Peptide Reconstitution Calculator

Calculate how much bacteriostatic water to add to your peptide vial, the resulting concentration, how much to draw in your syringe, and how many doses you'll get per vial.

Results

Enter vial size, BAC water amount, and desired dose to see results.

How to Use This Calculator

  1. Select your peptide (optional) - this will show the average purity from lab tests on Peptigrity.
  2. Enter vial size - the amount of peptide in your vial in milligrams (mg). Common sizes: 5mg, 10mg.
  3. Enter BAC water volume - how many millilitres of bacteriostatic water you want to add.
  4. Enter desired dose - how many micrograms (mcg) you want per administration.
  5. Choose syringe type - this determines how many units to draw on your syringe markings.

What Is Peptide Reconstitution?

Peptide reconstitution is the process of dissolving a lyophilized (freeze-dried) peptide powder with a sterile solvent - typically bacteriostatic water (BAC water). This creates an injectable solution at a known concentration, allowing you to measure precise doses using an insulin syringe.

BAC water contains 0.9% benzyl alcohol as a preservative, which allows the reconstituted solution to remain stable for approximately 28 days when stored at 2-8°C (refrigerated). Sterile water without preservative should be used within 24-48 hours.
