Every time I’ve tried injecting into my quads (mid-outer quad) I could barely walk for a week and/or I got an infection and had to get in antibiotics. I injected the top of my outer vastus lateralis and went straight down. I’ve tried 1cc and 1/2cc injections of test-c with both 25 gauge 1 inch needles and 29 gauge slin pins. I carry very little fat in my quads and they are very vascular. I wonder if that’s the cause? Any suggestions from those who have experienced the same problem would be greatly appreciated. The last time I tried a quad injection was about 5 years ago. I’m afraid to try it again because the last time I tried a quad injection I got cellulitis. It was Pharma grade test and the injection site was clean.
