What it is
GHRP-6 is a synthetic hexapeptide developed as one of the first potent GHS compounds. Acts at GHSR-1a with significant orexigenic effect.
Evidence snapshot
Category: Growth Hormone. Status: Preclinical. See the references section below for the underlying primary sources.
Mechanism
Activates GHSR-1a to produce GH release. The orexigenic effect (much more pronounced than ipamorelin) limits appetite-modulating applications.
Key research findings
Produced reproducible GH release in rodents and early human studies. Marked appetite stimulation has been demonstrated across species.
Limits of the evidence
Off-label use widespread. Strong appetite effects complicate selectivity. Cortisol and prolactin increases at higher doses. Not approved for any human use.
