Okay you may be aware Aaron is going through trial pump process. We have changed two sites with Inset 30. Well Aaron is thin not much meat on him. I mean he is not boney he just does not have alot of pinch an inch as some would say. So thus far we have used each butt cheek for site. Where do you position sites at? Can we do back of arm, inner thigh etc.? I'm not ready to do his tummy but if i had to i could. Thanks!!
