Seeing as you already have the gear…
Testosterone and nandrolone is a great match for a size stack.
The esters you have chosen are not the greatest match, but it wont make a difference to the end result.
I like it overall. I would use letrozole/arimidex DURING the cycle, as you DO need some estrogen control as bone mentioned… i PERSONALLY would choose letro as it is suggested it has some anti prog effects… but for a newb it would be alot easier and simpler to use arimidex (0.25mg EOD-ED), and TBH it is an unlucky day in bodybuilding when a man finds deca an intolerable drug as far as gyno is concerned (but it has been known… prolly fake mind you)
Seeing as you are using a stasis taper there is no need to stop the deca 2 weeks before the cycle end… both finishing at the 10 week mark is fine as you’ll have 4 weeks (preferably 6 with the Decanoate ester) for hormone levels to normalise.
As for your taper - again, i can only say what i would do in your shoes knowing what i do.
That would be to use the nolva as you start the taper, tapering off the adex during the stasis, and beginning the nolva to catch the remaining estrogens…
I’d taper the test (injecting daily of course) simply - 80/60/40/20… and continue the nolva for a week or two thereafter.
For an alternative opinion it may be of interest to you to know that i actually wouldn’t use the stasis taper at all for a first cycle, and would definitely use a little caber and HCG also… but that is a different post.
