Identify the exact product
Record the brand, variant, market, package size and official ingredient list. When comparing prices, use offers verified on the same date, in the same currency, and calculate cost using the same unit of volume or weight.
Separate the kinds of evidence
Record whether a study tested the actual product, another formula, an isolated ingredient or a laboratory model. For human studies, capture the population, comparison group, duration, outcome and funding or affiliations. Use those details to decide how narrowly to describe the result.
Describe the basis of each review
A label-based review uses packaging, published sources and verified retailer information. A hands-on review describes the actual test, who performed it, what was observed and any relevant limitations. The current preview contains no hands-on product reviews.
