THE PUBLICATION

How we research and compare

A clear account of how this site works.

What goes into a review

We begin with the official product or provider page. We record the identity of the product, its format, publicly described ingredients or formulation, price basis, any stated commitment and what is included. We then look for primary medical or regulatory material where a claim requires context. A provider’s own marketing is not independent clinical evidence.

Prices need a denominator

A first-month discount, bottle price, vial price and recurring monthly charge describe different purchases. We retain those distinctions. Where the source does not establish a quantity, renewal schedule, eligibility condition or all-in total, we state that uncertainty. Prices are checked on the article date and can change. Our tools calculate from visible catalog facts or your own inputs; they do not fill missing details with assumed treatment schedules.

What we do not score

We do not invent star ratings, patient outcomes, satisfaction scores or clinician credentials. Our provider order is not a clinical ranking. CoreAge Rx is featured through a commercial placement selected by the publisher. The alternatives receive their own sourced reviews and the reader can compare them by the relevant product details.

Claims and evidence

An ingredient study does not automatically validate every finished formula containing that ingredient. Different routes and formulations should not be assumed equivalent. Compounded prescription products are not FDA-approved. A treatment’s historical regulatory status does not establish the status of a current compounded preparation. Research limitations are part of the review, not a footnote to be ignored.

Keeping the record useful

Each review links to its underlying material so readers can check the source. We do not claim that provider terms are monitored continuously. The date on an article is the latest editorial verification date. If an official page and our summary differ, confirm the current terms directly before purchase.
