Bryan Johnson discloses autoimmune gastritis and asserts creation of newborn clone

American entrepreneur and anti‑aging advocate Bryan Johnson announced that he has been diagnosed with autoimmune gastritis, reporting elevated anti‑parietal cell antibody levels and early gastric atrophy. He has spent years monitoring his health through intensive testing as part of his Blueprint longevity program.

In a separate announcement, Johnson claimed to have created a "newborn clone" of himself, describing it as a potential source for organ growth, therapy testing, and regenerative treatments. Scientists and physicians have responded with skepticism, stating that current medical science does not support the feasibility of a viable human clone for the purposes Johnson describes. The claims have sparked debate over the realistic prospects of human cloning and its role in anti‑aging research.

Both disclosures have drawn public attention to Johnson’s experimental health regimen and the broader conversation about the limits of biotechnology in longevity efforts.
