I'm taking 500mg Sust/week, shot eod...400mg deca/week...I'm just starting my 3rd week and took 1/2cc of sust on Friday. I woke up Saturday and couldn't hardly move at all, Sunday was even worse. I mean I felt like every muscle in my body was cramped. I hadn't worked out since Sunday. Went to the doctor today and he gave me some Vicodin which has made it all better but what the hell?? Anyone ever heard of anything like this, I've used both numerous times in the past with no problems???
