TB-500 Dosage Calculator
A synthetic fragment related to Thymosin Beta-4, studied for recovery and flexibility research.
Total amount printed on the vial label.
Changes concentration only — your dose stays the same.
2500 mcg = 2.5 mg
1 mL barrels are sold marked two ways: 0–100 insulin units (U-100) or 0–1 mL (tuberculin / luer). Same volume — 100 units = 1 mL — so the result below gives you both readings.
1.0 mL (100-unit) · top row = insulin units, bottom row = mL · smallest mark = 2 units · check yours, gradations vary by brand
Show the math — every step, with your numbers
- Concentration: 5 mg ÷ 2 mL = 2.50 mg/mL (2500 mcg/mL)
- Dose volume: 2500 mcg ÷ 2500 mcg/mL = 1.000 mL
- Syringe units: 1.000 mL × 100 = 100 units
How much water should I add?
The same 2500 mcg dose from your 5 mg vial, at each water volume. More water spreads the dose over more units, which is easier to read accurately. Tap a row to use it.
✓ = the draw lands exactly on a mark of your 1.0 mL (100-unit) syringe — no eyeballing between gradations.
Calculated on a U-100 insulin syringe (100 units = 1 mL). This is reconstitution arithmetic for TB-500, not a dosing recommendation. Verify against your product label and a qualified professional.

Concentration for each vial size when reconstituted with 2 mL of bacteriostatic water. Change the water amount in the calculator to see other concentrations, or open the full reconstitution chart to compare every dose and water volume at once.
| Vial size | Bac. water | Concentration | Per unit (0.01 mL) |
|---|---|---|---|
| 2 mg | 2 mL | 1.00 mg/mL | 10.0 mcg |
| 5 mg | 2 mL | 2.50 mg/mL | 25.0 mcg |
| 10 mg | 2 mL | 5.00 mg/mL | 50.0 mcg |
About TB-500 dosing
TB-500 (TB-500) is a synthetic fragment related to Thymosin Beta-4, studied for recovery and flexibility research. It is commonly sold in 2 mg, 5 mg, 10 mg vials. Commonly-cited community and research protocols reference a range of 1,000–5,000 mcg, often dosed a few times per week in cited protocols. Higher microgram doses than BPC-157; a larger bac water volume makes the draw easier to read.
Remember that the number of syringe units for any dose depends entirely on how much bacteriostatic water you add. The calculator above is pre-filled with a common setup for TB-500; adjust the inputs to match your own vial and the units update instantly.

TB-500 calculator — FAQ
How do I reconstitute TB-500?+
Higher microgram doses than BPC-157; a larger bac water volume makes the draw easier to read. Add your chosen amount of bacteriostatic water to the vial, swirl gently (never shake), and use the calculator above to convert your target dose into insulin-syringe units.
What is a common TB-500 dose?+
Commonly-cited protocols reference 1,000–5,000 mcg, often dosed a few times per week in cited protocols. These are references for the arithmetic, not a prescription — confirm with your product label and a qualified professional.
How many units of TB-500 should I draw?+
That depends on your vial size and how much bacteriostatic water you added. Enter both into the calculator above along with your dose and it shows the exact units on a U-100 insulin syringe.
