In this brief video, Bryan Johnson explains his regular blood‑draw protocol that measures a total of 63 biomarkers. He outlines the routine tests he always includes—thyroid function and testosterone—while highlighting two markers he monitors closely: IGF‑1, because he is receiving human growth hormone therapy, and ferritin, as he works to restore his iron stores. Johnson notes that about 20 of the 63 markers are selected for specific therapeutic or lifestyle interventions, whereas the remaining roughly 40 are standard routine markers reviewed regularly.
