Every cost on longevitycost traces back to a primary source and a date. Here is exactly how we gather, grade, and present the numbers, and what we deliberately leave out.
We start from primary sources: the provider's own published price page wherever one exists. We cross-check against independent reporting and, for figures that move, against more than one source. We do not quote a price from a single unverified blog and present it as fact.
Each figure carries one of four labels so you know how much to trust it:
If we cannot stand behind a number, it does not go on the site as a fact. Examples we currently flag rather than state: Fountain Life's membership price (hidden), the often-quoted biological-age-test figure (unverified to the current product page), and a viral Blueprint monthly figure that traces only to a social post. Honesty about what we don't know is part of the service.
Every item in the Estimator carries a two-part badge. The first part says what the FDA has actually cleared or approved: a scanner, a drug for a specific disease, or nothing at all. The second part says the status of the use you would be paying for, such as off-label prescribing, screening that a professional body does not recommend, or a test nobody has validated for clinical use. A cleared scanner is not an endorsement of screening healthy people, and an approved drug is not approved for every purpose, so we never collapse the two into one word.
Each part links to a primary source: FDA databases and pages, the relevant professional body, CMS, or a peer-reviewed paper on PubMed. If we cannot verify a claim, the badge says "not verified" instead of guessing. Regulatory sources were last checked in October 2026.
Longevity pricing changes constantly through new tiers, acquisitions, and promotions. We re-check figures periodically and date every page. If you spot a price that has moved, it probably has, verify with the provider before paying.
