until today I was on testosterone cypionate suspended in cottonseed oil. The first injection I had went well no side effects at all. But after that one they got increasingly more painful swollen and itchy after each shot. After maybe my third shot I noticed crystals forming in it. I did some research that suggested that in the cold (I live in a badly heated apartment in Chicago) this can happen, just heat it up a bit, shake it around and once it looks normal you're good to go. So I was doing this but my reactions were getting so bad I finally went to the Dr. He switched me to Testosterone Enanthate suspended in sesame seed oil. My first shot on that will be tuesday so hopefully I wont have any strange reactions this time around. But I looked at my old vial today and it was very cloudy. So now I'm thinking perhaps it wasn't allergies, maybe I got a bad batch of T first time round? Has this ever happened to anyone else?
