pct is DEFINITELY needed. If you have the nolva, use it. No reason for it to go to waste. I'd run pct at 20/20/10/10 or if you want to go a little more old school you could go 40/40/20/20 something along those lines. You're going to get a lot of people saying use sustain alpha; I have never personally used it, but from reviews and whatnot it seems to work very well. You will be fine with just using the nolva, but it wouldn't hurt to throw in some sustain alpha as well.
