How to Reconstitute Peptides
Gather sterile gloves, safety goggles, a clean workspace, a sterile syringe, bacteriostatic water and your peptide vial. Ensure everything is sterile before beginning.
Allow both the lyophilised peptide powder and the bacteriostatic water to reach room temperature before reconstitution to ensure an even mix.
Remove the metal cap centre from both vials. Wipe the rubber stoppers thoroughly with an alcohol swab and allow to air dry completely.
Using a sterile syringe, draw up your measured bacteriostatic water. Insert the needle into the peptide vial at a 45° angle and slowly inject the water down the side of the vial. Do not shake — gently swirl until dissolved.
Reconstituted peptides should be stored at +4°C (refrigerator) for up to 3 weeks, or at -20°C (freezer) for 3–4 months. Avoid repeated freeze-thaw cycles.
