I've read that Nolva will both "dry" a cycle and prevent gyno while on cycle. However there are conflicting posts that say it is better to "control" estrogen with something like Letro. I think Dr.D brought up some good points in a Nolva/PCT thread saying how bad Nolva is for the liver. So all those things should be taken into consideration. I would just stick to Nolva, but thats me. Maybe someone else can chime in, cause I don't know too much about PCT other than Nolva and Clomid.
