Retatrutide, identified in the scientific literature as LY3437943, is an investigational synthetic peptide characterized as a triple agonist at the glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon receptors [1][2]. AlphaGrade Peptides supplies it strictly as a research-use-only (RUO) laboratory material. Retatrutide is not FDA-approved; it is an investigational compound offered only for lawful laboratory research.
