YK-11 Ultima Pharmaceuticals at a Glance
YK-11 is a steroidal selective androgen receptor modulator (SARM) that operates through a unique dual mechanism in preclinical studies. Unlike traditional non-steroidal SARMs, YK-11 demonstrates partial androgen receptor agonist activity while simultaneously functioning as a myostatin inhibitor through follistatin induction in cell culture models. This distinctive compound features a steroid-like chemical structure with CAS number 1370003-76-1 and molecular formula C₂₅H₃₄O₆, setting it apart from conventional SARMs available through Stroid UK Shop. Preclinical investigations have focused on its ability to modulate both androgenic pathways and myostatin-regulated muscle development mechanisms in laboratory settings.
Laboratory Applications
Research scientists examine YK-11 for its unique myostatin inhibition properties, which occur through enhanced follistatin expression in muscle cell cultures. This mechanism has generated interest among researchers investigating muscle biology and myostatin pathway modulation. Studies explore how YK-11’s partial androgen receptor agonism combines with its myostatin-inhibiting effects to influence cellular processes. Investigators analyse its tissue selectivity patterns and compare its activity profile to other compounds in the myostine research category. The compound’s steroidal backbone provides researchers with opportunities to evaluate structure-activity relationships between steroid-based and conventional SARM architectures. Additional research applications include investigating its molecular interactions with follistatin promoter regions and examining its effects on muscle protein synthesis pathways in controlled laboratory environments.
