  • Retatrutide (LY-3437943) is a promising anti-obesity agent. It is designed to be a triple hormone receptor agonist, meaning it activates three important receptors in the body: GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide), and GCGR (glucagon receptor). These receptors play crucial roles in regulating glucose levels and metabolic functions in the body.
