Bryan Johnson’s Psilocybin Longevity Experiment: Testing Psychedelics for Anti-Aging
Bryan Johnson, the biohacking entrepreneur known for his extreme anti-aging protocols, announced this week that he will test psilocybin as a longevity therapy. His approach combines ancient medicine with cutting edge biomarker tracking to determine whether psychedelics can genuinely slow biological aging.

Recent research suggests psilocybin might extend lifespan at the cellular level. Studies show the compound increased survival in aged mice and enhanced cellular lifespan in human fibroblasts. The active metabolite, psilocin, appears to delay cellular senescence while preserving telomere length.
These findings move beyond established mental health benefits. Researchers observed that treated cells maintained their capacity to divide without showing cancerous changes. The compound also activated antioxidant pathways and DNA damage response systems that typically decline with age.

Measuring Rejuvenation
Johnson plans comprehensive biomarker tracking throughout his experiment. DNA methylation analysis will reveal his biological age and individual organ aging rates. Telomere measurements will assess cellular regeneration capacity. Brain MRIs will capture structural changes and calculate brain age.
The Kernel Flow brain interface adds real time cortical activity monitoring. This technology will track how psilocybin affects neural function during each session. Blood panels will measure markers of cellular senescence, inflammation, and neuronal health.
Beyond Mental Health
A recent preprint demonstrated that psilocybin increased cortical entropy during peak effects. This brain state change predicted structural improvements visible on MRI scans one month later. Participants reported enhanced wellbeing and cognitive flexibility that persisted weeks after a single dose.
The neuroplasticity effects appear particularly striking. Even one high dose session can produce rapid antidepressant effects that last months. Cognitive performance improvements have emerged in preliminary studies, suggesting benefits extend beyond mood regulation.
Johnson’s experiment tests whether these brain changes translate into measurable longevity gains. His rigorous tracking protocol may provide the clearest picture yet of psilocybin’s anti-aging potential.
