anyone ever use it and experience abnormal pain swelling and rock hard muscle in the injection area. i did a cycle of it last summer and every time i pinned it within a day or two the area always got lumped up rock hard then went away in about a weeks time. now this summer went to finish the 2 vials i have left of it same reaction and test flu after every pin. just sucks dont know why it happens. just curious if anyone else has ever had this happen with pro chem gear or any other gear they have used
