With the 18 G needle still inside the vial, gently turn the vial upside down and make sure that the liquid is completely covering the tip of the needle. Slowly pull the plunger back until the proper dosage of testosterone is in the syringe. Make certain to check for air bubbles at this time. If any are present in the syringe, tap it lightly with your fingers until the bubbles rise to the top of the syringe. Slowly push the plunger up to gently force any bubbles out of the syringe before removing the needle from the vial. If necessary, pull the plunger slowly back to complete filling the proper dosage of medication.
