Obviously you don't if you're considering running Deca and Dbol. And that's aside from the nature of your purely noobish questions. Before you even post any threads you should know why running Deca and Dbol is a bad idea. I'm sure you've been lifting a long time but that doesn't mean jack about your AAS knowledge.
But, it's painfully obvious that you're going to run a cycle anyway regardless of your level of research so I'll just tell you that you need to run Testosterone. Stay away from a progesterone like Deca unless you have a specific reason for wanting it to run it over other compounds. Deca will shut you down harder than most other compounds and you can read all day horror stories from noobs like you taking forever to recover and screwing themselves up real nice. On top of that I doubt you'll know what to do or be prepared if one day you're able to squirt milk from your nipples.
Just run Test, Dbol (if you are absolutely set on running it), and an AI (I'm not telling you which one or how much, you can research it yourself) because not only will you bloat like crazy and probably put on some fat thanks to the estrogen, but you're risking gyno big time without it. There isn't much point to adding Dbol unless you want to "jumpstart" a cycle with long ester(s). For example, if you run Test-E it would make sense to take Dbol for the beginning weeks it takes for it to start kicking in. If you run Prop, there really isn't a whole lot Dbol would do for you that a higher dose of Test couldn't - and you won't have to worry about your liver.
Don't bother with people who recommend the "bread and butter" stack for you first cycle or any multi-compound stacks. Since it's your first run you'll grow like crazy on just Test alone and adding other compounds really won't add a ton more in the way of gains, it will just complicate things and increase the potential for side effects. Like I said, you really don't need the Dbol but it sounds like you have it already and are set on eating those pills.
Also, running Test with an AI will probably give you the least amount of sides of any cycle. You should know that already if you think you are anywhere near ready to run a cycle. There is a reason why solo Test 400-500mg/week is the "standard" cycle recommended to beginners.
On top of having very low sides, it is a very simple cycle. If you run hCG the whole time to keep your nuts full sized (google the SWALE hCG protocol), keep your estrogen in check, and run good PCT, you'll likely bounce back extremely fast and have very, very low risk of hurting yourself.
