Copper Peptides vs GHK-Cu
A side-by-side research comparison of Copper Peptides and GHK-Cu across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Copper Peptides | GHK-Cu |
|---|---|---|
| Full name | Copper Peptide Complex (AHK-Cu, GHK-Cu variants) | Copper Peptide GHK-Cu (Glycyl-Histidyl-Lysine Copper) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| 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. | Copper delivery enhances antioxidant enzyme activity (SOD), stimulates collagen and glycosaminoglycan synthesis, promotes stem cell activation, and modulates gene expression. |
| Molecular weight | 340-410 Da (varies) | 403.93 Da |
| Half-life | 2-4 hours | ~2-4 hours |
| Bioavailability | High (topical penetration) | Topical: local; Injectable: ~90% subcutaneous |
| Typical dose | 1-3% topical solution | 1-3 mg topical · 200-500 mcg injectable |
| Frequency | 1-2x daily | Daily (topical) · 3x/week (injectable) |
| Route | Topical | Topical cream/serum or subcutaneous injection |
