Selective Androgen Receptor Modulators (SARMs) are synthetic compounds designed to interact selectively with androgen receptors in body tissues such as muscles and bones, aiming to achieve specific anabolic effects without causing undesirable androgenic side effects associated with traditional anabolic steroids. SARMs operate through a combination of mechanisms, including gene transcription activation and protein synthesis regulation. By binding to androgen receptors, SARMs can enhance the expression of genes related to muscle growth and repair, leading to an increase in muscle mass and strength. While SARMs exhibit greater selectivity compared to anabolic steroids, their activity may vary depending on the type of SARM and the tissue in which they are activated. Research surrounding SARMs aims to optimize this selectivity to maximize anabolic benefits while minimizing potential adverse effects, making them of interest in fields such as muscle wasting therapy, osteoporosis, and other conditions related to muscle mass and bone density. However, it is crucial to note that research on SARMs is still in its early stages, and their safety and efficacy in humans must be thoroughly evaluated before widespread use.
