I believe attack is ATD and really not ideal for pct. It can be hard on sex drive and actualy lower E too much. I would say if you cant get nolva, just search the net it is available. Other wise I have had good results with 6 oxo and N1T by universal. This PCT has always worked well for me. What are you coming off of, like Donky Kong said this is not a good idea for a full blown cycle of roids.
