Each product is scored 1 to 5 on six criteria, and the overall score is their plain average. Ties are listed alphabetically. Nobody pays for a place, and affiliate commissions play no part.
- Ingredients
- Whether the formula makes sense for what it is sold for, and anything in it that should not be.
- Evidence
- Human research behind the ingredients or method, at the amounts used, and any trial of the product itself.
- Transparency
- Doses, counts and company details on the label and site, and claims kept within the law.
- Value
- Real cost per day or per use, shipping included, against similar products.
- Guarantee
- Length of the refund window, what it covers and how easy it is to use.
- Ease of ordering
- One official store, clear one-time pricing, no hidden subscription, common payment methods.
