2.2mg per pound of body weight. If you weigh 200lbs, take 440mgs a week. I remeber reading that in Anabolics 2002. It seems to be a good rule of thumb for someone who has done a few cycles.
I have used QV deca with good results with test.
For ROCJUICE, I would get something to stack it with, like test or dbol. What is your cycle history?
