No they are not the same. If you do not have Clomid (which you should) you can run Nolv. I prefer to take both. Typical Clomid is 5days at 100mg then 7days at 50mg. You can take nolv inconjunction with clomid to help out with your end cylce "crash", but I prefer to run it after the clomid and prolong the state of being "anabolic".
I think there is a locked thread on the technical info b/t the two.
