I think for your first cycle you should go a bit lighter on the test and perhaps a bit heavier on the dbol. I would structure it like this (if you are set on those steroids).
Week 1-10 Test E 500mg/week
weeks 1-2 dbol 20mg/ed
weeks 3-6 dbol 30mg/ed
weeks 1-10 nolva 10-20mg/day
Then your nolva/clomid PCT can still be used as you suggested, I prefer running nolva on cycle to arimidex!
DEFINITELY DO NOT run so much arimidex to start bro!! start with 0.125mg EOD DEFINITELY NOT 0.5mg… you may end up needing 0.25mg eod but I doubt you will need more than that, and nolva is a better option regardless in my opinion! Adex can really kill gains if you are using even SLIGHTLY more than you need!
IF you are open to a slightly different cycle, this is what I ALWAYS Recommend to beginners! It was my first cycle and a few of my friends ran it first as well!
Weeks 1-12/14 Test E 400mg/week
weeks 1-12/14 EQ 600mg/week
weeks 1-12/14 Nolva 10mg/day
You could add dbol as I outlined above but this should be more than enough for a first cycle!
People really under estimate steroids… I guarantee you could get very noticeable great results with only 400mg test E per week and nothing else! I definitely would recommend this EQ stack though, its a great run!
