I find it very hard to eliminate all the bubbles of of my sust.... I can squeeze a bit of the air out, even after taping the sryinge and lettng is set a while. There is always, a few bubbles that the only way to get them out is to empty a shit load of sust out, I don't want to do that. I know intremuscular injections aren't the the most to be concerened about with the air bubles, but I just can't seem to get em all out.....
