Bro the back pumps are vicious on dbol!! I stopped dbol because of that. Deadlifts were impossible! But I was running 50mg. Some people say to take Taurine for back pumps. I never have used Taurine before, so I cannot comment.
By the way, I do recognize you from another board now
I cannot wait to see your results bro. Get those pics up!!
But hey... those 'knots' are definately back pumps. They suck ass... but at least you know that the dbol is doing its thing. About the night-time cravings.... I don't know what you should do. I was always waking up around 2am and grabbing a giant bowl of frosted mini wheats. After 3-4 weeks I was putting on too much fat. Maybe you should just down a shake with some pb
