One of the problems with trying to research hormones is that studies can be not specifying whether they are using bio-identical or the patented kind. And it makes an enormous difference; I've seen papers where all the bad effects (like that big HRT study that shut down its use) were all done with the artificial, patented, kind.

While OTC bio-identical progesterone was very helpful, and has no tumor growth indications at all. It balances out the other hormones, which we get from our plastic-laden environment.

It's all about growth hormones; and yet fasting increases HGH for a beneficial, and anti-cancer, effect.
