Editorial methodology
Longevity Costs is a price-research directory. Methodology is part of the product — not a buried legal footnote. This page explains what we measure, where data comes from, and what we never claim to do.
Provider scores reflect information quality and accessibility — not clinical outcomes. A high score means a buyer has more and clearer information before contacting the provider. It does not mean the provider is medically superior.
Pricing visibility (0–20 pts)
Providers that publish clear starting prices or price ranges score higher. We award additional credit for price-per-unit clarity (e.g., per session vs. per month vs. membership), price-range transparency, and lab-testing cost disclosure. Providers that require a full consultation before sharing any price receive limited credit in this dimension.
Service breadth (0–20 pts)
We track which treatments each provider offers across: NAD+ therapy, TRT, HRT, GLP-1/weight loss, IV therapy, peptide therapy, lab testing, and full-stack longevity memberships. Breadth is scored relative to the provider's stated positioning — a TRT-focused clinic is not penalized for not offering IV therapy.
Telehealth and location access (0–15 pts)
We record telehealth availability, how many states a telehealth provider serves, and whether medications are shipped directly. For in-person providers, we track location count and whether they serve markets beyond their home city. Accessibility directly affects a buyer's real options.
Lab-testing context (0–15 pts)
Lab work is a significant hidden cost in most hormone therapy programs. We note whether baseline and monitoring labs are included in the program price, whether the provider partners with a reference lab, and how often monitoring is required. Providers that clearly disclose lab requirements score higher.
Transparency score (0–15 pts)
A composite 1–5 signal derived from: whether prices are publicly listed, how clearly program structures are described, whether membership requirements are disclosed, and whether the provider's website communicates what is and isn't included. A score of 5 means no friction before a buyer understands what they would pay.
Editorial quality signals (0–15 pts)
We capture each provider's headline positioning, stated best-fit use cases, known limitations (cons), and care-model description. Pages where provider data is too sparse to generate useful comparisons are marked as lower-quality until data improves.
All data originates from publicly accessible sources. We do not accept provider self-submissions as editorial fact without independent verification.
Provider websites
All pricing data originates from providers' own publicly accessible websites, pricing pages, and marketing materials. We do not use estimated, leaked, or unpublished price data.
Telehealth platform pages
For telehealth providers, we check platform pricing pages directly, including program enrollment flows where pricing is displayed before signup. We record the lowest available starting price for the most accessible plan.
Date stamping
Every provider record is date-stamped when prices are verified. The 'Last updated' date on each page reflects the last time pricing was reviewed. Prices change; always confirm directly before enrolling.
Reader corrections
We incorporate corrections submitted by readers who identify outdated or inaccurate pricing. If you spot an error, contact us at hello@longevitycosts.com.
Rolling price checks
Provider pricing is checked on a rolling basis as part of routine directory maintenance. High-traffic providers and telehealth platforms — where prices change most frequently — are prioritized.
Last-verified dates
Every provider page shows the date pricing was last verified. Treat older dates as a signal to confirm pricing directly — not as evidence that prices are wrong.
Reader corrections
We investigate and correct errors reported by readers within a reasonable timeframe. Contact hello@longevitycosts.com with evidence and we will review promptly.
Not every page the directory can generate is automatically indexed. We run each programmatic page through an internal quality gate that evaluates word-count depth, unique data points, provider count, pricing signal count, and duplicate risk. Pages that score below the threshold are either excluded from the sitemap or marked with a lightweight notice acknowledging that data depth is limited.
This means some provider service pages, location pages, or comparison pages may show a "lighter page" note when the underlying provider data is not deep enough to generate a genuinely useful comparison. We believe showing the limitation honestly is preferable to faking depth.
