I took the liberty of looking the product up and found it contains 360mg of caffeine (and caffeine related stimulants) per dose. This is equivalent to approximately 6 large cups of strong coffee all at once. Dangerous stuff if you ask me. Frankly, I think all such magic fat loss crap, along with guarana "energy drinks" and their ilk should be heavily regulated, if not banned outright.

I don't claim to be impartial about this so I won't rant any further, but I but I don't see how that much caffeine could be healthy for anyone.
