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 Semax is effective at it. Converting a dose does not make the dose validated. See the graded evidence on the Semax profile before relying on any figure here.

Ranges are reported from the literature for research context only. They are not a protocol and not a recommendation.
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.
