Ok I've noticed when i've been injecting that a minute amount of oil seeps back out of the injection site. Not a lot maybe like .05ml but I'm a "waste not, want not" kinda guy. I inject slowly and even leave the needle in for another 10 seconds after the injection but still get the same effect. I use a 1inch 22g needle (mainly cause i hate using one pin to draw and one to inject) Any way to prevent this or is it just something you just have to deal with?
