Ipamorelin is a pentapeptide growth hormone releasing peptide (GHRP) that stimulates GH release via the ghrelin receptor with high selectivity — it shows little to no effect on cortisol, prolactin or ACTH at studied doses, unlike older GHRPs such as GHRP-6.
Often discussed alongside CJC-1295 for a combined GH pulse. Human clinical data exists for Ipamorelin (it has been in Phase II trials for post-surgical ileus) but chronic-use safety data does not.
