Anabolic steroids, technically known as anabolic-androgenic steroids (AAS), are drugs that are structurally related to the cyclicsteroid rings system and have similar effects to testosterone in the body. They increase protein within cells, especially in skeletal muscles. Anabolic steroids also have androgenic and virilizing properties, including the development and maintenance of masculine characteristics such as the growth of the vocal cords, testicles (primary sexual characteristics) and body hair (secondary sexual characteristics).
Anabolic steroids were first made in the 1930s, and are now used therapeutically in medicine to stimulate muscle growth and appetite, induce male puberty and treat chronic wasting conditions, such as cancer and AIDS. The American College of Sports Medicine acknowledges that AAS, in the presence of adequate diet, can contribute to increases in body weight, often as lean mass increases and that the gains in muscular strength achieved through high-intensity exercise and proper diet can be additionally increased by the use of AAS in some individuals.
Health risks can be produced by long-term use or excessive doses of anabolic steroids. These effects include harmful changes incholesterol levels (increased low-density lipoprotein and decreased high-density lipoprotein), acne, high blood pressure, liver damage(mainly with oral steroids), and dangerous changes in the structure of the left ventricle of the heart.[4] Conditions pertaining to hormonal imbalances such as gynecomastia and testicular size reduction may also be caused by anabolic steroids.
Ergogenic uses for anabolic steroids in sports, racing, and bodybuilding as performance-enhancing drugs are controversial because of their adverse effects and the potential to gain unfair advantage is considered cheating. Their use is referred to as doping and banned by all major sporting bodies. For many years, AAS have been by far the most detected doping substances in IOC-accredited laboratories.[5][6]In countries where AAS are controlled substances, there is often a black market in which smuggled, clandestinely manufactured or evencounterfeit drugs are sold to users.
