GHK-Cu (Copper Peptide) vs Epigen
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
GHK-Cu (Copper Peptide)
GHK-Cu is a naturally occurring copper peptide found in human plasma, saliva, and urine. It plays important roles in wound healing, tissue repair, and has shown anti-aging properties in research.

| Aspect | GHK-Cu (Copper Peptide) | Epigen |
|---|---|---|
| Mechanism | Attracts immune cells and fibroblasts to wound sites, stimulates collagen and glycosaminoglycan synthesis, promotes angiogenesis, and has antioxidant effects. Modulates gene expression related to tissue repair. | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. |
| Typical Dosage | Topical: Applied as serum or cream 1-2 times daily. Injectable: 1-2mg daily for research purposes. Microneedling protocols often use 0.5-1%. | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. |
| Administration | Most commonly used topically for skin applications. Can be injected subcutaneously for systemic effects. Often combined with microneedling for enhanced skin penetration. | Primarily topical application for skincare. Research may use other routes for systemic effects. |
| Side Effects | Topical use is generally well-tolerated. May cause temporary skin irritation or redness in sensitive individuals. Injectable use may cause injection site reactions. | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. |
