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.
Anabolic steroids have physical and psychologic effects. The more drug is taken, the greater the effect.
