That's a nice recipe for bloat.
Deca needs to be run for a fairly long time, at least 10 weeks, preferably more.
Dbols are nice to kickstart at the beginning - I personally like 20mg a day because you get less sides, but many people prefer 30-40mg ED because of the size and strength it gives. You should probably use it for 4 weeks at the start.
I would definately suggest some testosterone as well. Designer steroids are meant to supplement testosterone while cutting back on the sides - so instead of taking a gram of test you can take 500mg test/500mg deca, and hopefully you'll have less sides.
Be aware, finally, that deca will shut you down particularly hard, so you really need to nail your PCT and learn how to use HCG during cycle (250mg 2x/week tends to be the preferred method on THIS board).
