They are the same active ingridient so what it boils down to is price and ease of use. There are a few variations on the liquid floating around, 4mg/ml and 1mg/ml and then there are the .25mg tabs and the 1mg tabs. Since anastrozole has a 50 hour half life it could be taken eod and cutting the 1mg tabs in half is no problem. I get 1mg tabs for $3 each. The 1mgml liquid ofr $3-4 per ml.
