Nandrolone is an anabolic steroid that is derived from testosterone. It is commonly used in medical settings to treat conditions like anemia and muscle wasting diseases. Nandrolone promotes muscle growth and increases red blood cell production, which can enhance physical performance and recovery. In the world of sports and bodybuilding, nandrolone is often misused for its performance-enhancing effects. However, its use without medical supervision can lead to serious health risks, including hormonal imbalances and cardiovascular issues. Athletes caught using nandrolone may face penalties, including bans from competitions, due to its classification as a banned substance by organizations like the World Anti-Doping Agency.
