How to Reconstitute a Vial

01

Check the total peptide amount printed on the vial label and select the matching amount in the calculator.

02

Add your chosen volume of bacteriostatic water. More water produces a more dilute solution and more units per mg; less water produces a higher concentration and fewer units. A standard vial typically holds no more than 3 mL.

03

Gently swirl the vial or roll it between your palms until the powder fully dissolves. Do not shake.

04

Use the calculator above to find how many units to draw on a U-100 insulin syringe for the target research dose.

05

Store the reconstituted vial refrigerated at 2–8°C between research draws. Do not freeze. Protect from light.

06

Some reconstituted compounds may temporarily appear hazy or more viscous after refrigeration. If this persists after gentle rolling, contact Peptique.
