Anabolic steroids do not improve agility, skill or cardiovascular capacity. Some are visible to the naked eye and some are internal. Some are physical, others are psychological. Also, if anabolic steroids are injected, transmitting or contracting HIV and Hepatitis B through shared needle use is a very real concern.

Anabolic steroids can halt growth prematurely in adolescents.
Once these growth plates are closed, they cannot reopen so adolescents that take too many steroids may end up shorter than they should have been. According to Dr. Wadler, anabolic steroids can cause severe mood swings. This is a dangerous state beyond mere assertiveness. Recent evidence suggests that long-time steroid users and steroid abusers may experience the classic characteristics of addiction including cravings, difficulty in stopping steroid use and withdrawal symptoms. Regardless, there is no question that when regular steroid users stop taking the drug they get withdrawal pains and if they start up again the pain goes away.
