Andrew Steele & Ageless: The Complete Guide
Geroscience without a powder SKU — hallmarks, senolytics, and the clinic
Ageless (2021) is Steele’s civilian tour of aging as a biological target. Hallmarks, senescent cells, immune aging. This guide extracts the frame and sends you to Sinclair, Topol, and a physical — not a 12-bottle cart.

Key Takeaways
- 1Aging is the risk factor underneath the four killers — Topol still owns the 2025 clinic chapter
- 2Hallmarks are a map, not a shopping list
- 3Fisetin and NAD pages exist; they are optional, not the book’s homework
- 4ApoB, BP, walking, and lifting beat a senolytic tweet this year

Aging as the Target
Moderate EvidenceTreat only cancer or only plaque and you miss the shared biology. That is geroscience in one sentence. It does not mean you skip the cardiologist.
Hallmarks vs Cart
Emerging ResearchSenescence, mitochondria, immune aging are real research programs. Turning each into a bottle is how people go broke. See fisetin and NAD if you insist; stop at one experiment.
Keep vs Skip
Moderate EvidenceKeep: screening, lipids, walking, lifting. Skip: sourcing senolytics from a group chat because a hardcover named the pathway.

SupplementsDavid Sinclair & Longevity Science: The Complete Guide
Harvard geneticist David Sinclair changed public conversation with Lifespan (2019): aging as treatable, NAD+ and sirtuins as levers, fasting and cold as free drugs. This guide explains his research fairly, maps his personal stack, includes longevity-friendly recipes, and links Lifespan editions on Amazon.

Diagnostics & TestingEric Topol & Super Agers: The Complete Guide
Super Agers (2025) is Topol’s case that aging well is mostly not dying of the four chronic killers — and that incretins, earlier prevention, and better data are the real 2020s story. This guide extracts the clinic frame and sends you to GLP-1, ApoB, and Attia instead of a new powder.

SupplementsPeter Attia & Outlive: The Complete Guide
Peter Attia’s Outlive (2023) is the most useful popular longevity book of the decade: delay the Four Horsemen (atherosclerosis, cancer, neurodegeneration, metabolic disease) with exercise, lipids, sleep, and emotional health — not a supplement haul. This guide translates the book into a sequence you can actually run, and links the hardcover on Amazon.

SupplementsFisetin & Senolytics: Clearing Zombie Cells
Senolytics are compounds that selectively kill senescent ('zombie') cells — damaged cells that stop dividing but refuse to die, secreting inflammatory signals that accelerate aging. Fisetin, a flavonoid found in strawberries, showed the strongest senolytic activity in Mayo Clinic screens. Human data is early but the biohacking community treats fisetin pulses as a tier-2 longevity intervention.

SupplementsNAD+ & Longevity: The Complete Guide
NAD+ is one of the most critical molecules in human biology, essential for energy, DNA repair, and activating longevity pathways. Levels decline ~50% between ages 40–60. This guide explains what NAD+ does, whether supplementation works, NR vs NMN debate, and how to test your levels.

SupplementsRapamycin: The Complete Guide
Rapamycin (sirolimus) is an mTOR inhibitor with the strongest animal lifespan data in the NIA Interventions Testing Program. Longevity clinics now discuss intermittent, physician-supervised use. This guide covers the science, what human trials actually show, risks, and why it does not belong in a self-serve supplement drawer.
