In this brief monologue, Bryan Johnson explains that he is fasted and prepared for a blood draw that will measure 63 biomarkers. He describes using multiple types of collection tubes, with some samples processed in-house by a doctor partner and others shipped to specialized external labs. He notes that this draw will require roughly 15 vials, a significant reduction from the initial Blueprint draw, which involved about 50 vials.
