I don't normally put up reviews but since I'm riding the craze wave right now I got motivation and energy out the **s. That being said holy ***K I read all the reviews and kept thinking it's gotta be overhyped, but bought into the hype like I usually do with supps. Took my first dose today @ 1.25 scoops. Took about 30min. to kick in and then the effects just became more and more intense. It compares to nothing I have used as a pre-workout before, good pumps, amazing vascularity, amazing endurance and motivation, and good focus. No jitteriness very clean and lasts forever. Don't take within I'd say 7hr. of bed. I would also say that if you've had depression issues or are on any meds for it don't take this stuff or at least start at 1/2 a scoop and work up. That's just from what I've read about it not personal experience. Only down side I can say would be taste and that I can only take it once a week since all my other workouts are in the evening/night and I know I won't sleep. It literally heads above all other pre-workouts I've tried examples: Jak3ed,NO xplode 1 &2, White Flood, Assault, Lit-up, superpump 250 and max, c4, and others. It's hard to put to words what the effects are like all I can say is try it and I bet you won't regret it. Hopefully it doesn't get banned or changed in the near future. I have already gotten 4 more tubs and if nutra or someone else does a deal I will stock up even more for sure.
