Commentary- Increasing abuse of anabolic steroids and chemsex drugs as performance and image-enhancing agents

Anabolic Androgenic Steroids (AAS) are a family of synthetic “Appearance and Performance Enhancing Drugs” (APED) derived from natural sex hormones, such as testosterone and its derivatives or precursors (e.g., dihydrotestosterone)1 . Whereas testosterone is the androgen responsible for the development of male secondary sex characteristics and elicits both anabolic and androgenic effects, AAS mostly simulate the anabolic effect of endogenous testosterone, and induce only partial androgenic effects2 . In the 1930s, anabolic steroids were shown to facilitate muscular growthhand consequently became rapidly popular among bodybuilders and other athletes, and were already widespread in the 1960s. AAS have been and still are among the doping agents most frequently misused by athletes, regardless of the type of sport, both in preparations containing natural anabolic drugs [e.g., testosterone and dehydroepiandrosterone (DHEA)] and in those with synthetic substances (e.g., dianazole, nandrolone, stanozolol and tetrahydrogestrinone
