Steroids are synthetic substances similar to the male sex hormone testosterone. They are often used to improve athletic performance or physical appearance, but they can have serious side effects. Avoiding steroids is important for maintaining good health.
Steroid use can lead to a variety of health problems, including acne, high blood pressure, liver damage, and heart disease. Steroids can also cause psychological problems, such as aggression, irritability, and mood swings. In some cases, steroid use can even be fatal.
