What is TB-500?
TB-500 is a synthetic version of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino acid peptide found in virtually all human and animal cells. It plays a critical role in building new blood vessels, muscle tissue fibers, and cell migration and reproduction. Researchers study TB-500 for its potential in accelerating healing of wounds, tendons, ligaments, and muscle.
Research Dosing Parameters
- Typical dose range: 2–5 mg per week (2000–5000 mcg)
- Common vial size: 5 mg
- Reconstitution: 1–2 mL bacteriostatic water
- Injection frequency: 2x per week in loading phase research protocols
How to Reconstitute TB-500
- Use bacteriostatic water for reconstitution
- Inject slowly along the vial wall
- Gently swirl until the lyophilized powder is fully dissolved
- Do not shake — this can degrade the peptide
- Store at 2–8°C and use within 30 days
FAQ
Can TB-500 be stacked with BPC-157? TB-500 and BPC-157 are commonly studied together in research settings for synergistic healing effects. Use the multi-peptide feature in the calculator above to compute combined volumes.
How many units is 2mg of TB-500? This depends on your reconstitution volume. Enter 5mg vial + 2mL water + 2000mcg dose in the calculator to get exact units.
How long does TB-500 stay stable once reconstituted? Reconstituted TB-500 stored at 2–8°C is generally stable for up to 30 days.
