Despite a Food and Drug Administration warning that draining blood from young folk and infusing it into older people might be harmful, startup Ambrosia says it has resumed doing just that.

The exsanguination enterprise earlier this year stopped selling young blood by the liter to old people and filling them up with it, immediately after the FDA issued an advisory that blood-plasma transfusions offered in the U.S. “should not be assumed to be safe or effective” and that consumers should be strongly discouraged from “pursuing this therapy outside of clinical trials under appropriate institutional review board and regulatory oversight.”
