First get a syringe, preferably an insulin syringe as you do not want to use a large gauge needle, and insert it into the powdered chamber and pull out the plunger to let some of the pressure out. This will make it easier to push the water into the chamber.
Second, use the butt end of a pencil, pen or use a screwdriver to push the plunger all the way in until all the water has been forced into the powder chamber
Lastly, slowly swirl around until all the powder is dissolved
Ready to inject
