Mechanism of action

Retatrutide is a synthetic triple agonist targeting the GIP, GLP-1, and glucagon receptors simultaneously. Research models investigate the combined contribution of all three pathways to glucose regulation, lipid metabolism, and energy expenditure.

The triple-receptor mechanism distinguishes it as a next-generation incretin research compound and a frequent subject of comparative agonist studies.
