The Peakspan Society
Healthspan for people who still have mountains to climb.
A virtual society for people building stronger, sharper, more useful years — through movement, measurement, food, recovery, exploration, and carefully chosen tools.
What is Peakspan Society?
Peakspan Society is a virtual club for active longevity. We are not chasing immortality, miracle supplements, or biological-age bragging rights. We are building strong, useful years through practical habits, evidence-aware tools, and a bias toward exploration.
The Five Pillars
Move
Strength, aerobic base, balance, mobility, and the ability to keep going.
Measure
The numbers that help you make better decisions: sleep, glucose, blood pressure, labs, and fitness signals.
Eat
Protein, fiber, metabolic health, vegetarian practicality, and fewer nutrition fairy tales.
Recover
Sleep, stress, sunlight, rest, and the discipline to not turn every day into a heroic mistake.
Explore
Travel, nature, photography, awe, purpose, and the long-game habit of staying curious.

FrontierER-100: The Aging Reversal Trial David Sinclair Can Actually Fail
For fifteen years, Sinclair's aging claims have lived in podcasts and press releases, immune to a real test. On June 9, 2026, a patient was dosed with ER-100 — a partial cellular reprogramming therapy with a falsifiable endpoint: can you see better afterward? Here's the science, the skepticism, and what a Phase 1 trial can and can't prove.
RecoverCold Water and the Breath: What Wim Hof Got Right, and What Can Kill You
Cold plunges and Wim Hof breathing are sold as one miracle practice. The recovery evidence is real, the general-health hype is thin, and the breathing technique has killed people when mixed with water. Here's the honest version — and two protocols kept deliberately apart.
FrontierKPV: The Three-Amino-Acid Anti-Inflammatory With a Replication Problem It Doesn't Have
Most Frontier peptides rest on one lab's work. KPV is different — two independent groups, decades of consistent anti-inflammatory data, a clean mechanism. And still zero completed human trials. Here's what that combination means.
FrontierMOTS-c: The Exercise You Can't Inject
MOTS-c is a peptide your own mitochondria make when you exercise. That's what makes it scientifically fascinating — and exactly why 'exercise in a vial' is the wrong way to think about it. What the mitochondrial-derived peptide research actually shows.
