The vast majority of competitive bodybuilders are on very high doses of anabolic steroids (AAS) and compete in an "open" (untested) league. Absurdly high dose

The vast majority of competitive bodybuilders are on very high doses of anabolic steroids (AAS) and compete in an "open" (untested) league. Absurdly high dose AAS use is associated with (at least) a couple kinds of heart disease. It's not good for you. (There are also some "natural" bodybuilders and a smaller tested/natural league.)
