Retatrutide is a synthetic, lipid-modified research peptide in the incretin-peptide family (a 39–amino-acid peptide), supplied as a lyophilized powder for laboratory research use only.
It is an investigational research peptide studied in the metabolic-signalling literature. The characterization here reflects that research literature only and is not a statement about use in people; the compound is investigational and not an approved product.
Solvent · laboratory handlingSterile water. Reconstitution parameters are a laboratory-handling matter determined by the researcher; no in-vivo or human-use parameters are provided.
Research-literature characterization, provided for research context only. For laboratory research use only. Not for human consumption.
Format is illustrative. We present no assay %, residual-solvent, or lot figures until a real batch is tested and its certificate published. For laboratory research use only. See our full standard →
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.
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.
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.
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.
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.
