Palmitoyl Tetrapeptide-7 vs Dihexa
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Palmitoyl Tetrapeptide-7
Palmitoyl Tetrapeptide-7 is an anti-inflammatory peptide that reduces IL-6 secretion. Combined with Palmitoyl Tripeptide-1, it forms Matrixyl 3000, addressing both collagen production and inflammation.

| Aspect | Palmitoyl Tetrapeptide-7 | Dihexa |
|---|---|---|
| Mechanism | Suppresses interleukin-6 (IL-6) production, reducing inflammation that contributes to skin aging. The anti-inflammatory effect complements collagen-stimulating peptides. | Acts as a hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway. |
| Typical Dosage | Topical: Usually combined with Palmitoyl Tripeptide-1 at similar concentrations (2-4%) in the Matrixyl 3000 complex. | Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency. |
| Administration | Topical application with other anti-aging actives. The palmitoyl group enhances delivery into the skin. | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. |
| Side Effects | Excellent tolerability profile. Anti-inflammatory properties may actually soothe sensitive skin. | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. |
