LGD-4033, also known as Ligandrol, is a selective androgen receptor modulator (SARM) designed to bind to androgen receptors with high affinity. Preclinical research suggests it may play a role in promoting muscle growth, enhancing bone density, and supporting recovery in experimental models. Its selectivity minimizes off-target effects, making it a valuable tool for studying anabolic and musculoskeletal pathways. This compound is intended strictly for research purposes to investigate its effects on androgen receptor activity and related mechanisms.
