Description
Ipamorelin Peptide Overview
Ipamorelin is a synthetic pentapeptide and one of the most selective growth-hormone secretagogues studied in research. It acts as a ghrelin-receptor (GHS-R) agonist and is valued in the literature for stimulating growth-hormone release with minimal impact on other hormones.
Selective Growth-Hormone Release
Ipamorelin binds the ghrelin/growth-hormone-secretagogue receptor on the pituitary and is studied for triggering a clean, pulsatile release of endogenous growth hormone in research models.
Minimal Effect on Cortisol and Prolactin
A defining feature in the research literature is ipamorelin’s selectivity: unlike earlier secretagogues, it is studied for stimulating growth hormone without meaningfully raising cortisol or prolactin.
Supports Recovery and Metabolic Research
Through its growth-hormone axis activity, ipamorelin is investigated in models of tissue recovery, lean-mass regulation and metabolic function.
