mixing b12 with oil based juice???

It is difficult to tell if there is any air in the syringe even when you shake the syringe and partially emulsify the solution. What is everyones take on this

i always put a little bit of air in the pin so i can make sure i get all the juice out of the syringe. If you put half a cc of air in the top and shake it, most of the air will go to that upper space. If your gonna try that make sure you have really really good technique, you dont want to inject that half cc of air in your body!!
