This comparison does not assign a generated winner or score.
- Tissue Repair Standard
- 5–10mg 2×/week (loading), 2–5mg weekly (maintenance)
- 8–12 weeks loading, 12+ weeks maintenance
- Subcutaneous injection
- Systemic tissue repair support, follicular angiogenesis as secondary effect
- Borrowed from soft tissue protocols. Not hair-specific
- Localized Scalp Injection
- 0.5–2mg per session, weekly
- 12–24 weeks minimum
- Intradermal scalp injection
- Targeted dermal papilla vascularization, reduced systemic distribution
- Theoretically sound but lacks clinical validation
- Topical + Microneedling
- Topical solution (concentration varies), applied post-needling
- 6–12 months
- 0.5–1.5mm microneedling + topical peptide
- Enhanced dermal penetration, localized VEGF upregulation
- Absorption rates unquantified. Mechanism plausible
- Combined DHT Blockade + TB-500
- 2–5mg TB-500 weekly + finasteride 1mg daily or topical minoxidil 5%
- 9–12 months
- Subcutaneous TB-500, oral finasteride, topical minoxidil
- Addresses both DHT-driven miniaturization and vascular insufficiency
- Most comprehensive but expensive and multi-variable
