‘Young Blood’ Transfusions Sell for $8,000 at This California Startup - Seeker

A California-based startup that provides transfusions of human blood plasma from young people to older people claims that results from its human trial show improvements in biomarkers related to Alzheimer’s, cancer, and heart disease. But the assertion prompted calls for caution from outside experts, who warn that the procedure hasn't been rigorously tested and may give seriously ill patients false hope.
The company, Ambrosia LLC, has provided young plasma to “almost 80” paying customers since August 2016 at a cost of $8,000 per transfusion, according to founder Jesse Karmazin, who spoke by phone from the Recode conference in Los Angeles, where he presented the findings.
