Hard work, diet, and genetics.

Very few guys can get that big without 'roids.

A body builder friend with a natural mesomorph physique had to eat massive amounts of food, and was always working out. He said he could tell who the guys at the gym were that were taking steroids by casually commenting to them "I hear steroids shrink your junk". He said the guys that were on them would always reply, "No, it makes it bigger". My friend claimed this technique for detecting steroid use was at least as accurate as a piss test.
