In my educated guess, I dont have lab results, just experience,
I have used dbols as part of many cycles, whats good id=s you see great gains in strenth, water retention always seems to be a problem for me, however the past few cycles that i have done along with N-dex, i have noticed significant decrease in water retention, with such a short cycle i think that you should be fine, this is just my experience tho, always by weeks 3 i notics some retention however, my past cycles i havent noticed any, so IMO u should be fine w or w/o, just make sure to limit things such as socium that help in aiding water retention....jus imo...hope it helps bro
