GHRP-6

Research compound. This is not a dietary supplement. Unless it is identified as an approved prescription drug, it is not approved by the FDA for human use. This page summarizes published research for education only; we do not sell it or link to sellers.

GHRP-6. First-generation ghrelin mimetic that produces a strong appetite signal alongside GH release.

How it works. Binds GHS-R1a in the pituitary for GH release and in hypothalamic NPY/AgRP neurons to trigger appetite.

What the research supports. 3 graded claims. Strongest: Useful in cachexia and appetite-loss research (preclinical).

Hormonal impact. Effects on Growth hormone, Ghrelin signaling, Cortisol, Prolactin.

Side effects and interactions. 1 medication interaction listed. Serious: Insulin resistance with chronic high-dose use.

Stacking. Pairs well with CJC-1295. Avoid combining with Active malignancy.

Common forms. Available as Subcutaneous injection.

Community. Experiences from people who have tried GHRP-6. Anecdotes are not medical advice.

What it is

GHRP-6 is a synthetic hexapeptide that activates the ghrelin receptor, releasing GH and producing a pronounced hunger response.

How it works

Binds GHS-R1a in the pituitary for GH release and in hypothalamic NPY/AgRP neurons to trigger appetite.

Pathways

  • GHS-R1a
  • NPY/AgRP appetite circuit

Effects

  • ↑Appetite increases
  • ↑GH / IGF-1 axis activity increases
  • +Recovery in catabolic states supports

Strong: consistent results across large trials or meta-analyses. Moderate: several trials, mostly positive. Limited: small or mixed studies. Preclinical: animal or cell research only.
