Signal integrity,on the record.
This is how Nexus selects sources, scopes research-context claims, separates general information from lot-specific COA evidence, publishes updates, and corrects errors.
- Published
- Last updated
01 / Evidence hierarchy
Strength follows scope.
Nexus uses a public batch record before primary literature, and primary literature before neutral references, when those sources address the claim being made. The hierarchy never makes one source answer a question outside its scope.
Scope rule
A COA cannot establish a biological mechanism. A paper cannot establish the purity or identity of a Nexus lot. Each claim stays attached to the source capable of supporting it.
- 01
Public batch record
Lot-specific evidenceControls statements about a named Nexus lot: its batch identifier, reported test date, methods, and results shown on the public record.
If the public record does not name a laboratory, accreditation, reviewer, chain of custody, or source report, Nexus does not infer one.
- 02
Primary literature
Research contextSupports general statements about compound identity, experimental models, molecular targets, and findings reported by the original researchers.
- 03
Neutral reference
Reference contextSupports stable identifiers, nomenclature, and orientation when a primary paper or public batch record is not the right source for the claim.
02 / Source selection
A citation is not automatically evidence.
Selection starts with direct relevance, stable identification, and an explicit experimental context. When sources disagree or do not support the requested precision, Nexus narrows the claim, states the uncertainty, or leaves it unpublished.
Selection checks
- The source addresses the exact compound, analog, form, or lot described.
- The model is identified: in-vitro, animal, observational, or clinical findings are not blended together.
- The original methods and results are preferred over a summary of them.
- A stable title, date, identifier, or institutional record allows the source to be found again.
- Limitations and uncertainty remain visible when they materially change interpretation.
Not sufficient alone
- Search-result snippets, forum posts, social posts, or unsourced summaries.
- Reseller and manufacturer marketing used as independent scientific corroboration.
- A certificate from another vendor or another lot used to describe a Nexus batch.
- A review article used to overrule the methods or results in the primary work it summarizes.
- A source whose compound identity or experimental context cannot be matched to the claim.
03 / Fact-check and update process
Every claim gets a boundary pass.
- 01
Frame the claim
Classify it as lot-specific evidence, general research context, or Nexus policy before selecting a source.
- 02
Match scope to source
Check that the source addresses the exact compound, form, model, and level of certainty described on the page.
- 03
Run the boundary pass
Remove unsupported inference, human-outcome language, dosing, administration, and medical or veterinary guidance.
- 04
Publish the date
Show when substantive content was last changed. Layout-only work does not reset the content date.
A substantive source correction, changed policy, revised batch record, or material change in meaning triggers a content-date update. Styling and layout changes do not claim fresh research review.
The page-level date records when this page changed. It does not imply that every linked source, product, or batch record was updated on the same day.
04 / Evidence boundary
Context and certificate are separate lanes.
General research information can explain what a compound is and how it has been studied. Only a current, named public batch record can describe the evidence Nexus publishes for that lot.
Lane A
General research context
- Identity, nomenclature, and research classification.
- Molecular targets and experimental findings reported in the cited model.
- Clear distinction between in-vitro, animal, and clinical contexts.
This lane does not prove the identity, purity, quantity, or condition of a product or lot.
Lane B
Lot-specific COA evidence
- The batch identifier, reported test date, methods, and results visible on that record.
- Status labels that distinguish published evidence from a pending record.
- Scope limited to the named lot; evidence is not transferred to another batch.
This lane does not establish safety, efficacy, a clinical outcome, or an undisclosed laboratory or reviewer.
05 / Faceless accountability
Trust without a fictional lab coat.
Nexus does not create fictional author, reviewer, scientist, or laboratory profiles to manufacture authority. A page may identify Nexus Laboratory as its publisher; organizational authorship is not a personal credential or independent review.
We do not imply a reviewer, credential, laboratory location, accreditation, or named partner when that information is not part of the public record. The trust signals are the source trail, claim scope, visible dates, lot evidence, and correction path.
Correction channel
Put the disputed claim on the record.
Send corrections to support@nexuslaboratory.org. Include the page URL, the exact passage, the source you believe controls the claim, and the requested correction.
- 01LocatePage or lot record
- 02DocumentPassage and source
- 03CorrectMeaning and date
Confirmed substantive corrections change the page and its visible updated date. When the prior wording needs ongoing context, a correction note is added rather than silently changing the meaning.
06 / Research-use-only boundary
Context, never medical guidance.
Nexus products and site content are for in-vitro research use only. They are not for human or veterinary use. We do not provide dosing, administration, diagnosis, treatment, therapeutic-outcome, or medical guidance. Research mechanisms described from sources are context, not recommendations or claims about human outcomes.
