Started cycle last week. took 250mg of test in outer upper quad, hit a small vessel when asp. so pulled out and re positioned. no pain went well. I am very causious about sterility but 4 days later had to see doctor for fever swelling and redness that coverd most of thigh. Other shot sites wher fine. Gave my test shot in ass yesterday, asp. syrnge and once again blood. Moved pin over and was fine. I now have a lump that looks like a second ass cheek and very sore. Using a 23g 1". Last cycle never had this happen before. Sure had a few sore spots but nothing like this. Last cycle pin guage was a 22 at 1.5". No redness or heat on ass yet. Doc said blood vessle last time bleed into quad muscle and thats what got infected. Am I doing something wrong? Im starting to get a little "pin" Shy for fear of infections.
