Anabolic steroids do have legitimate medical uses. They were first synthesized in the 1930s to treat underdeveloped testes and resulting testosterone deficiency. In the 1950s, they were used to treat anemia and muscle-wasting disorders and to bulk up patients whose muscles had atrophied from extended bed rest. In the 1960s, anabolic steroids were used to treat some forms of dwarfism. Today anabolic steroids are being studied for their ability to alleviate the extreme body wasting associated with acquired immunodeficiency syndrome (AIDS). Their most common use, however, remains among athletes seeking a quick competitive edge.
