At 300 to 400mg a week of test I wouldn't do any nolvadex you probably won't need it. Have some on hand though if you start to get symptoms of gyno. Also you could do .5mg of l-dex eod to combat bloat and other estrogen related sides. The nolvadex could be saved for your PCT.
I agree with liftsiron, you most likely will not need nolva until post cycle. If you start seeing gyno symptoms then you can start taking the Nolva ...not likely @ lower doses.
