Anabolic steroids are not the same as the steroids used for treating illnesses such as asthma and autoimmune diseases such as Lupus, Crohn's disease and rheumatoid arthritis.

Those are corticosteroids.

Anabolic steroids, on the other hand, are synthetic forms of testosterone altered to amplify their potency. They're a kind of "super testosterone" -- a bionic hormone that was altered by scientists to work "better."
