Grenade Thermo Detonator
A thermogenic 'fat-burner' sold as capsules rather than a powder — its formula combines caffeine (around 200 mg per two-capsule serving) with green tea extract, bitter orange and cayenne. Unusually for this category, it's Informed Sport certified, so every batch is screened against the banned-substances list. £24.94 at Amazon UK (6,400 reviews) and £35.00 at Holland & Barrett.

Why this certification matters
- Informed Sport
- Informed Sport certification is especially relevant for athletes in tested sports because products are batch-tested for substances prohibited in sport.
Frequently asked questions
- How much caffeine does it contain?
- Around 200 mg per two-capsule serving — comparable to two cups of coffee — alongside green tea extract, bitter orange and cayenne. Avoid taking it late in the day or stacking it with other caffeine sources.
- Why is a fat-burner Informed Sport certified?
- Informed Sport batch-tests against the WADA banned-substances list. Fat-burners and pre-workouts are a common contamination risk for tested athletes, so certification is reassuring here in a way it isn't for most thermogenics.
- Is it a capsule or a powder?
- Capsules — convenient to take without mixing a drink. It's taken in servings of two capsules; check the label for the daily limit.
- Why is Holland & Barrett more expensive than Amazon?
- The two listings — £24.94 at Amazon UK versus £35.00 at H&B — may differ in pack size and seller. Check the capsule count before comparing, and note the Amazon listing has far more reviews.
- Do thermogenic fat-burners actually work?
- Ingredients like caffeine and green tea can modestly raise energy expenditure, but they aren't a substitute for a calorie deficit and exercise. Treat any fat-burner as a minor adjunct, not the main driver of fat loss.
