GHRP-6 vs KPV
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
GHRP-6
Growth Hormone Releasing Peptide 6 (GHRP-6) is one of the first synthetic growth hormone secretagogues discovered. It stimulates significant GH release but is known for causing intense hunger.
Full details →KPV
KPV is a tripeptide (Lys-Pro-Val) derived from alpha-melanocyte-stimulating hormone (α-MSH). It retains the potent anti-inflammatory properties of the parent hormone without the tanning or other melanocortin effects.

| Aspect | GHRP-6 | KPV |
|---|---|---|
| Mechanism | Acts as a ghrelin mimetic, binding to the GHS-R receptor in the pituitary and hypothalamus. Stimulates GH release and also significantly increases appetite by mimicking ghrelin's hunger-signaling effects. | Inhibits NF-κB activation and reduces inflammatory cytokine production. Enters cells and directly modulates inflammatory signaling without requiring melanocortin receptors. |
| Typical Dosage | Typical dosing: 100-300mcg administered 2-3 times daily. Often combined with GHRH peptides like CJC-1295 for synergistic effects. | Oral/sublingual: 200-500mcg 1-3 times daily. Topical formulations for localized inflammation. Also used in enemas for gut inflammation. |
| Administration | Subcutaneous injection. Best administered on an empty stomach. The strong hunger response can be beneficial for those trying to gain weight but challenging for cutting. | Can be taken orally, sublingually, or as suppositories/enemas for gut inflammation. Topical use for skin conditions. Stable orally unlike most peptides. |
| Side Effects | Intense hunger (most notable effect), water retention, increased cortisol and prolactin, tingling/numbness, and potential blood pressure changes. | Generally very well-tolerated. Minimal systemic effects due to targeted anti-inflammatory action. |
