Dave Pascoe is one of today’s most recognizable biohackers. The 63-year-old man takes over 170 different dietary supplements daily, experiments with anti-aging technologies like hyperbaric oxygen therapy, and attempts to prove that even “ordinary people” can significantly improve their health. According to him, his current epigenetic age is only 43, and the most flattering epigenetic age was 37.95! He currently ranks among the top 11 of the Longevity World Cup, and has previously outperformed the contest’s founder, Bryan Johnson, who spends $2M a year on anti-aging. At the 6th #TimePieLongevityForum, he shared how he has used biohacking strategies to reverse biological aging and offered practical advice for the general public.

A. Executive Summary
The speaker, Dave (ranked #6 on the Rejuvenation Olympics leaderboard), presents a counter-narrative to the approach popularized by billionaire Bryan Johnson (ranked #7). He argues that superior age-reversal results are achievable not through spending millions, but by mastering five physiological fundamentals: eliminating toxic exposure, consuming regenerative whole foods, constant movement for lymphatic drainage, restorative sleep for glymphatic clearance, and stress mitigation via gratitude.
While Dave admits to an aggressive “biohacking” regimen involving roughly 200 supplements and monthly blood diagnostics, he asserts that gadgets and pills are secondary to these fundamentals. A significant portion of his current protocol involves using multiple Large Language Models (LLMs)—including ChatGPT, Grok, and Gemini—to optimize his supplementation. He uses AI to resolve pharmacokinetic conflicts (e.g., mineral vs. polyphenol absorption) and to cycle compounds to alternate between mTOR activation (growth/muscle) and autophagy (cellular repair). He emphasizes that “exercise in a pill” is chemically possible but physiologically flawed because it fails to mechanically pump the lymphatic system to remove cellular waste.
B. Bullet Summary
Rejuvenation Olympics Ranking: The speaker outperforms billionaire Bryan Johnson on the Rejuvenation Olympics leaderboard using a protocol focused on fundamentals rather than exclusively high-cost experimental therapies.
The “Exercise Pill” Fallacy: Pharmaceutical mimetics for exercise are shortsighted because they cannot replicate the mechanical muscle contraction required to pump the lymphatic system and clear interstitial cellular waste.
Cellular Waste Dynamics: Without manual movement, cells “stew in their own waste,” blocking signaling molecules and reducing nutrient absorption efficiency.
Glymphatic Clearance: The brain lacks a muscular pump; it relies on deep, restorative sleep to contract and force waste through the glymphatic system.
Stress as a Toxin: In 2012, the speaker’s telomere length indicated a biological age of 68 at chronological age 50, attributed to chronic stress (caregiving, job loss, marathon training).
Mindset Reframing: Shifting internal narrative from “I have to” to “I get to” (gratitude) was a primary driver in reversing his biological age markers.
Dietary Protocol: Follows a “feast and famine” approach; time-restricted feeding between 12:30 PM and 5:30 PM.
Macronutrients: Currently high protein (to counteract muscle loss during running season), low carbohydrate, and high monounsaturated fats (olive oil, macadamia, avocado).
Supplement Volume: Consumes ~200 supplements daily, validated by monthly blood panels to monitor liver and kidney function.
Liver Support: Explicitly names Milk Thistle and TUDCA as critical agents for protecting the liver during heavy supplementation.
AI-Driven Optimization: Uses AI to identify antagonistic supplement pairs (e.g., minerals competing with polyphenols) and separates them into different dosing windows.
mTOR vs. Autophagy Cycling: utilizes an AI-designed schedule to induce mTOR (growth) for 5 days (weekdays) and autophagy (cleanup) for 2 days (weekends).
Cold Therapy: Prefers cold showers over immersion tubs due to hygiene and maintenance issues with home setups.
Therapeutic Wishlist: Identifies Plasmapheresis as a top-tier intervention he would use if cost were not a barrier.
D. Claims & Evidence Table
Claim
Evidence Provided
Assessment
Lymphatic flow requires muscle contraction.
Anatomy citation: The lymph system has no heart/pump; relies on movement/massage.
Strong. This is established physiological fact. The lymphatic system relies on the skeletal muscle pump.
Brain waste is cleared primarily during sleep.
Reference to brain contraction and glymphatic system function during deep sleep.
Strong. Supported by neuroscientific consensus (e.g., Iliff et al., 2012).
Stress alone aged telomeres by ~18 years.
Personal telomere test results (Bio-age 68 at Chron-age 50) during a high-stress period.
Speculative. While stress correlates with telomere attrition, commercially available telomere testing has high variability and other factors likely contributed.
Taking 200 supplements is safe.
Personal monthly blood tests showing stable liver/kidney markers.
N=1 / Risky. Polypharmacy carries significant risk of hepatotoxicity and unknown interactions. Safe for him currently, but not generally “safe.”
mTOR/Autophagy cycling improves longevity.
Concept of cycling growth (weekdays) and repair (weekends) via supplements.
Theoretical. The mechanism is sound based on longevity research (rapamycin studies), but the specific 5:2 supplement protocol lacks clinical trials.
Minerals block polyphenol absorption.
AI analysis of chemical interactions (chelation/competition).
Strong. Many minerals (iron, calcium, magnesium) are known to bind with polyphenols or compete for transporters.
E. Actionable Insights
Audit Supplement Timing: Do not take all supplements at once. Use AI to separate minerals from polyphenols/catechins to prevent absorption competition (chelation).
Implement the “Muscle Pump” Rule: If you work a sedentary job, mechanical movement is non-negotiable for waste removal. Chemical mimetics (like GLP-1s) do not replace the lymphatic need for contraction.
Cycle Anabolism and Catabolism: Instead of constantly suppressing mTOR (for longevity) or constantly spiking it (for muscle), cycle your intake. Example: High protein/mTOR inducers on training days, fasting/autophagy inducers on rest days.
Prioritize Liver Support: If taking >10 supplements daily, integrate hepatoprotective agents like TUDCA and Milk Thistle.
Reframe Stressors: Apply the “I get to” vs. “I have to” cognitive reframe to active stressors. The physiological impact of gratitude is a tangible longevity lever.
Hyper-Hydrate the Lymph: Lymphatic fluid requires hydration to move. Combine movement with high water intake.
Optimize Sleep for Glymphatics: Prioritize deep sleep specifically, as this is the window for glymphatic clearance.
H. Technical Deep-Dive
1. The Lymphatic vs. Glymphatic Clearance Systems
The speaker correctly identifies a critical distinction in waste management.
Peripheral Clearance (Lymphatic): The interstitial fluid (ISF) accumulates metabolic waste. Unlike the cardiovascular system, the lymphatic system is a low-pressure, open loop system. Flow depends on extrinsic compression (skeletal muscle pump) and intrinsic rhythmic contraction of lymphangions. Sedentary behavior leads to lymphostasis, resulting in localized toxicity and inflammation.
Central Clearance (Glymphatic): The CNS lacks traditional lymphatic vessels. Instead, cerebrospinal fluid (CSF) enters the brain parenchyma along para-arterial spaces, mixing with ISF and washing solutes (like amyloid-beta) into para-venous spaces. Crucial Note: The interstitial space increases by ~60% during NREM sleep, drastically lowering resistance to flow. This validates the speaker’s claim that sleep deprivation inherently accelerates “brain aging” via waste accumulation.
2. Pharmacokinetic Optimization via AI
The speaker’s use of AI addresses Bioavailability Competition, a common failure point in biohacking.
Chelation: Polyphenols (e.g., EGCG in green tea, quercetin, curcumin) contain phenolic hydroxyl groups that bind with metal cations (Iron, Zinc, Calcium), forming insoluble complexes that are excreted rather than absorbed.
Transporter Competition: Amino acids and certain peptides compete for the same solute carrier (SLC) transporters in the gut lining.
Strategy: Segregating intake into “bio-compatible windows” (e.g., minerals AM, polyphenols PM, or separated by 2+ hours) significantly increases the effective dose (Area Under the Curve) without increasing the oral dose.
3. The mTOR/Autophagy Switch
The speaker’s 5:2 cycling addresses the “Goldilocks” problem of mTOR (Mechanistic Target of Rapamycin).
Chronic mTOR Activation: Leads to accelerated aging, senescence, and cancer risk.
Chronic mTOR Inhibition (Autophagy): Leads to sarcopenia, frailty, and immune suppression.
The Protocol: High protein/leucine intake (mTOR activation) during the week supports muscle synthesis (vital for the skeletal muscle pump mentioned above). Fasting or taking mimetics (e.g., Spermidine, Resveratrol, Rapamycin) on weekends triggers macroautophagy to recycle damaged organelles.
I. Fact-Check Important Claims
Claim:Exercise pills cannot replace movement due to lymphatic mechanics.
Verdict:Accurate. While drugs like SLU-PP-332 or AICAR can mimic metabolic transcription factors (increasing mitochondrial biogenesis), they do not generate the hydrostatic pressure gradients required to return lymph to the venous circulation.
Claim:Supplements like TUDCA regenerate the liver.
Verdict:Supported. Tauroursodeoxycholic acid (TUDCA) is clinically proven to reduce endoplasmic reticulum stress and prevent apoptosis in hepatocytes. It is a standard treatment for cholestatic liver diseases.
Claim:Telomeres of a 68-year-old at age 50.
Verdict:Context Required. While stress accelerates telomere shortening (Epel, PNAS, 2004), commercial telomere tests (usually measuring leukocyte telomere length) have a high margin of error and fluctuate based on immune status and inflammation. This metric should be viewed as a trend indicator rather than an absolute biological age.
You will lost your IgG immune proteins, and might compromise your immune system badly. They restores pretty slow, weeks. And almost all cytokines will come back in 1-2 days. Plasmapheresis is not good intervention at all. Unless you do not have urgent health issue, when you need to clean your plasma right here right now.
And there is second thin and exquisite moment. If you are in some “A” state, and by putting some efforts move to “B” state, then some of your attributes (saying on a language of dynamics systems) won’t come after you. For example, You can quickly loose some huge weight. But your lipids, or any other factors will stay at your old numbers, or moving too slowly to the desired ranges. Then plasmapheresis can kinda “reset” your condition, and reset your “A” attractor. And the new plasma will be filled to the new levels of substances of yours.
But - for this you will need only one intervention, not the series of them. And only already being in your new better “B”-state.
From my unprofessional point of view, serial plasmapheresis of any kind in the name of longevity just a waste of time and money. And putting you at some new risks. The mechanics just “don’t play”.
Do not forget that you have your own excretion system, very good one. If you move slowly, it will clear your perfectly. And especially if you are already “here”, keeping in mind many years of longevity enthusiasm.
I think he’s just lucky. This is the secret. Because " 1. Cycle Anabolism and Catabolism: Instead of constantly suppressing mTOR (for longevity) or constantly spiking it (for muscle), cycle your intake. Example: High protein/mTOR inducers on training days, fasting/autophagy inducers on rest days." - its impossible. If you induce mTOR you will age. If you take Rapa every week, its no time for you to activate mTOR. In my opinion, its just don’t make sense. Tell me if I’m wrong.
3 Experts: The Surprising Truth About What Makes You Age
I. Executive Summary
This roundtable hosted by Ben Greenfield features Gary Brecka (founder of 10X Health System), Dr. Anurag Singh (Chief Medical Officer at Amazentis/Timeline Nutrition), and Dave Pascoe (a 61-year-old biohacker ranked on the Rejuvenation Olympics leaderboard). The conversation addresses systemic aging, spanning actuarial mortality modeling, mitochondrial mitophagy, and personal biohacking stacks.
The primary theses divide into three distinct domains:
Actuarial Physiology & Hypoxia: Brecka asserts that life insurance underwriting algorithms predict individual mortality to the specific month, concluding that “the presence of oxygen is the absence of disease”. He argues that systemic hypoxia drives all oncogenesis and cardiovascular progression, and proposes commercial interventions—specifically Exercise With Oxygen Therapy (EWOT) and Pulsed Electromagnetic Field (PEMF) therapy—to alter red blood cell surface charges, reverse cellular clumping, and restore tissue oxygenation.
Targeted Mitophagy & Immune Rejuvenation: Dr. Anurag Singh details the clinical translational pipeline of Urolithin A (UA, trade name Mitopure). Moving beyond earlier trials documenting enhanced skeletal muscle torque, Singh presents findings from the 2025 Nature Aging “MitoImmune” randomized controlled trial. The trial demonstrated that 1,000 mg/day of UA in middle-aged adults induces mitophagy in peripheral blood mononuclear cells, expands naive CD8+ T-cell and natural killer (NK) cell subsets, boosts fatty acid oxidation capacity, and suppresses chronic inflammaging markers.
Ad-Libitum Epigenetic Pacing: Dave Pascoe presents self-experimentation data demonstrating a DunedinPACE rate of aging of 0.66 years per calendar year, despite an ad-libitum diet exceeding 3,000 kcal/day and avoiding caloric restriction or exogenous testosterone replacement therapy (TRT). His regimen relies on a dense multi-supplement protocol (including DHEA, pregnenolone, and mitochondrial precursors), heavy volume resistance/aerobic work, and stress reduction.
Scientifically, these narratives range from peer-reviewed clinical data to speculative pseudobiology. Dr. Singh’s claims regarding Urolithin A are supported by peer-reviewed human RCTs documenting measurable improvements in mitophagy markers and immune phenotyping, though longitudinal infection resistance and cancer survival endpoints remain unestablished.
Conversely, Brecka’s statements regarding life insurance algorithms predicting mortality “to the month,” along with claims that PEMF therapy “alkalizes” cells by modulating red blood cell zeta potential to drive tissue pH, are factually incorrect and physiologically untenable. Systemic human pH is strictly defended within narrow homeostatic boundaries (7.35–7.45) by the bicarbonate and renal buffering systems, not by electromagnetic induction. Pascoe’s DunedinPACE results reflect real epigenetic pacing, but attributing his outcome to a ~150-pill polypharmacy stack introduces severe uncontrolled variables and potential hepatic/renal risks.
II. Insight Bullets
Gary Brecka claims that life insurance underwriting databases use five years of medical and demographic records to forecast human death to the exact month.
Brecka operates 10X Health System, marketing commercial biohacking modalities including hyperbaric therapy, genetic testing, PEMF, and red light beds.
Brecka claims that tissue hypoxia is the primary etiological catalyst for all human oncogenesis and cardiovascular disease progression.
The Warburg effect—aerobic glycolysis in the presence of adequate oxygen—is mischaracterized by Brecka as an obligate consequence of environmental tissue hypoxia.
Greenfield utilizes a wearable red light device manufactured by Kineon around his neck to irradiate blood passing through the carotid arteries.
Greenfield highlights portable photobiomodulation units from Joovv for travel-based circadian lighting.
Brecka’s “Superhuman Protocol” packages electromagnetic field exposure (PEMF), concentrated hyperoxia (EWOT), and photobiomodulation (PBM) as a commercial longevity stack.
Brecka claims that PEMF mats alkalize bodily tissues by altering cellular polarity, conflating electrochemical zeta potential with systemic hydrogen ion concentration (pH).
Erythrocyte aggregation (rouleaux formation) viewed via unvalidated dark field live blood analysis is promoted as a metric for systemic hypoxia.
Greenfield pairs the Vasper Systems platform—which combines liquid-cooled vascular compression plates with earthing—with supplemental oxygen.
Exercise With Oxygen Therapy (EWOT) utilizing high-volume reservoirs like LiveO2 delivers fraction of inspired oxygen (FiO2) up to 95% during interval sprint bouts.
Dr. Anurag Singh directs research at Timeline Nutrition, the biotechnology spinout developing the proprietary postbiotic Urolithin A (Mitopure).
Earlier phase II clinical trials led by Singh demonstrated that 500–1,000 mg/day of Urolithin A increased hamstring muscle endurance and peak torque in middle-aged adults without concurrent exercise training (Singh et al., 2022).
Immunosenescence is driven partly by progressive post-pubertal thymic involution, which reduces the output of naive, receptor-diverse T lymphocytes.
Dr. Singh collaborates with Dr. Eric Verdin, CEO of the Buck Institute for Research on Aging, to evaluate the effects of postbiotics on human immune aging.
The “MitoImmune” randomized, double-blind, placebo-controlled clinical trial administered 1,000 mg/day of Urolithin A to 50 healthy middle-aged participants over 28 days (Denk et al., 2025).
Results from the MitoImmune trial showed that oral Urolithin A restored naive CD8+ T-cell frequencies and elevated fatty acid oxidation capacity in peripheral lymphocytes (Denk et al., 2025).
Ex vivo functional testing demonstrated that monocytes isolated from subjects supplemented with Urolithin A displayed greater phagocytosis of Escherichia coli (Denk et al., 2025).
Dr. Florian Greten’s preclinical oncology models demonstrated that dietary Urolithin A improved anti-tumor T-cell fitness and enhanced survival in colorectal cancer mouse models (Denk et al., 2022).
Dr. James O’Keefe’s cardiovascular literature highlights the potential risks of chronic excessive endurance exercise, including coronary artery calcification, accelerated vascular stiffening, and atrial fibrillation (O’Keefe et al., 2012).
Dave Pascoe tracks his biological aging through epigenetic methylation algorithms developed by TruDiagnostic.
Pascoe uses high-intensity interval training protocols on the CAROL Bike, an AI-driven cycle ergometer utilizing reduced-exertion high-intensity interval training (REHIT).
Pascoe recorded a DunedinPACE score of 0.66 on the Rejuvenation Olympics leaderboard, indicating an estimated biological aging rate 34% slower than chronological time.
Pascoe maintains total serum testosterone levels between 809 and 1,295 ng/dL at age 61 without exogenous TRT, utilizing adrenal neurosteroid precursors (10 mg DHEA and 50 mg pregnenolone daily) alongside heavy training.
Pascoe’s daily biohacking routine incorporates a polypharmacy stack of approximately 170 to 200 supplement compounds distributed across 70 to 235 capsules daily.
III. Adversarial Claims & Evidence Table
Claim from Video
Speaker’s Evidence
Scientific Reality (Current Data)
Evidence Grade (A–E)
Verdict
Insurance underwriters predict human death “to the exact month”
Actuarial probabilistic mortality tables from Brecka’s insurance career
Factually incorrect. Actuarial modeling establishes cohort-level probability distributions, not deterministic individualized dates of death. No model predicts individual death to the month (MacDonald et al., 2018).
Level E
Unsupported
“Presence of oxygen is the absence of disease”; hypoxia causes all cancer
Broad biochemical claims invoking Otto Warburg’s research
Grossly reductive. The Warburg effect is driven by oncogenic mutations (e.g., KRAS, MYC, loss of p53) that reprogram metabolism to aerobic glycolysis in the presence of oxygen, not purely by ambient tissue hypoxia (Vander Heiden et al., 2009).
Level A
Unsupported
PEMF therapy repolarizes cells and “alkalizes” tissue via charge transfer
Dark-field live blood analysis and assertions of changing “potential hydrogen”
Pseudoscience. Systemic and extracellular fluid pH is strictly regulated (7.35–7.45) by the bicarbonate buffering system, pCO2 ventilation, and renal H+/HCO3- flux. PEMF does not alter systemic or extracellular pH (Boron & Boulpaep, 2016). Dark-field live blood testing is diagnostic pseudoscience.
Level E
Unsupported
EWOT improves tissue oxygenation, muscle recovery, and performance
Anecdotal results in professional athletes performing 10.5-min interval sprints
High-intensity training under hyperoxia (FiO2 0.6–0.95) acutely elevates arterial PaO2 and dissolved plasma oxygen, allowing higher acute power outputs, but trials show mixed translation to ambient performance (Peltonen et al., 2001).
Level B
Plausible (Limited Translation)
Urolithin A induces mitophagy and improves skeletal muscle strength
Amazentis randomized controlled trials in middle-aged and older cohorts
Validated. Double-blind RCT (n=88) demonstrated that 500–1,000 mg/day of UA over 4 months significantly increased hamstring peak torque (+12%) and enhanced plasma acylcarnitines without structured exercise (Singh et al., 2022).
Level B
Strong Support
Urolithin A reverses markers of human immune aging (MitoImmune trial)
Confirmed. 1,000 mg/day UA for 28 days significantly expanded naive-like CD8+ T-cell fractions, enhanced fatty acid oxidation, and improved monocyte phagocytosis of E. coli (Denk et al., 2025). Clinical infection endpoints remain unassessed.
Level B
Strong Support
Urolithin A prevents colorectal cancer mortality via T-cell reprogramming
Preclinical murine research published by Dr. Florian Greten
Validated in animal models. UA activates mitochondrial clearance in T cells, driving memory stem cell formation and tumor suppression in murine models (Denk et al., 2022). Human oncological efficacy is unproven.
Cardiovascular literature citing Dr. James O’Keefe
Substantial observational evidence links extreme multi-decade volume endurance exercise (>5-fold PA guidelines) with elevated coronary artery calcium (CAC), myocardial fibrosis, and atrial fibrillation (O’Keefe et al., 2012).
Level C
Strong Support
DHEA and pregnenolone can elevate total testosterone to 1,295 ng/dL
Pascoe’s self-reported monthly hormone panels and upstream precursor dosing
Misleading. While DHEA (10–50 mg) provides mild downstream substrate in hypogonadal or aging men, meta-analyses show negligible total testosterone elevations in healthy males due to peripheral aromatization (Corona et al., 2013). Serum levels >1,200 ng/dL at age 61 are exceptional outliers and suggest confounding variables.
Level A
Speculative
DunedinPACE rate of 0.66 achieved without caloric restriction
DunedinPACE measures leukocyte DNA methylation flux trained against organ-system decline trajectories (Belsky et al., 2022). Pascoe’s score is authentic within the assay parameters, but attribution to a 200-supplement polypharmacy stack is anecdotal and unproven.
