wussup Scorpion, I also noticed the back pain, but it was after working out my legs on Friday and doing some lunges.. It was'nt unbearable but it was a little uncomfortable.. I have been rubbing some icy-hot and that seems to make it feel better. I heard that SD does have that side effect though.. If its really bad just take some asprin.. I dont know what else to tell you bro.

When are you guys taking the SD?? i'm taking 10mg @ 11am and then my second 10mg @ 5pm since it has a 6hr half life..
