Performance-enhancing drugs (PEDs) are substances used by athletes to improve their physical abilities, such as strength, speed, and endurance. These drugs can include anabolic steroids, stimulants, and hormones like erythropoietin (EPO). While they may provide short-term benefits, their use can lead to serious health risks and ethical concerns in sports. The use of PEDs is often banned in competitive sports, as it creates an uneven playing field and undermines the spirit of fair competition. Organizations like the World Anti-Doping Agency (WADA) enforce rules and conduct tests to deter athletes from using these substances and to promote clean sportsmanship.
