Wintrol kills your joins something terrible and what it does in drying you out ,will most likey come right back. It's pre contest prep gear or a good finisher..Poor choice for a stand alone cycle imo.Plan out a decent cycle before worrying about pct.
I ran Winstrol by itself a number of years ago and when doing heavy squats, it sounded like my femur was grinding against my tibia. So I belive now that Winstrol should be run with something like Deca. As to your question, Nolva will work.
