How Codex curates products
Every product passes three checks before it reaches you.
Brand discovery
We surface brands operators and coaches are already buying — never paid placement.
Wellness review
Each SKU is scored against our charter: ingredient quality, evidence, claims, sourcing.
Operator-tested
Coaches and studios in our network try it on real clients before we recommend it.

Eight Sleep Pod 4: a EUR 2,500 way to fix something a window can fix
The temperature science is real. The price, lock-in, and software subscription are extreme. Worth it for a narrow band of buyers who genuinely can't cool their bedroom.
Guide
Whoop 4.0: the screenless coach that bills you forever
Whoop's strain-and-recovery model is genuinely useful — but the subscription model and screen-free design are not for everyone. Worth it if you'll actually train to the score.
Guide
Apple Watch Series 10: the best general-purpose watch is finally a real sleep tracker
Sleep tracking on the Series 10 is finally good, and the sleep apnea detection is genuinely useful. But the ecosystem lock-in and the daily charging are the real story.
Vetted under the Codex charter
We only stock products that pass our ingredient, evidence and sourcing review. If a SKU stops meeting the bar, it's delisted — full stop.
