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.
Mechanism of Action
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 (Research)
Topical: Applied as serum or cream 1-2 times daily. Injectable: 1-2mg daily for research purposes. Microneedling protocols often use 0.5-1%.
Most commonly used topically for skin applications. Can be injected subcutaneously for systemic effects. Often combined with microneedling for enhanced skin penetration.
Considerations for Men & Women
Women: Copper peptide widely used in skincare. Topical use has no sex-specific differences — stimulates collagen, improves skin elasticity, and promotes wound healing equally. Injectable form may have different effects — women's skin is generally thinner and may respond more visibly to collagen stimulation.
Men: Same collagen-stimulating and wound-healing benefits. Thicker male skin may require longer treatment periods for visible cosmetic results. Injectable protocols are the same for both sexes.
Individual responses vary. These notes reflect general trends from research literature and are not medical advice.
