Evidence decisions
Retailer says safe, manufacturer says remove: document the disagreement

Do not settle a contradiction by counting pages
Several shops repeating a claim do not make it a manufacturer instruction. FishyMag gives manufacturer evidence priority for affirmative compatibility statements. A retailer page may help identify a discrepancy but cannot establish safety. Nor should a forum anecdote erase an explicit restriction just because its outcome sounds reassuring.
Check whether the sources describe the same thing
Write each statement beside its URL, date, market, formulation and route. A disagreement about two different bottles is an identity problem before it is a verdict problem. Keep qualifying phrases intact. A claim that applies only under specified conditions should not be compared with an unqualified summary as though they were identical.
Escalate with both passages
Send the manufacturer the conflicting wording and photographs of your bottle. Ask which instruction applies to that formulation and which groups it explicitly covers. Until clarified, do not choose the answer that makes purchasing easier. Record the response with its conditions and the original contradiction; an unexplained screenshot of “support said yes” is not enough for another reader to assess the conclusion.
Put it into practice
Your checklist
- Capture exact wording and source identity.
- Match market, formulation and administration route.
- Keep the restrictive guidance visible while seeking clarification.
Sources and scope
This article distinguishes manufacturer statements from FishyMag’s own workflows and arithmetic examples. Linked formulation records retain their own evidence dates; publishing this article does not refresh those records.

FishyMag reports what manufacturers say, quoted and linked. It does not diagnose illness or recommend a treatment, and it never infers that a product is safe from the absence of a warning — where no statement exists, it says so.
Formulations change. Always read the label on the bottle in your hand, and contact the manufacturer if your tank contains anything valuable or unusual.
