Hi, This is my my third cylce. I just started it yest. Did 250mg Cyp. In my shoulder where i feel most comfotable injecting. no pain the whole day but woke up this morning and felt like i had surgery. Never and Never had experienced pain and soreness and a lump like this before not from enan. or sust. ?? keep in mind the bottle does say prop but my source just said he used an old bottle to fill my forty C's. It was either those bottles or a 100c bottle which is too hard for me to keep hidden?/ So i have never ran prop and heard about the pain and wondering if it actually is prop?
