Leuphasyl vs KPV
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Leuphasyl
Leuphasyl (Pentapeptide-18) is a cosmetic peptide that reduces muscle tension through a mechanism similar to enkephalins. Often combined with Syn-Ake for enhanced anti-wrinkle effects.
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 | Leuphasyl | KPV |
|---|---|---|
| Mechanism | Mimics enkephalin and binds to enkephalin receptors on muscle cells, reducing acetylcholine release and thereby decreasing muscle contraction intensity. | Inhibits NF-κB activation and reduces inflammatory cytokine production. Enters cells and directly modulates inflammatory signaling without requiring melanocortin receptors. |
| Typical Dosage | Topical: 3-8% concentration in serums. Often used in combination products with other muscle-relaxing peptides. | Oral/sublingual: 200-500mcg 1-3 times daily. Topical formulations for localized inflammation. Also used in enemas for gut inflammation. |
| Administration | Topical application to expression lines. Best results with consistent twice-daily use over 8+ weeks. | Can be taken orally, sublingually, or as suppositories/enemas for gut inflammation. Topical use for skin conditions. Stable orally unlike most peptides. |
| Side Effects | Very well-tolerated topically. No significant adverse effects reported at cosmetic concentrations. | Generally very well-tolerated. Minimal systemic effects due to targeted anti-inflammatory action. |
