(an´´ua-bol´ik ster´oidz) Steroids with androgenlike stimulatory effects on protein synthesis. anabolism

A group of ergogenic aids (related to the male hormone testosterone) that have an anabolic (protein building) effect, and to a greater or lesser extent an androgenic (development of male characteristics) effect on the body.

Anabolic steroids are a type of performance enhancing drug that contains androgen. Androgen promotes tissue growth by stimulating protein synthesis.

Any of a group of synthetic derivatives of testosterone, having pronounced anabolic properties and relatively weak androgenic properties, that are used mainly to promote growth and repair body tissues. (12 Dec 1998)

Steroids that promote tissue growth by creating protein in an attempt to enhance muscle growth. The main anabolic steroid is testosterone (male sex hormone).
