Every claim links to peer-reviewed studies. We separate evidence from marketing language on every single page.

We grade evidence using four tiers: RCT meta-analyses, individual RCTs, observational data, and mechanistic research. A claim that appears only in animal studies is labelled accordingly — not promoted as settled science.

No brand pays for placement. Every score is determined by our methodology, not commercial relationships.

We decline review samples and sponsored content. Products are purchased on the open market at retail price, identically to how a consumer would buy them. Affiliate links are disclosed on every page — they never influence scores.

We review ingredients before products, not the other way around.

Each ingredient in our library is profiled for mechanism, effective dose from clinical data, and known interactions before any product containing it is rated. A product can only score well if its ingredients are dosed at levels shown to work.

Content is organised by your health goal, not by category or brand.

Rather than grouping by product type, every review, ingredient page, and research brief links to the goals it actually supports. A creatine review surfaces in Muscle Gain, Recovery, and Cognitive Performance — wherever the evidence points.
