i nkow people have posted about swelling up, and being in pain but i had another question. this is my second cycle, and my first cycle it didnt really happen.ya i was sore for a day or so, but now its really swollen and VERY VERY painful. my source recently switched oils. im not sure what he was using before, but now hes using cotten seed oil. i have injected myself with cotten seed oil about 3-4 times, and every time i swell up and in alot of pain...think this could be a reaction to the different oil? has this happened to anyone else? by the way, its Test E im injecting...325mg/ml
