The last two times I injected I have had a lot of gear run back out the injection site. I have had this happen before a little but not this much. I am using 1 cc fina and about 1.3 cc prop because it is only about 90mg/ml. I am using 1 " 23g pins in delts and 1 1/2 23g in a$$. It has happened in both spots, what the hell is going on?
