Ipamorelin | Selective Growth Hormone Secretagogue

Research Overview

Ipamorelin is a pentapeptide and selective growth hormone secretagogue (GHS) that mimics the action of ghrelin. It is notable in research for its selectivity — studies suggest it stimulates growth hormone release with minimal effect on cortisol and prolactin compared to other secretagogues.

Research has examined Ipamorelin’s mechanism of action through the GHS receptor (GHSR-1a), its pulsatile GH release profile in animal models, and its potential applications in models of age-related GH decline, body composition research, and bone density studies. It is frequently studied in combination with CJC-1295.
