T-02
TB-500 syringe unit and mass converter
Two-way conversion between mg, mcg, mL and U-100 insulin syringe units at a given concentration.
A converter for the moment you have a concentration and need the other three numbers. It performs no validation of whether a value is sensible for a person, because no source establishes what sensible would mean for this compound.
Result
Enter a value to convert.
Worked example
At 2.5 mg/mL, converting 10 units gives 0.1 mL, which is 250 mcg. The restatement reads: at 2.5 mg/mL, 10 units on a U-100 syringe is 0.1 mL, containing 250 mcg.
Step by step
- Enter the concentration you computed in T-01, or read it from your own documentation.
- Choose a conversion direction.
- Enter the value to convert and read the result, with a plain-language restatement beneath it.
Frequently asked questions
Why does the same unit count mean different masses?
Because units are volume, not mass. Ten units is always 0.1 mL; how much peptide sits in that 0.1 mL is set entirely by how much water you added to the vial.
Does this convert animal doses to human doses?
No, and it never will. Published TB-500 doses are 60 ug/kg/day in rats and 10 mg subcutaneously in horses; full-protein human doses are in milligrams intravenously or in topical percentages. No validated conversion exists between any of them.
