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.

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 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.
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.
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:

The best place to buy Grenade Thermo Detonator is usually at Amazon where you can usually find it for much lower than the recommended retail price.
If you’ve tried this supplement, or any other fat burners or products from Grenade, I’d love to hear from you!
Get in touch via the comments section below.
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!
Hi Jack, thanks for dropping by.
Definitely agree with your comments, it’s miles ahead of most ‘fat burners’ currently out there!
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.
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.
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!
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
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 🙂
Hi Harrison.
Loved the write up about Grenade.
Very funny and informative, especially loved the picture.
Anything to say about Dedicate Dominate testosterone?
Cheers
James.
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.
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.
Hi Aswany, I agree that Grenade works very well when used properly alongside a solid diet and training plan 🙂
Plz tell me how can you use Grenade fat burner and plz tel me said effect?
Did you even read the review?!
I can’t swallow these capsules, is splitting/biting them in two OK?
So long as you’re consuming the capsules, I doubt the method of ingestion matters.
How many days until the result of Grenade is visible on the body?
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.
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 🙂
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.
Harrison
Thanks for the info Harrison!
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?
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.
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
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.
Harrison
PS – I am definitely not a doctor.
And that’s science.
“In and out like a fucking sewing machine” hahahahahaha.
Excellent line, I’m having that!
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.
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!
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.
Thanks
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’:
http://www.bodybuilding.com/fun/jim-stoppani-six-week-shortcut-to-shred-nutrition-overview.html
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.
Harrison
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.
Thanks Kapsy 🙂
If you’re getting results – go for it!
Bear in mind, when used as stipulated this product is completely safe.
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.
Thanks
P.S Love your review going to put it on my FB page
Thanks Helen – I appreciate the share 🙂
Good luck with the gains – and let me know if you need any help/advice!

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.
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 🙂
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.
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.
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.
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.
Harrison
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?
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!

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?
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.
Hey Harrison, 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.
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.
Brilliant review… had me laughing in the morning when normally I go out and strangle anything that makes a noise.
Thanks Andy 🙂
Dear Harrison,
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.
I would take it before you hit the gym.
As I mention, it functions as a pretty neat little pre-workout supplement too!
Hi Harrison.
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.
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.

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.
Thanks
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.
Harrison
