TB-500 Dosage Calculator
TB-500 is a synthetic peptide related to a fragment of thymosin beta-4, studied in animal models of cellular migration and tissue repair. It is an investigational research compound and is not FDA-approved.
Enter the milligrams on your vial, the bacteriostatic water you are adding, and your dose in micrograms. Because TB-500 doses are relatively large (often in the low milligrams), a larger water volume keeps the draw comfortably readable on a U-100 insulin syringe.
The TB-500 dosage chart shows how commonly-referenced dose points translate to a draw at your vial size and water volume. Every figure is illustrative arithmetic, not a recommendation.
Tip: adding 0.50 mL of bacteriostatic water would put this dose on a clean, easy-to-read mark on a U-100 insulin syringe.

TB-500 Dosage Chart
Commonly-cited dose points (commonly-cited research range) at a 5 mg vial reconstituted with 2 mL of bacteriostatic water. The volume and syringe columns are computed from those inputs — illustrative math, never a dose recommendation.
| Example dose | Volume to draw | U-100 syringe | Notes |
|---|---|---|---|
| 1 mg (1,000 mcg) | 0.400 mL | 40 IU | — |
| 2 mg (2,000 mcg) | 0.800 mL | 80 IU | commonly-cited loading figure |
| 2.5 mg (2,500 mcg) | 1.000 mL | 100 IU | — |
How to use this calculator
- Vial size — the milligrams printed on your TB-500 vial (commonly 5 or 10 mg).
- Bacteriostatic water — how much you add to dissolve the powder. More water = a larger, easier-to-read draw at the same dose.
- Dose — the amount you intend to draw, in micrograms. This is your number, not a recommendation.
- Read the IU mark — on a U-100 insulin syringe, 1 IU = 0.01 mL. The calculator shows the exact tick to fill to.
TB-500 FAQ
- How do I reconstitute TB-500?
- Add bacteriostatic water down the wall of the vial and let the powder dissolve without shaking. Use the calculator above to see the resulting concentration and the exact U-100 insulin-syringe mark for your dose.
- How many units is a 2 mg TB-500 dose?
- It depends on your concentration. A 5 mg vial reconstituted with 2.5 mL yields 2,000 mcg/mL, so a 2,000 mcg (2 mg) draw is 1.0 mL, which is 100 IU — the full length of a 1 mL U-100 syringe. Adjust water volume to land on a comfortable mark.
- Is the TB-500 dosage chart a recommendation?
- No. It lists commonly-cited research figures only to illustrate the reconstitution math. It is educational, not medical advice, and not a dose recommendation.
- How is reconstituted TB-500 stored?
- Reconstituted peptide is generally refrigerated (about 2–8 °C) and protected from light; the dry powder is kept frozen. Follow the storage guidance for your specific product.
