GHRP-6 (Growth Hormone-Releasing Peptide-6) is a synthetic hexapeptide and the prototypical ghrelin receptor (GHS-R1a) agonist that potently stimulates growth hormone secretion from the pituitary gland. As one of the first discovered growth hormone secretagogues, this six-amino-acid peptide has been extensively studied for its endocrine effects and serves as a fundamental research tool for investigating growth hormone regulation, appetite modulation, and metabolic pathways. Our research-grade GHRP-6 is synthesized with pharmaceutical purity for precise endocrine research applications.
