Why are anabolic steroids banned?

Because of abuses: One of the public forces that drove govt to "ban" Anabolic steroids was high-profile athletes, some of who 'professed' never to have used them, were proven to be 'guilty'. Soit was 'secret', 'illicit' +not above board. Much use was 'amateur' and not managed by competent physicians. Doctors in general were either negative, uninformed of legitimate usage, or both. The media had a profit heyday.

Bad health: They cause serious poor health issues as shrunken testicles, enlarged prostate, breast development, erectile dysfunction, reduced sperm count, severe acne, high blood pressure and strokes http://www.health-today.org/wp-content/uploads/2011/08/sz1.gif
