The standing rules

Mechanism before advice. If we cannot explain why something works, we do not tell you to do it.
No hero ingredient. Nothing here will be sold to you as the molecule that changes everything.
No affiliate links, ever. We sell one thing, it is on the front page, and it is not a cream.
We name the limits. Sample size, funding, and whether it was tested on humans or on cells in a dish.
