How to reconstitute

Wash your hands thoroughly and clean your work surface. Work in a clean, draught-free space.

Wipe the rubber stoppers of both the peptide vial and the bacteriostatic water with an alcohol swab, and let them air-dry.

Pull air into the syringe equal to the water you'll draw, inject it into the water vial, then invert and slowly draw your measured volume (e.g. 2 mL for a 20 mg vial).

Insert the needle into the peptide vial and run the water slowly down the inside glass wall — never directly onto the powder. This prevents foaming and protects the peptide.

Do NOT shake. Gently swirl or roll the vial; most peptides dissolve within a few minutes. Avoid heat and direct sunlight.

Keep the reconstituted vial refrigerated (2–8 °C) and protected from light. Discard if the solution is cloudy, discoloured or contains particles.

Calculate concentration

Concentration = total peptide (mg) ÷ total water (mL).

So 1 mL = 10 mg, and 0.1 mL = 1 mg.

Important notes

• ✓ Use sterile technique throughout.
• ✓ Always reconstitute with bacteriostatic or sterile water — never tap water.
• ✓ Store reconstituted vials refrigerated and respect each peptide's stability window.
• ✓ Discard if cloudy, discoloured or containing particles.
• ✓ A Certificate of Analysis is available on request.
