the bodybuilding site seems pretty informative.....i started working out lightly about a year ago. i wanted to drop wieght. i went from 218lbs to 190lbs. im comfortable at this wieght but i want to grow in the chest,arm area and firm up my stomach. my ? is about supplements, i take none right now. the only thing i take are gnc mega mens vitamins. besides whey protien what should i drink? any other types of pills?
