new to the boards and have a question regarding sustanon use in my cycle...im 42 190lbs and been on and off cycles for sever years. i usually cycle with cip, deca and sometimes tren. i recently tried a cycle of sustanon and developed huge cyst in my butt and it got to point i had to go to emergency room and have cut open and drained. Having pinned for years and being completely sanitary i thought there was something wrong with the product or i had an infection. it was insanely painful. the distributor answered my questions and said not an infection but an allergic reaction to oil they used. they even reshipped a whole new order for free and with additional compensation. i have several questions. I had no problem with any other products from this company before...could it be allergy? is it common for sust to do this. I am pinning 2 cc's at a time, is that to much? and is there anything i can do to prevent the cysts from the shots or alleviate the pain? any insight will be helpful. thank you
