proviron will block estrogen production so if you take it throughout your cycle then you dont need to run nolva during your cycle. BUT after you are finished w/ this run you should consider getting something to stimulate LH so that you get up and running again, proviron will not be able to do this, it will help w/ your sex drive and erections but it willl do nothing in the way of restoring your HTPA. clomid is my favorite for this restoration period but a lot of people think nolva is better, it is all about what works for the individual. Having said that, I know it is hard to find in australlia so I would llok into getting some tongkat ali, a good concentration and taking 2x the recc dosage
