📖How to Reconstitute Peptides

A simple step-by-step guide to safely prepare your peptide vials.

🧰

What You Need

  • Lyophilized (dry) peptide vial
  • Bacteriostatic water (BAC water)
  • Syringe (e.g. 1ml insulin syringe with needle)
  • Alcohol swabs
1

Step 1: Clean the Vial

  • Wipe the rubber stopper of the peptide vial with an alcohol swab and let it dry.
  • Wipe the top of the BAC water vial with an alcohol swab.

Step 2: Draw Bacteriostatic Water

  • Pull the syringe plunger to draw air equal to the amount of BAC water you want to add.
  • Insert the needle into the BAC water vial and inject the air (to avoid vacuum).
  • Invert the vial and draw the correct amount of BAC water into the syringe.
  • Remove the needle and tap the syringe to move bubbles to the top; gently push the plunger to expel air.

Step 3: Add Water to the Peptide Vial

  • Insert the needle into the peptide vial through the rubber stopper, aiming the stream of water at the side of the vial rather than directly onto the powder to reduce foaming.
  • Slowly depress the plunger to add the BAC water.
  • Remove the syringe. Do not shake the vial; you can roll it gently to help the powder dissolve.

Step 4: Storage

  • Reconstituted peptides are typically stored in the refrigerator (2–8°C).
  • Check the product information for how long the reconstituted solution remains stable (often 2–4 weeks when refrigerated).
