GHRP-6 (Growth Hormone-Releasing Peptide-6) is one of the first synthetic ghrelin mimetics, a hexapeptide developed in the 1980s and extensively studied in the scientific literature. As noted in peer-reviewed research, it acts as a potent agonist at the growth hormone secretagogue receptor (GHS-R1a), stimulating GH release from the pituitary via PKC and Ca²⁺ signaling pathways independently of GHRH (springer.com). This research-grade lyophilized powder is synthesized under strict quality controls and includes full analytical documentation, making it suitable for neuroendocrine, metabolic, and receptor-signaling research applications.

Frequently asked questions
How should I reconstitute this peptide?
Use bacteriostatic water for short-term lab storage. Direct the diluent down the side of the vial, swirl gently — do not shake.
What is the shelf life?
Lyophilized peptide stored at −20°C is stable for 24+ months. Reconstituted peptide should be refrigerated and used within 2–4 weeks.
Do you ship internationally?
We currently ship within the United States only. International researchers should contact our bulk team for institutional quotes.
