Studysummary This article reviews the development of selective androgen receptor modulators and myostatin inhibitors as performance-enhancing drugs, highlighting ongoing challenges in achieving truly tissue-selective anabolic agents and reporting no new experimental findings. Our plain-language summary of this paper — not a Tressless recommendation.
The document discusses the mechanisms of anabolic steroids, selective androgen receptor modulators (SARMs), and myostatin inhibitors. Anabolic steroids like testosterone induce muscle hypertrophy by up-regulating androgen receptors in skeletal muscle. SARMs, such as YK11, selectively stimulate the androgen receptors in muscle and bone, increasing muscle mass and bone density without the side effects of traditional anabolic steroids. Myostatin inhibitors increase muscle mass and strength by blocking the activity of myostatin, a protein that inhibits muscle growth. However, there are potential adverse effects: hypogonadism risk with anabolic steroids, unknown long-term effects of SARMs, and potential tendon brittleness with myostatin inhibitors.
