PNC-28 calculator
PNC-28 math uses the listed vial sizes on this card and the liquid you type. Concentration in mcg per mL is vial milligrams times 1000, divided by milliliters. A U-100 syringe has 100 marks per milliliter, so each unit is that concentration divided by 100. Example numbers so you can see the math: a 10 mg listing plus 2 mL of liquid. Change any number and the units change. Try the numbers. A research-market vial is not the same material used in a trial.

Questions people ask
Is PNC-28 FDA-approved?
not established. No approval for this exact marketed preparation or claimed wellness indication is established in this source set.
Does PepBear pick an amount of PNC-28?
The calculator turns numbers you type into U-100 units. Trial or label amounts stay as cited facts.
How many units is a listed PNC-28 vial after you add water?
Units = (amount in mcg ÷ (vial mg × 1000 ÷ water mL)) × 100 on a U-100 syringe. Enter the three numbers. The chart shows the same math for each listed vial size and 1, 2 or 3 mL of liquid.
Why flag amounts under 5 units?
A U-100 barrel is easy to misread below about 5 marks. That is a measuring warning. The page does not tell you to take more.
