Bryan Johnson, known for spending $2M annually to reverse his body’s aging process, stopped taking a drug that had been tested on mice after experiencing severe side effects.
The businessman had discussed its “longevity benefits” in his Netflix documentary, Don’t Die: The Man Who Wants To Live Forever.
Johnson consumed 13 milligrams of the immunosuppressant rapamycin every two weeks, which is used by transplant patients to prevent organ rejection.
