For research use only. Not for human consumption.
Overview
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue with high selectivity for the growth hormone secretagogue receptor (GHS-R1a). Unlike other GHSR agonists, Ipamorelin demonstrates minimal stimulation of ACTH, cortisol, prolactin, or aldosterone release at GH-releasing concentrations. Its selectivity profile makes it a preferred research tool for studying isolated GH pulsatility without confounding hormonal effects. Ipamorelin is widely used in GH-axis pharmacology and somatotroph signaling research.

Frequently Asked Questions
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue with high selectivity for the GHS-R1a (ghrelin) receptor. It stimulates pulsatile GH release while demonstrating minimal stimulation of ACTH, cortisol, prolactin, or aldosterone at GH-releasing concentrations.
The standalone Ipamorelin vial contains only the ghrelin receptor agonist, allowing researchers to study isolated GHS-R1a signaling without the GHRH receptor stimulation provided by CJC-1295. The blend combines both mechanisms for researchers studying synergistic GH release.
Unlike other GHSR agonists such as GHRP-6 or GHRP-2, Ipamorelin demonstrates minimal effects on cortisol, prolactin, and aldosterone at concentrations that stimulate GH release. This selectivity profile makes it a preferred tool for studying isolated GH pulsatility without confounding hormonal variables.
