The selective androgen receptor modulators (SARMs) are androgen receptor ligands that bind to androgen receptors on target cells and exhibit a more pronounced anabolic effect at the expense of the androgenic effect on the latter. The aim of the article is to explain what SARMs are and how they are connected with sports. We used over 300 articles for the last 20 years connected with SARMs. Recently, the interest in these new molecules and their use has grown significantly, including in sports, which has led to their listing on the WADA prohibited list. In recent years, a lot of data have been gathered, both on the mechanism of action of a number of steroidal and non-steroidal representatives of this class of substances and on the adverse side effects of their use, as the latter should be well-known to sports doctors and especially to amateurs practicing in their free time and willing to increase their muscle mass with a view to preventing any potential health risks.
