About this compound

MW: ~4482 g/mol | Purity: >=97% HPLC | Lyophilized powder, 5mg/vial

Product Details

Retatrutide is a synthetic peptide with a molecular weight of 4892.68 g/mol and molecular formula C228H356N50O67. Supplied as a lyophilised solid, each batch is verified to ≥97% purity via HPLC analysis and accompanied by a Certificate of Analysis (COA).

Retatrutide is soluble in water at 1 mg/ml. For optimal stability, store the unopened vial at -20 °C, desiccated, protected from light. Stable for up to 14 days at 2–8 °C in aqueous solution under sterile conditions.

Triple agonist targeting GIP, GLP-1, and glucagon receptors. Studied for multi-receptor energy expenditure and glucose homeostasis.

Why LarnaLabs

Every compound we supply is synthesized in ISO-certified GMP facilities using automated solid-phase peptide synthesis, ensuring batch-to-batch consistency and accurate sequencing.

Each batch undergoes independent third-party testing — HPLC for purity verification (≥97%), mass spectrometry for identity confirmation, and endotoxin screening (<1 EU/μg). A full Certificate of Analysis ships with every order.

We offer free worldwide shipping with temperature-controlled packaging, anonymous checkout for your privacy, and responsive support from a team that understands research-grade compounds.
