TB-500 Dosage Calculator
TB-500 has no established human dosing regimen in the reference evidence used here. This calculator demonstrates milligram-to-volume arithmetic only. Research on full-length thymosin beta-4 does not automatically establish the identity, effects, or safety of a product sold as TB-500.
This is a unit converter. It converts an amount you already have into volume and syringe units. It does not tell you what to take, and it is educational only — not medical advice. Confirm every amount with your clinician and your product label.
Example mixes to try the converter
Examples only — not recommended amounts. These fill in a vial size and diluent volume only — never an amount to inject. Enter the dose your clinician gave you yourself.

TB-500 concentration reference (mg/mL)
What each vial size becomes at common bacteriostatic water volumes.
| Vial | + 1 mL | + 2 mL | + 3 mL | + 5 mL |
|---|---|---|---|---|
| 2 mg | 2.00 mg/mL | 1.00 mg/mL | 0.67 mg/mL | 0.40 mg/mL |
| 5 mg | 5.00 mg/mL | 2.50 mg/mL | 1.67 mg/mL | 1.00 mg/mL |
| 10 mg | 10.00 mg/mL | 5.00 mg/mL | 3.33 mg/mL | 2.00 mg/mL |
TB-500 dosing evidence
No established, regulator-approved human dosing range. DoseRoutine performs arithmetic; it does not choose or recommend a dose. Your prescriber decides yours.
No single dosing table is shown because an established human range is unavailable or depends on the exact approved indication and product label.

What trips people up
- 5 mg + 2 mL = 2.5 mg/mL, so a 2 mg dose is 80 units — most of a U-100 syringe.
- U-100 means 100 markings per milliliter, not a universal syringe capacity. Check the device capacity; an oversized result is not an instruction to split an injection or change a preparation.
- A reliable human TB-500 half-life and injection schedule are not established by this reference. Do not infer them from full-length thymosin beta-4 experiments or seller claims.
- Blended BPC-157/TB-500 vials must be calculated per peptide — the label weight is the sum of both.
How the math works
- Concentration (mg/mL) = vial mg ÷ bacteriostatic water mL.
- Volume per dose (mL) = dose mg ÷ concentration.
- Syringe units = volume × 100 on a U-100 syringe, or × 40 on a U-40 syringe.
- Doses per vial = vial mg ÷ dose mg. Water volume never changes this number.
TB-500 calculator FAQ
How much BAC water for a 5 mg TB-500 vial?
There is no established clinical mixing standard provided here. As hypothetical arithmetic, 5 mg divided by 2 mL equals 2.5 mg/mL. That calculation does not establish an appropriate diluent, a safe preparation, or a human dose.
How many units is 2 mg of TB-500?
At 2.5 mg/mL it is 0.8 mL = 80 units on a U-100 syringe. At 5 mg/mL (5 mg + 1 mL) the same dose is 40 units.
How often should TB-500 be injected?
No evidence-backed human injection frequency is established here. Loading and maintenance schedules circulated online should not be presented as clinical guidance; the calculator cannot determine frequency or duration.
Can TB-500 and BPC-157 go in the same syringe?
This calculator does not establish compatibility, sterility, or safety of combining products in one syringe. A blended label also needs separate quantities for each ingredient; a total blend weight alone cannot determine the concentration of either compound.
Educational tool only — not medical advice. Verify every dose with your prescriber and follow sterile technique. See our medical disclaimer.
