1. ANABOLIC STEROIDS

Anabolic steroids can be used as performance-enhancing drugs that increase muscle mass and decrease fat, as well as causing many undesirable effects. Some athletes, weightlifters and bodybuilders take them regularly to improve their physical performance and build up their bodies.

They use them to boost muscle mass, performance, and endurance and to shorten recovery time between workouts. ... Anabolic steroids, also called anabolic-androgenic steroids (AASs), can build muscle and improve athletic performance, but they can also have significant adverse effects, especially when used incorrectly.
