I don't actually build any AD on Nasus. I have a rune page that I use for a lot of ADCs which has armour pen reds and quints for a total of 19 (if I recall correctly) armour penetration.

My reasoning for this is that Nasus' main damage source is his Q, and because it technically doesn't really scale with AD, the armour pen will give it better overall damage.
