EXAMPLE RECORDConcentration calculation
- Stated amount
- 12 mg
- Final volume
- 4 mL
- Concentration
- 3 mg/mL
12 mg ÷ 4 mL = 3 mg/mL

A LITTLE CONTEXT GOES A LONG WAY.

mg ≠ mg/mL
LABEL BASICS
An amount isn't a concentration.
What the number on a vial tells you, and what it doesn't.

STORAGE & LIMITS
How long does BAC water last?
Understand expiry, opened-vial dating and refrigeration instructions.
Read the guideBefore you use a calculator
A vial amount is not a concentration.
A label that states 10 mg describes an amount. In a final volume of 2 mL, the concentration would be 5 mg/mL. That example does not tell you to add 2 mL to a particular product.
BAC water is a pharmaceutical diluent containing a preservative. Formulation and intended use depend on the exact label. Preservative does not prove a prepared mixture is sterile or stable.
Ingredients and intended purpose · Product labeling reference
Three checks before calculating
- Copy each number with its unit. mg and mcg describe mass; mL describes volume.
- Use the final volume from your instructions. Vial strength alone does not determine a suitable dilution.
- Check the actual device scale. U-100 means 100 units per mL, not a universal conversion for every syringe.
LOOK UP. DON'T GUESS.

How this peptide reconstitution calculator works
Enter the amount in your vial and the final liquid volume from your instructions. The calculator divides the amount by the volume to show how much is in each mL.
Need a measurement? Enter an amount in mg or mcg. You will see its volume in mL and the matching U-100 scale reading. The tool checks your numbers; it does not choose a dose or a mixing method.
