HackedSelf

HackedSelf is practical biohacking for longevity, written like an evidence audit instead of a hype feed. Every protocol is dosed like a protocol: exact numbers, real costs, and the caveats an n=1 experiment deserves. The flagship pieces show the method. Can a Sauna Cardiovascular Protocol Replace Zone 2? works out the minimum dose - four sessions above 175 degrees Fahrenheit - before sauna heat can stand in for aerobic base work, and says plainly where the substitution breaks down. Strength Training for Longevity Tests Your Muscle Age explains which tests actually measure aging muscle: grip strength, gait speed, and lower-body power, and why they beat how much you lift. Semaglutide Longevity Evidence Is Real but Narrow takes the most-hyped drug result of the decade and sizes it honestly, including the caveat that much of the longevity-relevant data comes from HIV-patient cohorts, not healthy adults. XPRIZE Healthspan Results, Audited Against the Rules checks a headline longevity competition against its own scoring - 90-day outcomes versus the 12 months the rules promise - and publishes the gap. The same discipline covers money math: Home Sauna Running Cost per Session vs the Gym Lounge prices the at-home heat habit per session and finds the break-even point, so readers know what the protocol costs before they believe the benefits. Zone 2 Training for Lifters, Dosed Like a Protocol translates zone-2 cardio into a plan a strength athlete will actually run, with session counts and intensity borders instead of vibes. The house rules are consistent across Longevity, Sleep, Nutrition, Fitness, and Recovery: cite what the evidence claims, never inflate an effect size, flag every n=1, and show the dose. The audience is people who self-experiment but want receipts - readers who would rather see the audit than the affiliate link. Sleep and recovery coverage follows the same audit habit, and every review states what the evidence claims and what it merely suggests, so the reader can judge the strength of each claim instead of trusting a headline. The result is a site that treats self-experimentation as a discipline with a paper trail.

What problem it solves

Most biohacking content sells certainty the studies do not contain: supplement stacks with inflated effect sizes, protocols with no dose, gadget reviews with no cost-per-use. Readers who want to experiment on themselves get marketing, not evidence, and no way to tell which claims would survive an audit.

Alternatives & competitors

Where typical biohacking blogs chase hype, HackedSelf audits: minimum effective doses (four sauna sessions above 175F), honest evidence scoping (semaglutide's narrow HIV-cohort base), competition scoring checked against the rules (XPRIZE Healthspan), and per-session cost math (home sauna vs gym lounge). Every piece states its effect sizes, its costs, and its n=1 caveats in plain numbers.
