This is completely incorrect and frankly your statement mirrors the problem. A "Bodybuilder" isn't only a professional (and even then your statement about substances is not grounded in fact). It can be anyone who is deeply interested in getting results out of their bodies. Most bodybuilders don't take steroids and other substances, they are just in tune with what makes their body build muscle and burn fat. I really suggest doing some research.
