Argireline vs GHK-Cu
A side-by-side research comparison of Argireline and GHK-Cu across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Argireline | GHK-Cu |
|---|---|---|
| Full name | Argireline (Acetyl Hexapeptide-3) | Copper Peptide GHK-Cu (Glycyl-Histidyl-Lysine Copper) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| Mechanism | Competes with SNAP-25 for position in SNARE complex, partially inhibiting vesicle docking and neurotransmitter release, reducing muscle contraction intensity. | Copper delivery enhances antioxidant enzyme activity (SOD), stimulates collagen and glycosaminoglycan synthesis, promotes stem cell activation, and modulates gene expression. |
| Molecular weight | 889 Da | 403.93 Da |
| Half-life | 8-12 hours (topical) | ~2-4 hours |
| Bioavailability | Moderate (topical) | Topical: local; Injectable: ~90% subcutaneous |
| Typical dose | 5-10% solution | 1-3 mg topical · 200-500 mcg injectable |
| Frequency | 2x daily | Daily (topical) · 3x/week (injectable) |
| Route | Topical | Topical cream/serum or subcutaneous injection |
