Anabolic-androgenic steroids promote skeletal muscle growth and male sexual characteristics in females and males.
Some testosterone-related medicines also have legitimate medical uses, including treatment of certain hormone deficiencies, delayed puberty or muscle loss from disease. Prescribed medical treatment is not the same as misuse. In this context, misuse means non-prescribed use of testosterone or testosterone-like substances for appearance or performance purposes, rather than every instance in which a person receives a steroid-related medicine.
