Oil is thicker than blood- obviously. So as long as you inject deep enough, and slow enough... the oil will stay in when blood comes out- right? I see a lot of people worried about losing gear from bleeding (myself included), but I do not see how it can be forced out of the muscle.
I understand that if you inject too fast, the gear can start protruding and maybe even be ejected. So I think that as long as you go slow and deep you will be g2g- no matter how much blood escapes
