Right now I am taking in 1.5ccs of gear everyday. I use a 23 gauge 1.5 inch pin to shoot. I shoot in my right delt, left delt, right quad, left quad, right glute then left glute. So its a 6 day rotation before that same area is injected in again? Is that adequate time to allow the oil to leave not cause insane scar tissue build up? Next time I order pins I think I will order 25 gauge, 1 inch needles.
