GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide that stimulates growth hormone release through the ghrelin/GHS-R1a receptor pathway. As one of the first-generation growth hormone secretagogues, GHRP-6 produces potent GH release along with notable appetite stimulation (via ghrelin mimicry). While largely superseded by more selective analogs like Ipamorelin in clinical settings, GHRP-6 remains an important research tool for studying GH axis physiology and ghrelin receptor signaling. We provide pharmaceutical-grade GHRP-6 in lyophilized form with verified purity exceeding 99% by HPLC.

Bowers CY et al. (1991) published in Endocrinology the foundational research characterizing GHRP-6 as a potent growth hormone secretagogue acting through a novel receptor pathway distinct from GHRH.
Research by Arvat E et al. (2001) in The Journal of Clinical Endocrinology & Metabolism demonstrated GHRP-6's synergistic effects with GHRH on GH release and appetite stimulation mechanisms.
A comparative study in European Journal of Endocrinology (2004) detailed GHRP-6's pharmacokinetic profile and receptor binding characteristics relative to newer GH secretagogues.
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide that stimulates growth hormone release through ghrelin/GHS-R1a receptor activation. It was one of the first synthetic GH secretagogues developed.
We supply GHRP-6 at ≥99% (HPLC) purity with comprehensive Certificate of Analysis including mass spectrometry confirmation and amino acid analysis.
GHRP-6 produces stronger GH release but with significant appetite stimulation and potential cortisol/prolactin elevation. Ipamorelin is more selective with minimal appetite effects, making it preferred for most research protocols.
