The NAST Protocol

Brut is champagne with nothing added: nine levers, an hour a day, and the argument that adherence is the binding constraint. NAST is the other end of the same axis — everything defensible, running simultaneously, cost accepted rather than minimised. It is not a better version of Brut. It is a different bet: that time, money and attention are available, and the real limit is how many levers you can stack before they start interfering with each other. For most people that bet is wrong, and this page says so instead of selling the maximum as universally superior.

What you are actually betting

Primary literature

Brut and NAST are not a ladder

The natural assumption is that Brut is the beginner version and NAST is what you graduate to. That is not the relationship. They answer different questions about what is scarce.

Time~1 hour/day~4 hours/day

Levers9~35
Failure modeLeaves ceiling unclaimedCollapses entirely on a bad month
Right forAlmost everyone, almost alwaysA specific season with slack in it

The maths that should decide it: a maximal protocol run at 60% adherence loses to a minimal one run at 95%, because nearly everything here is dose-over-time rather than dose-per-session. NAST only wins if you will genuinely run it at 90%+. Most people running NAST are running Brut badly and paying four times as much for the privilege.

The age gate, again

A large fraction of what makes a protocol maximal is pharmacological, and essentially all of that is inappropriate before the mid-twenties — mTOR inhibition, GLP-1 agonists, growth-hormone-axis work, hormone modulation, aggressive caloric restriction. Under ~25 the maximal protocol and the free protocol are much closer together than the supplement industry would like, because the exotic tier is either useless or harmful in a body still finishing development. NAST at 17 means the behavioural and measurement columns run flawlessly, and nothing else.

The supplement column

  • Tier 1, also in Brut: creatine 5 g · EPA/DHA 1–2 g · vitamin D3 titrated to a measured 30–50 ng/mL · protein to 1.6–2.2 g/kg.
  • Added in NAST, mechanism real and outcome data thinner: vitamin K2 (MK-7) 100–200 mcg with the D3 · magnesium glycinate 200–350 mg elemental · prebiotic fibre (inulin, GOS, arabinogalactan) · urolithin A 500–1,000 mg · CoQ10 100–200 mg · glycine + NAC.
  • Deliberately still excluded, even at maximum: NAD+ precursors (bioavailability confirmed, benefit unmeasured), spermidine (null flagship trial), taurine (premise refuted), collagen (industry-funded evidence base), and everything sold as anabolic without a prescription.

Note what the maximum does *not* include. A maximal protocol is not 'every supplement' — it is every supplement that clears the bar, and the bar does not move because the budget did. Roughly two-thirds of the longevity aisle fails at any budget.

RCT / meta-analysisPrimary literature

The measurement column — where NAST genuinely beats Brut

This is the strongest argument for the maximal version, and it is the one nobody markets. Brut takes one blood panel a year. NAST takes four, plus imaging — and the value is not the individual reading, it is that four points make a trend and one point makes a guess.

  • Quarterly full panel: ApoB, Lp(a) once ever, fasting insulin, HbA1c, hs-CRP, full lipids, liver and renal, thyroid with free T3/T4, 25(OH)D, ferritin, B12, omega-3 index, RBC magnesium.
  • Annual: DEXA for body composition and bone density, VO₂max test (measured, not a wearable estimate), skin check.
  • Continuous: sleep staging, HRV, resting HR, daily weight at fixed conditions, steps.
  • Periodic: continuous glucose monitoring for two-week blocks rather than permanently — the goal is to learn your responses, not to watch a graph forever.
  • Every set logged, every session. Non-negotiable at either end of the spectrum.
The trap in dense measurement

More data makes the signal-to-noise problem worse, not better, unless the analysis accounts for it. Individual biomarker fluctuations in one person measured frequently will generate apparent trends indistinguishable from noise — which is exactly the criticism the field's most credible voices level at high-profile self-experimenters. The discipline that makes measurement worth doing: decide in advance what change would make you act, and ignore movements smaller than that.

What it costs

The bill, against Brut's

The number that should decide whether you run this, and the one most maximal protocols never print.

Excludes anything prescription or physician-supervised, which is age-gated here anyway and would add substantially. Excludes the ~3 extra hours a day, which is the larger cost and the one that does not appear on a bill.

Three to four times the money and roughly four times the time, for the portion of the dose-response curve where returns have most flattened. That is the honest trade, and printing it is the point — a maximal protocol that hides its cost is asking you to make the decision without the number that decides it.

Where the marginal pound actually goes furthest

If the budget is real but finite, the ranking is not what the supplement industry implies. Quarterly bloodwork (~£40/month) buys more than every added supplement combined (~£70/month), because measurement changes decisions and marginal supplements mostly do not. Sauna access outranks the entire supplement delta on evidence quality. And a DEXA once a year outranks a wearable, because one gives you a number you act on annually and the other gives you a number you look at daily and never act on.

The real limit

Where the levers fight each other

RCT / meta-analysisPrimary literature

Stacking is not additive

The naive maximal protocol assumes effects add. Several of these actively subtract, and the subtractions are mechanistic rather than anecdotal.

ConflictMechanismResolution
Endurance volume vs hypertrophyAMPK phosphorylates TSC2 and Raptor, inhibiting mTORC1, while also driving PGC-1α. One kinase, opposing consequencesSeparate by ≥6h; keep endurance intensity-biased and volume-light during growth blocks
Cold exposure vs liftingCold blunts the acute inflammatory and satellite-cell response and reduces the mTORC1 signalling the session generatedCold on non-lifting days, or ≥6h away. Heat carries no such conflict
Metformin vs training adaptationSuppresses the mitohormetic ROS signal that drives PGC-1α — the same suppression that makes it metabolically protectiveA genuine trade-off with no clean resolution. Physician-gated regardless
Antioxidant megadoses vs adaptationHigh-dose vitamin C and E blunt exercise-induced ROS signalling, which is the adaptation triggerGet antioxidants from food, not from grams of isolated vitamins
Two daily sessions vs sleepSecond session raises evening core temperature and sympathetic tone, both of which oppose sleep onsetFinish the second session ≥4h before bed, or drop it. Sleep outranks it
Dense measurement vs sanityNot physiological. Attention spent watching numbers is attention not spent on the behaviours the numbers measurePre-commit to what change triggers an action; ignore the rest

This is the actual ceiling on maximisation, and it is not willpower or money. Past a certain density, added levers start cancelling each other, and the marginal one costs more in interference than it delivers in effect. NAST is the point just before that — not the point past it.

The honest close

What NAST is actually for

Primary literature

Run it in seasons, not permanently

  • A defined block — 8 to 16 weeks — with a specific target and a date it ends. Open-ended maximisation has no success condition, so it can only fail.
  • A period with genuine slack: no exams, no launch, no travel. NAST does not survive contact with a bad month, and a collapsed protocol costs more than a smaller one held.
  • As a diagnostic. Run it clean, then remove one lever at a time and watch what actually degrades. Most people discover that four or five things were carrying the result and the other thirty were expensive theatre.
  • Never as an identity. The protocol funds the life; it is not the life. A person who has optimised themselves into having nothing to optimise *for* has failed at the only metric that was ever the point.

The most useful thing NAST produces is not the result. It is the list of what you can drop. Run the maximum once, deliberately, and you will find out empirically which levers were load-bearing — and that list is almost always closer to Brut's nine than to this page's thirty-five.

Research notes, not medical or financial advice. Every prescription or experimental item named here is named with its mechanism and its risk and without a dose, on purpose — several require physician supervision, several are unregulated, and several are inappropriate for a body that is still developing. Start from your own bloodwork and a doctor, never from someone else’s regimen.
