TB-500 dosage calculator
Calculate your TB-500 reconstitution volume, dose per injection, and how long your supply will last. Enter your vial size and desired dose below.
Reconstituting a 5 mg vial of TB-500 with 2 mL of bacteriostatic water gives a concentration of 2500 mcg/mL. At that concentration a 2500 mcg dose is 1.000 mL, which is 100.0 units on a U-100 insulin syringe, and one vial yields 2 doses of that size. Change the vial size, water volume or target dose and the arithmetic changes — the table below covers the common doses, and the calculator handles any combination.

Common doses at a glance.
Every row assumes a 5 mg vial reconstituted with 2 mL of bacteriostatic water, drawn on a U-100 syringe.
| Dose | Volume | Draw to | Doses per vial |
|---|---|---|---|
| 500 mcg | 0.200 mL | 20.0 U | 10 |
| 1000 mcg | 0.400 mL | 40.0 U | 5 |
| 2000 mcg | 0.800 mL | 80.0 U | 2 |
| 2500 mcg | 1.000 mL | 100.0 U | 2 |
How the arithmetic works.
- conc = 5 mg ÷ 2 mL = 2500 mcg/mL
- vol = 2500mcg ÷ 2500 = 1.000 mL
- units = 1.000 mL × 100 = 100.0 U
A U-100 syringe is graduated so that 100 units equals 1 mL, which is why the volume in millilitres is multiplied by 100 to get the mark to draw to.
This tool does unit arithmetic and nothing else. It does not know your body weight, bloodwork, medication interactions or tolerance, and it does not recommend a dose — the dose you enter is the dose you chose. It assumes a U-100 syringe and full dissolution of the compound, and it cannot account for measurement error, product purity, or a vial that was under-filled. PeptideIQ does not sell, prescribe, or recommend research compounds. Reconstitution math is provided for educational reference. Dosing decisions are between you and a licensed clinician.
