    What you need

    • The peptide vial (freeze-dried powder)
    • Bacteriostatic water: sterile water with 0.9% benzyl alcohol, which keeps a multi-dose vial from growing bacteria
    • A new sterile syringe and needle for mixing, sized for the volume you're adding
    • Two or more 70% isopropyl alcohol swabs
    • A sharps container for the used needle

    Good practice

    • Use a fresh needle every time and never recap a used one. Drop it straight into the sharps container.
    • Once a stopper is swabbed, don't touch it. If you do, swab it again.
    • Keep the needle tip under the waterline while drawing, or you'll pull in air.
    • If the finished solution stays cloudy or has particles after it settles, don't use it.
    • Bacteriostatic water is not for newborns. Ask your pharmacist if you're unsure which diluent you need.
