You can go as high as 80 mgs a day...although probably not necessary. 40 mgs a day in divided doses has been shown to be effective. But, since you already have gyno, and you're still on cycle, you should continue the nolva throughout your cycle. You will most likely also have to continue your nolvadex for up to 3-4 months after cycle at 20-40 mgs daily in divided doses to see your gyno disappear. Even then, it's about 70-80% chance it will be eliminated.
