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.
Draw the syringe up to
That's one 250 mcg dose. Add 2 mL of water to your 10 mg vial first.
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. For the full calculator with presets for every peptide on the site and a protocol planner, see the peptide calculator.
