There are many very effective synthetically produced ERT's available. According to the write-up I have, a few are: Estradiol Transdermal System, Estradiol tablets, Estropipate, Estrone and Estrace Joan Cutchins [log in to unmask] P.S. I apologize for being late answering this thread, I haven't logged on for a few days.
