GHRP-6 (also known as Growth Hormone Releasing Peptide 6) is an early GH-releasing peptide known for strongly stimulating appetite. This page covers what the published research does — and does not — establish about it in relation to growth-hormone support.
GHRP-6 is researched for Growth hormone release — which is why it appears in discussions of growth-hormone support.
Research status: Preclinical and human pharmacology research.
How GHRP-6 is thought to work
GHRP-6 is one of the original growth-hormone-releasing peptides. It stimulates GH release through the ghrelin receptor and is particularly noted for a pronounced increase in hunger, reflecting its ghrelin-mimicking activity.
What it does not establish
Strong appetite and prolactin/cortisol effects reported. Endocrine-active.
Nothing on this page is a recommendation to use GHRP-6, and Selpho publishes no dosing, reconstitution or sourcing information. Read how we decide what goes in the library.

Frequently asked questions
Preclinical and human pharmacology research. Research relevant to this area covers growth hormone release. That is a description of where the research points, not evidence that it will work for you — and Selpho does not provide dosing or medical advice.
Preclinical and human pharmacology research.
Strong appetite and prolactin/cortisol effects reported. Endocrine-active. Always speak to a licensed healthcare professional before considering any peptide.
Growth-hormone release, appetite stimulation, and recovery. Evidence is preclinical and early human pharmacology.
It strongly activates the ghrelin receptor, and ghrelin is the body's "hunger hormone," so appetite effects are prominent.
