Copper Peptides vs GHK (Basic)
A side-by-side research comparison of Copper Peptides and GHK (Basic) across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Copper Peptides | GHK (Basic) |
|---|---|---|
| Full name | Copper Peptide Complex (AHK-Cu, GHK-Cu variants) | GHK (Glycyl-L-Histidyl-L-Lysine, Copper-Free) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Cosmetic research peptide |
| Mechanism | Copper peptides deliver bioavailable copper to tissues while the peptide provides signaling to stimulate collagen I/III synthesis, attract immune cells for remodeling, and promote glycosaminoglycan production. | GHK is a matrikine signal peptide that resets gene expression toward tissue repair, stimulating collagen, elastin, and glycosaminoglycan synthesis and modulating antioxidant and anti-inflammatory pathways. It readily binds copper to become GHK-Cu in situ. |
| Molecular weight | 340-410 Da (varies) | 340.4 Da |
| Half-life | 2-4 hours | Short (peptide) |
| Bioavailability | High (topical penetration) | Topical (local); injectable (research) |
| Typical dose | 1-3% topical solution | Topical serum (~1-3 mg/mL) |
| Frequency | 1-2x daily | 1-2x daily |
| Route | Topical | Topical |
