npp and deca have similar esther weights so your getting the same amount of active drug but npp is never dosed above 100mg while deca is usually 200-300mg and both are usually similar in price.
i use a mix blend and i dont get much water with deca unless i use test with it.
both are great for a thicker look
I dunno how you have similar ester weights (without me bothering to look it up) when one ester takes 15days to cleave of and the other takes 2.
if I didn't get tired of pining 3x days a week, I'd prefer to run 3cc of 150mg/cc npp year round.. but I switch to deca (at about 4x the dosage) for half the year.
appearance-wise, I prefer npp.
shit... speaking of npp... I still have a loaded 3cc pin with 450mg sitting in it. fuck, I'm shooting first thing the morning. lol ...I totally forgot about it.
