The synergism of both Nolva and Clomid for PCT is great. You should be fine with just one or the other though. If combining the two of them, there is no need to full dose both of them when doing so. I personally like to run Nolva a couple of weeks past the clomid, for the extra protection it provides (against potential gyno).
Having said that, anybody who is cycling (but especially with aromatizable compounds) should have Nolva or Raloxifene in their cupboard to deal with gyno or gyno-like symptoms that may arise on cycle. May times an AI is not enough, even when drastically lowering estrogen with said AI. The best way to deal with on cycle estrogen issues, that may cause a lump to form behind the nipple, is to lightly use both a SERM and an AI to relieve the issues. Obviously the compounds that are run on cycle will help to determine appropriate doses of both.
