How to Reconstitute Peptides with Bacteriostatic Water: Step-by-Step Guide
Author : Aurora Damian | Published On : 14 Oct 2025
Reconstituting peptides with bacteriostatic water (BAC water) is an essential step to ensure accurate dosing and preserve the peptide’s stability. The process might seem tricky at first, but with a few simple steps, you can mix your peptides safely and effectively.
Step 1: Gather What You Need
Before you start, make sure you have:
-
Peptide vial (lyophilized powder)
-
Bacteriostatic water
-
Alcohol swabs
-
Sterile syringe and needle
Step 2: Clean the Vials
Use alcohol swabs to clean the rubber stoppers of both the peptide vial and BAC water vial. This prevents contamination during the process.
Step 3: Draw the BAC Water
Using a sterile syringe, draw the desired amount of BAC water. The volume depends on your dosage preference—commonly between 1–2 ml per vial.
Step 4: Inject the BAC Water Slowly
Insert the needle into the peptide vial and let the BAC water slowly run down the inside wall of the vial. Avoid injecting it directly into the powder, as this can damage the peptide.
Step 5: Gently Mix
Do not shake the vial. Instead, swirl it gently until the powder is completely dissolved. The liquid should turn clear with no visible particles.
Step 6: Store Properly
Store the reconstituted peptide in the refrigerator (between 2°C–8°C). This helps maintain its effectiveness for up to several weeks, depending on the peptide.
Conclusion
Reconstituting peptides with BAC water correctly is crucial for maintaining purity, safety, and potency. Always handle materials in a clean environment and follow recommended storage guidelines.
