Retatrutide (LY3437943) is a triple‑receptor agonist peptide targeting GCGR, GIPR and GLP‑1R. Its EC50 values for human GCGR, GIPR and GLP‑1R are 5.79 nM, 0.0643 nM and 0.775 nM respectively. For mouse receptors, EC50 values are 2.32 nM (GCGR), 0.191 nM (GIPR), 0.794 nM (GLP‑1R). In‑vivo studies show Retatrutide Acetate improves glucose tolerance via GIP / GLP‑1 pathways in ipGTT models. GCGR activation contributes to notable weight‑loss effects and higher energy expenditure. This product is intended for obesity‑related scientific research.
