Had a chance to try Poison. Let me say i have used Ephedrine/Caffiene, Hyperdrive and other energy/fat burner supps But Poison is by far the best ive tried. The mood elevation, appetite suppression are second to none. Puts you in a great mood all day and small meals feel like big meals. It has a nice kick to it making you very efficient. best thing is you only need 1 tablet and I have yet to expierence a crash. If your looking for a good quality fat burner then look no further.
