Retatrutide

Retatrutide Reference Standard
Triple GLP-1/GIP/Glucagon Agonist · Research Use Only

Triple receptor agonist under active multi-receptor research investigation.

Retatrutide is an investigational 36-amino acid acylated peptide functioning as a simultaneous agonist at GLP-1, GIP, and glucagon receptors — the first triple hormone receptor agonist studied in metabolic research. Its triagonist mechanism engages GLP-1R for insulin secretion and appetite regulation, GIPR for incretin amplification and lipid metabolism, and GCGR for hepatic glucose production and thermogenesis. This multi-receptor engagement produces distinct downstream signaling compared to mono- or dual-agonist compounds. Supplied as lyophilized powder, ≥99% HPLC purity, LC-MS identity confirmed, endotoxin screened.
