GHRP-6 is a synthetic hexapeptide and one of the first growth-hormone secretagogues (developed in the 1980s). It stimulates GH release by activating the ghrelin receptor (GHS-R1a), a pathway distinct from, and synergistic with, GHRH analogs like CJC-1295.

What the market shows
PeptidePrices found 36 in-stock listings from 30 vendors, checked through Oct 10, 2026. The lowest 10mg cost is 51% below the vendor median of $47.98; 15 vendors (50%) fall below that median. 29 of 30 vendors (97%) publish public COA evidence.
A public COA link shows that a vendor publishes testing data. It does not prove that every listed vial has a matching current report. Match the product, strength, batch, and lot before relying on a report.
How this report is calculated
The headline and median use each vendor's lowest whole-package checkout cost to obtain at least 10mg. Smaller packages are multiplied until the target is met, while larger packages retain their full checkout price. The lowest package total is shown only as secondary context because package sizes differ. Known public coupon discounts are applied. Shipping, tax, and unverified promotions are excluded.
Research context
What is GHRP-6? Research, safety, and status
GHRP-6 (Growth Hormone Releasing Peptide-6) is a six-amino-acid peptide that triggers the pituitary to release growth hormone by acting on the ghrelin/GHS-R1a receptor, a different mechanism from GHRH analogs, which is why the two classes are combined for a bigger effect. It was one of the earliest GH secretagogues developed and is among the better-characterized in humans.
Beyond GH release, it shows cardioprotective, wound-healing, and cytoprotective properties in preclinical and early clinical work. It is not FDA-approved; everything below is research context rather than medical guidance.
Key research takeaways
Unlike many research peptides, it has genuine human clinical data, including a Phase I safety trial and a 2024 acute-ischemic-stroke RCT, plus preclinical cardioprotective and cytoprotective findings.
It pairs with a GHRH peptide for a markedly larger combined GH pulse (dual GHS-R1a + GHRH-receptor stimulation). Not FDA-approved; sold for research.

Study highlights
- GHRP-6 (His-D-Trp-Ala-Trp-D-Phe-Lys-NH2), first characterized by Bowers et al. (Endocrinology 1984), acts as a synthetic agonist of the ghrelin/GHS-R1a receptor to potently stimulate pituitary GH release via both hypothalamic GHRH amplification and direct pituitary PI turnover, with maximal GH release requiring intact endogenous GHRH (Pandya et al., JCEM 1998).
- Beyond GH secretagogue activity, GHRP-6 exhibits potent cytoprotective and cardioprotective properties via CD36 and GHS-R1a receptor signaling: in an acute myocardial infarction model, GHRP-6 reduced infarct mass by 78% and decreased myocardial necrosis, effects now categorized as a distinct pharmacological class independent of GH secretion.
- GHRP-6 enhances wound healing and reduces fibrotic scarring: in clinical wound models it accelerated wound closure from the first 24 hours post-injury, and in the rabbit hypertrophic scar model it dramatically reduced exuberant scar formation by activating PPARγ and reducing TGF-β1 and connective tissue growth factor expression.
- Stimulation of appetite via ghrelin-receptor activation is a significant pharmacological effect of GHRP-6, it activates hypothalamic arcuate nucleus neurons and orexin-containing neurons in the lateral hypothalamus to increase food intake, a clinically relevant consideration for cachexia treatment and a key distinction from appetite-neutral GH secretagogues like ipamorelin.
