Arithmetic, not a recommendation

This page does not select a BAC-water amount, target amount, treatment, schedule, product, or method of administration. Confirm the exact product instructions and all values independently.

Selank 5 mg and 10 mg reconstitution calculator

Enter the total quantity printed on the vial and an amount you want to measure. The default mode compares mathematically workable BAC-water volumes.

Selank reconstitution calculator and chart

Use this page to compare reconstitution math for 5 mg, 10 mg vials. It calculates concentration, liquid volume, and a corresponding U-100 syringe mark for values you enter.

Arithmetic only: the chart does not select a BAC-water volume, dosage, schedule, product, or preparation method.

How to use the calculator

  • Enter the complete vial quantity and choose mg or mcg to match the label.
  • Enter an amount to convert; the website does not recommend this value.
  • Compare the concentration, liquid volume, and syringe mark for each BAC-water option.
  • Verify the label, diluent instructions, and syringe type independently.

Reading the reconstitution chart

Changing the liquid volume changes concentration. More liquid produces a lower mathematical concentration and a larger liquid volume for the same entered amount; less liquid does the reverse. This page calculates vial-and-liquid arithmetic only and does not cover nasal formulations or preparation methods.

Frequently asked questions

Can I use this for 5 mg or 10 mg vials?

Yes. Enter the matching number and unit from the label. The same formula is applied to every supported vial amount.

How much BAC water should be added?

The calculator compares volumes but does not choose one. Follow the exact product instructions and qualified professional guidance.

Is this a dosage calculator?

No. It performs concentration and liquid-volume arithmetic using visitor-entered values. It does not recommend treatment or dosing.

Transparent formula

How the calculator works

1

Concentration

vial amount in mg ÷ BAC water in mL

The result is shown in mg/mL, with mcg/mL as a secondary conversion.

2

Liquid volume

amount entered in mg ÷ concentration in mg/mL

This determines the liquid volume containing the amount entered.

3

U-100 syringe mark

liquid volume in mL × 100

The scale comparison applies only to a correctly identified U-100 syringe.

Product-specific context

Numbers cannot verify the product

A correct calculation cannot establish identity, purity, sterility, stability, compatibility, regulatory status, or suitability. Product labeling and qualified professional guidance control over a generic calculator.
