Sold Braintree/Venmo for $800M, then turned himself into a longevity experiment. Bryan Johnson spends $2M+ per year on anti-aging protocols tracked by a team of 30+ doctors through Project Blueprint. Every peptide trial gets biomarker data before, during, and after. He halted tirzepatide after 3 weeks when his resting heart rate climbed 3bpm and HRV dropped 7 points. That kind of discontinuation data, with exact numbers attached, is rare. Four protocols on Peptide Schedule, including two he stopped.

Bryan Johnson
Bryan Johnson treats his body like a dataset. After selling Braintree/Venmo for $800M, he launched Project Blueprint and now spends $2M+ per year on longevity protocols tracked by 30+ doctors. Every intervention gets biomarker data before, during, and after. His peptide approach follows the same logic: "Peptides are effective when used precisely." He also notes that research is limited for many peptides, so his advice is to do your research and measure.
The discontinuation data is what stands out. Johnson halted tirzepatide after just 3 weeks when his resting heart rate climbed 3bpm, HRV dropped 7 points, and sleep quality fell 10%. He published those exact numbers. He also reported that cerebrolysin was his "best subjective neuro-enhancer" but produced no measurable biomarker improvement. That kind of honest negative reporting is rare.
Four protocols are tracked on this page (2 active, 2 discontinued). Dosing sourced from tweets with specific post IDs. Confidence tier is 2 for all; tweet-sourced data carries less weight than published articles or clinical studies.
