what does steroids do
Legal uses. Anabolic steroids, or anabolic-androgenic steroids (AAS), are the synthetic (made in a lab) derivatives of the naturally produced hormone testosterone. They promote the growth of muscle (anabolic effect) and the typical male characteristics of puberty (androgenic effect).atural testosterone is the body's main ingredient for this process, but anabolic steroids can serve as a supplement. Once ingested, an AAS travels through the blood stream to the muscle tissue. It is drawn into the muscle cell's receiving dock, called an androgen receptor.
