How we work

WeighLab publishes cost models and value rankings, not clinical guidance. Every price, state-coverage claim and formulary detail is tied to a provider's public disclosure or an official manufacturer price at the time of review; every efficacy or safety statement is tied to peer-reviewed research or official labeling.

Facts vs. judgment. Provider facts are sourced and dated. The Cost-Efficiency Index is our editorial judgment, produced by the same six-factor model for every provider on the same published rubric.

Independence. WeighLab is reader-supported — assume any provider we list may compensate us — and we keep the Index independent of that; a commission never moves a score. See our disclosure.

Who writes this. WeighLab is a cost and data desk. We are not clinicians and we do not practice medicine — what we publish is consumer cost analysis, and every clinical statement on the site is carried by a named primary source rather than by our own authority. Where we cite research we cite the study itself: authors, journal, year and its PubMed identifier, checked against PubMed as we write rather than recalled. Where we describe a drug's approval status or labeling, we cite the FDA record. If a question needs a clinician's judgment rather than a source, we say so.

What we check, and how often. Provider prices are read off each provider's own published pages and stamped with the date we read them — that date is printed on the review, so you can see how fresh a figure is instead of assuming. We re-screen the whole provider roster against the FDA's warning-letter register every month and disclose what we find on every surface that profiles that provider, whether or not we earn anything from them. We sweep every outbound provider link on the same cadence, so we are not sending you to a company that has gone dark.

Corrections. Telehealth pricing changes constantly, and a provider changing its own price is a re-verification, not an error on our part. A claim that was wrong when we made it is a correction, and we publish those — what we said, what it says now, and how we established the right answer — in a public corrections log we do not delete from. Flag anything that looks out of date and we will re-verify it.
