Longevity Benchmark is an independent editorial site covering the direct-to-consumer longevity industry — biomarker platforms, wearables, sleep tracking, and the supplements that end up in the same shopping cart.

Why the site exists

The category grew faster than any way to compare it. A single label, "longevity platform," now covers a $499/year mail-order blood panel and a $19,500/year clinic membership. Both market themselves with the same words: comprehensive, physician-led, personalized. Neither phrase has a fixed meaning, and nothing on a pricing page forces one.

Three specific problems make cross-shopping hard. Advertised prices exclude the draw fee, the consult, the retest, and any prescription. Biomarker counts are quoted at the maximum available rather than at the tier being sold. And the word "physician" covers everything from an asynchronous message review to a scheduled video visit with the same clinician each quarter. Our job is to publish those distinctions in a format you can act on in a few minutes.

What independence means here, operationally

Independence is a set of rules we can be held to, not a claim. These are the ones that govern every page.

  • No free memberships or products in exchange for coverage. Where a subscription is needed to reproduce a signup flow, it is paid for at the public price. A platform cannot buy its way onto the site or off it.
  • Affiliate relationships are disclosed on the page where they apply — not only in a site-wide footer. They do not affect scoring, ordering, or category placement.
  • No tie-breaking for sponsors. When two products genuinely tie on a criterion, the page says they tie. An advertiser relationship is never the reason one name appears above another.
  • One rubric, applied identically. Every platform comparison uses the same nine criteria in the same order with the same wording. A rubric that changes by page can be shaped to fit whichever product the page is about.
  • Stated ordering in every table. Lists of three or more platforms are alphabetical by default, or ordered by a key the page names explicitly, such as price. Nothing appears first without a reason printed on the page.
  • No editorializing about relationships in either direction. We do not claim partnerships we do not have, and we do not disparage platforms to appear tough. Trade-offs come from the rubric, not from tone.

Who this is for

The reader we write for has already decided that measurement is worth something and is now facing a purchase with no reliable comparison. Usually that is one of four situations: a first panel and no idea what to order; normal labs and symptoms that persist; a specific pattern such as low free testosterone with high SHBG; or the retirement decade, where the priority shifts from optimization to keeping functional independence. The audience guides are organized around those four.

The site is not written for clinicians, and it is not written for people looking for a protocol to follow blindly. Most pages end in a decision framework rather than a recommendation, because the right answer depends on inputs only the reader has.

What we do not do

  • No medical advice. This is editorial coverage of health products. Nothing here diagnoses a condition, prescribes a treatment, or substitutes for a clinician who knows your history and medications.
  • No diagnosis or interpretation of your results. Pages state population-level target ranges. A target range is not a reading of your panel — a result means something different at 35 than at 65 with a family history.
  • No ranked "best platform" verdict. Products serve different constraints. Pages name which reader a product fits, and give the opposite guidance equal weight.
  • No supplement or device sales. We do not manufacture, white-label, or resell anything reviewed here.

Accuracy and corrections

Every price is date-stamped, and pricing across all reviewed platforms is revisited at least quarterly, because entry tiers in this category change several times a year. Every meaningful change carries an updated date on the page. If a price, feature, or fact is wrong, tell us and it gets corrected — we prefer visible corrections to quiet edits.
