How long are you planning to cycle? M18 is right as always, you could also add 400mg of winny the last six weeks. Two tissue builders are better than one. If you're gonna do the D-bol DON'T do the winny. Way too harsh on the liver.
If you want to add just one more thing to that cycle,I would add winny for the last 6 weeks.It will harden you up and help you keep your gains.Just my opinion.
Go with winny. It'll help with progesterone sides, and you won't get the joint pain usually associated with winny because of the deca. Deca and winny were made for each other, throw in a little test and you got a perfect cycle IMO.
