A range exists, but the evidence is preliminary
The range above is what studies or protocols have used, but no human trial has established that Cortexin is effective at it. Converting a dose does not make the dose validated. See the graded evidence on the Cortexin profile before relying on any figure here.

Concentration by vial and diluent
| Vial | 1 mL diluent | 2 mL diluent | 3 mL diluent |
|---|---|---|---|
| 2 mg | 2,000 mcg/mL | 1,000 mcg/mL | 667 mcg/mL |
| 5 mg | 5,000 mcg/mL | 2,500 mcg/mL | 1,667 mcg/mL |
| 10 mg | 10,000 mcg/mL | 5,000 mcg/mL | 3,333 mcg/mL |
Concentration is vial mass divided by diluent volume. Reconstitution volume changes what you draw, never the dose itself.
