Evidence before conclusions
Prefer original research for study findings, regulator records for authorization and official chemistry records for identity. Reviews can provide context, but should be described as reviews. Explain the study population, exposure route, formulation and endpoint before drawing a conclusion. An animal result does not establish human benefit; a registered trial does not establish a positive result.
What our citations mean
Guide bibliographies link primary studies, official records and standards to relevant sections. Each entry states its evidence type or limitation. These are selected source lists, not systematic reviews or a guarantee that every sentence has been independently verified. A paper about one compound, species or preparation should not silently support another.
Review and publication dates
An individual review date describes a recorded review of that page. Pages without a recorded date display that limitation. Automated imports, deployment dates and registry snapshot dates are not scientific review dates. Bibliography maintenance alone does not justify replacing a page's review date.
Authorization is product-specific
Describe the regulator, jurisdiction, product and indication. Health Canada warnings about unauthorized products do not prove worldwide nonapproval of a molecule. An approved pharmaceutical formulation does not validate a research vial bearing the same ingredient name.
Tools and uncertainty
Calculators explain arithmetic and COA checks flag inconsistencies in entered data. They cannot certify a material, determine a personal dose or provide a preparation protocol. Missing or conflicting identity data should remain visible as uncertainty rather than being filled with plausible estimates.
Corrections and the next reviews
Report a specific statement with its page address and supporting source. Substantive corrections should identify the changed claim and distinguish a correction from a complete review. Further profile expansion should start with verified identity, primary human and preclinical evidence, and unresolved questions, rather than a target word count.
