Quick Overview
Retatrutide is an investigational unimolecular triple receptor agonist targeting glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon receptors. It is designed to enable integrated modulation of appetite signalling, insulin secretion, and energy expenditure in metabolic research models.

Full Research Overview
Retatrutide (research code: LY3437943) represents a next-generation class of multi-receptor agonists engineered to simultaneously activate GLP-1, GIP, and glucagon receptors within a single molecular framework.
Activation of the GLP-1 receptor is associated with delayed gastric emptying and central appetite regulation via hypothalamic pathways. GIP receptor engagement contributes to glucose-dependent insulinotropic activity, enhancing pancreatic beta-cell responsiveness and supporting glycaemic regulation. The addition of glucagon receptor agonism introduces a distinct metabolic dimension, promoting increased energy expenditure, hepatic lipid oxidation, and thermogenic processes.
