I am a student at Texas A&M Univ., and im about to start another Sust./Deca. cycle. I want to gain 20 lbs. (180-200), but i have a perscription to Adderall, which is an amphetamine that makes me concentrate and study and shit, but it also ups my metabolism and supresses my appetite. should i quit taking it or will it not effect me? Thanks for the info...peace![]()
