Bryan Johnson recaps a Baseten longevity event
PUBLIC REACTION: Johnson says more than 3,500 people applied for 150 Baseten event places and attendees used bioage tests; he reports no individual results, protocol change, or clinical outcome.
Summary Did this longevity event show that bioage tests improve health? Show / hide ↓
A public post described an event where more than 3,500 people applied for 150 places. Attendees discussed health, performance, and bioage tests, which estimate biological age from body measurements. The report did not say which tests were used, how many people completed them, or what results they had. It also reported no treatment, comparison group, follow-up, or health outcomes.
What this means for you: This event recap does not show that bioage tests improve health or extend life. You can ignore it when deciding whether to buy a test or treatment.
weak evidenceOn 29 August 2026, Bryan Johnson posted a short recap of a longevity event with Baseten. He says more than 3,500 people applied for 150 places and that attendees were interested in bioage tests. He also lists discussion themes: doing ambitious work, using health to support performance, changing social norms around valuing life, and making health trade-offs with data. The post names Sarah Guo as a good fit for the event and thanks several organizers. It does not identify the bioage test, report participant-level results, state how many tests were completed, or provide a prespecified analysis. It also supplies no intervention, comparator, follow-up period, adverse-event report, or clinical endpoint. The application count is an event statistic, not a health result. This item records a public reaction and event recap rather than a self-experiment. It offers no basis for judging whether any bioage measure is valid, responsive to an intervention, or related to lifespan. No ingredient or biomarker evidence-grade change follows. The only durable update is that Johnson is using public events and bioage testing as part of his communication strategy.
Amazing longevity event with @baseten
No relevant critic article, PubMed paper, or preprint dated 27 August–2 September 2026 was found. The post contains no human trial result and does not justify an evidence-grade upgrade.
