Mechanism

Incretin dual agonist with GIP preference. Drives insulin secretion and gastric emptying modulation.

Simultaneous agonism of GLP-1, GIP, and glucagon receptors drives glycemic modulation and adipose mobilization.

Body-Protective Compound. Upregulates VEGFR2 signaling, promotes fibroblast migration, and accelerates tendon/ligament repair in preclinical models.
