There are other places that support informed consent, but PP is the big one. I’m not sure what you can get beyond HRT, but for some folks, that’s all it takes to get to a point that they feel like going on.
I’m also not sure if you can dictate what you want for HRT. If you local endo wants you on spiro and E, but you’d prefer progesterone, can you do that? Or decide on dosage levels? The HRT choice is not set in stone, and PP might give more options in that regard.
