Expert Longevity Perspective from NOVOS on Bryan Johnson and Project Blueprint

Tech entrepreneur Bryan Johnson has recently been featured in the press for his “Project Blueprint” approach to longevity and biological age results. In this article, we review his Project Blueprint, compare his results to others with more favorable biological age outcomes, and provide practical advice for how anyone, regardless of financial wealth, can improve their own biological age and pace of aging.

If you read the recent Bloomberg article in which one of NOVOS’ Scientific Advisory Board members, Dr. George Church of Harvard Medical School, was cited about tech centimillionaire Bryan Johnson and his anti-aging efforts, you might be wondering whether it’s possible for the masses to reverse the clock on aging. You might also be wondering if he’s taking the right approach. The software entrepreneur, who founded payment processing company Braintree Payment Solutions, drew widespread attention after undertaking an overhaul of his personal health and wellness routine, dubbed Project Blueprint.

What is Project Blueprint?

Project Blueprint is a rigorous regimen that includes dozens of pills daily, a team of over 30 doctors monitoring Bryan Johnson’s bodily functions, a strict diet of the same daily foods and only 1,977 calories per day, hour-long daily workouts, and a sleep routine that includes wearing blue-light-blocking glasses for two hours before bed. The goal is to reverse the aging process in each and every one of Johnson’s organs in an effort to regain the body of an 18-year-old. It’s also a massive undertaking that cost millions to get up and running and will require an investment of at least $2 million this year alone.

Is longevity only for the rich?

Johnson isn’t the only wealthy person to undertake an extreme longevity regimen. Consider the following examples:

  • Billionaire PayPal founder Peter Thiel has been featured for his desire to live forever and for utilizing transfusions of young people’s blood. 
  • Multiple billionaires have invested in cryonic preservation, as in whole-body or brain freezing, in hopes that future scientists may be able to breathe new life into their bodies.
  • Former Amazon CEO Jeff Bezos made the news in 2022 for investing over a billion dollars into Altos Labs, a biotech company working toward “cellular rejuvenation programming.” 
  • Another biotech company, Nectome, charges $10,000 for “brain preservation” after death; as with cryonic preservation, the idea is to preserve the brain for future research and ultimately create a kind of digital consciousness.
  • Celebrities with hundreds of millions of dollars and endless resources do all they can to slow down (or more commonly, actually just hide) their aging. 

Where does that leave the rest of us who don’t have an in-home medical suite and round-the-clock attention to our bodies and minds? Who has the time, money, and resources to undergo dozens of costly medical procedures every month and a team of professionals monitoring our every move? What about those of us who don’t want to make tremendous sacrifices to our quality of life, like continuous caloric deprivation, monotonous and tasteless meals, dozens of daily pills, and engaging in experimental approaches with prescription drugs and even genetic modification?

At NOVOS, we wanted to take time to draw some comparisons between what Johnson is doing and what we are doing to enable everybody to reverse their aging clocks.

Chris Mirabile, the founder of NOVOS, was motivated to address aging and disease after being cured of a brain tumor as a teen. He has since spent his adult life working to increase his own longevity, with impressive results that exceed those of Bryan Johnson and his Project Blueprint protocols. Along the way, Chris experimented with some approaches that Johnson is currently experimenting with, and has made years of iterations and adjustments. With the launch of NOVOS, a Public Benefit Corporation, and with the help of a team of world-renowned longevity scientists and medical professionals, Chris and his team have created a line of supplements, tests, and actionable guidance that support reversing the clock on aging. And these are available to all — not just multimillionaires. Here’s how NOVOS is helping people live healthier for longer through scientific advances to make available the right formula for increased longevity.

The goal is not immortality, but rather longevity

Is it possible to reverse aging? We at NOVOS can certainly get behind the idea of living a longer and healthier life, and we agree that it is possible to slow down and reverse biological age, as measured by epigenetic clocks and physiological organ function. Indeed, NOVOS is built on that very principle, and our scientific research demonstrates unequivocally that slowing aging is a reality. We have the proof in not only Chris Mirabile but also in the case studies performed with NOVOS community members. We also have countless testimonials submitted by our customers who have added NOVOS’ products to their daily routines. 

What’s different about NOVOS’ approach, as well as Chris Mirabile’s, is that we believe that a long lifespan is not about being immortal and trying to live forever, nor is it about spending millions of dollars on treatments with questionable results. Rather, the goal is to extend the period of healthy function by slowing down the aging process at its fundamental biological causes, increase health span by delaying or avoiding the onset of chronic diseases of aging, and to extend lifespan in the process. This is how we would define “longevity” and is what NOVOS sets out to do. It’s about being younger for longer.

For some, even NOVOS’ research may seem “extreme” at first glance, in the same way that antibiotics were once considered to be on the fringe. Decades later, antibiotics have been shown to extend the average human lifespan by 23 years, and now this scientific innovation is commonplace. Addressing the fundamental causes of aging to extend healthy lifespan is no more extreme; it’s just the 21st century equivalent and one that has measurable results. Furthermore, when you compare NOVOS’ approach to the genuinely extreme methods used by Bryan Johnson, you can begin to see that NOVOS offers a much more balanced, more effective solution to reverse the clock on aging without overly taxing your lifestyle or wallet.

You don’t need to spend millions or go to extremes. You just need the right knowledge.

NOVOS also differs from the Bryan Johnson Blueprint method in that we have demonstrated that the path to longevity does not require exorbitant amounts of money. It simply requires having the right knowledge, as provided on this blog and in NOVOS’ video content, and a desire to improve your lifestyle.

Bryan reduced his biological age by 2.5 years versus his chronological age — from 45 to 42.5, a 5.5% reduction; meanwhile, Chris reduced his biological age by 13.6 years versus his chronological age — from 37.2 to 23.6, a 36.6% reduction.

Consider that many people who pursue so-called anti-aging regimens, especially celebrities, are not improving their lifespans and health spans. They’re actually shortening them or increasing their risks for disease with therapies like HGH and TRT (which Johnson also takes). In contrast, NOVOS provides the best guidance via our team of world-renowned experts whose combined experience informs every ingredient we include in our supplement line and lifestyle advice we provide in our content, such as in our article 60 Top Tips to Live Longer, Doctor-Approved.

Let’s talk about results.

As Chris Mirabile openly shares on his website,, he has reversed his biological age 6.5 times as much as Bryan Johnson, according to scientific epigenetic blood tests independently run by and validated by the same scientific lab as Bryan Johnson’s, without spending millions of dollars on tests or sacrificing his quality of life. In fact, the laboratory that ran the identical tests for both Chris Mirabile and Bryan Johnson commented about Chris’ results, “Quite frankly, we haven’t seen a score this good, but it is accurate.”

Bryan Johnson reduced his biological age by 2.5 years versus his chronological age — from 45 to 42.5, a 5.5% reduction; meanwhile, Chris reduced his biological age by 13.6 years versus his chronological age — from 37.2 to 23.6, a 36.6% reduction.

And according to perhaps the most powerful and accurate of all epigenetic clock tests, the DunedinPACE clock, which measures one’s current rate of aging, the third-party lab reported that Chris Mirabile is aging at 0.69 (31% slower than average), while Bryan Johnson is aging at 0.76 (24% slower than average). Many additional physiological aging measures further corroborate these results.

Everyday people also reversed their biological age with NOVOS.

Furthermore, NOVOS has customers who are sharing their results of their biological age tests, and after taking NOVOS Core and Boost and following our lifestyle advice, they are significantly slowing down their rate of biological aging. One verified customer had this to say: “I tested my biological age with an epigenetic test prior to starting NOVOS Core. I was 1.8 years younger than my chronological age. I started daily NOVOS Core packets, and six months later, I repeated the test. I was 8.4 years younger than my chrono age! I am excited about the results!” (Amy B., MSN, APRN, FNP-C.)

NOVOS recently received results from a case study that administered NOVOS Core and Boost to 11 participants (six female, five male), chronologically aged 39 to 76. They completed the DunedinPACE analysis before taking NOVOS and again after six months. Of those participants, 73% improved their rate of biological aging, with an average percent change of minus 6.1% and as much as minus 14%. Among the small group who did not improve, there was no statistical change, meaning they maintained their pace of aging, which might actually be a good thing. That is, their longevity might have worsened had they not taken NOVOS. Zero participants had an increase in their pace of aging. Note that the p-value for the results, at 0.001, is well beyond the statistical significance benchmark of 0.05. In other words, the results are 50 times less likely to be by random chance than what scientists usually require to consider something as “statistically significant,” or not coincidental.

You don’t need to sacrifice your quality of life. 

While we applaud Bryan Johnson and other multimillionaires’ efforts to increase their lifespan, we also want to reinforce the message that living healthier for longer isn’t reserved just for the wealthy, nor does it require going to extremes in the manner that Bryan Johnson is doing. In fact, you can get comparable and even superior results by following protocols being developed by NOVOS, along with our world-renowned team of longevity biologists and geneticists. As the leading scientific authority for consumers in the space with a founder who personally tests the limits of longevity, NOVOS is proof that anyone can make progress toward a longer, healthier life with just a few simple lifestyle changes and protocols.

“I tested my biological age with an epigenetic test prior to starting NOVOS Core. I was 1.8 years younger than my chronological age. I started daily NOVOS Core packets, and six months later, I repeated the test. I was 8.4 years younger than my chrono age! I am excited about the results!”
-Amy B., MSN, APRN, FNP-C.

Other NOVOS customers who elected to submit their results to Bryan Johnson’s own Rejuvenation Olympics have achieved fantastic results as shared on his leaderboard. For example, NOVOS customer Julie Gibson Clark outranked Bryan by achieving a minus 19.8% biological age to chronological age and a slower pace of aging compared to Bryan’s result of minus 17.4%. When asked, Julie said she achieved these results by simply taking NOVOS Core and Boost, and generally following NOVOS’ lifestyle guidance.

In contrast, Bryan Johnson’s approach has required significant shifts in his lifestyle that are not necessary and may not be available to all. Ashlee Vance, the author of the Bloomberg article, writes: “The handful of doctors I’ve interviewed on Johnson’s team all say he’s breaking ground in the field of longevity and probably extending his life, but even they have questions about whether their conclusions will apply to the rest of us.”

One interventional oncologist, Kristin Dittmar, further notes: “I think what he’s doing is impressive, and he has personally challenged me to be better. What he does is also essentially a full-time job.” With NOVOS, it’s anything but a full-time job; simply take one daily packet, improve your results with NOVOS Core, and follow our science-based lifestyle guidance to enjoy great results for “the rest of us.”

Furthermore, according to the article, because he is not seeing “remarkable results,” as one of his doctors puts it, Johnson is about to take an even more aggressive approach by undergoing far more experimental procedures such as gene therapies that would alter his genome. While he calls dedicating his body to science in this way a “new frontier,” it is once again a questionable undertaking — one that NOVOS does not promote at this time. In fact, here at NOVOS, we do not require you to attempt anything that would edit your genome to improve your biological age. 

Bottom line: There is no point in doing anything that’s not only extreme but also not necessarily beneficial for your lifespan and health span. Instead, your best bet is to start by learning more about the root causes of aging — especially if you’re new to longevity science and perhaps read the Bloomberg article through the lens of someone who wants a simpler, more affordable, more effective approach to extending lifespan and health span. This will help you approach any kind of regimen, whether Project Blueprint or any other, with a dose of skepticism and an eye toward finding the most effective methods. You can then make the best choices to help reverse the clock on aging.

Constructive Feedback on Bryan Johnson’s Blueprint

Here’s a closer look at just a few of the noteworthy facts and stats mentioned in the Bloomberg article, along with our thoughts on the pros and cons of Bryan Johnson’s Blueprint approach.

  • Vegan diet. We at NOVOS acknowledge that Bryan Johnson’s diet is much better than the standard American diet; however, our research also shows that a vegan diet is not ideal for longevity, as evidenced across Blue Zones of supercentenarians, and also necessitates supplementation. Mediterranean diets, which include a moderate amount of fish and lean meats, are consistently shown in research to be the best diets for longevity and even mental health (R,R,R,R,R,R,R). Even better than that is the NOVOS Longevity Diet, which builds upon the Mediterranean diet and further optimizes it. Compared to Bryan’s approach, this allows for a lot more variety (which is beneficial for the microbiome), tasty meals, and the ability to be social with friends (being social is in itself an important dimension of being younger for longer (R)).

  • Diet lacks diversity. Many of the ingredients in his diet are superfoods, including chlorella, garlic, ginger, turmeric, cocoa, extra virgin olive oil, avocado, and nuts. Yet, his standard diet of three meals lacks diversity, which is not ideal for the microbiome. However, for most people, incorporating these ingredients would be an upgrade. Here’s what we recommend:
    • 30+ plant foods per day for ideal microbiome diversity. As the American Gut study has shown, eating the same three meals is not ideal for this.
      • Why microbiome diversity? It results in better health outcomes, reduced frailty, and improved immune systems (R,R,R).

  • Extremely low body fat. Bryan Johnson’s body fat hovers around 5-6%. In one study of men aged 65 and older, very low body fat percentages were linked with an increased risk of death (R). Although we don’t yet know how these mortality findings apply to younger men and women, we would argue that Bryan’s extremely low body fat percentages do not constitute homeostasis and therefore would be nefarious in the short, medium, and long term.

    Specifically, body fat levels and all cause mortality rates have a J-shaped curve, where going too low (likely, below the 6% threshold) is not ideal and can result in health risks ranging from hormonal imbalances, organ damage and decreased bone mineral density (R,R,R,R,R,R,R,R,R). The lower body fat percentage is nonetheless better than being overweight, but we would recommend adding a couple of percentage points to Bryan Johnson’s overall body fat percentage for him to be in the 8% to 10% range. 

    Further, some subcutaneous body fat can actually be a good thing, serving as a barrier against viruses and germs that can penetrate the skin, and producing hormones like adiponectin, which are found at high levels in centenarians.

  • 1,977 calories a day. Bryan Johnson’s calorie intake is likely too low for his activity levels and basal metabolic rate. Although up to a 25% caloric deficit may reduce the risks for certain diseases and may even slow aging, Bryan is going beyond that 25% threshold. Considering his daily 60 minute exercise routine, which includes high intensity interval training (HIIT), and his basal metabolic rate based on his sex, age, body weight and height, we calculate his caloric deficit to be approximately between 31% to 40% or greater, depending on his exercise intensity and if he’s moderately active for the remainder of the day. Our research shows that long-term calorically deprived diets to this extent can lead to poor mood or depression, low libido, fatigue, weaker bones, nutrient deficiencies, and other consequences.

    Going just a little further on calorie restriction (men consuming 1,570 calories, but also significantly lower activity levels than Johnson), as demonstrated in the 1945 Minnesota Starvation Experiment, found that nearly all subjects experienced periods of severe emotional distress and depression, signs of social isolation and withdrawal, decline in concentration and judgment capabilities, reduced body temperature and basal metabolic rate, and even an instance of self mutilation. To say the least, this is not an area we advise people to experiment with. With that said, eating fewer calories than you crave each day is good, and being hypocaloric at a range that’s within the 25% threshold may also be good for longevity — but we don’t advise you to take it any further.

    Unfortunately, despite all of this caloric sacrifice, Bryan Johnson is likely counteracting its potential benefits due to the hormones he takes. Specifically, as well-known longevity researcher, endocrinologist and geriatrician Dr. Nir Barzilai has shared, “animal models whose levels of hormones were maintained at caloric-restricted levels in isolation did not realize extended life spans. So far, the only decrease that’s known to make a difference in longevity is the decrease in growth hormones” (emphasis added).

  • TRT (testosterone replacement therapy), DHEA, & HGH (human growth hormone). Dr. Barzilai has also stated, “Regardless of the hype, I can tell you with certainty that growth hormones do not grow your life span.”

    Bryan Johnson seems to be able to maintain such low caloric levels due to an unhealthy cycle of disrupting his testosterone levels and then making up for it with testosterone patches, HGH and the steroid hormone DHEA. This is an unsustainable method and a simplistic view of biology in that abrogating testosterone and HGH as a result of caloric restriction interferes with other bodily functions, including signaling pathways — to such an extent that testosterone patches and HGH eventually cannot compensate for the lack of production.

    While caloric restriction and fasting can be beneficial in terms of signaling hormonal and biological pathway changes, Bryan Johnson is likely counteracting those benefits by using testosterone patches, HGH and DHEA. And while these patches may initially make him feel young again, TRT is not good for lifespan and healthspan; nor is HGH.

  • 17α-estradiol hormone. In contrast to androgens like TRT and DHEA, Bryan Johnson also includes 17α-estradiol in his stack. While 17α-estradiol, a steroidal estrogen hormone, has been found by the Interventions Testing Program (ITP) to extend lifespan in male mice, the efficacy and long term side effects in male humans – especially when combined with many other hormones (including androgens), prescriptions and supplements – are not known.

  • Additional prescription drugs. In addition to testosterone replacement therapy, Bryan Johnson indicates he is using prescription drugs that include a diabetes drug, metformin (2,000 mg daily); another diabetes drug, acarbose (400 mg daily); and an immunosuppressant drug, rapamycin (13 mg) bi-weekly.

    Each of these drugs is theorized to favorably impact human aging, based on animal studies and hints in human biology and outcomes. However, they are not yet proven and well understood in that context, and the combination of all four of the prescriptions (including TRT), at these high dosages, is uncharted territory, especially for someone with Bryan Johnson’s low body weight, high activity levels and low calorie intake.

    For example, the acarbose dosage indicated for diabetics is 25 mg, up to 100 mg, every 8 hours, based on (high) blood glucose levels. Bryan Johnson’s dosage is 200 mg at a time, 400 mg daily, even with his low blood glucose levels. The metformin dosage is at the higher end of the range assigned to overweight diabetics with very high glucose levels, and the rapamycin dosage is more than 200-300% greater than the dosage typically used for off-label, experimental purposes.

    Beyond the dosages are the overlapping biological pathways that these drugs have with one another, and with Bryan Johnson’s lifestyle (e.g., low calorie diet, intense physical exercise, supplements like spermidine, low body weight and fat, etc.). He is likely taking this too far, and then adding the androgenic hormones testosterone and DHEA to the mix sends simultaneous conflicting signals.

    Ultimately, the dose makes the poison and more is not better. In our professional estimation, this approach is overly simplistic, where every drug that has purported longevity benefits is added to the routine at maximum dosage, without first comprehending the biology and dysergies (negative synergies) between them and one’s individual lifestyle and health situation. We caution against this highly experimental approach.
