Yeah ive heard HGH doent really help with preformance at all, it just helps with recovery time so you can work out sooner..... you got to be working out pretty extreme to justify using it. I have heard it cuts fat though. Too expensive if youre not a profesional in my mind. I would never do steriods, it seems like they can just mess you up to much.
I take creatine as my only regular supplement. I think it definitely helps me, but i fatten up a bit while on it. Ive taken L-Arginine a few times and didnt really notice anything. Ive also taken Jack3d, which gives you a uncomfortable amount of engery and definitely helps you do anything but sleep.
