GHK-Cu Topical vs PTD-DBM
A side-by-side research comparison of GHK-Cu Topical and PTD-DBM across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | GHK-Cu Topical | PTD-DBM |
|---|---|---|
| Full name | GHK-Cu Copper Peptide (Topical/Scalp) | PTD-DBM (Wnt Pathway Hair Peptide) |
| Category | Hair Growth | Hair Growth |
| Status | Cosmetic / Research compound | Research peptide (topical) |
| 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). | PTD-DBM disrupts the interaction between CXXC5 and Dishevelled, releasing a natural brake on the Wnt/beta-catenin signaling pathway. Enhanced Wnt signaling promotes hair follicle neogenesis and regeneration. |
| Molecular weight | 403.92 Da (with Cu) | ~ (short cell-penetrating peptide) |
| Half-life | ~2-4 hours (topical depot at scalp) | Topical (local action) |
| Bioavailability | Topical penetration to dermal papilla | Topical (local delivery) |
| Typical dose | 1-2 mg/mL in scalp solution or serum | Topical scalp application (research) |
| Frequency | Daily application | Daily |
| Route | Topical scalp serum or mesotherapy injection | Topical |
