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.

HCG reconstitution calculator using IU
Enter the total quantity printed on the vial and an amount you want to measure. The default mode compares mathematically workable BAC-water volumes.
HCG (Research) reconstitution calculator and chart
Use this page to compare reconstitution math for the amount printed on the vial. 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 IU for both quantity fields.
- 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. Use IU for both quantity entries. IU and mg or mcg are different dimensions and the calculator intentionally prevents converting between them.
Frequently asked questions
Can I enter the exact quantity from my vial?
Yes. Enter the total quantity and unit exactly as printed on the label.
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.

How the calculator works
Liquid volume
amount entered in IU ÷ concentration in IU/mLThis determines the liquid volume containing the amount entered.
U-100 syringe mark
liquid volume in mL × 100The 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.
FDA-approved prescription products may exist for specific indications, formulations, strengths, and routes. That does not establish the status or suitability of any differently labeled, compounded, or research product.
