Murzakanov tested positive for the low-level presence of a metabolite of LGD 4033, a prohibited at all times substance in the class of anabolic agents on the UFC Prohibited List, from an out of competition sample collected from him on October 8, 2024. A sealed bottle of a purported dietary supplement that Murzakanov used leading up to this sample provision was procured and sent to the UFC ADP’s testing laboratory, Sports Medicine and Research Testing Laboratory (SMRTL), in Salt Lake City, Utah, for analysis. The analysis found a low-level presence of LGD-4033 in the sealed supplement, despite not being listed on its labeled ingredients.
