nandrolone is nandrolone... yes they are different release rates, but the metabolites linger for about the same time...
the reason you do get a bit less sides is because with a prop ester you generally inject eod, so you get more stable blood levels... im speculating that if you pinned deca eod using comparable dosages, then your levels would not drop and peak as much thus yielding less bloat etc...
i do prefer short esters myself though due to the fast start, but npp still did bloat me some; never ran deca so the verdict is still out there...
good for bulking and powerlifting imo...
