I plan to blast deca @ 900mg p/wk solo for about 12-16 weeks or so as the main part of my bulk cycle. Now, I understand that it takes quite long for deca to clear the system, so I was thinking that I cut off deca after 12-16 weeks, and after a week or so after my last deca pin, I add NPP for about 1 month @ 300-600mg PW until deca clears system, and then cut NPP, and seeing as NPP clears a lot quicker there will be less total time where I will have minimal exogenous hormones as well as minimal endogenous hormones in my body.

Point 1: Please don't advise me to run test. I am intentionally avoiding testosterone for this cycle as I have valid reason to believe it will do more bad than good.
Point 2: I still haven't decided whether I will come off completely and stay off until my cut OR if I will cruise on something low dose and then blast again for my cut. This depends on how I feel I handle AAS in general, as well as financial standpoint (as this is the first time I am ever running gear).

Please give justification for any suggestions made, whether it be anecdotal or empirical.
