Enter your Semax vial size and the volume of bacteriostatic water you are adding. The calculator returns the concentration in mcg/ml and the exact units to draw on a U-100 insulin syringe. It works for the common 5mg, 10mg and 30mg vials, whether you use Semax subcutaneously or intranasally.

How this is calculated
10mg × 1,000 = 10000 mcg total
10000 ÷ 2ml = 5000 mcg/ml
600 mcg ÷ 5000 = 0.12 ml
0.12 ml × 100 = 12 units

Semax is a peptide researched for cognition and neuroprotection, used both subcutaneously and intranasally in the low-microgram range. The reconstitution concentration (mcg/ml) applies regardless of route — it simply tells you how strong each millilitre of your solution is.
Ranges commonly reported in research use. Semax is frequently used intranasally, in which case the concentration figure tells you the strength per drop or spray.
| Common dose | 300–600 mcg per administration |
| Typical frequency | once or twice daily |
Worked example: 10mg vial + 2ml BAC water, 600mcg dose
2ml gives 5,000 mcg/ml, so a 600mcg dose is 0.12ml = 12 units. For intranasal use, the same concentration tells you how many mcg are in each drop or measured spray.
With a 10mg vial reconstituted in 2ml (5,000 mcg/ml): 600 ÷ 5,000 = 0.12ml = 12 units. A 300mcg dose at the same concentration is 6 units.
Yes. It gives the concentration in mcg/ml, which applies however you administer the solution. For nasal use, divide that concentration across your drops or spray volume rather than drawing units on a syringe.
Refrigerate at 2–8°C away from light and label the vial with the date. Reconstituted Semax is commonly used within 2–4 weeks. Do not freeze it.
Store your vial concentration, log every dose against it, and never lose track of what you injected or when.
