Review methodology
Last updated: May 2026
Every product we review is scored on the same four dimensions, on a 1–5 scale each. We then weight them based on category — for example, third-party-testing weighs heavier for supplements than for fitness equipment. The composite score appears at the top of every review.
Efficacy
Does the product do what it claims? We grade against peer-reviewed evidence for the active ingredient(s), dose, and delivery format — not against marketing copy. Inert or under-dosed products get an honest low score.
Value
Cost per active dose, cost per serving, cost per scientifically meaningful unit. We compare to category alternatives. Premium pricing is fine if the product earns it.
Quality / label honesty
Is the formula transparent? Is it third-party tested by an independent lab (USP, NSF, Informed Sport, ConsumerLab)? Are the doses on the label what's actually in the bottle? Proprietary blends with hidden doses get downgraded.
UX
Taste, texture, smell, package, ordering experience, subscription cancellation experience. The best product on paper doesn't help if you stop taking it after three days.
What we don't score
We don't score products on brand story, founder credentials, marketing aesthetic, or influencer endorsements. We don't accept payment for higher rankings. Our affiliate relationships are disclosed; commissions never influence the score.
When a product doesn't earn a recommendation
We'd rather leave a category empty than recommend a product that doesn't meet our bar. “Best of” lists may include a “Skip” section when the category is full of low-evidence options.
