Epitalon vs GHK-Cu (Copper Peptide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Epitalon
Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.

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 | Epitalon | GHK-Cu (Copper Peptide) |
|---|---|---|
| Mechanism | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. | 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. |
| Typical Dosage | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. | Topical: Applied as serum or cream 1-2 times daily. Injectable: 1-2mg daily for research purposes. Microneedling protocols often use 0.5-1%. |
| Administration | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. | Most commonly used topically for skin applications. Can be injected subcutaneously for systemic effects. Often combined with microneedling for enhanced skin penetration. |
| Side Effects | Generally well-tolerated. May affect sleep patterns initially. | Topical use is generally well-tolerated. May cause temporary skin irritation or redness in sensitive individuals. Injectable use may cause injection site reactions. |
