About the research

Ipamorelin (NNC 26-0161) is a Novo Nordisk-developed ghrelin-mimetic pentapeptide and one of the cleanest growth-hormone secretagogues characterized. Its receptor selectivity for GHS-R1a — and absence of off-target HPA-axis activation seen with earlier GHRPs — has made it the canonical research tool for studying pulsatile somatotroph signaling and combination protocols with GHRH analogs.

Mechanism, reported research areas, literature dose ranges and co-factor studies are on the research page, with sources. Nothing there is a claim about this product.
