Reviews can reveal useful information about communication, delivery or order resolution. They are much weaker evidence for chemical identity, reproducibility or safety, particularly when the reviewer cannot verify the material or describe the conditions of use.

The FTC's consumer-review guidance addresses deceptive review practices and the importance of truthful presentation. It also distinguishes a review from a testimonial used in advertising. A reader should therefore consider both the content and the commercial context in which it appears. FTC consumer reviews and testimonials rule questions

Ask what the reviewer could know

A person can directly observe whether a parcel arrived on time. They usually cannot infer a full impurity profile from appearance or a subjective response. Those statements belong in different evidence categories even if they appear in the same five-star review.

Verification of a purchase does not verify a scientific claim. Nor does a large number of similar anecdotes create a controlled experiment. People may differ in expectations, concurrent exposures and what they choose to report. These limitations apply to favorable and unfavorable reviews alike.

Look for conflicts without guessing

Discounts, affiliate relationships or a connection to the seller can affect interpretation. A disclosed relationship should be recorded; an undisclosed relationship should not be invented merely because a review is enthusiastic. When independence cannot be established, say that it remains unknown.
