Abstract Anabolic androgenic steroids (AAS) are misused to a high extent in sports by athletes to improve their physical performance. Sports federations consider the use of these drugs in sports as doping. The misuse of AAS is controlled by detection of the parent AAS (when excreted into urine) and (or) their metabolites in urine of athletes. I present a review of the metabolism of AAS. Testosterone is the principal androgenic steroid and its metabolism is compared with that of AAS. The review is divided into two parts: the general metabolism of AAS, which is separated into phase I and phase II metabolism and includes a systematic discussion of metabolic changes in the steroid molecule according to the regions (A-D rings), and the specific metabolism of AAS, which presents the metabolism of 26 AAS in humans.

An estimated 293,000 people living in the United Kingdom have used anabolic-androgenic steroids. However, there is currently no intervention to reduce usage available in practice or academic circulation throughout the United Kingdom. This study aimed to test a novel hypothesis that increased levels of intrasexual competition may play an important influential role in the use of anabolic-androgenic steroids. Significantly higher levels of intrasexual competition were evident in users compared to non-users but only in the novice group (0–2 years of experience). The research provides evidence for intrasexual competition potentially influencing anabolic-androgenic steroid use but only during the initial stages of usage.
