Step-by-step protocol for safe reconstitution
Allow the peptide vial to reach room temperature before opening.
Using a sterile syringe, draw the calculated amount of bacteriostatic water.
Inject the water slowly down the side of the vial — do not inject directly onto the powder.
Gently swirl the vial until the powder is fully dissolved. Do not shake vigorously.
Store reconstituted peptide at 2-8°C and use within 4-6 weeks.
Always use sterile technique and new syringes for each use.
