1. Read the current label
Enter the total Semax amount printed on the vial and the total liquid volume for that same vial. Do not combine values from two products.
This Semax calculation guide connects a clearly labeled vial amount, liquid volume, target mass, mL, and U-100 markings. It does not select a dose, schedule, route, or product.
Illustrative arithmetic · not dosing guidance
Every row is arithmetic based on 5 mg in 2 mL, producing a concentration of 2.5 mg/mL. This is not a mixing instruction. The target values are mathematical examples. They are not common, prescribed, or recommended doses.
| Example target | Volume at 2.5 mg/mL | U-100 marking |
|---|---|---|
| 250 mcg | 0.1 mL | 10 units |
| 500 mcg | 0.2 mL | 20 units |
| 1,000 mcg | 0.4 mL | 40 units |
These are mathematical examples only, not common or recommended Semax doses. Replace every value with instructions from a licensed professional and the current product label.
Three-step calculation
This page explains the calculation. The shared Peptide Calculator applies values you already have and never chooses a vial amount, liquid volume, target mass, or schedule.
Enter the total Semax amount printed on the vial and the total liquid volume for that same vial. Do not combine values from two products.
Use the CTA above to preselect Semax, then replace every illustrative value with the vial, liquid, and target values from your qualified source.
Read concentration first, then mL, then the U-100 marking. Repeat the decimal and unit conversion independently before relying on the result.
Product-specific context
Semax is discussed in nasal and other research-product contexts. A nasal concentration or spray actuation cannot be converted as though it were a U-100 injectable vial.
A Semax dosage calculator can only convert values that are already known. It cannot verify identity, purity, sterility, formulation, route, clinical suitability, or whether a product is lawful or approved.
U-100 syringe units describe liquid volume: 100 units equals 1 mL. The mass of Semax represented by that volume changes with concentration, so a unit value from another vial or source must never be copied.
Transparent arithmetic
The name does not change the equations. Concentration links mass to volume; the U-100 conversion is applied last.
vial mg ÷ liquid mL = mg/mLtarget mg ÷ mg/mL = mLdose mL × 100 = unitsIf the target is entered in mcg, divide by 1,000 before using the dose-volume formula. The linked calculator does this conversion internally while keeping both mass units visible in the result.
Before accepting a result
Do not apply vial arithmetic to a pen, tablet, capsule, ampoule, nasal product, or fixed-dose device unless its official instructions explicitly require that calculation.
Take the total mass and liquid volume from the same Semax product. Do not combine values from different sellers, batches, or formulations.
Milligrams and micrograms describe mass; milliliters and U-100 markings describe volume. Verify the 1,000-fold mg-to-mcg conversion independently.
