Hi guys. I done my first injection of Sustanon on Friday last week to start my cycle off, only to see a big red mark was left next to the injection site on my delt the next day. Ive never had this from previous cycles. Its only just started to fade, i done my second Injection yesterday in my glute, and the same thing has happened in my glute its left a massive red mark at the injection site? The Sustanon is from Intex Pharma, could it be the lab? Appreciate any feedback, cheers.
