my friend recently went to GNC and spent 80 bucks on gakkic (or something similarly spelled) its supposed to add 10% strength in 1 month of use. i was wondering what you guys think about this? is this possible (i think he wasted his money) he's had the stuff a few weeks now and he still hasn't used it. idk what he's waiting for.
