What the research literature covers
The characterization below reflects published research literature only. It describes what that literature examines; it is not a statement about use in people. GLP3-RT 10 mg is investigational research material and is not an approved product.
GLP3-RT 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.

Purity, and how to check it yourself
Purity here is a measurement, not a position. The lot currently shipping was analysed by Janoshik, an independent laboratory, by HPLC for identity and assayed purity. We do not test our own material.

Enter that key at janoshik.com/verify and the laboratory returns the report it issued for this batch. You are confirming the result with them, not with us. The full certificate is published as a PDF on the GLP3-RT 10 mg certificate page.
We report HPLC identity and assayed purity only. We do not run heavy-metal, microbial, endotoxin, or sterility analysis, and we do not claim it anywhere on this site.
Handling and stability
- Lyophilized
- −20°C · 24 months (sealed, desiccated)
- Reconstituted
- 2–8°C · weeks (research handling)
Reconstitution solvent: sterile water. Reconstitution parameters are a laboratory-handling matter determined by the researcher; no in-vivo or human-use parameters are provided. The concentration arithmetic for a reconstituted research solution is available in our reconstitution calculator.
Questions
What is GLP3-RT?
GLP3-RT is a synthetic, lipid-modified investigational research peptide in the incretin-peptide family, known in the literature by the development code LY3437943. Ouralus supplies it as a lyophilized powder for laboratory research use only.
What is the molecular formula of GLP3-RT?
The reported molecular formula is C221H342N46O68 (molar mass ≈ 4731 g/mol; PubChem CID 171390338). No CAS number is published for it: the value in circulation could not be confirmed against that CID, which lists none. It is also known by the development code LY3437943.
Is GLP3-RT 10 mg third-party tested?
Yes. The lot currently shipping was analysed by Janoshik, an independent laboratory, by HPLC for identity and assayed purity, and assayed 99.499%. The certificate carries verify key SKYPD9CJHB21, which you can confirm directly at janoshik.com/verify.
Is GLP3-RT 10 mg an approved product?
No. GLP3-RT 10 mg is supplied strictly as a research chemical for laboratory research use only. It is not a drug, not a supplement, and not a food, and it is not for human or animal consumption.
