I was doing an injection of 75mg of Tren in my delt today. The needle went in pretty much painless and i aspirated didnt see anything unusual. But when I pulled needle out blood started spraying straight up in the air and then ran all down my arm. I have been doing ed injections for a month now and have done 2 cycles of ed injections before this and nothing like this has ever happened. Did I inject straight into a vein? If so is that a waste of the Tren?
