Beginner cycle advice.. Any input is appreciated!!!

[CMonis1]

Hello all...
I'm 5'9 165. I've been lifting for almost 5 years seriously and have started to plateau in the last year or so. I've decided to put a nice stack together going into baseball season and thought I'd ask my questions here. I'm looking for some advice on a good lean mass stack for a beginner. I've taken a 12 week cycle before of sustanon 250 at 1 cc to 1.5 a week and that worked out well. I've been researching here and other places for other good beginner cycles and came across another 12 week cycle.

week 1-6 Dianabol 25 mg ED
week 1-12 Test E 400mg
week 13-15 let test clear out
week 16-18 Nolvadex 40 mg down to 20 taporing off

All in all, is this a good cycle? Should I take any anti estrogen or liver protection while doing this stack? Is there a better cycle for someone in my situation? Is the D-bol going to give me a poofy look taking away all my definition and abs?

I know this is a lot of questions, but I feel that the knowledge is only for the better.
Thank you all in advance!!!!
