Cortexin 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 5 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.

U-100 math for listed Cortexin sizes. Each cell is micrograms per syringe mark if you add that much liquid. The table does the same math as the calculator. It does not pick an amount for you.
| Listed vial | 1 mL liquid | 2 mL liquid | 3 mL liquid |
|---|---|---|---|
| 5 mg | 50 | 25 | 16.7 |
| 10 mg | 100 | 50 | 33.3 |
Other names in the library: Cortexin 10mg — 10mg / Premium, Cortexin 10mg — 5mg (Out of stock) / Premium. Evidence describes the named substance, not a quality certification or equivalence assessment of commercial stock. Listed sizes: 5 mg, 10 mg. A seller title is a listing. It does not prove the vial matches a paper.
Named peptide-extract preparation; a heterogeneous extract is not a single defined peptide.

The calculator turns numbers you type into U-100 units. Trial or label amounts stay as cited facts.
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.
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.
