Palmitoyl Tripeptide-1 vs SNAP-8
A side-by-side research comparison of Palmitoyl Tripeptide-1 and SNAP-8 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Palmitoyl Tripeptide-1 | SNAP-8 |
|---|---|---|
| Full name | Palmitoyl Tripeptide-1 (Pal-GHK) | SNAP-8 (Acetyl Octapeptide-3) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| Mechanism | Functions as matrikine signal, mimicking collagen fragments that trigger fibroblasts to produce new collagen. Palmitoyl enables deeper skin penetration. | More effectively competes with SNAP-25 for SNARE complex incorporation due to longer sequence, providing greater vesicle-membrane fusion inhibition. |
| Molecular weight | 578.8 Da | 1,075 Da |
| Half-life | 8-12 hours (topical) | 8-14 hours (topical) |
| Bioavailability | Good (topical with lipid modification) | Moderate (topical) |
| Typical dose | 2-5% in formulation | 3-10% solution |
| Frequency | 1-2x daily | 2x daily |
| Route | Topical | Topical |
