A dangerous performance boost
Anabolic steroid misuse is a hot topic in professional sport and bodybuilding. These drugs mimic testosterone, which speeds up muscle growth, bone growth and red blood cell production. They can enhance sporting performance, but taking them carries many health risks. Anabolic steroids can increase the risk of high blood pressure, heart attacks and tumours in the liver and kidneys. In men, they can reduce sperm count, shrink the testicles and cause erectile dysfunction. In women, they can lead to excess hair growth, irregular periods and changes to the breasts and genitals. They are addictive, and they can cause serious changes in mood. In the UK, anabolic steroids are a class C drug; it’s not illegal to have them for personal use, but it is illegal to supply or sell them. Many professional sports associations ban their use because they put athletes in danger.
