Units per dose at 200 mg/mL

Insulin syringes are graduated in hundredths of a millilitre, so units = mL × 100 on a U-100, U-50 or U-30 barrel alike.

How this is calculated

  1. 1 · Concentration

    1000 mg ÷ 5 mL = 200 mg/mL

    The peptide mass never changes — bacteriostatic water only sets how concentrated the solution is, and therefore how far the plunger travels.

  2. 2 · Volume for a 100 mg dose

    100 mg ÷ 200 mg/mL = 0.5 mL

  3. 3 · Insulin units

    0.5 mL × 100 = 50 units

    Every unit on the barrel carries 2000 mcg at this concentration, so misreading by one unit is a 2000 mcg error.

The interactive calculator draws this 200 mg/mL mix on a scaled U-100 barrel, shows when a draw lands exactly on a printed tick, and works backwards from a target dose to the water volume that makes it land cleanly.

Common questions

How much bacteriostatic water for a 1000 mg NAD+ vial?
Adding 5 mL of bacteriostatic water to a 1000 mg NAD+ vial yields 200 mg/mL — 2000 mcg in every insulin unit. The reconstituted vial holds 500 units of solution in total.
How many units is a 100 mg dose of NAD+ at 1000 mg in 5 mL?
100 mg is 0.5 mL of this mix, which is 50 units on a U-100 insulin syringe (a U-50 barrel is enough).
How many 100 mg doses does a 1000 mg vial give?
A 1000 mg vial contains 10 full 100 mg doses. Using more or less bacteriostatic water changes the units you draw, never the number of doses in the vial.
