I preferred your NPP mast combo that you were thinking of. I can be substantially leaner while putting on good amount of muscle with NPP+DHT.
How much more size do you or trainer feel you need? I don’t like Deca for this, if for any reason other than the half life being too long to risk clearing it. 16 weeks, and I’m no expert, but I’d transition over to short ester everything personally.
NPP/Mast 3 more weeks of drol or SD
6-8 weeks out Tren Winnie Var
Just my thoughts, you know whay more than I about competing just my 0.2
