Growth Hormone Release
GHRP-6 produces potent, dose-dependent GH release through ghrelin receptor (GHSR-1a) activation. It was the compound whose receptor binding research led to the discovery of ghrelin — the endogenous hunger hormone — making it historically foundational for GH secretagogue pharmacology.
Appetite Stimulation
GHRP-6 produces the strongest appetite stimulation of any commonly used GHRP. For researchers and individuals struggling to achieve caloric surplus (hardgainers, recovery from illness), this is considered a feature rather than a side effect. Intense hunger onset occurs within 20 minutes and lasts 30–60 minutes.
Cytoprotective Effects
Some research suggests GHRP-6 has cardioprotective and hepatoprotective effects independent of GH release. Studies show reduced ischemia-reperfusion injury and protection against liver fibrosis in animal models, possibly through ghrelin receptor-mediated anti-inflammatory pathways.
