After doing it the natural way, at what age do you think a woman should take it? At what age does it really start to decrease?
I am NOT a endocrinologist. But the best way to decide is to get bloodwork and check your IGF levels. If they are below what a healthy young adult should be at, I'd say youre a prime candidate for HRT to optimize your levels. This rule of thumb can and should be used for ANY medical decision. Get your bloodwork done people! I want to be in the supra physiological range for IGF and free test, so HRT is a very good thing IMO.
Anecdotally, I like what the ofher posters are recommending, between age 35-40.
