TB-500 Calculator
Open a math-only TB-500 calculator page for vial, BAC water, concentration, and U-100 syringe marks.
Math support only
This page is for calculator math and education. It does not diagnose, prescribe, or replace product-label or prescriber instructions.Important safety limit
FDA's April 22, 2026 503A update says TB-500 was removed from category 2 because the nomination was withdrawn and that PCAC consultation is planned for July 23, 2026. This page does not say TB-500 is approved or appropriate for use.
Why it can rank
TB-500 calculator and TB-500 reconstitution searches are high-intent because users are usually trying to translate vial math into syringe marks.
Frequently asked questions
Does this recommend a TB-500 dose?
No. It opens editable calculator math only. Dose, route, timing, and whether a product is appropriate must come from the product label, pharmacy, or licensed prescriber.
Can I use this for research-only products?
The calculator only handles measurement math. It does not decide whether a product is legal, approved, safe, sterile, or appropriate for human use.
Is this a prescription or protocol?
No. PeptiCalc is a measurement calculator. It helps translate vial strength, BAC water, and a selected dose into syringe marks, but it does not prescribe treatment.
Can I edit the preloaded values?
Yes. Every value that opens in the calculator is editable, including vial amount, BAC water, syringe size, and dose.
Why do syringe marks matter?
Most U-100 insulin syringes show 100 marks per mL. The calculator converts the liquid dose into the mark to pull to on that syringe scale.
