Didn't see the knot part, no that isn't normal.But a knot the size of my arm under my delt? I've been injecting for about 15 years now and never had anything to this extent happen. I know there were issues with the test e raws, but I've obviously haven't seen any else in here complaining about this either. So don't get me wrong, not blaming the source. Just trying to figure out what the hell is going on because this was not normal. Even my doctor said it wasn't.
