Reconstitution calculator
Enter the amount in the vial and the bacteriostatic water volume to calculate concentration. Add a reference amount only if you also want draw volume and syringe units.
Inputs
Amount in vial
Use the labelled peptide amount before water is added.
Bacteriostatic water added
Enter the final water volume added to the vial.
Reference amount (optional)
Leave blank if you only need concentration.
Results
Enter the vial amount and water volume to see concentration. Add a reference amount if you also want draw volume.
How it works
Concentration is the labelled peptide amount divided by the water volume. For example, 10 mg in 2 ml gives 5 mg/ml, or 5000 mcg/ml. The draw volume for a dose is the dose divided by that concentration, and insulin-syringe units assume a standard U-100 syringe where 1 ml is 100 units.
Doses per vial is the whole number of full doses the vial contains, rounded down.

This calculator is for educational and informational use. It checks arithmetic only, does not recommend a dose or protocol, and does not replace qualified clinical guidance. Verify vial labels, units, and calculations independently.
Track this in the app
In the app, Peptideo can store vial concentration and supply details privately so the same arithmetic is available when logging doses.
