Biohacking on a budget: the free PDF guide
A printable copy of everything we've compared: 15 famous premium products (saunas, cold plunges, red light, sleep, rings and trackers, water filters, recovery), the cheaper options that do the same job, and what you give up with each one.
What's inside
- The short version: every premium pick next to the alternative we feature, and the price difference
- Every comparison, category by category, with trade-offs and Renvo Scores (or what's still unverified)
- Subscription maths: the memberships some premium products need or push
- The only products that have earned a score so far, and why most haven't
- A 60-second checklist before you buy any cheaper alternative
Same data as our comparison pages: US prices from the sellers' own pages, sources linked. No health claims, no invented test results. We don't test products hands-on.
