Description
Retatrutide is a synthetic 39-amino acid peptide that functions as a potent triple agonist targeting glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon receptors. It exhibits strong glucose-lowering effects and promotes substantial weight loss through integrated modulation of these key metabolic pathways. Retatrutide’s unique activity profile includes delayed gastric emptying, reduced food intake, and improved insulin secretion and sensitivity.

Research Applications
- Obesity and metabolic disorder studies focusing on multi-receptor agonism
- Investigation into glycemic control and insulin secretion enhancement
- Preclinical and clinical evaluation of weight reduction and appetite modulation
- Studies on cardiovascular and metabolic benefits of triple receptor activation
Key Research & Reports
Mechanism of Action
Retatrutide activates three hormone receptors: GLP-1, GIP, and glucagon receptors. This triagonism induces enhanced insulin secretion in a glucose-dependent manner, suppresses glucagon release, delays gastric emptying, and reduces appetite. Together, these effects promote significant weight loss and improved metabolic outcomes in research models.
