Bryan Johnson Livestreams High-Dose Psilocybin Session as Tech Luminaries Tune In

The public self‑experiment frames psilocybin as a longevity probe with on‑camera biometrics.

Overview

  • Johnson consumed roughly 5.4 grams of mushrooms for a six‑hour broadcast, citing 28 mg of psilocybin, with pre‑ and post‑trip measurements and a Kernel brain‑monitoring helmet.
  • Grimes performed a DJ set during the stream, which also featured appearances by Marc Benioff, Naval Ravikant, and David Friedberg.
  • The livestream on X drew over a million views in live and replay traffic, according to TechCrunch.
  • Psilocybin remains illegal federally and is not legal in California, and reporters could not confirm the session’s location or the source of the mushrooms.
  • Johnson linked the trial to early Baylor and Emory research on lifespan in cells and animals, though any human longevity benefit is unproven and independently unverified.
