S4, also known as Andarine or Andarine S4, is a selective androgen receptor modulator (SARM). It was developed by GTX Inc. for the treatment of conditions such as muscle wasting, osteoporosis, and benign prostatic hyperplasia (enlarged prostate). However, it is primarily known for its potential performance-enhancing effects and its use by athletes and bodybuilders.
Andarine works by selectively binding to androgen receptors in muscle and bone tissues, mimicking the effects of testosterone. This selective action is believed to lead to an increase in muscle mass, strength, and bone density without causing many of the unwanted side effects associated with traditional anabolic steroids.
Although Andarine has been researched for its potential therapeutic benefits, it is important to note that its use for human consumption has not been approved by regulatory agencies like the FDA. It is often sold as a research chemical or dietary supplement, and its safety and efficacy for human use have not been fully established.
Furthermore, like other SARMs, Andarine may have potential side effects, including hormonal imbalances, suppression of natural testosterone production, and other health risks. Therefore, its use should be approached with caution and under the guidance of a qualified healthcare professional. Additionally, the use of Andarine or other SARMs may be banned in competitive sports due to their potential performance-enhancing effects.
