Yes, it would be very effective. Proviron will prevent aromatising, and nolvadex will block the estrogen receptors. Kind of a double protection. You could take 25mg of prov and 20mg nolva every day. The only problem is that proviron will diminish the anabolic effects of the juice, because it also acts like a steroid and blocks androgenic receptors. So I would cut it's use to a minimum.
