I was starting to get away from the 2 amino pres because some of them were disappointing in that they just made me space out in the gym. I had version 2 of Legit and it was pretty solid. So I took a chance and was glad I did. This preworkout is awesome. It puts me in a zone where I lose track of time and I realize 2 hours have blown by. I feel great during the workout and the energy keeps going into my work day. Good positive vibes. Good energy. I would run this everyday if I could. Highly recommend.
