Running my third cycle of just test e. Did my 4th injection the other day and now have a red area about 2 -3 inches below the injection site (shoulder injection). Same Home brew test e that I used on my last cycle with no problems. No issues with the first 3 injections. When I put the needle in the shoulder at first I felt like I hit a nerve so I pulled it out and inserted about 1/2 inch away. Could that cause this?
