Ipamorelin is a synthetic pentapeptide and selective growth hormone secretagogue that activates the ghrelin receptor (GHS‑R1a) to stimulate a controlled, physiologic release of growth hormone. Unlike earlier GHRPs, it does not significantly affect cortisol, prolactin, or other pituitary hormones, making it one of the cleanest GH‑releasing peptides studied. Research shows ipamorelin supports GH/IGF‑1 elevation, cellular repair, sleep quality, and recovery, while maintaining a favorable safety profile. Supplied strictly for laboratory research.
