Peptide reconstitution calculator

Calculate the concentration, the volume per dose and the exact units in your insulin syringe. Pick a preset or enter your values and see it instantly.

Vial data

Pick a peptide or enter your values.

Peptide (preset)Auto-fills the vial size. You can also enter it yourself.

Peptide in the vial

Total amount of peptide in the vial (on the label).

Bacteriostatic water to add

The liquid you reconstitute the powder with. More water = more diluted dose.

Target dose per application

mcg

1000 mcg = 1 mg. So 2500 means you want 2.5 mg per dose.

Insulin syringe (U-100)The size of your insulin syringe. Sets how far you can draw.

Educational tool for reconstitution calculations in a research context. Always verify your calculations. It is not usage instructions or a medical recommendation.

How to use the calculator

Peptide in the vial (mg): the total amount of peptide, per the label.
Bacteriostatic water (mL): the liquid you reconstitute the powder with. More water = more diluted dose.
Target dose (mcg): how much peptide you want per dose (1000 mcg = 1 mg).
Syringe: the size of your U-100 insulin syringe.

The calculator returns the concentration (mg/mL), the mcg per syringe unit, the volume per dose and how many doses the vial yields. It is an educational tool for a research context; always verify your calculations.

FAQ

About reconstitution

It calculates the vial concentration, the volume per dose and how many units to draw into an insulin syringe, from the peptide mg, the bacteriostatic water added and the target dose.

Each mark on a U-100 insulin syringe equals 0.01 mL. The calculator tells you how many mcg each unit holds at your concentration.

1000 micrograms (mcg) equal 1 milligram (mg).
