This is educational information, not medical advice, and The Peptide University does not sell peptides, supplies, or supplements. Many compounds discussed here are sold as “research chemicals” and are not approved for human use outside of clinical trials. Laws vary by country, and nothing here is a recommendation to obtain or use anything. Talk to a qualified clinician about your own situation.
GHRP-6 was the first synthetic peptide shown to reliably release growth hormone in a dose-related way. It's investigational and not an approved consumer product.
How it works
Like the others, it works through the ghrelin/GH-secretagogue receptor and synergizes with GHRH. Of the GHRPs, it most strongly drives ghrelin-like appetite signaling.
The evidence
It has reproducible GH-releasing activity and some preclinical work on tissue protection and wound healing, but human clinical use as an anabolic/anti-aging agent remains unconfirmed.
Safety
Strong appetite increase is the hallmark, plus the usual GH-stimulation effects (water retention, tingling) and possible cortisol/prolactin effects. Long-term human safety is not established.
FAQ
QWhy does it cause so much hunger?
It strongly activates the ghrelin ('hunger hormone') pathway, more so than newer, more selective secretagogues.
QIs it approved?
No — investigational.
