I took a Test E shot last night. It was the first time i did it in my shoulder. I used a 23g i beleieve 1 inch long. The shot went fine no pain what so ever but now it is killing me. it is not hot to the touch but there is a slight knott and it hurst to even tuch it a little bit.. I did 1cc 300mg.. I cnt imagine doing this for 20 weeks
