What is Ipamorelin?

Ipamorelin is a synthetic pentapeptide belonging to the class of growth hormone-releasing peptide (GHRP) analogs. With the molecular formula C38H49N9O5 and a molecular weight of 711.85 Da, this selective ghrelin receptor agonist consists of five amino acids: Aib-His-D-2-Nal-D-Phe-Lys-NH2. Developed in the 1990s by Novo Nordisk, Ipamorelin is distinguished by its high selectivity for the growth hormone secretagogue receptor (GHSR-1a) without significant activation of cortisol or prolactin receptors.

These structural characteristics make Ipamorelin one of the most studied GHRP analogs in preclinical research.

Analysis and identity

Every batch is tested independently by an external laboratory. The certificate of analysis for this product has not yet been published on this page.

Available variants

Ipamorelin is available in 5mg and 10mg. The current price for each is shown with the product options on this page.

Storage and Handling

Lyophilized Ipamorelin should be stored at -20°C to -80°C, protected from light and moisture. Under these conditions, the peptide remains stable for at least 24 months from the production date.

For reconstitution, sterile water or bacteriostatic water is recommended at a ratio of 1-2 ml per 5mg of peptide. After reconstitution in sterile water, the solution is stable for 72 hours at 2-8°C. When using bacteriostatic water, the solution can be stored for up to 14 days at refrigerator temperature. Avoid repeated freezing and thawing to prevent aggregation.
