Add Bacteriostatic WaterBacteriostatic water is the standard diluent for peptides. It contains 0.9% benzyl alcohol which prevents bacterial growth.

How much water you add determines the concentration of your solution.

How to Reconstitute a Peptide — Step by Step

  1. Gather your supplies
    You'll need: your peptide vial, bacteriostatic water, a 1ml insulin syringe, and alcohol swabs.
  2. Draw the bacteriostatic water
    Using a fresh syringe, draw 2ml of bacteriostatic water.
  3. Inject slowly into the peptide vial
    Aim the needle at the glass wall — not directly at the powder. Let the water run down the side gently. Never shake the vial.
  4. Swirl gently until dissolved
    Roll the vial between your palms. The powder should dissolve into a clear solution within a minute.
  5. Draw your dose
