HackedSelf (hackedself.com) is a biohacking and longevity publication built on a simple discipline: treat every health claim like a security disclosure. Nothing gets recommended until the evidence, the dose, and the failure modes are on the table. The site publishes protocols, supplement-stack breakdowns, and gear reviews for people who want measurable results, not marketing.
That audit-first method shows up most clearly in the site's coverage of the XPRIZE Healthspan competition. Rather than reposting the press release, HackedSelf read the actual rules and scored the first 90 days of results against them: what the AgelessRx cohort actually measured, how a 90-day pilot differs from the 12-month scoring window the prize intends, and what a reader can and cannot conclude from the early data. The takeaway was not hype or dismissal but a narrow, defensible verdict, which is the house style.
Protocols get the same dosing rigor. The sauna cardiovascular series asks whether sauna sessions can replace Zone 2 cardio and answers with a minimum effective dose: four sessions per week above 175 degrees Fahrenheit, with the cardiovascular markers each session moves. Zone 2 training for lifters is written as an actual prescription, heart-rate bands and weekly volume included, instead of the usual vague encouragement to move more. A strength-training piece explains why grip strength, gait speed, and lower-body power are the three tests that best approximate your muscle age, and how to run them at home.
The gear reviews run on cost math. The home-sauna comparison calculates the running cost per session of a home unit against a gym membership with a cold plunge and sauna lounge, then finds the break-even point in sessions and years. Reviews of recovery gear, sleep equipment, and supplements all carry the same cost-per-use framing, because a protocol you cannot afford to sustain is not a protocol.
Supplement and pharmacology coverage is deliberately narrow. The semaglutide piece accepts that the longevity evidence is real but stresses how narrow it is, including the caveat that much of the underlying data comes from HIV-patient cohorts and may not generalize. Every stack recommendation ships with n=1 caveats: what the studies show, what is plausible extrapolation, and what is a self-experiment with no control arm at all.
The readership is people who already train, already track sleep, and are tired of longevity content that ends in a supplement affiliate link. HackedSelf is free, carries no paywall, and publishes on a steady cadence across Longevity, Sleep, Nutrition, Fitness, and Recovery.
