Retatrutide for laboratory research
An investigational single-peptide agonist of the GIP, GLP-1 and glucagon receptors. Its regulatory position must be checked for every destination.
Overview
Retatrutide (development code LY3437943) is an investigational synthetic peptide designed to act as an agonist at three receptors: the GIP receptor, the GLP-1 receptor and the glucagon receptor. It has been studied in clinical development programmes.
Retatrutide's regulatory status differs between countries and is changing as development continues. NEXA reviews the current position for the destination, together with the requesting organisation and research purpose, before any supply is considered.

No purity, testing or stock claim is published without supporting records. Read our guide on how to read a peptide Certificate of Analysis.
Regulatory status and eligibility
Retatrutide is an investigational compound. Supply is considered only to qualified organisations, for non-clinical laboratory research, where the destination permits it.
Requests must come from a laboratory or research organisation and describe a legitimate non-clinical research purpose. Personal-use requests are declined. Import requirements in the destination country are the customer's responsibility.
