Reconstitution Guide

4 Steps

Wash hands thoroughly and put on sterile gloves and goggles. Ensure your workspace is impeccably clean and that you have all necessary tools ready:

  • Lyophilised peptide in a glass vial
  • Sterile syringe
  • Bacteriostatic water
  • Gloves and safety glasses

Cleanliness and sterility of the environment is critical.

Bring both the peptide powder and bacteriostatic water to room temperature before beginning — using cold solutions can interfere with reconstitution. Carefully remove the central part of the metal cap from the vial and disinfect the rubber stopper with an alcohol swab. Repeat the same cleaning process for the bacteriostatic water vial.

Using a sterile syringe, draw up the required amount of bacteriostatic water. Tilt the peptide vial at a 45° angle and slowly inject the water down the interior wall of the vial — do not spray it directly onto the powder. This minimises bubble formation and ensures smooth, even dissolution. Once all the solvent is added, gently swirl the vial — do not shake or vortex.

Store lyophilised (dry) peptide at −20°C for long-term storage or 2–8°C for short-term use. Once reconstituted, store in the refrigerator at 2–8°C. Reconstituted peptide solutions are generally stable for 3 or more weeks refrigerated and 3–4 months at −20°C. Avoid repeated freeze-thaw cycles as these can compromise peptide integrity.
