Research Overview
What Ipamorelin is
Ipamorelin is a synthetic pentapeptide with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2 and a molecular weight of approximately 712 Da. It incorporates several non-natural residues, including aminoisobutyric acid (Aib) and D-2-naphthylalanine, which contribute both to its stability and to its receptor selectivity. It was first described in 1998 by Raun and colleagues at Novo Nordisk.
Research background
Ipamorelin belongs to the growth-hormone secretagogue class and is characterised in the literature as one of the more selective agonists at the ghrelin receptor (GHS-R1a), with reduced activity at other targets compared with earlier compounds such as GHRP-6. This selectivity has made it a preferred tool compound in receptor pharmacology and in cell and animal models where a clean secretagogue stimulus is required. Megalab supplies Ipamorelin as a research reagent only.
Specification
Each vial contains 5mg of Ipamorelin as a lyophilised powder. Purity is verified by HPLC at ≥99% on every batch. The batch record on this page shows the current lot where published, and a Certificate of Analysis is available on request. Ipamorelin is also available in bundle form with CJC-1295 no DAC and with Tesamorelin.
Handling and storage
Store unopened vials at −20°C, protected from light. Bring to room temperature before opening. Reconstitute with bacteriostatic water added slowly down the inside of the vial, swirling gently to dissolve. Store reconstituted solution at 2–8°C and use within 30 days.
Supplied for laboratory research use only.

Frequently Asked Questions
What makes Ipamorelin more selective than GHRP-6?
Its non-natural residues, particularly D-2-naphthylalanine and Aib, were selected during development to favour the ghrelin receptor over other targets, giving a narrower activity profile than first-generation secretagogues.
Which bundles include Ipamorelin?
The Ipamorelin + CJC-1295 Bundle and the Tesamorelin + Ipamorelin Bundle. Both pair it with a GHRH analogue.
What purity is Ipamorelin supplied at?
Every batch is released at ≥99% purity by HPLC, with the current lot shown in the batch record on this page and a Certificate of Analysis available on request.
