For the first 2.5 weeks I've injected 2cc's of tren eod and 250mg's of sust every six days, and the injects weren't the least bit painful. This last week though has been a different story. My inject sites sore as a mofo for like two days after! Has anyone else had this problem? I rotate six different inject spots and nothing is ever red or bruised after any of them, just all of a sudden sore, sore, sore!!![]()
