Methodology
How we separate clinical efficacy from longevity marketing.
The Standard of Evidence
The longevity industry is plagued by a reliance on preclinical models (specifically murine/mouse data) being extrapolated to humans. Our methodology strictly prioritizes human clinical trials.
- Tier I: Human RCTs showing lifespan/healthspan extension (Rare).
- Tier II: Strong human biomarker data from Phase II/III trials.
- Tier III: Observational human data or strong primate data.
