Leuphasyl vs Palmitoyl Tripeptide-1
A side-by-side research comparison of Leuphasyl and Palmitoyl Tripeptide-1 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Leuphasyl | Palmitoyl Tripeptide-1 |
|---|---|---|
| Full name | Leuphasyl (Pentapeptide-18) | Palmitoyl Tripeptide-1 (Pal-GHK) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| Mechanism | Binds enkephalin receptors on neuronal membranes, reducing calcium influx and neurotransmitter release at the presynaptic level. Works upstream of argireline. | Functions as matrikine signal, mimicking collagen fragments that trigger fibroblasts to produce new collagen. Palmitoyl enables deeper skin penetration. |
| Molecular weight | 599.7 Da | 578.8 Da |
| Half-life | 6-10 hours (topical) | 8-12 hours (topical) |
| Bioavailability | Moderate (topical) | Good (topical with lipid modification) |
| Typical dose | 3-5% solution | 2-5% in formulation |
| Frequency | 2x daily | 1-2x daily |
| Route | Topical | Topical |
