The typical deca + orals stack is with dbol over the first four or five weeks and then winny to see out the cycle going one or two weeks past the last deca shot.
I would use d-bol with the deca. Besides the fact it is a highly regarded cycle in most bb books (Anabolics 2004 etc.) most doctors wouldn't recommend deca and winny with out test, the levels get too low and shut you down too hard. IMO
