An independent field guide to extending healthspan

An atlas of the
measurable body.

19 territories. 176 devices catalogued. 21 FDA filings decoded. Plotted by calibrated instrument, decoded line-by-line, and priced on a real three-year horizon — a working chart of every tool currently sold to extend the human lifespan.

Fig. VI · The legend

How the atlas is drawn.

§ 1 Bench first

Every device passes calibrated instruments before it gets a score. No exceptions.

§ 2 Filings read

PMA · 510(k) · registered · wellness · DSHEA. We link the openFDA record.

§ 3 Three-year horizon

Cost = hardware + subscription + consumables + energy, over 36 months.

§ 4 No paid placement

Affiliate links exist; rank order doesn’t move. Ever.

§ 5 Conflicts disclosed

Any unit a manufacturer supplied is flagged on the bench page.

§ 6 Errata published

A correction log lives in the back matter, dated and signed.
