Semax Nasal Spray Calculator
Semax is a synthetic peptide developed in Russia, commonly used intranasally. This page shows how to reconstitute it and read the result on a syringe — the spray calculator does the arithmetic for you.
Status: Approved as a nasal medication in Russia; elsewhere it is sold as a research compound and is not approved.
The math
Per pump = (vial ÷ total volume) × pump volume
Semax is most often prepared as an intranasal solution. Use the spray calculator to find the micrograms delivered per pump from your mixed concentration.

Frequently asked questions
How do I calculate Semax dose per spray?
Add your bacteriostatic water and saline for the total volume, divide the Semax amount by that total to get the concentration, then multiply by the pump volume (commonly 0.1 mL). For a 30 mg vial in 3 mL total, that is 10 mg/mL, so each 0.1 mL pump delivers about 1,000 mcg.
What vial sizes does Semax come in?
Semax is commonly supplied as 5 mg, 10 mg, 30 mg. The amount in the vial does not change with how much water you add — water only sets the concentration.
Is Semax approved for human use?
Approved as a nasal medication in Russia; elsewhere it is sold as a research compound and is not approved. This calculator only performs arithmetic on the numbers you enter and does not recommend any dose.
