Handling and reconstitution
Sealed lyophilized vials are stable in ambient transit and should be held cool, dry and dark on arrival; −20 °C is preferred for long-term storage. A typical working preparation for this vial size is 10 mg + 2 mL = 5 mg/mL. Direct the diluent stream down the inside wall of the vial rather than onto the cake, swirl gently rather than shaking, label the vial with concentration and date, and hold reconstituted material at 2–8 °C. Use the peptide calculator to convert milligrams to U-100 units.
