Overview
Reconstitution is the process of mixing bacteriostatic water with lyophilized (freeze-dried) peptides to create a ready-to-use injectable solution. While it may seem complex at first, this guide will walk you through each step with confidence and safety in mind.

What You’ll Need
Lyophilized peptide vial (e.g., BPC-157)
Bacteriostatic water (bac-water)
3 mL sterile syringe (for bac-water)
1 mL insulin syringe tip (used as vent)
Alcohol prep wipes
Gloves (optional, recommended)
Clean, sanitized workspace
Sharps disposal container
Step-by-Step Instructions:
Step 1: Sanitize and Prepare
Wash your hands thoroughly.
Wear gloves if available.
Disinfect your work area with alcohol.
Prepare all tools and supplies.
Step 2: Prepare the Bacteriostatic Water
Remove plastic cap from bac-water vial and disinfect rubber stopper.
Draw equal air into your 3 mL syringe (for pressure balance).
Inject air into bac-water vial, flip it, and draw out 2.5–3.0 mL of water slowly.
Avoid air bubbles—tap syringe if needed.
Step 3: Prepare the Peptide Vial
Remove plastic cap and disinfect the peptide vial’s rubber stopper.
Insert an empty insulin syringe tip at an angle to act as a vent (lets air escape).
Step 4: Add the Bac-Water to Peptide Vial
Insert the water-filled syringe into the center of the stopper.
Gently inject bac-water down the inside wall of the vial (not directly onto powder).
Remove both syringes and dispose of safely.
Step 5: Allow to Dissolve
Do NOT shake.
Gently roll or tilt the vial side to side.
Let sit for 10 minutes until the powder is fully dissolved into a clear solution.
Step 6: Safe Disposal
Recap syringes using a flat surface (never with your hands).
Dispose in a sharps container—never in regular trash.
Best Practices and Safety Tips
Storage:
• Reconstituted peptides: refrigerate and use within 30–45 days
• Lyophilized peptides: store in freezer at -20°C (-4°F) for 2+ yearsClean Technique:
• Always use new sterile syringes and alcohol wipes
• Avoid puncturing vials multiple times
• Do not reuse syringes or needlesHandling:
• Inject water slowly to prevent foaming
• Avoid shaking to preserve peptide integrity
• Ensure clarity of solution before use
Final Notes
Reconstituting peptides like BPC-157 or TB-500 is simple with clean technique and a calm approach. Always consult a healthcare provider or compounding pharmacist if you're unsure.
