Kate Tolo launches women's health biohacking venture with Bryan Johnson

Kate Tolo, who describes her mission as being the female Bryan Johnson for women, is developing a concierge women's health service with biohacker Bryan Johnson, begun in early 2026. After debilitating cramps at her first period at 13 and later emergency care, a doctor suggested endometriosis, which WHO data estimates affects about 10% of women of reproductive age, but she refused laparoscopic surgery for diagnosis. Her regimen includes extensive health testing.
