They have been banned by many sports because of their danger to health. Their exact effect on the body is still a matter of scientific debate.
Anabolic steroids can improve the body's capacity to train and compete at the highest level.
They reduce the fatigue associated with training, and the time required to recover after physical exertion. They also promote the development of muscle tissue in the body, with an associated increase in strength and power. This is achieved by stimulating the production of protein in the body. However, some of the increased muscle bulk may be due to the laying down of water and minerals, so the increase in strength may not be as pronounced as expected. Anabolic steroids promote the growth of many tissues in the body by stimulating the release of the hormone testoterone.
