Taking 1cc test twice a week. On my 4th week I decided to do shoulders. Everything was fine until I worked out the next day. Now my shoulder is red, painful, and swollen. Any suggestions I would preciate it.

always shoot in assballs. Min veins and nerves. Ive done hundreds and never ever had problemes in that area. Even if i never cleaned the place and sometimes reused needles.
