Endocrinologists are terrible at knowing what hormone ranges are good for your age and sex. As a man with thyroid problems, I am thoroughly disabused of the idea that most endocrinologists have any clue what they're talking about. Certainly, for a middle aged women, must can put it together, but barring that, you're better off on facebook groups.

Seems like a terrible resource. Much better would be blood work at your PCP (and a possible referral to an endocrinologist).
