Yeah, I wouldn’t worry about it. When doing an IM injection correctly your biggest concern would be going through a vein, which in itself is still not a big deal. I’ve hit a vein before, you feel a pinch, you go “oh, that sucks” and keep pushing past it. What’s done is done, you can’t unstick the vein. And, if by chance you do inject into a vein, so what… You’ll cough a little bit (unless it’s Tren, then you’ll practically die from coughing), it’ll leave a bruise, and you’ll have a little blood dribble out.
I don’t even aspirate anymore, no need, because it doesn’t change anything. I’m not going to pull the needle out, replace it with a new clean one and retry. As a matter of fact they don’t even teach you to aspirate in nursing school anymore, IM or SubQ.
