  • 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


  • There are potential side effects associated with bitter orange peel – increased blood pressure and heart rate. Combined with other stimulants such as caffeine or green tea it can be potentially dangerous
  • 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

We’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 they are only text and no pictures, so there is no way of telling if these are genuine customer reviews or not.

Top 3 Fat Burners

Top 3 recommended fat burners


The ingredients list of this products is not as straight forward as you may think. The product is sold in the US as well as the UK and if you buy the US product this 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.

Grenade thermo detonator uk ingredients

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, an ingredient 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, 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 to aid losing weight. It is a thermogenic increasing metabolism, but research suggests that is also a natural appetite suppressant.

In addition to the four main ingredients it 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 contains a whole host of other ingredients. Also, the amounts are not visible on the label, hiding behind a proprietary blend.

Best and worst fat burner ingredients – 

Potential side effects

Due to the bitter orange peel 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.

Our Verdict

It is a cool looking product but look 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 product.

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, it is a negative of this product that it contains high amounts of bitter orange peel, a controversial, potentially dangerous thermogenic.

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 of what quantities of each ingredient are in this product.

Taking all the above into consideration we would give this fat burner 2.5 out of 5 stars.
