Free newsletter · Biohacking & longevity

What actually works for living longer, one study at a time.

Every week, one email takes apart a molecule, a protocol or an anti aging technology. We read the studies, and we tell you plainly what is demonstrated, partial or still hypothetical. Free, and it will stay that way.

What you get

One email a week. Nothing else.

01

One subject a week

A molecule, a protocol, a technology or a widely held belief. One only, taken apart properly.

02

The level of evidence, stated plainly

Every claim is placed: what is demonstrated in humans, what remains partial, what is still a hypothesis.

03

Under ten minutes

Sources are cited, study limits explained. You decide from there.

Our method

Decode, analyze, inform.

  1. 1

    Back to the papers

    We go back to the cited studies: protocols, populations tested, doses, length of follow up.

  2. 2

    Level of evidence

    We separate human clinical results, preliminary findings, and what is still at the animal or theoretical stage.

  3. 3

    The whole file

    Methodological limits, conflicts of interest, grey areas. Everything you need to make up your own mind.
