Detection of LGD-4033 Metabolites in Camel Urine, Plasma, and Hair Following Oral Administration for Doping Control.

Rationale: LGD-4033, a selective androgen receptor modulator (SARM), is recognized for promoting muscle growth and enhancing athletic performance. Its potent anabolic effects have led to its prohibition in both human and animal sports. Although initial in vitro studies have offered insights into its metabolism, an in-depth in vivo analysis is necessary to fully understand its metabolic pathways.
