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. Ipamorelin is investigational research material and is not an approved product.

Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) described in the literature as one of the earliest selective growth-hormone secretagogues, supplied as a lyophilized powder for laboratory research use only.

It is studied in the research literature in growth-hormone-axis models; the characterization here reflects that literature only.

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 Ipamorelin 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 bacteriostatic 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 Ipamorelin?

Ipamorelin is a synthetic pentapeptide and one of the earliest selective growth-hormone secretagogues reported in the literature. Ouralus supplies it as a lyophilized powder for laboratory research use only, with a third-party HPLC certificate of analysis published where tested.

What is the amino-acid sequence of Ipamorelin?

The reported sequence is Aib-His-D-2-Nal-D-Phe-Lys-NH2 (Aib = α-aminoisobutyric acid; C-terminal amide), molecular formula C38H49N9O5 (PubChem CID 9831659, CAS 170851-70-4).

Is Ipamorelin third-party tested?

Yes. The lot currently shipping was analysed by Janoshik, an independent laboratory, by HPLC for identity and assayed purity, and assayed 99.897%. The certificate carries verify key JYMNZ4YKPT5X, which you can confirm directly at janoshik.com/verify.

Is Ipamorelin an approved product?

No. Ipamorelin 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.
