yield far better long term results.

  34. Hi.

    I’m using Grenade from last 10 days n eating clean n doing workout from 2-2.5 hrs but my weight is not going down.

    I dnt know I’m very confused so if anyone can help me to sort it out it would be great.

    1. Hi Sonal.

      10 days is far too short a time to expect results.

      Keep at it and the results will come.

  35. Am 96kgs now I need to reduce at least 15 kgs.

    I go 5.5kms jogging 4 days in a week and weight training 3 days but the weight loss result is low.

    If I take Grenade, 2 pills a day with 6 hrs interval, fat loss will be increased or not?

    Ned few suggestions pls…

    1. While supplements such as Grenade do help a little with fat loss, most of your results will come from refining your diet and workout regimen.

      With that in mind, I would suggest, firstly, adding more intensity to your workouts.

      Focus on high-intensity compound lifts (squat, deadlift, bench) and high-intensity cardio (boxing, sprints, etc) instead of jogging.

      Diet-wise, focus on eating healthy and wholesome high-protein meals with lots of vegetables.

      Dial down carb intake and don’t err away from foods high in fat – I would certainly recommend the paleo/caveman diet which prescribes this approach, as I have had much success with this.

      Hope this helps as a starting point – do let me know if you have any further questions.


  36. While I’m using Grenade should I take l-carnitine, or it already contains l-carnitine?

    1. I wouldn’t bother personally – adding in L-Carnitine will have a negligible effect, Grenade already has a handful of other fat-burning ingredients (green tea etc).

  37. Hi.

    I am using Grenade for the last 4 days, but even a single day I didn’t feel energetic.

    I am taking 2 capsules a day before 30 minutes of workout…

    What is the reason????

    1. It is impossible to say without any other information.

      I suspect it may be because you are starving your body of calories/nutrients/carbs in a effort to lose weight, or maybe you’re not getting enough sleep and recovery, but, either way, I cannot say for certain.

  38. Hi Henry

    Are there any side effects on sexual life after using this?

    1. Hi Rohit.

      As I mentioned in one of the comments above, taking a fat burner should not directly affect sexual performance.

      However, if you’re dieting, lack of adequate nutrients, especially fats which have been proven to impact testosterone levels, may be affecting your libido.

      Focus on getting some good saturated fats and monounsaturated fats in your diet (steaks, olive oil, nuts, fatty fish) – but avoid trans fats (fried food, cakes).

  39. Hi.

    I am trying to lose a lot of weight and of course gain muscle.

    Today I bought Betancourt B-NOX and Grenade Thermo Detonator.

    Can I use one as prework out (Betancourt B Nox) and the other as a fat burner (Grenade)?

    1. Using both is a waste of money in my opinion – I would just stick to grenade and use it to double up as your pre-workout.

  40. Hi Henry.

    Such a brilliant review of the product!

    And the answers to the questions make it even more simpler for me.

    I am starting with one pill so would you recommend me taking it in the morning or before my workout session which is in evening?

    Also have this thing in mind about losing muscle mass!

    Do I have to increase my cardio or is it just fine to restrict myself to the usual pre and post cardio of 20 mins each along with a body part and abs/sides?

    1. Thanks Pulkit, appreciate the comment 🙂

      Take it before your session, Grenade works great as a pre-workout.

      Cardio isn’t going to waste your muscles away, you’ll be just fine.

      Moreover, it’ll help considerably with achieving a lean, muscular look.

  41. Hi, I am starting cardio 1 hr, so I use this pill for weight loss?

    Pls answer.

    1. Yes, taking Grenade will certainly help, just don’t expect it to be a magic bullet.

  42. I usually use GAT NITRAFLEX as my go-to preworkout.

    Can I use NITRAFLEX as a substitute for the second dose of grenade?

    Or shouldn’t I?

    1. Not familiar with that supplement, but if it’s just a standard pre-workout, then this shouldn’t cause any issue.

  43. Hi, I would like to find out am doin training in gym I get healthy meals n pre workout n protein aswl I started taking 4 a day in the morning b4 breakfast n other 2 in the evening. It is the right way to take them jus want lean muscle?

    1. Yes, that’s fine – just remember to keep your diet on-point and include plenty of cardio and compound lifts in your exercise regimen.

  44. Hi, is it safe to take these after having 2 brain hemorrhage 10 years ago and now suffer from black outs I’m bk on my feet now at gym 5 times a week and running 15 mins every morning just st want to loose my belly fat 🙁

    1. Please consult a GP – I am in no way qualified to advise on this.

  45. Hi Henry plzzz tell me about fat burner & any side effects.

    1. Try reading the article…

  46. The label states that minors under the age of 21 should not take grenade, but is it possible to take a lesser dosage?

    1. Follow the label, those instructions are there for a reason.

  47. I have started GTD just yesterday.

    On the first day, I went home 7pm, took 2 pills and started walking fast for about 10km.

    I went to bed 12am and couldn’t sleep whole night plus too much headache whole night and next day also.

    What would you suggest?

    Shall I take it 4 or 5pm at office and start walking after I go home or what?

    1. Owing to the very high caffeine content, it is generally not advisable to take Grenade in the evening (I myself also struggled to sleep on occasion).

      Try taking it earlier in the day and see how you get on.

      If the side effects still persist, listen to your body and stop taking it.

  48. Was wondering if you can still build muscle while burning fat with grenade?

    1. Yes, provided you are training and eating correctly.

  49. Dear Henry

    How would you compare this to Lipo 6 RX… which is more effective?


    1. Sorry, have never taken Lipo 6 RX, so can’t comment.

  50. This review is beyond hilarious!!

    Agree with all of your points though, I have just started using Grenade and really liking it thus far.

    Good to know that the heartburn went away with a higher water intake, will have to increase mine.

    Are you still using Grenade?

    If yes have you noticed the long term benefits?

    1. Cheers Jessie, appreciate the kind words.

      I use it every time I want to really lean up (usually before a holiday), so have never used it long-term so to speak.

      It always delivers, great product.

  51. Can we have a cup of tea after having this capsule empty stomach before hitting gym?

    We consume ginger tea which contains tea, crushed fresh ginger, splenda sugar free with low fat milk?

    1. You should be fine – but listen to your body, it’ll tell you if that’s too much caffeine.

  52. Great article!

    A great read.

    Just got a tub, will give it a go!

    1. Cheers Kyle, appreciate it.

      Good luck with your training, hit me up if you have any questions.

  53. Hey Henry.

    Thanks fort the review, I have been using these while cutting over the summer but my q is would you take these if you are trying to do a clean bulk or would it impact on my gainz!

    1. Personally, I wouldn’t take a fat burner during a clean bulk, as you don’t want to be burning more calories than necessary.

      Plus, Grenade acts as an appetite suppressant, which is going to be counter productive to putting on weight.

      If you really want that clean bulk, you’re just going to have to be extremely strict with your diet.

  54. Hi all.

    I’ve started taking the Grenade Thermo for 3 weeks now and I’ve got say I’ve seen a massive difference in myself, very pleased with the stuff.

    But I’ve got a question to ask, I’m having a week off training next week, should I carry on taking them as normal or should I stop?

    Thank you.

    1. Yes, keep on taking.

  55. Loved the review Henry!!

    Fab product!

    I’ve tried many and unfortunately none will cut it.

    I’m a young small built female.

    And only recently found out these were a fat burner.

    I use them as a pre-workout.

    I accidentally bought the Grenade ketones and they gave me a serious case of ‘look at me the wrong way and I’ll stab you with a barbell’.

    I’m not aggressive, in any way I don’t think…

    I take 2 before I hit the gym and it gives me enough push and no jitters or sick feeling.

    My hubby bought them (because of their macho appearance… in my opinion) but he wasn’t a fan as he didn’t feel the jitters.

    His loss is my gain!

    Thanks heaps Henry,


    1. Great to hear it’s working Jade, keep it up!

  56. How long is the burning sensation meant to last for?

    I took one tablet when I woke and one 30 mins before lunch and I still have the burning 14 hours on?

    1. That’s not typical, I would discontinue if it causes prolonged discomfort.

  57. Great review!

    I adore Grenade products, I’m just moving on to trying out the Black Ops capsules.

    Along with their Carb Killa bars the Grenade products always feel high quality.

    Was wondering though, I usually take a pre-workout before the gym, so am planning on taking Black Ops only in the morning and my pre-workout as usual before my evening session… will this be too much, or will the Black Ops and pre-workout be OK to take with such a long timeframe in between the two?


    1. Really depends on your own tolerance, listen to your body.

  58. I recently started trying Grenade Killa Ketones could you do a review on these?

    I’ve only been using them for a couple of days so can’t say if they do much yet.

    I’m using them as a pre-workout they do help a bit I think – or is it all in my head lol?

    Reviews would be good.

    1. Hi Kerrie, will certainly look into reviewing them, thanks for the heads up.

  59. What would be the cut off time for taking?

    I train after work at 5:30pm and often have trouble sleeping after taking grenade at 5pm.

    1. Test and see, everyone’s different.

  60. What should I prefer food while taking grenade black ops fat burner?

    1. Eat healthy, nutritious food and avoid crap.

      If you don’t know what that means, educate yourself:

  61. Plz tell me about fat burner sex life.

    1. It should have no effect on your sexual performance Sumit.

      Dare I ask – what in particular are you referring to?

  62. Started this a week ago on a healthy diet and gym regularly, already lost 3kg with Grenade.

    Defo getting fitter for holiday!

    1. Great to hear it George, keep it up!

  63. Hi.

    I need to lose weight about 3kg as soon as possible for my champion.

    Is it effective to do that with diet and exercise?

    1. What is a ‘champion’?

      To your second point, yes, it will be effective if you eat and train well and consistently.

  64. 11.30pm and I’m wide awake convincing myself that this one tablet will finish me off!

    What is in this stuff?

    I ordered this to go with my healthy eating and exercise regime, I have just had a baby so am keen to lose any extra weight.

    I feel awful and it’s safe to say I will not take anymore.

    Anxiety kicked in big time… awful awful awful I just want to go to sleep but I’m wide awake (taken 1 tablet 10 hours ago).

    1. Steer clear… definitely not a product for those with a low caffeine threshold.

  65. Hi there, I really enjoyed reading your feedback.

    I brought Grenade about a year ago and was working really hard on my body, but at the time the formula was exactly what I needed.

    My body needed a break from these type of supplements and then when I started again, even one pill was WAYYYYY to much.

    Even when taking it early it was too much for me to handle.

    Not sure if there’s any products you could recommend, that would have about the same results without this amount of drive.

    Been looking online for samples, because I don’t want to get stuck with a huge bottle of product because it was too much for the body.

    Thanks again in advance.

    1. If your body responded badly the second time around, I would stick to trying to achieve results purely with the basics, supplement-free – that is, consistent training, a healthy diet and plenty of sleep.

  66. Is there any expiry date of Grenade Thermo Detonator?

    1. Check the packet.

  67. Hi dude,

    I am taking Grenade fat burner capsule for the past 1 week, is it advisable to avoid drinking coffee and tea?

    Can you please help me with this.

    1. Depends on your caffeine tolerance.

      I would certainly avoid too much coffee or you’ll be tripping ballsacks.

  68. I am taking Grenade capsules but due to personal reasons I am not able to take it continuously.

    Will it be effective?

    Please guide me

    1. Without consistency you will not achieve the desired results, end of.

  69. Mate what a review.

    Overall just started these fat burners and honest I’ve never felt better!!

    I feel more energised and just generally great!

    I’m currently taking 2 capsules on a morning at 8:00AM and then two half an hour before my dinner at 12:30.

    However, I don’t usually work out till after work (4:30).

    To get the best results should I leave the second lot of tablets till before work out or before dinner?

    1. Take them before working out for that sweet caffeine boost.

  70. I’m 16 years old, 83kg and 5″11.

    I’ve been going to the gym for 2 years and I can take caffeine well.

    I’m looking to lose weight fast for personal reasons.

    Do you recommend me taking it and will it stunt my growth?

    Aslo should I only take half of the required amount?

    1. Taking Grenade will help – but the biggest factors in weight loss will be your workout routine and general diet.

      Can you provide me with some more info regarding to the above?

      1. I go to the gym everyday for about an hour and I fully know what I am doing when I go.

        I have started doing hiit cardio and my diet is good often taking in 2100 calories a day.

        Will it stunt my growth and can you WhatsApp me so I get a quicker reply 07476002513.

        1. No Heera it won’t stunt your growth

  71. Great review!

    I got this product a few days ago and it seems to work as described.

    Please tell me what type of food or what type of diet to consume whilst using this product?

    1. I know this is not going to sound specific enough for you, but just eat healthily and monitor calories in versus calories out, it’s really quite simple.

      If you don’t know what ‘healthy’ is, it’s time to educate yourself…

  72. I have taken Grenade overall twice now.

    First period was pre-pregnancy and now after 8 months of giving birth I started again.

    I have to say Grenade have been working for me like a charm.

    With first period I lost almost 5kg that i wanted to loose hand in hand with working out consistently.

    No side effects.

    Now when I started with my second round to lose some extra kg’s and get back in shape after pregnancy, I have to say – I can see some side effects that were not there on the first time.

    Stomach burns.

    Especially when I haven’t had enough water or eaten well during fast office hours.

    Grenade gives excellent energy boost and heat effect during workout but one must take in consideration to have proper nutrition and TONS OF WATER as well since metabolism is boosted.

    So what I have done in both periods and it has helped: For a couple of weeks I had only 1 pill in day (in the morning) before workout.

    If my body gets used to it, I’m turning to 2 pills by day etc.

    For me that 1 pill ONCE a day helps a lot.

    Tho I’m not that big of a person as well 🙂 170cm and 55kg 😀 but still 🙂

    All in all great product, but people shouldn’t expect that it doesn’t have any side effects or will do miracle right away.

    Just only consuming this won’t do much – people, GYM and quality eating is also mandatory at this point.

    PS! Also If Grenade or any other supplement makes your stomach burn, the thing that helps is to consume Lactobacillus supplements (yogurt that includes the Lactob. Tablets, powder, fermented milk etc that are enriched with the previously named friendly bacteria) – they will support stomach micro-flora.

    Thanks 🙂

    1. Hi Saskia, thanks for taking the time to leave a comment, it’s appreciated.

      You hit the nail on the head – without a quality routine and diet this is not going to be a magic bullet.

  73. Ok, this is certainly the funniest review I have read in a long time least to say.

    I have been using it as a pre-workout and it works wonders for me.

    On the other side I am trying not to take one sneaky tablet on my recovery days as a booster because I feel so knackered after a heavy workout day.

    1. Hi Zuzana, great to hear it’s working for you, please let me know if you have any questions!

  74. Do you experience any hair loss with this product?

    1. No you shouldn’t – if you do consult a doctor.

  75. I am on week one of this and I have only taken one pill a day.

    Given I am 32 y/o and a woman, I lift every day and eat well.

    This suppresses my appetite a lot.

    I have lost 3 pounds this week from it.

    Clean eating for the majority of the week!

    1. Glad to hear it’s working out for you Jennifer, feel free to get in touch if you have any questions.

      1. Hiya, I started taking 2 capsules first thing in the morning.

        My heart rate was surely higher than comfortable, and I don’t have high blood pressure.

        Is that normal for everyone who takes them.

        I definitely feel burst of energy throughout the day.

  76. Hi amazing review!

    I just wanted to check I take these 2 in the morning and then 2 early evening few hours before dinner, I do not have big lunches as I intermittent fast till lunch time then have fruit and some lean protein.

    I have seen some positive results so far but just wanted to confirm this will work in the long run and is safe to continue this schedule?

  77. Hi Henry,

    Exactly what I need to hear from a review, objectiveness and common sense, very helpful thanks.

    Definitely going to give it a go, btw your style of writing had me in tears, really enjoyed reading it.

  78. Just ordered some to boost my workouts – wish me luck 🙂

  79. I was SOOOOO disappointed when my box of Grenade Thermo Detonator arrived to see that there are 25mg of PHENYLALANINE per 2 capsules!!!!

    That stuff is like poison to my nervous system and makes me shake all day.

    Will never buy this product again.

  80. Only problem I found with them is the heartburn the first week was so bad I felt ill every time for that couple of minutes, it was terrible, could taste the orange peel, but like you said after upping the water intake soon went.

    Also my sleeping now is hard to switch off, so make sure you don’t leave it late to take them!
