Ipamorelin: compound identifiers, research literature, and verified purity
99.897%assayed by HPLC at Janoshik

Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2), CAS 170851-70-4. Ouralus supplies it as a lyophilized powder for laboratory research use only. The Janoshik report assayed 99.897% by third-party HPLC and prints no batch ID, and that report is published here with a key you can confirm with the laboratory yourself.

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. A report from Janoshik, an independent laboratory, is published for Ipamorelin: assayed purity and net content. It prints no batch ID, so it does not identify a lot. 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 report image on the Ipamorelin certificate page.
We report assayed purity and net content only. We do not run heavy-metal, microbial, endotoxin, or sterility analysis, and we do not claim it anywhere on this site.

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. A report from Janoshik, an independent laboratory, is published for Ipamorelin; it prints an assayed purity of 99.897%. The report prints no batch ID, so it does not identify a lot. 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.
