If being sterile is of utmost concern; I dont know why this sticky will say draw 1cc of air (from the atmospere with every fxxx thing in it...germs, bacteria, viruses, etc) into the plunger...and then push it into the vial.....just to build pressure and help you draw easily.......
Remember, you do the same thing (draw abt 1cc of air on top of the amount of oil/whatever uv already drawn) before you can change needles?........double trouble.....even tho u push this air out b4 u inject into ur body......but the oil in the pluger is already contaminated.......right?
