The potential side effects of anabolic steroids can be severe and include hormonal imbalances, such as increased testosterone leading to gynecomastia in men. Other side effects are liver damage, cardiovascular issues, mood swings, and behavioral changes. In women, anabolic steroids can cause facial hair growth, voice deepening, and menstrual irregularities.
