Like the title says I recently combined a sustanon blend with tren a for a total of 2ml. Injected in the upper quad as I always do (clean as possible). I have developed a large inflamed area near the pin site. The muscle is knotted badly. I can walk bend and do all that but there is some pain. Im more worried about possible abscess or infection. I have injected the same gear multiple times with no pain or inflammation. What are your thoughts or experience with this? Thanks guys
