I've tried Jacked, Mesomorph,1 MR, Creatine Nitrate PWO's among many more popular brands. Based on feedback and early reviews, and also my experience on Triazole, I decided to take a leap of faith and order Craze. I received it this evening for my first workout and I was blown away. It's only been one workout, but I was away from the gym for close to a month (sick), and I wasn't sure if the stim content of Craze would be enough to power me through. Not only was I blown away by the energy, which feels entirely different than anything I've experienced with 1,3, but I felt a mind muscle connection that I have never experienced before, while using any PWO. It's smooth and comfortable, and offers a laser like focus that is not comparable in other PWOs. Yes, I've experienced massive pumps with other preworkouts and crazy stimmed out energy which at the time, I thought was great,but never really translated into athletic performance outside of just the weight room, but now having tried Craze, I think I'm leaving 1,3 land behind forever as it relates to PWO's. The tunnel vision is that AMAZING. You feel locked into every movement and mood is off the charts and I've been sleeping horribly this past month. I'm telling you, do yourself a favor and request a sample or order it off blind faith, I all but guarantee you... you'll love it.
