PTD-DBM vs TB-4 Topical (Hair)
A side-by-side research comparison of PTD-DBM and TB-4 Topical (Hair) across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | PTD-DBM | TB-4 Topical (Hair) |
|---|---|---|
| Full name | PTD-DBM (Wnt Pathway Hair Peptide) | Thymosin Beta-4 Topical (Hair Growth) |
| Category | Hair Growth | Hair Growth |
| Status | Research peptide (topical) | Research compound |
| Mechanism | 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. | Promotes migration and differentiation of hair follicle stem cells via actin sequestration and cell motility enhancement. Activates quiescent stem cells in the bulge niche. Stimulates new blood vessel formation around follicles for nutrient delivery. |
| Molecular weight | ~ (short cell-penetrating peptide) | 4921 Da |
| Half-life | Topical (local action) | ~6 hours (systemic); local depot effect (topical) |
| Bioavailability | Topical (local delivery) | Topical: penetrates to bulge region with microneedling |
| Typical dose | Topical scalp application (research) | 50-200 mcg per scalp application or 0.1% solution |
| Frequency | Daily | 3x weekly |
| Route | Topical | Topical serum or mesotherapy (intradermal injection) |
