GHK-Cu Topical vs Minoxidil
A side-by-side research comparison of GHK-Cu Topical and Minoxidil across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | GHK-Cu Topical | Minoxidil |
|---|---|---|
| Full name | GHK-Cu Copper Peptide (Topical/Scalp) | Minoxidil (Rogaine) |
| Category | Hair Growth | Hair Growth |
| Status | Cosmetic / Research compound | FDA Approved (OTC) |
| Mechanism | Activates genes for hair growth including VEGF, FGF, and nerve growth factor at the follicular level. Stimulates dermal papilla cell proliferation. Extends anagen phase via Wnt/β-catenin pathway activation. Delivers copper for lysyl oxidase (collagen cross-linking). | Opens ATP-sensitive potassium channels in vascular smooth muscle and hair follicle cells. Increases blood flow and nutrient delivery to follicles. Prolongs anagen (growth) phase and stimulates VEGF expression for neovascularization around follicles. |
| Molecular weight | 403.92 Da (with Cu) | 209.25 Da |
| Half-life | ~2-4 hours (topical depot at scalp) | ~4 hours (systemic); active in follicle for 22h |
| Bioavailability | Topical penetration to dermal papilla | ~95% oral; topical: local depot effect |
| Typical dose | 1-2 mg/mL in scalp solution or serum | 5% topical (1mL 2x/day) or 2.5-5 mg oral |
| Frequency | Daily application | Twice daily (topical) or once daily (oral) |
| Route | Topical scalp serum or mesotherapy injection | Topical solution/foam or oral tablet |
