Peter Diamandis is a physician and engineer who has spent thirty years building institutions around big bets: the XPRIZE, Singularity University, Human Longevity Inc, and Fountain Life, the diagnostics company whose members get full-body MRIs, coronary scans and hundreds of blood markers a year. His own protocol, published in his Longevity Guidebook and updated on his newsletter for 2026, is one of the most elaborate on the internet: more than sixty capsules a day, a gram of NMN, peptides, red light, PEMF mats, exosome infusions, and a diagnostic calendar that would exhaust most hospitals. It is also organized around a slogan worth taking seriously: do not die from something stupid. This review separates the stack from the slogan, grades each part by the human evidence, adds up the cost, and ends with the parts worth copying.
Diamandis's protocol in 60 seconds. As he has described it and as the sources listed at the end agree: a supplement stack of sixty-plus capsules built around NMN at about 1 g a day, creatine, CoQ10, alpha-lipoic acid, quercetin, selenium, lion's mane, vitamin D3 with K2, magnesium and omega-3; peptides and hormone optimization under physicians; red light, PEMF and periodic exosome infusions; and an annual diagnostic sweep of full-body MRI, coronary CT, blood work in the hundreds of markers, DEXA and genome sequencing, much of it through his own company. In 2026 he ranks mindset above all of it. Our verdict: the diagnostic idea is the best thing on his list, and its cheap, proven pieces (a standard blood panel, a coronary calcium score, screening on schedule, a DEXA) cost a few hundred dollars; the sixty-capsule stack contains four or five items with strong evidence and dozens without; the peptides and infusions are experiments with no controlled trials, sold at prices that would fund the proven parts for a decade.
The short answer: copy the calendar, not the cabinet. Screen for the things that actually kill people, take the handful of supplements with trials behind them, and treat everything else in his protocol as what it is: a wealthy, informed man's self-experiment.
Who Is Peter Diamandis, and Why Does His Protocol Matter?
Diamandis holds an MD from Harvard and degrees in engineering from MIT, and he has been the most visible optimist in longevity for two decades, arguing that the next ten years of biotech will add decades to life. Unlike most people on our biohacker list, he is also a seller: Fountain Life offers memberships with the very scans and tests his protocol prescribes, at five-figure annual prices. That does not make the scans useless. It does mean his enthusiasm for them is not disinterested, and the evidence has to be read on its own.
His protocol also illustrates a pattern we keep finding in these reviews, from Bryan Johnson's Blueprint to Joe Rogan's stack: the parts with the strongest evidence are the cheapest, and the price sits in the parts that might work. The difference is the diagnostics, which is where Diamandis is genuinely ahead of the others and where the review starts.
The Best Idea: Do Not Die From Something Stupid
Roughly a third of deaths in middle age come from two things that are visible years in advance: heart disease and cancers that screening can catch. Diamandis's rule is to find them early, and the proven tools for that are ordinary. A coronary artery calcium score, a single low-dose CT that costs $100 to $200, predicted heart attacks and strokes better than any blood test in the MESA study of nearly 7,000 adults, and a score of zero is one of the most reassuring numbers in medicine. Colonoscopy or a stool DNA test on schedule prevents most colon cancer deaths. A DEXA scan measures bone density and body composition for under $150. A standard blood panel with lipids, glucose, HbA1c, liver, kidney and thyroid markers costs less than a month of NMN. Those four things are the part of his protocol every adult should copy.
The full-body MRI is a different case. It finds things, and some of them matter, but no randomized trial has shown that scanning healthy people saves lives, and the well-documented cost is a stream of incidental findings that lead to biopsies, follow-up scans and anxiety for growths that would never have caused harm. Genome sequencing and hundreds of extra blood markers have the same shape: interesting, occasionally decisive, mostly noise. If the money is there, they are a defensible luxury. They are not the core.
What Peter Diamandis Takes: The Stack, With the Human Evidence
The grades below are Reverse Age Lab's reading of the human research for the purpose he gives each item. Strong means repeated randomized trials in people show the effect. Moderate means the effect is real but conditional. Early means small or short human studies with mixed results. Weak means no convincing human trials for the claim.
Item | What it is | Why he says he takes it | Human evidence |
|---|---|---|---|
Creatine monohydrate | The most studied sports supplement | Muscle and strength past sixty, brain | Strong for strength and lean mass; early but promising for memory |
Vitamin D3 with K2 | The sunshine vitamin plus a cofactor | Bone, immunity | Moderate: corrects a low level; large trials show no extra benefit for people already replete |
Magnesium | A mineral most diets run short of | Sleep, muscle, heart | Moderate for sleep and for people who are low |
Omega-3 | EPA and DHA | Heart, brain | Moderate at 1 to 2 g a day; higher doses raise atrial fibrillation risk |
NMN, about 1 g a day | A precursor the body turns into NAD | Cellular energy and repair | Early: raises NAD in blood; small trials show modest, mixed functional gains; 1 g is above most trial doses |
CoQ10 | A mitochondrial cofactor | Energy, heart | Moderate for heart failure and statin muscle pain; weak for aging in healthy adults |
Alpha-lipoic acid | An antioxidant | Oxidative damage, blood sugar | Moderate for diabetic nerve pain; weak for anything in healthy adults |
Quercetin (and fisetin, as a senolytic) | Plant flavonoids | Clearing senescent cells | Weak in humans: the senolytic trials are small pilots in specific diseases, with no outcome data in healthy people |
Selenium | A trace mineral | Antioxidant defense | Weak, and a caution: a 35,000-man trial found no cancer benefit and a higher rate of diabetes with selenium |
Lion's mane | A mushroom extract | Cognition | Early: one small trial in older adults with mild impairment; little in healthy adults |
Metformin (prescription) | A diabetes drug | Aging, after the TAME hypothesis | Weak for healthy adults: the anti-aging trial has not run; metformin blunts the fitness gains from exercise in a randomized trial |
Rapamycin (prescription, intermittent) | An mTOR inhibitor | Aging, after the mouse studies | Early: strong in mice; the first human trials are small, with modest signals and side effects to manage |
Peptides (various) | Injectable signalling fragments | Repair, recovery, growth hormone | Weak: most have no controlled human trials, and many are sold outside regulation |
Exosome infusions | Cell-derived vesicles given intravenously | Regeneration | Weak: no controlled trials; regulators have warned about unapproved products |
Red light and PEMF | Light and magnetic field devices | Mitochondria, recovery | Early: small trials for specific uses (wound healing, some pain); nothing for aging |
He also lists a multivitamin, probiotics, fiber, and a rotating set of items that change with each update. None of those change the picture. Hormone optimization, which he pursues with physicians, is medicine rather than supplementation and is not graded here.
What the Evidence Supports
Creatine. The International Society of Sports Nutrition's position stand summarizes decades of randomized trials: 3 to 5 g a day increases strength and lean mass in people who train and is safe in healthy adults. A 2023 meta-analysis found a small memory benefit, larger in older adults. For a man in his sixties fighting muscle loss, which Diamandis says is his priority, it is the single best-supported item in the cabinet.
Vitamin D, magnesium and omega-3, at sensible doses. The same story as every review on this site. Vitamin D corrects a low level and does nothing extra for people who are replete, per the 25,000-person VITAL trial. Magnesium helps sleep in people who are short of it, per randomized trials in older adults. Omega-3 at 1 to 2 g lowers triglycerides and sits below the dose linked to atrial fibrillation in a 2021 meta-analysis. Cheap, boring, and worth taking after a blood test.
CoQ10, in the right person. The Q-SYMBIO trial found CoQ10 reduced major cardiovascular events and deaths in people with heart failure, and smaller trials support it for the muscle aches some people get on statins. Those are real uses. In a healthy adult it is a plausible antioxidant with no outcome data.
The screening calendar. Covered above, and the strongest thing in the whole protocol.
What Is Not Worth Copying, or Needs a Doctor
Sixty capsules. The breadth is the problem, not any one item. Each extra capsule adds a chance of a duplicate ingredient, a dose over a safe upper limit, or an interaction with a medication, and the more products a stack has the less anyone knows what each one is doing. Our stack checker exists for exactly this reason. A protocol with sixty items cannot be evaluated; it can only be believed.
NMN at a gram a day. Human trials of NMN used 250 to 1,250 mg and found reliable rises in NAD with modest, inconsistent functional effects; the best of them, in prediabetic women, improved muscle insulin sensitivity and nothing else measured. A gram a day costs $100 to $150 a month for an outcome nobody has shown. Our full reading is in NAD anti-aging supplements: benefits, evidence, and how to choose.
Selenium. The SELECT trial gave 200 micrograms of selenium a day to more than 35,000 men for years and found no reduction in prostate cancer and a higher rate of diabetes in the selenium group. Unless a test shows a deficiency, this is a supplement with a known downside and no known upside.
Metformin without diabetes. The idea comes from observational data and a proposed trial, TAME, that has not been run. Meanwhile a randomized trial in older adults found metformin blunted the improvements in fitness and muscle from exercise training. For someone whose stated priority is muscle in his sixties, that is the wrong trade.
Rapamycin, peptides and exosomes. Rapamycin is the most interesting prescription in longevity, with striking results in mice and the first small human trials now reporting modest signals alongside side effects that need monitoring; it is a physician's experiment, not a supplement. Peptides are mostly unstudied in humans and often sold outside regulation. Exosome infusions have no controlled trials at all and have drawn regulator warnings. Each of these costs more per month than the entire evidence-backed core costs per year.
What Peter Diamandis's Protocol Costs, and What the Same Evidence Costs
Retail and published prices in the United States as of September 2026, rounded.
Item | Roughly | Evidence |
|---|---|---|
Sixty-plus capsules a day | $300 to $600 a month | A handful strong, most weak |
NMN at 1 g a day | $100 to $150 a month | Early |
Peptides | $200 to $500 a month or more | Weak |
Exosome infusions | Thousands per session | Weak |
Red light panel and PEMF mat | $1,000 to $5,000 once | Early |
Full diagnostic membership (full-body MRI, coronary CT, hundreds of markers, genome) | Five figures a year | Mixed: some strong pieces, much noise |
Coronary calcium score | $100 to $200, every few years | Strong |
Standard blood panel | $50 to $200 | Strong |
DEXA scan | $100 to $150 | Useful |
Colon screening on schedule | Usually covered | Strong |
Creatine, vitamin D3 with K2, magnesium, omega-3 | $40 to $70 a month | Strong to moderate |
The proven part of his protocol, the four screening tools plus the four supplements with trials behind them, costs a few hundred dollars a year plus about $50 a month. The unproven part costs more per month than that does per decade.
The Takeaway: Copy the Calendar, Not the Cabinet
Diamandis is right about the thing most longevity influencers ignore: the biggest gains come from not dying of something a scan or a blood test would have caught. Copy that. Get the calcium score, the blood panel, the DEXA and the screening on schedule, and act on what they show. Take creatine, and vitamin D, magnesium and omega-3 if your numbers say so. Then stop. The sixty capsules, the gram of NMN, the peptides and the infusions are a wealthy man's experiments, run with physicians and without controls, and he is candid that they are bets. His 2026 addition, that mindset outranks all of it, may be the most evidence-based line in the book.
Build Your Own Personalized Protocol
The trouble with a sixty-item stack is not that it is ambitious. It is that nobody, including its owner, can see what is duplicated, what is over a safe limit, and what is interacting with what. Reverse Age Lab is built to make that visible. Rala, our patented AI, reads the human studies and real reviews behind supplements, diet and exercise, then turns them into one personalized daily protocol built around your body, your goals and your blood work, organized so the pieces work together and nothing is doubled up. It checks what you already take for interactions, redundancies and safe upper limits, and it tells you which of a celebrity protocol's items belong in yours. Build your protocol free at reverseagelab.net/protocol, or start by running what you take through the supplement stack checker.
Frequently Asked Questions
What supplements does Peter Diamandis take?
By his own published protocol and the roundups that track it, a stack of more than sixty capsules a day built around NMN at about 1 g, creatine, CoQ10, alpha-lipoic acid, quercetin, selenium, lion's mane, vitamin D3 with K2, magnesium and omega-3, plus a multivitamin, probiotics and a rotating set of others. He also uses peptides and hormone optimization under physicians, red light and PEMF devices, and periodic exosome infusions.
Is NMN at 1 g a day worth it?
Not on current evidence. Human trials used 250 to 1,250 mg and reliably raised NAD in blood, but functional benefits were modest and inconsistent, with the best trial showing improved muscle insulin sensitivity in prediabetic women and nothing else. A gram a day costs $100 to $150 a month for an outcome nobody has demonstrated.
Should I get a full-body MRI like Peter Diamandis?
No randomized trial has shown that scanning healthy people saves lives, and the known cost is a stream of incidental findings that lead to follow-up scans, biopsies and anxiety for growths that would never have mattered. The proven pieces of his diagnostic approach are cheaper: a coronary calcium score, a standard blood panel, a DEXA scan and colon screening on schedule.
Is a coronary calcium score worth getting?
Yes, for most adults over about forty. In the MESA study of nearly 7,000 people it predicted heart attacks and strokes better than any blood marker, and a score of zero carries a very low ten-year risk. It costs $100 to $200 and takes minutes.
Does metformin slow aging?
The claim rests on observational data and a proposed trial, TAME, that has not been run. In a randomized trial in older adults, metformin reduced the fitness and muscle gains from exercise training. Outside diabetes, the trade-off is unfavorable for anyone whose goal is staying strong.
Which parts of Peter Diamandis's protocol are worth copying?
The screening calendar's proven pieces (calcium score, blood panel, DEXA, colon screening on schedule), creatine at 3 to 5 g a day, and vitamin D, magnesium and omega-3 if your blood work says you need them. That comes to a few hundred dollars a year plus about $50 a month. The sixty-capsule stack, the peptides and the infusions are experiments.
