Bryan Johnson Says He May Have 'Taken This Whole Longevity Thing Too Far'

His medical team will monitor biomarkers and pursue experimental immune‑targeting or engineered cell therapies to try to treat his autoimmune gastritis.

Overview

  • Johnson posted on X on Thursday that he is reconsidering his years‑long, high‑cost longevity program and that he may have gone too far in his experiments.
  • Earlier this month his doctors diagnosed autoimmune gastritis after blood tests showed elevated anti‑parietal‑cell antibodies and a stomach biopsy revealed weakening of the stomach lining.
  • Johnson and his team say they will perform routine monitoring of iron and other biomarkers and may try experimental approaches such as targeting immune proteins, rebuilding regulatory T cells, or engineered cell therapy.
  • A recent claim by Johnson that he produced an embryonic‑like newborn 'clone' remains unverified; independent experts say the descriptions resemble lab reprogramming to induced pluripotent stem cells and note no released data or outside confirmation.
  • The episode highlights the human and ethical costs of Johnson’s Blueprint work — he has spent roughly $10 million on extreme regimens and practices (including reported plasma transfusions from his son) that have drawn scientific skepticism and public concern.
