Complete Peptide Reconstitution Guide | Best Peptide Protocols

Introduction

Proper reconstitution is essential for maintaining peptide stability and effectiveness. This guide covers everything you need to know about reconstituting lyophilized peptides.

What You'll Need

Bacteriostatic water (BAC water)

Insulin syringes (29-31 gauge)

Alcohol swabs

Your lyophilized peptide vial

Step-by-Step Process

1. Prepare Your Workspace

Clean your workspace thoroughly and wash your hands. Gather all materials before beginning.

Step 1 — Clean, organised workspace with all supplies laid out

2. Clean the Vial Tops

Use alcohol swabs to clean the rubber stopper of both the peptide vial and the bacteriostatic water vial.

Step 2 — Wipe both rubber stoppers with an alcohol swab

3. Draw the Bacteriostatic Water

Using an insulin syringe, draw your desired amount of bacteriostatic water. The amount depends on your desired concentration.

Step 3 — Draw bacteriostatic water into the syringe

4. Add Water to Peptide Vial

Insert the needle into the peptide vial at an angle, aiming the stream at the glass wall, not directly at the powder. This prevents damage to the peptide.

Step 4 — Angle the needle so water runs down the glass wall, not onto the powder

5. Allow to Dissolve

Do not shake. Let the peptide dissolve naturally, which may take 5-10 minutes. You can gently swirl if needed.

Step 5 — Let it dissolve undisturbed; gently swirl if needed, never shake

Storage After Reconstitution

Store reconstituted peptides in the refrigerator (2-8°C). Most peptides remain stable for 4-6 weeks when properly stored.

Common Mistakes to Avoid

Never shake the vial vigorously

Don't inject water directly onto the powder

Always use bacteriostatic water, not sterile water for long-term storage

Keep away from light and heat
