For teachers: Background information and classroom activities for use with the Anabolic Steroid Student Booklet.

Anabolic steroids are chemicals that are similar to the male sex hormone testosterone and are used by an increasing number of young people to enhance their muscle size. While anabolic steroids are quite successful at building muscle, they can damage many body organs, including the liver, kidneys, and heart. They may also trigger dependency in users, particularly when taken in the large doses that have been known to be used by many bodybuilders and athletes.
