GHRP-6
Definition: A first-generation growth hormone secretagogue peptide known for stimulating GH release and appetite through ghrelin-receptor signaling.
What is GHRP-6?
GHRP-6 is a synthetic hexapeptide and one of the earliest growth hormone releasing peptides. It is structurally unrelated to GHRH but activates the ghrelin receptor to trigger endogenous GH release. Its strong appetite-stimulating effect has made it a common reference compound in ghrelin biology research.
How does GHRP-6 work?
By binding GHSR-1a receptors, GHRP-6 stimulates hypothalamic and pituitary pathways that release growth hormone. It also increases hunger through ghrelin-like signaling and can influence prolactin, cortisol, and ACTH more than highly selective compounds such as ipamorelin.
Primary Documented Uses
- Laboratory research on ghrelin and appetite pathways
- Endocrine research into growth hormone pulsatility
- Experimental recovery and body-composition studies
- Historical comparison compound for newer secretagogues
Research Summary
Early human studies confirmed that GHRP-6 produces rapid GH pulses and can synergize with GHRH. Research interest includes cachexia, appetite regulation, and endocrine physiology, but modern therapeutic use is limited by the availability of approved GH-deficiency therapies and insufficient long-term safety data for wellness applications.
Legal and Regulatory Status
GHRP-6 is not FDA-approved for human therapeutic use and is banned by WADA. It is generally classified as a research chemical in the United States.
