"Anabolic steroids" is the familiar name for synthetic substances related to the male sex hormones (., testosterone). They promote the growth of skeletal muscle (anabolic effects) and the development of male sexual characteristics (androgenic effects) in both males and females. One of the main reasons people buy steroids is to improve their athletic performance. Another reason people go to find steroids for sale online is to increase their muscle size or to reduce their body fat. Some people who purchase steroids to boost muscle size are experiencing physical or sexual abuse - being bigger and stronger would discourage further attacks.
