TB-500 reconstitution calculator
Reconstitution calculator for TB-500, prefilled for 5 mg and 10 mg vials. Work out the concentration, the dose volume in millilitres, and the reading on a U-100 insulin syringe.
Start from a compound
Fills the vial size and a starting water volume. Only compounds with a citable range fill a dose.
The second is the question asked once the syringe is already filled, or when checking a vial someone else reconstituted.
1 mg = 1,000 mcg. Published figures are usually micrograms; vial labels are milligrams.

Animal studies exist but none establishes a human dose, and no human pharmacokinetic study could be cited.
Vial size and water volume are a starting point for the arithmetic, not a recommendation.
Adding more water makes the same dose a larger, easier-to-read mark on the syringe. It does not change how many doses the vial holds.
Vial sizes and starting volume
TB-500 is commonly supplied in 5 mg and 10 mg vials. The calculator opens on a 5 mg vial with 2 mL of bacteriostatic water — a starting point for the arithmetic, not a recommendation. Change either and everything recalculates.
That combination gives 2.5 mg/mL, so one insulin unit holds 25 mcg.
What dose to enter
No dose is prefilled for TB-500, because no range for it could be cited.
Animal studies exist but none establishes a human dose, and no human pharmacokinetic study could be cited.
The calculator still converts whatever figure you enter into a volume and a syringe reading — that arithmetic does not depend on the dose being a good one.
