TB-500 (5mg Vial) Dosage Protocol
TB-500 is a synthetic peptide fragment that copies the active region (Ac-LKKTETQ) of Thymosin Beta-4, a naturally occurring protein involved in cell migration and tissue repair. It is referenced as a once-daily subcutaneous injection dosed in micrograms with gradual titration. There are no completed human efficacy trials of the TB-500 fragment; presented for research and educational purposes only.
Synthetic fragment of Thymosin Beta-4; preclinically linked to actin regulation, cell migration and angiogenesis. No completed human efficacy trials of the fragment.
Once-daily subcutaneous injection, titrated from ~500 mcg to ~1000 mcg/day (about ~5 mg per week).
3 mL bacteriostatic water per 5 mg vial gives ~1.67 mg/mL for accurate insulin-syringe dosing.
Freeze the lyophilized vial; refrigerate the reconstituted solution and do not freeze it.

Dosing & Reconstitution Guide
A single practical dilution with accurate once-daily dosing, step by step
Standard / Gradual Approach (3 mL = ~1.67 mg/mL)
Reconstitute: Add 3.0 mL bacteriostatic water to one 5 mg vial → final concentration ~1.67 mg/mL (1,667 mcg/mL).
Typical daily range: 500–1000 mcg once daily, raised gradually over an 8–12 week course.
Easy measuring: At ~1.67 mg/mL, 1 unit ≈ 16.7 mcg on a U-100 syringe. Using the large 3.0 mL dilution keeps every dose at 30 units or more for excellent measuring accuracy.
Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the mixed solution.
