On my fourth injection of my winstrol cycle, felt some discomfort during and a little after the injection.(in glute felt almost like a burn) The following morning,(today) I woke up with a bump and a little soreness but nothing I haven't already experienced. About twelve hours later, I noticed some redness in the area of the bump. Does anyone have any input on the possible causeie. infection or just bad injection. Also, With the possibility of an early caught infection, how long a dose of antibiotics should I take?
