I had the same problem with test prop. I mixed it with fina and shot it and my leg lumped up and got real tender and red all around the injection site. I figured that I hit a vein or something, and shot the other leg. Now that leg swole up. I then thought that it might be the fina, so I seperated the shots and shot myself in each ass cheack. Suprise, Suprise, the cheack with the test prop swole up. It took a week for the swelling to go down. I tried two different bottles of test prop thinking one was bad. That didn't work. I have come to the conclusion that I'm allergic to it or something. I just quit taking the test prop. There's my expirience with it. You might have the same thing, who knows. At least I'm looking forward to my shots again.
