Anabolic androgenic steroids are synthetic derivatives of the male hormone testosterone that are taken to build muscle, enhance performance, and improve appearance. The drug’s anabolic or “muscle-building” effects help the body retain protein, a necessary building block for the growth of muscles, bones, and skin. The androgenic or “masculinizing” effects cause the development of a deep voice, facial and body hair, muscle mass, and aggressiveness. Unfortunately, steroid abusers risk a variety of unwanted side effects, some of which are irreversible. Another significant danger includes HIV infection if needles are shared.
