Bryan Johnson's Blueprint routine, element by element, against the human evidence: what is well supported, what is unproven, and what is self-reported.
Researched from published studies and manufacturer specifications, checked .
We have not tested products ourselves. How we research
The parts of Johnson's routine with strong human evidence are ordinary: regular exercise, good fitness, sleep, moderate calorie restriction. The distinctive parts (the noon cutoff, the large supplement stack, plasma exchange, headline biological-age results) are unproven or self-reported. No independent trial shows his combination extends life.

Pros
Cons
The short answer: Bryan Johnson’s Blueprint routine is a mix of well-supported habits (exercise, sleep, fitness, moderate calorie restriction) and unproven extras (a large supplement stack, medical procedures). No independent trial shows that the combination extends human life, and the biological-age results he quotes are self-reported by a founder who sells related products. Talk to your doctor before copying any part of it.
His own protocol page, read 29 Sept 2026, describes a last meal at noon, an 8:30 pm bedtime, about 2,250 calories a day (which he describes as 10% calorie restriction), and roughly six hours of exercise a week (three strength sessions and three cardio sessions). It reports a skin age of 39 at age 48, a 2.6% telomere length increase and hsCRP below detectable levels. The daily schedule is laid out in the Blueprint protocol breakdown.
Third-party reports relayed by Wikipedia, which we did not check at source: he moved to anti-aging experimentation in 2021, Bloomberg reported a cost around $2 million a year in 2023, and he has since cut daily supplements from 111 to 30 (by March 2026). He has said he will not repeat the 2023 plasma transfusions; the FDA has said such transfusions have no proven benefit and may be harmful.
| Element | Best human evidence | How strong is it for what he claims? |
|---|---|---|
| Daily exercise, high fitness | A cohort of 122,007 patients: lowest fitness carried five times the mortality of elite fitness (HR 5.04). Observational. | Strong association, and among the best-supported habits for longevity. Association is not proof that raising fitness causes the difference. |
| Calorie restriction (about 10%) | CALERIE, 220 adults on 25% restriction for 2 years: slowed DunedinPACE, no significant change in PhenoAge or GrimAge, small effect sizes, post hoc analysis. | Emerging. His level (10%) is lower than the trial’s (25%). |
| Noon eating cutoff (time-restricted eating) | An RCT in 139 people with obesity: time restriction did not beat ordinary calorie restriction for weight or metabolic markers. | Unproven as a longevity tool; any benefit in trials tracks calories eaten. |
| Large supplement stack | See the graded supplement ladder: most compounds have small or mixed human trials. | Weak to Emerging for most items, and untested as a combination. |
| Plasma exchange | No trial supports benefit in healthy people; he says he will not repeat it, and the FDA has warned against it. | Unsupported. |
| Biological-age results | Self-reported on his own channels. No independent verification found. | Not evidence of effect (see below). |
DunedinPACE is the most rigorously built of the epigenetic measures in circulation. It was developed from the long-running Dunedin birth cohort and, in the eLife paper, showed high test-retest reliability and an association with morbidity, disability and mortality. It reports a pace of aging relative to the study population, with 1.0 as the average pace. That is a population-level finding. It does not establish that one person changing their score changes their lifespan, and different epigenetic clocks often disagree on one sample. We could not find a DunedinPACE value on Johnson’s protocol page on 29 Sept 2026, so any specific figure you see quoted should be treated as self-reported. See the epigenetic age testing guide for what each test measures.
The habits with the strongest evidence are the unglamorous ones: regular exercise that builds cardiorespiratory fitness, sleep consistency, and not overeating. These cost nothing. If you want the stack, use the cost per study dose table to see which compounds have a human trial behind a specific dose, and take your questions to a doctor.
Researched from Johnson’s own protocol page (29 Sept 2026), PubMed records for the studies cited, and Wikipedia for dated third-party reports we did not verify at source. We did not test any product or procedure. This is not medical advice; do not copy a medical procedure or a large supplement stack without a doctor.
In parts. Exercise and cardiorespiratory fitness have large observational links to lower mortality, and calorie restriction slowed a DunedinPACE measure in a randomised trial. The full combination, including the noon eating cutoff and the large supplement stack, has not been tested in a trial, and his headline biological-age results are self-reported.
Nobody knows. It is an experiment on one person, with no control group, run by a company that sells related products. Any single result could reflect his genetics, his starting point or the measurement itself.
