Lactoferricin vs GHK-Cu (Copper Peptide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Lactoferricin
Lactoferricin is an antimicrobial peptide derived from lactoferrin, a protein found in milk and other secretions. It has potent antibacterial, antiviral, and antifungal properties.

| Aspect | Lactoferricin | GHK-Cu (Copper Peptide) |
|---|---|---|
| Mechanism | Binds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects. | 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 applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily. | 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 | Available through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings. | Most commonly used topically for skin applications. Can be injected subcutaneously for systemic effects. Often combined with microneedling for enhanced skin penetration. |
| Side Effects | Lactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies. | Topical use is generally well-tolerated. May cause temporary skin irritation or redness in sensitive individuals. Injectable use may cause injection site reactions. |
