How to reconstitute
1
Gather: peptide vial, bacteriostatic water, sterile syringe(s), alcohol swab.
2
Draw 3.0 mL of BAC water into the syringe.
3
Wipe the rubber stopper of the peptide vial with an alcohol swab; let it dry.
4
Inject the BAC water slowly down the inside wall of the vial; avoid shooting directly at the powder or foaming.
5
Gently swirl or roll the vial until the powder is fully dissolved; do not shake.
6
Your reconstituted vial is ready. Store refrigerated at 2–8°C. Use within 4–6 weeks; avoid freeze-thaw cycles.
