What is Retatrutide?

Retatrutide is a synthetic, lipid-modified investigational research peptide in the incretin-peptide family. Ouralus supplies it as a lyophilized powder for laboratory research use only.

What is the molecular formula of Retatrutide?

The reported molecular formula is C221H342N46O68 (molar mass ≈ 4731 g/mol; PubChem CID 171390338, CAS 2381089-83-2). It is also known by the development code LY3437943.

Who can order?

These materials are supplied strictly for laboratory and research use, to purchasers of legal age. They are not supplements, drugs, or foods, and are not for human or animal consumption.

Is Retatrutide legal to buy?

Retatrutide is supplied strictly as a research chemical for laboratory research use only — it is not a drug, supplement, or food, and not for human or animal consumption. It ships to purchasers of legal age for research use. Buyers are responsible for compliance with the laws that apply to research materials in their own jurisdiction.

Is a certificate of analysis provided with Retatrutide?

Yes — each tested lot of Retatrutide ships with a third-party HPLC certificate of analysis from Janoshik, independently verifiable by lot (verify key SKYPD9CJHB21). The current lot assayed 99.499%. We publish the certificate before making any purity claim; this is a research chemical for laboratory use only.
