Summary
Most claims are pricing/marketplace-advice and do not appear in the provided FDA label excerpts; therefore they are unsupported. A few drug/product identity and delivery-system descriptions are partially aligned with label excerpts (estradiol vaginal system; delivered over ~90 days), but overall alignment is poor because many statements cannot be supported by the supplied prescribing information.

Primary Issue
Most statements are not found in the provided FDA label excerpts; pricing and consumer-shopping guidance is unsupported by prescribing information.
