Calculator
Reconstitution math that remembers.
Calculate units on an insulin syringe from peptide amount, BAC water, and target dose — or work backwards from how many units you want each pin to be.
I know my vial. How many units do I draw?

The math, explained.
01
Concentration
mg ÷ mL
Divide the peptide mass on the vial label by the BAC water you added. That gives you mg/mL — the concentration of the reconstituted solution.
02
Volume per dose
dose ÷ concentration
Convert your target dose to mg (mcg ÷ 1000), then divide by the concentration. The result is the volume in mL you draw for one injection.
03
Units on syringe
mL × 100
U-100 insulin syringes are calibrated so 100 units = 1 mL. Multiply your draw volume by 100 to get the unit mark on the barrel.
Why we show all three: every step is somewhere the user has to verify. If the calculator hides the intermediate math, you have no way to sanity-check whether the final number is right. We surface it on purpose.
