Palmitoyl Tripeptide-1 vs Palmitoyl Tetrapeptide-7 — Peptide Comparison Palmitoyl Tripeptide-1 vs Palmitoyl Tetrapeptide-7 — compare dosing, benefits, safety profiles, side effects, and how they stack. See which peptide is right… At a Glance Dose Range Palmitoyl Tripeptide-1 0.5%–3% % Palmitoyl Tetrapeptide-7 0.5%–8% % Frequency Once daily Administration Topical Cycle Length Ongoing/indefinite Onset Speed Moderate (1-2 weeks) Evidence Level Limited human trials Efficacy Collagen Production Anti-Aging Skin Firmness Anti-Inflammatory Skin Barrier Support Technical Data Molecular Formula C30H54N6O5 Molecular Weight 578.8 Da Half-Life Limited data; peptide is susceptible to enzymatic degradation in skin but palmitoylation improves stability compared to unmodified GHK Bioavailability Enhanced topical penetration via palmitoyl lipid modification; reaches dermis where fibroblasts reside CAS Number 147732-56-7 C34H62N8O7 694.9 Da Susceptible to enzymatic degradation; palmitoyl anchor reduces proteolytic cleavage rate compared to unmodified peptide Enhanced topical penetration via palmitoyl lipid modification enabling membrane interaction and dermal delivery 221227-05-0 Protocols starting Under 10 ppm (<0.001%) in finished product Once or twice daily Ongoing Customary leave-on cosmetic use is below 10 ppm of active peptide [6]. Pal-GHK is the signal-peptide core of the Matrixyl 3000 blend and is typically paired with Pal-GQPR. standard Up to ~0.002% in finished product Upper end of reported survey concentrations for leave-on products [6]. Even at this level the active peptide content is very low, which is normal for palmitoyl signal peptides. Customary leave-on cosmetic use is below 10 ppm of the active peptide [6]. Pal-GQPR is almost always used as a co-active alongside Pal-GHK in the Matrixyl 3000 blend rather than on its own. ~3% trade solution (Matrixyl 3000 blend) Twice daily ~2 months In manufacturer clinical testing the trade-solution blend was applied twice daily for about two months [6]. The ~3% figure refers to the diluted trade solution, which contains only ppm-level active peptide.
