Anabolic-androgenic steroids (AAS) are widely abused, but the potential for dependence and addiction remains unclear. Recent studies from our laboratory have shown that male and female hamsters will voluntarily self-administer testosterone and other AAS. Furthermore, we have observed fatal androgen overdose during self-administration. This suggests that AAS are potentially addictive, independent of their effects on muscle mass or athletic performance.
