‘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.
