I'm excited for his Levrone Formula to hit the market! Like Lucian said, I've tried it, and really did notice a difference in my workouts. I only take half the recommended serving since I'm just a lil thing. I don't really notice it "kicking in" like some pre-workout supps; I just really start to focus and am able to push through my training with a higher intensity. And there's no sudden drop in energy, or any sort of "crash" when it starts to wear off.
