P21 dosing guide

Reconstitution steps

Every step below uses the numbers you entered above.

1. 1
   Wipe both stoppers

   Swab the rubber tops of the 10 mg P21 vial and the bacteriostatic water vial with fresh alcohol pads. Let them air dry for a few seconds.

2. 2
   Draw 2 mL of BAC water

   Pull 2 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 20 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 20, that's your 1.00 mg 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.
