Its 2 completely different things bro. Dbol is Methandrostenolone. and NPP is nandrolone (deca) but with shorter ester so it hits faster than regular deca. With my experience you won't feel any huge boosts in anabolic activity with NPP unless your in the 500mg a week range. If your taking it just for joint relief, as deca tends to lube up the joints then take the 300 mg range.
Kinda confused what your after with this one. EQ looks a little high in my humble opinion, I'd reverse the dosages. 750 ENAN and 500 EQ. Stick with the Dbol for a couple more weeks then go off of the orals. Or get injectable Dianabol.
