I got a sample of this from nutraplanet with my last order. Took one cap upon waking at like 9 empty stomach like it says to access tolerance and let me tell u this stuff is serious within 15 minutes my hands were sort of shaking, I started to kind of lightly sweat, I felt like going for a run I swear I just wanted to bolt my ass out the door, it's 12:25 now I've had breakfast and am at work and can't stop pacing, but it's a really clean energy feeling I'm really impressed and plan on ordering a bottle.

Edit: I plan on using the second pill tomm instead of a pre workout for the gym. I wouldn't even dose more then 1 a day probably it's that strong
