What This Site Does
We help you decide which longevity company is best for you.
These companies all sound alike in their ads — but a $499/year mail-order blood panel is not the same product as a $19,500/year clinic membership. Prices often leave out the draw fee, the doctor visit, the retest, and the prescription. Biomarker counts are often quoted at the biggest panel available, not the one you’re actually buying.
We put every platform on the same checklist, in the same order, with the same wording — so you can compare them without the marketing spin. If two products tie, we say they tie. Tables are sorted alphabetically or by a stated key, never by who paid us.

Longevity Platforms
Twelve platforms priced side-by-side on one rubric, from $499/year mail-order panels to $19,500/year clinic programs — with the costs that appear at checkout.
Biomarkers
ApoB, fasting insulin, Lp(a), SHBG, hsCRP — optimal targets rather than lab-normal ranges, grouped by system, with retest cadence.
Wearables
Apple Watch, Garmin, Oura, Whoop — what each actually measures, where the readouts disagree, and which metrics are validated.
Sleep
Deep sleep, REM, core sleep, recovery score — decoded in the vocabulary your wearable uses, with the numbers that matter.
Supplements
Evidence-ranked buying guides with effective doses, label red flags, and the five supplements you should test for before taking.
By Audience
Beginners, busy professionals, men over 40, retirees — the priorities, biomarkers, and budgets that fit each life stage.
The Standard Rubric
The same nine rows appear on every platform comparison. Only the cell values change. That is deliberate: a rubric that varies by page can be shaped to favor whichever product the page is about.
| Criterion | What it captures |
|---|---|
| 1. Annual price (entry tier) | The number you pay if you never upgrade, date-stamped from the vendor page |
| 2. Biomarkers in the base panel | What the advertised price includes, not the maximum available |
| 3. Physician access | Bundled, paid add-on, or none |
| 4. Prescription pathway | Whether the program can prescribe, and what that costs separately |
| 5. Retest cadence | How often the panel repeats — the largest hidden cost driver |
| 6. Ongoing reassessment | Whether anyone revisits the protocol after the first read |
| 7. Draw type | At-home kit, partner lab, mobile phlebotomy, or in-clinic |
| 8. Hidden costs | Line items reproduced by walking the actual checkout flow |
| 9. Public litigation | Open lawsuits or major regulatory actions that are public record, with citations |
| 10. Best for | Audience fit, applied with the same wording across every platform |

| Doctor-led programs compared | All six physician-led programs on one rubric, alphabetically, with the real first-year cost |

How We Review
Every price on this site is date-stamped and pulled from the vendor's public pricing page. Every hidden cost is a real out-of-pocket line item reproduced by walking through the actual signup flow to the payment screen. Pricing across all reviewed platforms is revisited at least quarterly, because entry tiers in this category change several times a year.
We do not accept free memberships or products in exchange for coverage. Where we use affiliate links, we say so on the page, and affiliate relationships do not affect scoring or category placement. Where a platform ties for a category, we do not break the tie for a sponsor.
This is editorial content, not medical advice. We compare products; we do not diagnose or treat conditions. Read the methodology for the full criteria, or the about page for what independence means here in practice.
