Pre-Contest Stack

I’m getting ready for a show (20 weeks out) and would love some advice regarding a stack using the gear I have access to. Deca, D-Bol, Cypionate, and Clenbuterol. Also, I know Poliquin recommends the types of workouts described in “Manly Weight Loss”, but does “Special” supplementation change the rules. I spent all winter putting on mass and I really want to hold on to as much as possible, if not put on more during my prep. 5’6", 210lbs, 20% Bodyfat, 18" arms & calves, 35" waist(for now), 29" legs. Thanx, T-men!
