No matter what I do I can't seem to get all the air bubbles out of the syringe when i fill it with test e, and its not those little tiny bubbles that look like dots. There's always at least one significant air bubble left no matter how much i tap it and try to push it out. I'm drawing from a little glass amp and theres no rubber on the top so i can't turn it upside down like i'm use to. Could an air bubble harm me or should i just do the best I can and inject it....thanx
