I personally think at the end of the day.. you would be much happier running dianbol. When you are on anadrol you will turn into superman real quick.. but when you go off it all changes quickly. You will lose a lot of what you gain from drol. I am not one to get too concerned with side effects.. because there are precautions you take to limit those.. but, with the case with anadrol, i think the side effects out weigh the benefits. But.. it is up to you.
I would not run drol more than 4 weeks.. Usually would run it to kickstart a longer cycle. Since you only want to go 6 weeks I think the only real choice you would have to stack it with is Test Prop.
