What is Ipamorelin?
Ipamorelin is a pentapeptide growth-hormone-releasing peptide (GHRP) developed to selectively activate the ghrelin / GHS-R receptor. Unlike earlier GHRPs it does not stimulate cortisol, prolactin or aldosterone at research doses.
This selectivity is why Ipamorelin has become the default GHRP in recovery, longevity and body-composition research protocols — it produces clean GH pulses without the endocrine noise of older analogs.
