When sourcing research peptides from any supplier, it is worth confirming a few things first: that a Certificate of Analysis is provided for the specific batch you receive, that purity is verified by an independent third-party laboratory using HPLC and mass spectrometry, that each vial carries a batch number you can match to its COA, and that the material is handled and shipped with temperature protection.

Orion Peptides supplies retatrutide strictly for laboratory research. It is not approved for human or veterinary use, and we do not provide reconstitution instructions, dosing guidance, or recommendations of any kind.

Retatrutide, also identified by the development code LY3437943, is a synthetic peptide developed by Eli Lilly and Company. It acts as an agonist at three receptors simultaneously — GIP, GLP-1, and glucagon — which is why it is commonly described as a triple agonist. Peptides that act on a single receptor or two receptors are more common; the three-receptor mechanism is what distinguishes it in the literature.

Retatrutide is an investigational compound. It is currently in Phase 3 clinical trials, where it is being evaluated in obesity and type 2 diabetes, and it has not been approved by the FDA, or by any other regulatory agency, for any indication. No approval date has been confirmed.
