Bro it will only be water that is all. I really do not subscribe to losing gains on Nolva theory. Yes it will make you drop the water which can have an effect on strength if using a med like Dbol but the water will come off when you stop using Dbol anyway and you will keep real gains that are underneath.
10mg of Nolva ED will keep some of bloat down. If you see signs of gyno then take 20-40mg ED until symtoms subside.
On 30mg Dbol ED the IMHO you need the bloat for the additiona strength. The Nolva will reduce this with the water. The bloat will go when you stop the Dbol
i have been using (well finishing up using) 40mg nolva ED for a 6 month cycle of GH/Test/EQ/Fina/Winny/Slin. no anti-E's. seems to be working fine. i had pre-existing gyno, so i figured i'd better take it for the duration and afterwards too. i'm on NRT (nolvadex replacement therapy). lol. seems to keep me leaner and not as bloated as i figure i would be w/o anti-E's. but who knows, we are all different.
