Testosterone is responsible for both promoting and maintaining muscle growth, and for the development of secondary male sex characteristics such as deepening voice and facial hair.
Also called anabolic-androgenic steroids AAS , these drugs have a unique ability to enhance muscle mass. Long-term, non-medical uses are associated with adverse effects, including heart problems and aggression.
Here are some key points about anabolic steroids. More detail and supporting information is in the main article. Anabolic-androgenic steroids are synthetic versions of the primary male hormone, testosterone. They produce their effects in many parts of the body, including the muscles, bones, hair follicles, liver, kidneys, blood, immune system, reproductive system and the central nervous system.
During puberty , increases in testosterone levels are responsible for the development of male characteristics such as beard and body hair growth, linear growth height , deepening voice, sex drive and muscle mass accumulation.
Testosterone also promotes the laying down of bone mineral and can contribute to competitiveness, self-esteem and aggressiveness. Anabolic steroids can be taken orally, through injections or transdermal delivery creams or gels applied directly to the skin. Once ingested, anabolic steroids travel through the bloodstream to the muscle tissue where they bind to an androgen receptor. The drug can subsequently interact with the cell's DNA and stimulate the protein synthesis process that promotes cell growth.
For non-medical purposes, anabolic steroids are typically taken in cycles of about weeks the on period followed by 4 weeks to several months off. This cyclical pattern is an attempt to reduce the likelihood of undesirable effects.
Despite the risk, however, some bodybuilders will take AAS almost continuously. Continuous use of AAS can lead to tolerance and may even cause the body to stop producing its own testosterone.
In addition, users often combine several different types of steroids or incorporate other supplements stacking in an attempt to maximize the effectiveness of the steroids.
The legal status of these medications varies from country to country. In the US, AAS is a schedule III controlled substance available only by prescription, and their use is only legal when prescribed by a medical provider. Medical conditions primarily male treated using AAS include anemia , wounds, malnutrition , delayed onset of puberty, osteoporosis and hypogonadism.
Testosterone and several of its esters, as well as methyltestosterone, nandrolone decanoate and oxandrolone, are the main anabolic-androgenic steroids currently prescribed in the US.

Most athletes consume AAS on a trial-and-error basis using information gained from other athletes, coaches, websites or gym "gurus. The prevalence of anabolic steroid use in adults is estimated to be in the hundreds of thousands.
Most users are men involved in weightlifting, bodybuilding and professional sports, but use among women and adolescents is also on the rise. Illegal steroids are obtained from black market sources and trade, and can be purchased through dealers just as any other illegal drug is obtained.
The Internet is the most widely used means of buying and selling anabolic steroids. However, there is also evidence of diversion through unscrupulous pharmacists, doctors and veterinarians. The adverse effects associated with anabolic-androgenic steroids are dependent on the age and sex of the user, the amount used and the duration of use.
Typical side effects of legally prescribed normal-dose anabolic steroids may include acne , fluid retention , gynecomastia enlarged male breasts , increased red cell count and changes in cholesterol levels. Users should follow up with their prescribing clinician and take periodic blood tests to monitor for these effects. Studies of men taking physiological doses of AAS medications found no changes in aggressive behavior.
Additional side effects include hair growth, hair loss , infertility , changes in libido, decreases in HDL-cholesterol "good" cholesterol and increases in LDL-cholesterol "bad" cholesterol. In adolescents, use of anabolic steroids can permanently stunt growth.
In women, use of the drugs can induce permanent physical changes including deepening of the voice, increased facial and body hair growth and the lengthening of the clitoris. In men, use of AAS can cause shrinkage of the testicles, enlargement of the male breast tissue and sterility. Anabolic steroid use can damage the liver and can cause an increase in cholesterol levels.

Female abusers could experience body and facial hair growth, male-pattern baldness, changes in the menstrual cycle, shrinking breasts, increased sex drive, acne and a deepening voice. Some of these changes are permanent, even when the anabolic steroids are stopped. Abusers who inject their steroids run the added risk of contracting or transmitting blood-borne infectious diseases such as HIV or Hepatitis via shared needles. Finally, chronic AAS users can also experience psychiatric symptoms such as severe mood swings, paranoia, delusions, impaired judgment, feelings of invincibility, mania and anger "roid rage" that may lead to violence.
These extreme unwanted effects are more likely to be seen in those who have a predisposition to these types of behaviors. There is no evidence in the available literature that legitimate medical use of AAS leads to abuse or dependence.
However, long-term AAS abuse can affect some of the same brain pathways and chemicals that are affected by other drugs such as opiates, resulting in dependency and even addiction. Individuals who abuse anabolic steroids can experience withdrawal symptoms when they stop taking them. Withdrawal symptoms include fatigue , restlessness, mood swings, depression, fatigue, insomnia , reduced sex drive and cravings.
