This is my 2nd week of 500mgs a week of sustanon, along with 800mg of deca a week. I do the sustanon shot by its shelf. For the 2nd week in a row, by day 3 after the shot I feel like a car hit me (flu feelings) and It lasts for about 2 days (aches ,pains, sever night sweats), also it doesnt matter if I throw it in the leg or arm it irritates the crap out of my joints. Do you think this is normal or is my stuff crap. Deca runs fine and I feel like a tank on it.
