Disclosure
How we decide what goes on the site, in what order, and how links to other sites work.
Last updated Oct 23, 2026
The rules a listing must meet to get on the site are on How we choose.
Never ranked for money
No provider, brand or clinic can pay to be listed on Build My Longevity, to be left off, or to get a better position. What we list, the order it appears in and what we say about it are decided only by the published facts.
Comparison tables are grouped by type (for example memberships and one-off tests) and ordered by price inside each group. That order is not a ranking, and we never name a "best" option or a winner.
Links to other sites
Where we link to a third party's website, that link may be an affiliate link. If it is and you buy something, that company may pay us a fee. The price you pay is the same either way.
Whether a link is an affiliate link never changes which providers or products we list, the order they appear in, or what we say about them.
Australia
We never use affiliate links for Australian clinics or for supplements in Australia. Links to them are always plain links.
The Australian site has its own disclosure: buildmylongevity.com.au/disclosure.
How we check
- From the source. Every price and fact is checked against the provider's or brand's own website, not a search result, press release or reseller, and copied exactly as published.
- Dated. Each price carries the date we checked it. Treat that date as an expiry, not a guarantee, and check the provider's own site before you buy.
- "Not stated" means not stated. If a provider doesn't publish something, we say so rather than guess.
- No "was" prices of our own making. We only show a price drop when we recorded both prices ourselves, with dates.
- No reviews or star ratings of our own. Where we show an outside rating, such as Trustpilot, we name the source, the score, the number of reviews and the date we checked it.
- Claims are the brand's. Where we repeat what a brand says, we label it as theirs.

Sponsored content
If we ever publish paid content, it will be labelled "Sponsored" and kept separate from our comparisons.
Not medical advice
Build My Longevity compares prices and published facts. It is not medical advice and doesn't recommend a test, product or supplement for anyone. Talk to your doctor about what's right for you.
