I used QV prop at the beginning of my cycle, with no problems other than a little pain. Now at the end of my cycle, back on with a new vial of QV prop and I have had a quite different experience. Injected my left shoulder 2 days ago (definitely in muscle) and within 6 hours at the delt insertion on lateral aspect of my arm began hurting (not so much the injection site.) increased through the night. Next day my skin in that area is reddened, and can feel hardness under the skin. again this isnt the injection site but a little distal. I have since injected my glute and noticed the same redness and hardened area under the skin (this time around the injection site). Not to mention pain. This all with-in one or 2 days of the injection. Anyone else have this problem?? I am concerned, either it is Dirty gear or High BA content and I am reacting to it. Checked out the lot number on QV's website and it checked out. Plus its from the same source as my first vial so not worried about its authenticity. I dont want to miss an injection, but I also dont want to end up with an abscess. I am going to send a sample out for gram stain and culture but the results will be days....thanks in advance.
