Because there havent really been any real studies of users on this drug most information on it is speculation and theory. I think when doing the 2wk on, 2weeks off w/nolva then 2 weeks on again cycle the nolva is used mid cycle just to help the boys a little bit. We had this discussion at anabolic minds and i think most agree that it will shut you down with 2 weeks of usage so its kind of just taking extra precaution. Since no one knows how much it will shut you down they figure it doesnt hurt to use some nolva between the two week cycle.just like kidrok said its cheap insurance. to answer snickers question, most people are reporting kept gains of anywhere from 8 to 15lbs after the 2on 2off 2on cycle with pct. this compound kicks ass!!
hope i didnt confuse anyone.
