Reconstitution Calculator
Work out your concentration.
Enter how much peptide is in the vial and how much bacteriostatic water you're adding. You'll get the concentration, plus how much to draw for a target amount on a standard U-100 insulin syringe. Concentration math only — see the note below.
How to reconstitute
General handling steps.
Standard laboratory handling for lyophilized (freeze-dried) research peptides. Always follow your own approved research protocol and any compound-specific storage note.
- Let both the lyophilized vial and the bacteriostatic water reach room temperature, and wipe both stoppers with an alcohol swab.
- Draw your measured volume of bacteriostatic water. Add it slowly down the inside wall of the vial — aim the stream at the glass, not directly onto the powder.
- Let it dissolve on its own, or swirl gently. Do not shake — peptides are fragile and foaming can degrade them.
- Once fully clear, store refrigerated (typically 2–8 °C) and keep it out of light. Follow the compound-specific storage note for your product.
- Use the calculator above to convert your target amount into a volume / number of units to draw.
