Anabolic steroids are substances similar to the male hormone testosterone. They are used to promote masculine features, increase growth, build muscle tissue, and strengthen bones. Common anabolic steroid medicines include fluoxymesterone and nandrolone. All anabolic steroids available in the United States require a prescription and are used to treat conditions that occur when the body produces abnormally low amounts of testosterone, such as delayed puberty and some types of impotence.
Some people take legal dietary supplements that have certain steroid hormones also made by the human body. One such drug is dehydroepiandrosterone (DHEA). The body can turn DHEA into other steroid hormones, including testosterone, estrogen, and cortisol. People use it to try to make their muscles bigger. Whether such products actually work has not been proved. But if you take them in large amounts, they can cause the same side effects as anabolic steroids.
When anabolic steroids are taken without a medical reason, it is usually to improve performance in sports or to increase muscle size and reduce body fat. Some teens abuse steroids along with other drugs.
When these medicines are taken to supplement physical development, the dose is 10 to 100 times higher than when they are taken for medical conditions. They may be taken as a pill, an injection into a muscle, or a gel or cream rubbed on the skin. Often more than one of these drugs is used at the same time (stacking), or the drug is taken in a cycle from no drug to a high dose over a period of weeks to months (pyramiding).
Anabolic steroid use can cause a wide range of side effects affecting many systems in the body. Some of these effects can be permanent. Systems affected include the:
Hormonal system. In men, anabolic steroids reduce sperm count, shrink testicles, cause male-pattern balding, and enlarge breasts. In women, they cause masculine effects, such as decreased breast size and body fat, enlarged clitoris, and a deeper voice.
Musculoskeletal system (muscles and bones). A teen who abuses anabolic steroids may not reach his or her full adult height, because these drugs can stop bone growth before it is complete.
Cardiovascular system (heart and blood vessels). Some anabolic steroids affect the level of fat (lipids) in the blood and may cause a heart attack or stroke, even in a very young person. Anabolic steroids also increase blood pressure.
Liver. Anabolic steroids can cause liver cancer.
Skin. Anabolic steroids cause oily skin and acne. Skin infections can occur if the person injects steroids. And an infection can become severe if the drug was contaminated with a virus or bacteria during its preparation.
Brain. Anabolic steroids may cause irritability, homicidal rage, uncontrollable activity level (mania), or false beliefs (delusions).
