Scientists have attempted to test the association between anabolic steroids and aggression by administering high steroid doses or placebo for days or weeks to human volunteers and then asking the people to report on their behavioral symptoms. To date, four such studies have been conducted. In three, high steroid doses did produce greater feelings of irritability and aggression than did placebo, although the effects appear to be highly variable across individuals. In one study, the drugs did not have that effect. One possible explanation, according to the researchers, is that some but not all anabolic steroids increase irritability and aggression. Recent animal studies show an increase in aggression after steroid administration.
The gains made by athletes in uncontrolled observations have been much more impressive. Weight gains of thirty or forty pounds, coupled with thirty percent increases in strength, are not unusual. Such case studies lack credibility because of the absence of scientific controls. However, it would be foolish to completely disregard such observations because the "subjects" have been highly trained and motivated see the articles on pharmacology of sport and sports medicine in the countries of the former Soviet Union for more information on anabolic steroids.
Awareness and educational efforts are working to help prevent anabolic steroid abuse in schools and communities. The Adolescents Training and Learning to Avoid Steroids (ATLAS) and the Athletes Targeting Healthy Exercise and Nutrition Alternatives (ATHENA) programs, funded by the NIDA, and supported by the Oregon Health & Science University programs is teaching athletes that they do not need steroids to build powerful muscles and improve athletic performance. These programs provide weight-training and nutrition alternatives, increase healthy behaviors, less likelihood to try steroids, and less likelihood to engage in other dangerous behaviors such as drinking and driving, use of marijuana and alcohol , and and improved body image. Bother Congress and the Substance Abuse and Mental Health Services Administration endorsed these model prevention programs. 4
