Claim · 2026 · Blueprint (Project Blueprint)
As of Blueprint's January 2026 update, Johnson reports an epigenetic 'speed of aging' score of 0.48, telomere length equivalent to a 10-to-15-year-old, and a skin-age reduction from 64 to 36.
The most current iteration of the case’s central claim, self-reported on Blueprint’s own site and not benchmarked against an independent cohort or a hard endpoint. The same peer-reviewed limitation applies as to the 2021 claim: epigenetic and telomere-based scores are population-validated research tools whose translation into individual predictive claims of this kind is not established (Apsley et al. 2025).
