About Retatrutide
Retatrutide — also referred to as LY3437943 — is a synthetic peptide acting as a triple agonist at three receptors: GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide), and glucagon. It is one of the most extensively studied next-generation incretin compounds in published preclinical research literature, particularly in research areas examining metabolic and incretin signalling pathways across UK and international research environments.
