Hey guys.......I have a question about Sustanon-250 injections. I just injected (for the first time ever cycling) 1 cc into both of my vastus lateralis (the muscle on the outside of the legs). The immediate day after I did so, I experienced extreme soreness in both of my legs. It was so bad as to the point I had trouble walking (like the soreness after doing squats after taking a while off and not stretching). Is this to be expected and will the soreness/pain decrease over the next couple shots, or did I do something wrong w/ the injection? I followed the proper injection procedure to the T, or at least I thought I did. Please let me know.
