Epigen vs Palmitoyl Tetrapeptide-7
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Epigen
Epigen is a member of the epidermal growth factor (EGF) family. It plays roles in skin regeneration and has been studied for wound healing and anti-aging applications.
Full details →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 | Epigen | Palmitoyl Tetrapeptide-7 |
|---|---|---|
| Dose Range | 100 mcg–500 mcg | 500 mcg–2 mg |
| Frequency | 1x daily | 2x daily |
| Cycle Length | 4–8 weeks | 4–12 weeks |
| Route | subcutaneous | topical |
| Mechanism | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. | Suppresses interleukin-6 (IL-6) production, reducing inflammation that contributes to skin aging. The anti-inflammatory effect complements collagen-stimulating peptides. |
| Typical Dosage | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. | Topical: Usually combined with Palmitoyl Tripeptide-1 at similar concentrations (2-4%) in the Matrixyl 3000 complex. |
| Administration | Primarily topical application for skincare. Research may use other routes for systemic effects. | Topical application with other anti-aging actives. The palmitoyl group enhances delivery into the skin. |
| Side Effects | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. | Excellent tolerability profile. Anti-inflammatory properties may actually soothe sensitive skin. |
