Prob the best pre workout supp i've ever taken. it literally makes me more aggressive, and i dont run out of energy while training. its probably the only good product usp makes. I tried the Prime, anabolic pump and powerfull stack and it sucked. I had blood work done a month after completing that stack and my test levels were in the basement and my liver enzymes were slightly elevated. non hormonal my ass... but Jacked works really well
