After announcing an autoimmune gastritis diagnosis on July 5 2026, Johnson used his X post on July 30 to question whether his intensive Blueprint regimen had been taken too far. He reiterated the components of his program—plant‑based diet, exhaustive biomarker monitoring, daily supplements, experimental plasma transfusions from his teenage son—and noted the creation of an iPSC line dubbed “Baby Bryan,” which resides only in a petri dish for future organ‑regeneration research. The cost of Project Blueprint has reached roughly €8.7 million (≈$10 million) overall, about $2 million per year.

In early August, Johnson again voiced caution, saying the autoimmune diagnosis prompted him to reassess the safety limits of his anti‑aging pursuits. He emphasized that the “Baby Bryan” cells are being used to generate organoids for disease modeling and drug testing, and experts reminded that producing fully functional transplantable organs remains far from clinical reality. His continued self‑scrutiny has kept the debate alive over the ethical and medical boundaries of extreme bio‑hacking and longevity research.
