Ipamorelin is a selective pentapeptide growth hormone secretagogue (GHS) that stimulates GH release via ghrelin receptor activation (GHS-R1a). Unlike other GHRPs, it does not significantly affect cortisol or prolactin levels, making it a highly targeted peptide for research into GH regulation, metabolic adaptation, and peptide-receptor interactions. With its high stability and specificity, Ipamorelin is widely studied in growth hormone modulation and peptide bioavailability research. For research use only.
