My buddy and I are thinking about taking some serious supplements. I'm 6'3 315 about 28-35% bf my friend is 6'6' 235 about 15%. I've taken DMZ and Stenavol and he's taken megadrol. We are thinking about taking injectables. What would be the best choice for young, first timers? He wants a lean bulking cycle and I want lean mass while cutting. We both also want to build athleticism.
