Selective androgen receptor modulators (SARMs) are a class of investigational pharmacological agents that exhibit tissue-selective anabolic effects via their interaction with androgen receptors (AR) [1]. These compounds are currently being explored for their potential to promote muscle hypertrophy and improve physical performance without the unwanted side effects typically associated with anabolic-androgenic steroids (AAS), such as […]
A Comparative Analysis of RAD-140 Purity in Commercial Selective Androgen Receptor Modulator Products Date: 4 October 2025 Abstract Selective androgen receptor modulators (SARMs) are a class of drugs designed to stimulate androgen receptors in specific tissues, such as muscle and bone, without negatively affecting other tissues like the prostate. Therefore, SARMs are currently being studied […]
Highlights Our observations of user before-and-after transformations suggest that Ostarine may benefit researchers exploring muscular strength and hypertrophy. Some athletes take Ostarine for performance-enhancement purposes, helping them achieve their sporting goals. However, major sporting organizations prohibit selective androgen receptor modulator (SARM) use, such as the World Anti-Doping Agency (WADA), the United States Anti-Doping Agency (USADA), […]
LGD-4033 (Ligandrol/VK5211/Anabolicum) is a selective androgen receptor modulator (SARM) used by certain weightlifters for bulking purposes to increase muscle strength and hypertrophy (1). Ligandrol and other SARMs show promise for the potential treatment of cachexia and sarcopenia due to their anabolic effects and tissue selectivity (2). LGD-4033 strongly binds to the androgen receptor, similar to […]
Selective androgen receptor modulators (SARMs) are not approved by the FDA, and thus, they are not considered safe at this time. Despite a lack of approval, SARMs are becoming increasingly utilized in bodybuilding circles due to a misconception that they are safe alternatives to anabolic steroids. Thus, just like with steroids, there are SARMs with […]
