i bought supplements at first because i wanted to get "bigger" for football, and in teh old metrx days a lot of football players were endorsing their crap. it was weight gainer and creatine for me most of the time. then when that didn't work, i just switched to eating and creatine.
now i have 2 jugs of protein that i only start using about a month before they expire, and don't use any other supplements.
of course, i've always looked like shit.
