Product Overview

Declare war on fat

Grenade® is rapidly being recognized as the World’s fastest growing weight loss brand, with sales in over 130 countries. The multi award winning** Grenade® Thermo Detonator® is suitable for men and women and is extensively used by professional athletes, fitness enthusiasts, military personnel and Special Forces worldwide.

Grenade® Thermo Detonator® contains key ingredients clinically suggested to help burn fat and support weight loss.* The advanced thermogenic formula is highly effective prior to intense cardio and DTP sessions.

Grenade® Thermo Detonator® is a fat-loss product that combines scientifically researched ingredients designed to target body fat and preserve maximum lean muscle. It’s obvious, you want to keep all of your hard-earned muscle, while improving your energy and performance while blasting away the excess fat! That is exactly the philosophy behind Grenade® Thermo Detonator®, to ‘Declare War on Fat’, not muscle!*

Thermo Detonator® combines only the highest quality, maximum strength ingredients designed to ‘ramp up’ your metabolic rate and decrease your appetite without causing the jitters. It delivers a sustained release of energy and alertness, with less chance of a ‘come down’ or ’crash’ at the end. Rest assured that in the formulation of Thermo Detonator®, only the most effective ingredients have been used. Most people who’ve been around the block know that to lose fat you have to deliver the correct signals to stimulate the hormone norepinephrine (among others), which is believed to be the body’s most important hormone in support of fat oxidation (using fat for energy). You also have to target specific parts of the brain to combat hunger. Thermo Detonator® is designed to do both concurrently, while delivering improved mental and physical performance but without any nasty side effects.*

So, if you want the most powerful dosages of the most effective fat loss ingredients along with a steady stream of energy and alertness but you also want to hang onto your hard-earned muscle, no product declares war on fat like Grenade® Thermo Detonator®.

**FATBURNER OF THE YEAR 2013, 2014 (UK supplement awards)
PRODUCT OF THE YEAR 2013, 2014 & 2015

Green Tea Extract

(80% polyphenols, 45% epigallocatechin gallate, epicatechin)

Green tea, despite its modest name, contains certain active polyphenols that have been scientifically-demonstrated to have significant physiological effects, including fat loss, performance support and antioxidant effects.* Of particular interest is the catechin compound “epigallocatechin gallate”, which has been extensively investigated in several scientific studies and may be an important, natural molecule in the war on fat!* The specific green tea material used in Grenade® Thermo Detonator has been manufactured to optimize levels of this compound.*

Bitter Orange Extract

(synephrine, octopamine, N-methyltyramine, tyramine, hordenine)

This ingredient is another custom-processed extract also known as citrus aurantium. Its principal active extract is synephrine, which is a sypathomimetic, meaning that it stimulates the hormones involved in mobilizing and oxidizing (burning) energy and it has been specifically suggested to enhance lipolysis (fat breakdown).* N-methyltyramine and tyramine have the ability to release catecholamines, which are the most powerful fat burning hormones in the human body. Octopamine is the N-methylated analogue of synephrine and it also has the ability to stimulate fat breakdown.*

Caffeine Anhydrous

(1,3,7 - trimethylxanthine)

Caffeine Anhydrous is a xanthine alkaloid that is well known in the scientific literature to mobilize fat from fatty tissue and to increase physical performance and mental focus.

Grapefruit Seed Extract

(6,7 - dihydroxybergamottin)

The extract of grapefruit seed, dihydroxybergamottin, is known to prolong the effects of various compounds involved in the fat-burning process.

Capsicum Annuum


Prominent weight loss scientists have investigated the considerable research on capsaicin-containing natural ingredients and suggest that they can both increase energy expenditure and fat oxidation (fat burning) so as to decrease the energy balance equation.* This would of course be expected to reduce body fat levels.*


(evodia fructus extract)

The scientific literature describes evodia fruit as a “hot nature” herb. Evodiamine is currently undergoing intensive investigation for its “thermogenic”, appetite-suppressing and weight loss effects that have already been suggested in the rodent model.* These effects suggest increased fat and calorie burning along with decreased food cravings.*

Yohimbe Bark Extract


Traditionally used to support sexual health, yohimbine is suggested to increase the mobilization of fat and the secretion of fat-metabolising hormones in healthy men.* Yohimbine appears to deliver its effects via blockade of the alpha-2 adrenoreceptor, which prolongs the metabolism of norepinephrine – one of the body’s most powerful fat-burning hormone.*

Raspberry Ketones

[4-(4-hydroxyphenyl) butan11px-one]

Raspberry ketones work much like capsaicin and evodia and they are also being studied for their ability to resist fat gains in rodents fed high-fat diets.*


(2-amino-3-phenylpropanoic acid)

This amino acid may help to elevate levels of the appetite-suppressing hormone cholecystokinin (a.k.a. CCK) and may promote better mood and attention levels.*

Cocoa Bean Extract

(methylxanthines, flavanols)

In addition to supporting good blood flow and its antioxidant effects, it has been suggested that cocoa flavanols may support parameters associated with insulin function and healthy body composition.*

B-phenethylamine HCl


Phenethylamine is directly involved in the release of not only norepinephrine (which has already been discussed for its fat-burning effects) but also dopamine. Higher dopamine levels may support mood and concentration.*

Coleus Forskohlii


Forskolin has a direct influence on adenylate cyclase, this enzyme activates a second messenger called cAMP, which promotes the breakdown of fat in fat cells. This has been demonstrated in both humans and animals. It has also been suggested to reduce body fat gains in adult humans.*

Yerba Mate Leaf

caffeine, theobromine and theophylline)

This is a favourite energy drink of many South Americans who consume it much like coffee. It has naturally high levels of xanthine stimulants that may increase metabolic rate and have other common stimulant effects.



This organic molecule is best known for its effects on alertness and mood and it may fuel neurotransmitter production in the body.*

It really worked for me,i was running for 17 minutes every other day for one year but only after use of grenade i got in shape in a month . I just took two pills pre-workout and i didnt feel anything like pain in stomach but my friend felt irritation right after taking em

I'm very sensitive to all the thermogenic products, so I definitely can never take this at full dose. I work up to 2 in the morning, 1 just before lunch and 1 just after lunch. Definitely a little crack-like when re-starting to take if I've been up for a while, but give a sustained energy boost once I'm acclimated. I definitely notice 3-5 lbs weight loss over the 8 week cycle I do.

Sep 02, 2018

Updated review on this. For me it can't be used as a replacement for a pre workout. Makes me feel nautilus and gives heartburn. I've an extremely high tolerance to caffeine so I know it's not that. Not the same energy levels as a pre either, nowhere close. Also can't really be used on conjunction with a pre workout as there would be too much caffeine if you like stim pre workouts. A good pre workout a solid workout and a good diet has lost the weight for me so far. I regret buying this as it's thrown off my routine. Hasn't worked for me anyway. Definitely heats you up, but so does rigorous exercise so I won't be buying any fat burners again.

I tried other fat burners but I came back to this one. Out of the fat burners I've tried the grenade works the best.

Comparing this product to thermabol it's hands down the winner. With diet and workouts combined with this i lost 5% of body fat without losing weight. Great product!

I did lose a 4 or 5 pounds. Gives a tremendous boost as like a pre-workout. And I never felt hungry while on it. There was so much energy I didn't even take coffee in the morning. No crashes. It works. But follow the serving suggestions. Jacks your stomach up. It took me a little over a week of taking 1 pill at a time before I was able to increase it to 2 pills at a time.

So, first week I wasn’t sure about starting on half dose - I quickly learned you probably should follow that instruction - taken without attention these can mess with your stomach a bit - I also consume a fair amount of coffee whilst on these and have no negative side effects. Warnings aside, I think they’re great, probably get about a 25% boost in stamina when training compared week to week.

Feb 16, 2018

Gives you the energy you need, I saw that I was more focused, curbed my appetite and I lost 29 lbs in 2 months combined with healthy diet and workout plan. Only thing I have to say is when your not on it your mood isn’t the same and feel kind of tired thru the day. Other than that def recommend this product !

This was the first fat burner used before trying other brands. So I writing the review after I have used another one to compare. The results when using Thermo Detonator were more visible, didnt give me late afternoon crashes. I was able to keep my sleeping pattern without any issues. I'm still using the competitors fat burner since I order a large quantity. However, I do have the intend to go back to Thermo Detonator after all I have left is gone.

Is a very strong and effective product. Only complaint is that it is not for the weak stomach people. I usually can handle stuff pretty well, but this stuff just tears my stomach up. Also have had problems with belching constantly when I take it. If you can get past this part, I have had great results using it.

This is such a great fat burner I don't think people really understand how effective this can be. I am a professional dancer and while rehearsing for a show I took these in an effort to burn fat and achieve abs for the first time in my life! With a goodish diet, quite a lot of cardio and a whole lot of core exercises, I saw a massive difference in FOUR WEEKS! I have pictures to prove it. That was the beginning of my fitness journey when I didn't even really know what I was doing. A couple times I gained weight again, due to life etc Then lost it all in a matter of weeks with intense workout. This also works great as a pre-workout. The one side effect which got me for a couple days, is it caused a slight insomnia :-/. I don't even drink coffee so having such a highly concentrated dose of caffeine did mess with my sleep patterns a little.

I have tried fat burners along my bodybuilding career. I have tried Hydroxicut, Xenadrine, GAT Superfuel and many others. This Grenade Fat burner I can say it's good, it does give you a kick in the morning when I most need it. I mainly use it instead of the 3 cups of coffee, I used to had in the morning. It does gives you a good focus and doesn't give you the annoying jitters. One good pro is that it doesn't destroy my stomach like other fat burners used to do. I only take 1 capsule per serving since there is no specific quantity of caffeine per capsule, so I guess, if I would take 2 capsules per serving it would be different. I would recommend it, however not for beginners.

Truthfully I originally ordered this product for the gernade containers ! I do take fat burners so I can eat as I wish . I have a few that are my daily drinks etc. first thing I found with these was that they are really strong and I had to adjust when I took them One with my pre and my stacks and another a few hours later after I had my lunch .. if your new to supplements then be careful of caffeine doses ... but is defently a product that will get you results
