I will go against the grain and take a different path, if you are adding this to a base of test I wouldn't exceed 200 mg of NPP per week and run it longer than you were going to run at 300 mg. I'm conservative but the best and most accomplished coach I know usually adds 200 mg of deca to multiple programs for different ages. I know people take large amounts but I will always defer to people who know more than I do.
If you can't grow off a base of test and 200 mg of deca/NPP something is wrong. Your diet/training/rest is off. You can bulk or cut on those two compounds depending on your diet.
