when a bodybuilder,natural or drugged quits lifting every day he or she is going to shrink,the body has no reason to stay large cause theres no resistance being put on it.people always say it all drugs when guys r big but they still have to lift everyday and eat right,u think if a guy took roids and sat on the couch he will get musculer?it wont happen. what we see is a guy who stopped lifting,stopped using steroids,and stopped eating as many calories(protein) also,the end result is a smaller version of what he once was. roids do help alot PROVIDING u r training everyday and EATING ENOUGH also,but they aint the ALL IN ALL
