Yes, HRT should be done on "high" levels so it actually works, Its often prescibed in a crappy way, drop of estrogen and boatload of T blocker and that's it. It wont work much like that, but the moment its done correctly with high and stable enough levels and expanded with progesterone... It becomes very different.
No herbs alone can do that because that's simply not how it works. This is some kind of mythical cope that guys can imagine they're doing something comparable with herbal routine. It just doesn't work like that, NBE can be ok at what its supposed to do, but on its own, its never as good.
