I brought 6 cans to get a cheaper price. I'm still taking it although it didn't have major impact, but i think it helps..somewhat. however, I peronsally know people swear by it. (p.s. I'm 90% cured after 5 years of trial and error to find the perfect combination of exercise, diet, and supplement.
I'll suggest you to buy a can from raider at this formn or from ebay to try it out. It CAN be your silver bullet like they claim, but it doesn't work great on everyone.
