I wish I had a good answer. The two Physicians at Defymedical.com, Dr Crisler and Doctor Saya both use this protocol. I remember both clearly saying progesterone is not a male hormone...lol...I think they are weary it in men. They never mention vitamin E at all. I could always go it on my own ofcourse, ultimately it's my body. I just want to give my body the best chance to succeed and give a nice healthy T level with controlled estrogenWhy is he so hellbent on the clomid? There are so many other ways to regulate estrogen. Why would not progesterone and/or vitamin E be just as effective without the serious estrogenic side effects of clomid in the brain and liver?? The term SERM is just a marketing gimmick, these chemicals are still estrogens.
