Tech entrepreneur Bryan Johnson claims to have slowed his father’s rate of aging by 25 years through transfusions of his own “super blood.” In a post on X, Johnson stated that his “super blood” reduced his father’s age by a quarter of a century. Johnson, known for his controversial anti-aging treatments, revealed that his father received one liter of his plasma, which resulted in his aging at the rate of a 46-year-old instead of a 71-year-old. However, Johnson emphasized that his findings were based on one biomarker, without specifying which one. Medical experts caution that biomarkers alone are not a reliable measure of aging.
Johnson also acknowledged that it is difficult to determine if the plasma injection directly caused the change in his father’s aging rate or if other factors were involved. Johnson himself received plasma from his 17-year-old son but did not notice any personal benefits from the procedure. As a self-proclaimed “professional rejuvenation athlete,” Johnson has tried various interventions on himself, including diet, exercise, fat injections, and laser treatments, to slow down aging.
While some US clinics offer plasma injections from young donors as an anti-aging treatment, the FDA has stated that there is no compelling clinical evidence supporting its efficacy. Even in cases like wound healing, where the use of a person’s own plasma may be beneficial, there is no solid evidence that it can reduce aging, according to a post from John Hopkins University.
