Retatrutide (LY3437943) is a novel unimolecular triple agonist that simultaneously engages three receptor pathways: glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon receptors. This triple-receptor mechanism distinguishes it from dual agonists and single-agonist compounds currently available for research.
Development Stage
Retatrutide is an investigational compound in Phase 3 clinical development. Sponsor-reported trial results are summarised with sources in the Research Library rather than here — product pages on this site do not carry clinical efficacy data.
