I just started this week takin sust 250. I've taken my second shot, followin precautions I've read on threads (cleanin injection site, replacing pins after drawin from the vial, never resused a needle,cleanin site afterwards ec...) but my ass though is a little red and has a lump, and is a bit sore nothin extreme. Could it be infected and if so what could be the cause? And ya I am paranoid lol
