I have struggled the past few weeks dialing in my estrodial and found this article very helpful in getting mine where i need it. He says that estrogen is the hardest hormone to control in the male body and man do i agree. Its very temperamental and hard to know if your high or low but he points to some really good ways to tell that will help you dial it in.
One thing that sucks about estrogen, is i get my blood tests every 6 months. Well a lot can change in-between visits and, as he states, estrogen is constantly changing. Some weeks you might only need 1/2mg of Adex a week and other times you might need to bump it up to 1mg a week.
All in all, good info.
