How to Use TB-500 for Hair Growth Protocol: Dosing Comparison
Loading Phase 5mg Twice weekly (e.g., Mon/Thu) Weeks 1–8 Vellus hair appearance, increased scalp circulation, reduced shedding Necessary to saturate tissue receptors and establish baseline angiogenesis. Skipping this phase delays visible results by 4–6 weeks M

- Loading Phase
- 5mg
- Twice weekly (e.g., Mon/Thu)
- Weeks 1–8
- Vellus hair appearance, increased scalp circulation, reduced shedding
- Necessary to saturate tissue receptors and establish baseline angiogenesis. Skipping this phase delays visible results by 4–6 weeks
- Maintenance Phase
- 2–3mg
- Twice weekly
- Weeks 9–24
- Transition from vellus to terminal hair, continued thickness improvement
- Lower dose sustains angiogenic signaling without excessive cost. Most users see peak thickness at 20–24 weeks
- Post-Protocol Retention
- 2mg
- Once weekly or biweekly
- Ongoing (optional)
- Prevents regression to baseline follicle state
- Not required if finasteride or minoxidil are continued, but useful for users who can't tolerate oral DHT blockers
- Microneedling + TB-500
- 2–5mg
- Twice weekly (12–24 hours post-microneedling)
- Weeks 1–24
- Enhanced localized uptake, faster vellus-to-terminal transition
- Microneedling amplifies receptor upregulation. This combination produces faster visible results than TB-500 alone in our experience
