Anabolic steroids are hormones that promote muscle growth and increase strength and energy.
Anabolic steroids can also have many side effects, including psychologic (mood swings, aggressive behavior, irritability) and physical (acne, masculinizing effects in women, breast enlargement in men).
These substances can be detected in urine for up to 6 months.
Treatment involves stopping use.

Anabolic steroids include the hormone testosterone and related drugs. Anabolic steroids have many physical effects, including promoting muscle growth and increasing strength and energy. Thus, these drugs are often used illegitimately to gain a competitive edge in sports. Users are often athletes, typically football players, wrestlers, bodybuilders, or weight lifters, and most users are male.
Anabolic steroids are used medically to treat low testosterone levels (hypogonadism Effects of Aging on the Male Reproductive System It is not clear whether aging itself or the disorders associated with aging cause the gradual changes that occur in men's sexual functioning.

The drugs may be taken by mouth, injected into a muscle, or applied to skin as a gel or in a patch.
Athletes may take steroids for a certain period, stop, then start again several times a year. This process is called cycling. Athletes also often use many steroids at the same time (a practice called stacking), and they take them by different routes (by mouth, injection, or patch). They may also increase the dose through a cycle (called pyramiding). Pyramiding may result in very high doses. Cycling, stacking, and pyramiding are intended to enhance desired effects and minimize harmful effects, but little evidence supports these benefits.
At doses used to treat disorders, anabolic steroids cause few problems. However, athletes may take doses 10 to 50 times these doses.
Symptoms and Signs of Anabolic Steroid Use
Anabolic steroids have physical and psychologic effects. The more drug is taken, the greater the effect.
The main physical effect of anabolic steroids is
Increased muscle size
Other physical effects include

Virilization (masculinizing effects) in women, such as baldness, excess body hair (hirsutism Hairiness In men, the amount of body hair varies greatly (see also Overview of Hair Growth), but very few men are concerned enough about excess hair to see a doctor.

Gynecomastia in men and masculinizing effects in women may be irreversible.
Increased acne is common in both sexes. Libido may increase or, less commonly, decrease. Aggressiveness and appetite may increase. In younger adolescents, steroids can interfere with the development of arm and leg bones.
Long-term use can cause the body to produce too many red blood cells and abnormal levels of fats (lipids Overview of Cholesterol and Lipid Disorders The body needs fats for growth and energy.

Steroids have several psychologic effects (usually only with high doses):
Wide and erratic mood swings
Increased aggressiveness (steroid, or "roid" rage)
Increased sex drive (libido) in men and sometimes in women
Diagnosis of Anabolic Steroid Use
Urine tests are done to check for breakdown products of anabolic steroids. These products can be detected up to 6 months after use is stopped.
Prevention of Anabolic Steroid Use
Adolescents and young adults should be taught about the risks of taking anabolic steroids starting in middle school. Also, programs that teach alternative, healthy ways to increase muscle size and improve performance may be useful. Such programs emphasize good nutrition and weight training techniques.
Treatment of Anabolic Steroid Use
Stopping use of steroids
The main treatment is stopping use. Although physical dependence does not occur, psychologic dependence, particularly in competitive bodybuilders, may exist.
