20mg of nolva/clom? is that nolvadex or clomid?
Taking nolvadex can make your nipples harder, when I had gyno If I used 40mg Nolvadex a day my nipples would harden up. Gyno, when emerging usually makes your nipples feel sore (like the've been rubbing on your t-shirt) and puffy.
I would advise taking .5 mg Adex twice a week on this cycle, which should, under normal circumstances be sufficient to prevent any gyno. I used 1mg adex a week on 800mg test, with existing gyno and had no amortization problems.
