The Longevity Effects Of Psilocybin

Bryan Johnson investigates the potential of psilocybin as a longevity intervention by subjecting himself to two high-dose, medically supervised sessions while tracking over 249 biomarkers. This experiment reveals that psilocybin induces a structural reset in neural patterns, shifting the brain from rigid, age-associated states toward increased entropy and flexibility. Data indicates significant physiological improvements, including a 6.8% reduction in HbA1c, effectively placing glucose control in the top 0.2% of the population, alongside the suppression of low-grade inflammation and a sustained reduction in stress hormones like cortisol. By applying rigorous, data-driven methodology to this compound, the project demonstrates that psilocybin may influence fundamental biological systems—metabolism, hormones, and the microbiome—that drive aging. These findings suggest that psychedelics, when quantified and controlled, offer potential therapeutic value for both biological optimization and long-term health.
