Longevity & Healthspan

Extend healthspan via AMPK / SIRT1 / NAD+ axis activation, mitochondrial support, and senescent cell clearance

⚠ Research synthesis · NOT medical adviceFind a qualified physician to supervise. See referral panel below.

§ Abstract

This protocol synthesizes peer-reviewed evidence across six biological pathways implicated in healthspan extension: AMPK activation, NAD⁺ coenzyme availability, SIRT1 deacetylase activity, mitochondrial function, telomere maintenance, and senescent cell clearance. None of these compounds is FDA-approved for life extension; the evidence base for the OUTCOME (extended healthspan in humans) remains immature, even where individual compound mechanisms are well-characterized in animal models. The protocol is offered as a research synthesis to be implemented under qualified clinical supervision — not as a self-administered regimen. The honest read: the mechanistic rationale is strong, the human-outcome data is thin, and the right way to engage with it is with a physician who can baseline-test, monitor for harms, and adjust based on individual response.

§ Pathways targeted

Six biological
pathways.

Each compound in the protocol acts on one or more biological pathways implicated in aging biology. The combined intent: hit multiple complementary pathways rather than overfit a single target.

AMPK activation

AMPK is the cellular energy sensor. Activation mimics caloric restriction signaling, promotes mitochondrial biogenesis, and inhibits anabolic pathways tied to aging.

Compounds at this target

  • MOTS-c
  • 5-Amino-1MQ
  • SLU-PP-332

NAD⁺ optimization

NAD⁺ is the essential coenzyme for sirtuin activity and DNA repair. Tissue NAD⁺ declines ~50% by age 60. Direct supplementation and precursor strategies both pursued.

Compounds at this target

  • NAD⁺ injectable
  • NMN (ref)
  • NR (ref)
  • 5-Amino-1MQ

SIRT1 / sirtuin activity

Sirtuins are NAD⁺-dependent deacetylases that regulate metabolism, stress response, and longevity pathways. Activation requires both adequate NAD⁺ and direct SIRT1 stimulation.

Compounds at this target

  • Resveratrol (ref)
  • Pterostilbene (ref)

Mitochondrial function

Mitochondrial decline is a hallmark of aging. Targets include cardiolipin protection (SS-31), uncoupling-mediated efficiency (BAM15), and electron transport support (Methylene Blue).

Compounds at this target

  • SS-31 (Elamipretide)
  • BAM15
  • Methylene Blue

Telomere maintenance

Telomere shortening contributes to replicative senescence. Epitalon has been studied for telomerase activation; human outcome data is limited.

Compounds at this target

  • Epitalon

Senescent cell clearance

Senescent cells (zombie cells) accumulate with age and secrete pro-inflammatory cytokines (SASP). Pulse-dosed senolytic compounds aim to selectively clear them.

Compounds at this target

  • Fisetin (ref)
  • Quercetin (ref)
  • Dasatinib + Quercetin (ref, clinical Rx)

§ The protocol

Five phases,
sequenced.

Sequencing is informed reasoning, not RCT data. Foundation first; layer pathway-active compounds in over time. Each phase assumes the previous is in place.

  1. 01

    Foundation

    Weeks 0–4

    Establish baseline labs, build redox and coenzyme reserves before adding pathway-active compounds.

    • Glutathione

      Role

      Antioxidant / redox baseline

      Dose range

      200–600 mg

      Role

      Decision point for the next 6-month block

      Dose range

      Frequency

      Every 6 months

      Note · Compare against baseline and 3-month interim labs. Discontinue or modify any compound with a negative trend.

§ Clinician monitoring

What gets
measured.

If you cannot get these labs done by a qualified physician on this cadence, this protocol is not appropriate for you. You cannot run an unmonitored experiment on yourself.

  1. Baseline (week 0)

    Establishes the personal baseline against which all protocol effects are measured. Without this, you have no way to know if the protocol is helping, neutral, or harming.

    • CBC with differential
    • Comprehensive metabolic panel (CMP)
    • Fasting glucose, insulin, HOMA-IR
    • Hemoglobin A1c
    • Lipid panel + ApoB + Lp(a)
    • hsCRP
    • Vitamin D, B12, ferritin
    • TSH + free T4
    • Total + free testosterone, SHBG, estradiol
    • IGF-1
    • NAD⁺ level (if assay available)
    • Epigenetic age clock (GlycanAge, DunedinPACE, or similar)
  2. Every 3 months

    Catches early signals — liver/kidney stress (CMP), inflammatory shift (hsCRP), insulin resistance (HOMA-IR delta), or unintended IGF-1 elevation that could promote tumor growth.

    • CMP
    • Fasting insulin
    • hsCRP
    • ApoB
    • IGF-1
  3. Every 6 months

    Evaluates trajectory on the outcome metrics that matter (epigenetic age, body composition, full metabolic picture). Decision point for continuation.

    • Full baseline panel
    • Epigenetic age clock
    • Body composition (DEXA preferred)
  4. Annual

    Standard preventive medicine alongside any longevity protocol. Worth doing whether or not you pursue this protocol.

    • Cardiac calcium score (age 40+)
    • Age-appropriate cancer screening (colonoscopy, mammography, prostate, skin)
    • Cognitive assessment baseline (e.g., MoCA)

§ When NOT to attempt this

Contra-
indications.

These are absolute or strong relative contraindications. None of them is exhaustive — a qualified physician will identify additional individual factors.

  • Active malignancy or recent cancer history — many compounds in this protocol have angiogenic or growth-signaling activity that is theoretically problematic with active disease.

  • Pregnancy or breastfeeding — none of these compounds has been adequately studied in pregnancy.

  • Significant renal or hepatic dysfunction — clearance is impaired; dose adjustments and additional monitoring required, ideally avoid.

  • Bleeding disorders or active anticoagulation — discuss timing with prescribing physician.

  • Concurrent serotonergic medications + Methylene Blue — serotonin syndrome risk; do not combine.

  • Known peptide hypersensitivity — test dose and supervision required.

  • Children and adolescents — none of this is appropriate for developing physiology.

§ Honest gaps

What we don’t
know yet.

  • !

    Whether a multi-compound longevity protocol produces measurably greater healthspan extension in humans than any single compound — almost no head-to-head or factorial human trial data exists.

  • !

    Whether the surrogate endpoints we monitor (epigenetic age, IGF-1, hsCRP) actually predict mortality or healthspan in individuals — population-level associations exist; individual prediction is uncertain.

  • !

    Optimal sequencing and cycling of AMPK / NAD⁺ / mitochondrial / senolytic interventions — current sequencing is informed reasoning, not trial data.

  • !

    Long-term safety of chronic NAD⁺ pool elevation in adults — most NAD⁺ longevity data is in animals or short-term humans.

  • !

    Whether the angiogenic and growth-supportive effects of several included compounds are net-positive or could accelerate occult tumor growth in some patients.

  • !

    Drug-drug interactions across this many simultaneously-administered compounds are largely uncharacterized.

§ Required clinical handoff

Find a qualified
physician.

This protocol is research synthesis, not a prescription. Before initiating any compound: identify a physician with relevant subspecialty expertise who will baseline you, supervise initiation, monitor for harms, and adjust based on individual response. The compounds in this protocol are not FDA-approved for healthspan extension; legitimate clinical use is necessarily off-label and must be physician-directed.
