Ok first off, you should probably have some nolva on hand, because you are dealing with a PH. Novadex may not be sufficient for pct.
How tall are you by the way? At 157, I definitely think that you could have gained at least another 20lbs naturally. And at 157, if you were eating 6k-7k in calories, then you would blow up like crazy. I find this very hard to believe that you are taking in this many cals. IMO, I also dont find any benefit in starting your PCT while your still on cycle.
As for your question. You dont want to lower your cals during pct. Keep your cals normal (whatever it really is) and your volume low. I wouldnt suggest doing any cardio, but if you do any, keep it minimal.
