Ipamorelin

Ipamorelin is a synthetic pentapeptide growth hormone secretagogue, Aib-His-D-2-Nal-D-Phe-Lys-NH₂, developed by Novo Nordisk under the code NNC 26-0161 and described in 1998 as the first secretagogue of its class selective for growth hormone release.^{9849822, 9879640} This listing is a single 10 mg vial of lyophilized peptide supplied to qualified laboratories for in vitro and preclinical research. The current batch’s certificate of analysis, with its purity and endotoxin reports, sits in the certificate card on this page.

Research reagent identity

Three of the five residues are non-standard (Aib and two D-amino acids), which is why ipamorelin is usually written in three-letter code rather than as a one-letter string.

Batch documentation

The certificate card on this page shows batch RRL-2146000-P, purity 99.38%, date 27 JUN 2026, lab horizonanalytical.com. The linked purity PDF from Horizon Analytical lists Revitalized Research LLC as the client, a lab-received date of 06/23/2026 and analysis on 06/27/2026, and reports UPLC/MS results against the specification: compound test Ipamorelin (found: Ipamorelin), quantity 9.79 mg against a 10 mg label, purity 99.38% against a >98% specification. A separate endotoxin report, lot RRL-2146000-E, gives a result of <0.05 EU/mL.

To tie a vial to its paperwork, compare the lot printed on the label with the batch on the card, then confirm the compound name, CAS and CID inside the PDF. Certificates for other products and batches are kept in the COA library, and the guide how to verify a peptide COA walks through checking a report with the issuing lab. For reading the sections of a certificate, see how to read a peptide COA. Batch certificates are posted when available.

Storage and handling

Keep the sealed vial cold, dry and away from light until it is used; lyophilized peptides are most stable before reconstitution. Reconstitution water is not included and is sold separately as reconstitution solution. Handle the material only in a laboratory setting with gloves and labelled containers, and record the batch number in your notebook. General guidance is in peptide storage basics for research labs.
