Grenade is a company selling a number of different sports supplements. They have been around since 2009 and their product range has grown year on year.

They also have a stimulant free version of this product.

You can read my review to see what I’ve found about Grenade Thermo Detonator fat burner.


  • High levels of green tea – there’s plenty of research supporting the effectiveness of this ingredient when it comes to weight loss
  • Available to buy on a number of different websites, not only on the company’s website
  • Double action formula – both suppressing appetite and increasing metabolism
  • The UK product has no proprietary blend – all the ingredients and their amounts are clearly visible


  • Contains bitter orange powder – associated with negative side effects such as increased blood pressure and heart rate.
  • High levels of caffeine
  • Completely different formulas for the same product sold in the UK and in the US – very confusing
  • The US formula contains a lot of additional ingredients and the amounts are not stated – hidden behind a proprietary blend

Grenade thermo detonator Amazon Review


I’ve not found any genuine customer testimonials on Youtube only some videos from people selling the product. There doesn’t seem to be much noise on social media either other than on the posts of the company or other sellers.

There are some customer testimonials on the company’s website, but there are no photos with the written testimonials. So there is no way of telling if these are genuine customer reviews or not.

Dosage – How to take Grenade Thermo Detonator fat burner

There are a number of different bottle sizes to purchase on the company’s website. The largest bottle contains 100 capsules which would last for 25 days with the 4-a-day dose.

The company’s website recommends taking 2 capsules on an empty stomach upon waking with water then take a further 2 capsules 30 minutes prior to lunch with water. They also warn that you should not exceed a maximum of 4 capsules per day.

Top 3 recommended fat burners


The ingredients list of Grenade Thermo Detonator fat burner is not as straight forward as you may think. The product is sold in the US as well as the UK. If you buy the US product, it will have a completely different formula to the UK product sold under the exact same name.

The ingredients in the US product are conveniently hidden behind a proprietary blend with no ingredient amounts disclosed. On the other hand the main ingredients in the UK formula are clearly marked on the label.

The UK formula contains the below ingredients. The amounts are per 2 capsules, so the daily serving would be twice the amount.

Green Tea

The first main ingredient of this product is green tea and it contains a large dose of this natural fat burner. There is plenty of research backing the effectiveness of green tea as a natural fat burner. It contains polyphenols that increase the body’s metabolism and therefore increasing the rate at which the body turns food into energy.

Bitter Orange Powder

The second main ingredient of the Grenade Thermo Detonator fat burner is bitter orange powder. Although it is a natural ingredient, it contains synephrine and octopamine, compounds which have similar effects to that of ephedra. Ephedra has been previously banned by the FDA due to the related health risks. Bitter orange can raise blood pressure and speed up heart rate.


Caffeine, the third main ingredient of this product is another natural thermogenic ingredient that helps to increases catecholamine level in the blood. These chemicals are responsible for mobilising the fat stores enabling the body to burn more fat. Caffeine also gives the body an energy boost you need before workouts so you can go harder in the gym.

Cayenne Pepper

Last but not least, the fourth main ingredient of the Grenade Thermo Detonator fat burner is cayenne. Cayenne peppers are high in antioxidants and are rich in capsaicin which is the key compound when it comes to weight loss. Capsaicin acts in two ways when it comes to weight loss. It is a thermogenic increasing metabolism. However, research suggests that it is also a natural appetite suppressant.

In addition to the four main ingredients the UK formula also contains a small dose of green coffee (10mg per 2 capsules) and phenylalanine (25mg per 2 capsules) and some additional compounds such as magnesium stearate and titanium dioxide.

The product is available in the US under the exact same name. However, the US product contains a whole host of other ingredients. Also, the amounts are not visible on the label, hiding behind a proprietary blend.

Potential side effects of Grenade Thermo Detonator fat burner

Due to the bitter orange powder content of this product, it has potential side effects such as increased blood pressure and elevated heart rate. People taking bitter orange combined with other stimulants such as caffeine have reported stroke and heart attack.

People may also experience side effects due to the high caffeine content of the product. So if you are sensitive or allergic to caffeine, this product may not be for you. If so, they also have a stim free version of Grenade Thermo Detonator.

Final Verdict on Grenade Thermo Detonator fat burner

It is a cool looking product but I’ve looked beyond the marketing. What’s in the product is what really matters. This fat burner has some good and proven thermogenics such as green tea, caffeine and cayenne. The doses are quite high as well for effectiveness which you would expect from a premium priced fat burner.

The cayenne in the product also acts as a natural appetite suppressant. However, there are more effective natural appetite suppressants out there such as glucomannan.

However, one downside of Grenade Thermo Detonator fat burner is that it contains high amounts of bitter orange peel. As it is a controversial and potentially harmful thermogenic, I’d definitely avoid products containing it.

The mixed customer reviews and the lack of people talking about taking the product on social media are also leaving some questions about this product unanswered.

In addition to this, it is concerning that the product is sold under the same name in the USA and the UK, but has completely different ingredients. Not only that, but the US formula also hides behind a proprietary blend leaving you guessing what quantities of each ingredient are in this product.

Taking all the above into consideration I would give this fat burner 2 out of 5 stars.
