Copper Peptides vs Melanotan-1
A side-by-side research comparison of Copper Peptides and Melanotan-1 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Copper Peptides | Melanotan-1 |
|---|---|---|
| Full name | Copper Peptide Complex (AHK-Cu, GHK-Cu variants) | Melanotan-1 (Afamelanotide) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Approved (afamelanotide) / 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. | Selectively activates the melanocortin-1 receptor (MC1R) on melanocytes, increasing eumelanin production and providing UV photoprotection and skin darkening. |
| Molecular weight | 340-410 Da (varies) | 1646.85 Da |
| Half-life | 2-4 hours | ~1 hour (peptide); implant form is sustained |
| Bioavailability | High (topical penetration) | Subcutaneous injection or sustained-release implant |
| Typical dose | 1-3% topical solution | ~0.5-1 mg per dose (research) |
| Frequency | 1-2x daily | Daily loading then maintenance |
| Route | Topical | Subcutaneous injection |
