My last cycle, one year ago, was finished with prop and winny. The pain on the injection site was unbearable not to mention the flue-like symptoms. After researching I came accross a thread that recommended mixing it with B-12. Well, I did so but the pain was not reduced(it was legit, sterile human B-12). Something strange came up. A week later when shooting again in that spot, while aspirating, a strange light redish, oily, almost puss-like substance filled the syringe. I had no pain, no fever or symptoms of any kind. I got this result several times, I had to stop the prop. However I never had a problem after that with infections, etc. Has anybody had this happen to them?
