So I've been ecstatic with my progress the past 6 months. Did my shot on Fri as usual, woke up Sat w some pain and swelling in quad (switched for a few months, no pain usually). Thought I pulled something bc I just worked legs Thurs. Could barely move it this am. Went to Dr and crap, I've got an infection! They pumped me full of antibiotics, and have to take for the next 10 days. She said that something must've contaminated my bottle and to trash it and start a new one.
I follow same procedure every time. So not sure what happened. Moral of the story I guess is stay sterile, and if your body has a reaction, act quickly!
