LGD-4033 (CAS 1165910-22-4) – Selective Androgen Receptor Modulator SARM API

LGD-4033 (CAS 1165910-22-4) is a high-purity pharmaceutical API classified as a potent SARM, featuring a synthetic non-steroidal molecular structure with high affinity for androgen receptors (Ki = 1 nM). It selectively binds to receptors in muscle and bone tissues, activating anabolic pathways to promote lean muscle growth and bone density improvement—without the androgenic side effects on prostate or sebaceous glands associated with traditional steroids. This premium API boasts excellent oral bioavailability and stable pharmacokinetics, ensuring consistent performance for research and formulation.

It caters to the core needs of pharmaceutical researchers, biotech companies, and performance-related product developers. Initially developed for treating muscle wasting (sarcopenia), cachexia, and osteoporosis, it is widely studied for its ability to enhance strength, accelerate post-workout recovery, and support lean mass gains. Produced under strict GMP standards, each batch undergoes rigorous purity testing (≥99.99% purity) to meet international quality requirements, eliminating impurities that could impact research validity. For businesses prioritizing targeted efficacy and safety in muscle health and performance formulations, this LGD-4033 API serves as a valuable raw material for innovative therapeutic and research applications.
