Bryan Johnson Questions Longevity Experiment After Gastritis Diagnosis
U.S. tech entrepreneur and bio‑hacker Bryan Johnson, who has spent roughly €8.7 million (about $10 million) on his Project Blueprint anti‑aging program, announced a diagnosis of autoimmune gastritis in July 2026. The chronic, incurable condition attacks the stomach lining and prompted Johnson to post on X, "Been thinking things over and wonder if I’ve taken this whole longevity thing too far," sparking debate about the limits of his regimen.
Johnson also revealed that he has created "Baby Bryan" by reprogramming his own blood cells into induced pluripotent stem cells (iPSCs). Scientists clarified that this process does not constitute a true human clone but is a standard iPSC technique. The cells currently exist only in a petri dish and are intended for future research on organ and tissue regeneration. Johnson’s Blueprint protocol, which includes a strict plant‑based diet, daily exercise, extensive biomarker testing, supplement regimens and experimental therapies such as plasma transfusions from his son, is reported to cost about $2 million per year.
