The HRT Index · Research & Reference
An independent research library for menopause and hormone therapy
This is the reference section of The HRT Index — a set of verified, plainly sourced data assets on menopause hormone therapy and its alternatives. Each entry is dated and maintained as a public reference. It is deliberately kept separate from the rest of the site: no products, no promotions, nothing to sign up for. Just the facts, organized to be cited.

About this section
How the research library works
Every asset here is built from primary sources — FDA prescribing labels, regulatory notices, and peer-reviewed literature — and carries a visible “last updated” date. We revisit each reference on a regular schedule and revise it when the underlying facts change. Nothing in this section is sponsored, and nothing links out to a product or a paid placement. If you spot something that needs correcting, that is exactly the kind of note we want.
Reference material only. This library is not medical advice and does not replace a consultation with a licensed clinician.
