I like adex much better than nolva for estrogen control during cycles. I have less bloat and can get away with .25mg a week of adex, whereas it would usually take 20mg of nolva. I always think that less is best when following any drug related cycle, as long as the effects are comparable.
I have less bloat, thus better endurance and better training sessions.
As for PCT, I use adex for the first week, along with nolva and clomid. Then, swap to clomid and nolva only for 4-6 weeks (depending on cycle lenght). I am always able to maintain my gains, I usually drop about 5-8 lbs of water once I conclude the cycle.
