yep exactly right, ppl on roids will have bad rashes on there backs if u look closely they are actually pimple rashes. i take a mega creatine, which does not need a loading stage, and i also take tribulus which naturally increases testosterone levels, and to tell you the truth i havent had any problems with pimples. if anything, because i am drinking alot more water for the creatine supplement, my face is perfectly clear now.
