Mixing it, step by step

Step by step

Reconstitution steps

Every step below uses the numbers you entered above.

  1. 1
    Wipe both stoppers

    Swab the rubber tops of the 5 mg HCG vial and the bacteriostatic water vial with fresh alcohol pads. Let them air dry for a few seconds.

  2. 2
    Draw 5 mL of BAC water

    Pull 5 mL of bacteriostatic water into a reconstitution syringe (usually a 3 mL syringe with a 21g needle).

  3. 3
    Add water slowly, down the side

    Inject the water against the inside wall of the vial, don't blast it directly onto the powder. This protects the peptide from shear damage.

  4. 4
    Swirl, don't shake

    Gently swirl until the powder is fully dissolved and the liquid is clear. Never shake, foaming denatures the peptide.

  5. 5
    Draw 10 units on a 1 mL syringe

    On your 100-unit (1 mL) insulin syringe, pull the plunger back until the rubber tip lines up with 10, that's your 500 mcg dose. Tap out any air bubbles, then inject as directed.

  6. 6
    Store refrigerated

    Cap the vial and store at 2–8 °C (36–46 °F). Most reconstituted peptides remain stable for 3–4 weeks refrigerated.
