Last meaningful update: 9/20/2026

Evidence searched through:: Not recorded
Assessment updated:: 9/20/2026
Documented human review:: No documented human review recorded
Automated scientific assessment:: None recorded
AI source check:: 9/26/2026

Published source links and profile text pass separate gates. Only a documented human review is labelled as human review; an automated scientific assessment applies deterministic checks, and an AI source check confirms only that a source exists and matches its identifiers. A source count alone does not establish a review.

Evidence coverage has three distinct layers. The corpus count is a transparent screening inventory, the featured set contains study-level tiering and interpretation, and the published-source count contains records promoted through the institutional publication workflow. Source validation, editorial publication, and scientific appraisal are separate decisions; these numbers must not be merged.

Ranked research corpus

291

Categorized publications with provisional ranking; scientific review remains separate.

Featured tiered studies

Cornerstone publications with study-level interpretation, limitations, and tier disclosure.

Research domains

Clinical and scientific questions synthesized independently across the evidence atlas.

Published source records

Database records promoted through the governed publication workflow—not the corpus total.

Corpus generated 2026-09-18. Counts remain separately labeled so screening is not represented as completed review.

Human experience · separate evidence stream

No community pattern is displayed yet

Eligible observations remain below the privacy and reliability threshold. WPF will not convert a handful of reports into a percentage, trend, or clinical claim.

Observation is valuable human context. It is not evidence of causation, efficacy, or safety.

What we know

Evidence, claims, and boundaries

The project separates represented evidence from qualification, contradiction, uncertainty, and what the evidence does not establish.

Reconciled domain conclusions

5 published domain syntheses connected to 0 featured studies

Semax no longer relies on the legacy “no public claim” state. Each research domain publishes a bounded synthesis, confidence level, evidence context, limitations, geographic applicability, regulatory interpretation, and research gaps. Publication of these syntheses is separate from the scientific review status shown above.

Read the scientific record with its boundaries intact

The public record organizes reviewed evidence; it does not establish scientific truth by itself.

Association, mechanism, observation and regulatory status must not be represented as proof of clinical efficacy or safety.

Observational reports describe contributor experiences and cannot establish causation, effectiveness, safety or clinical benefit.

Contradictory and qualifying evidence must remain visible rather than being silently discarded.

Absence of represented evidence is not evidence that research does not exist.

Research gaps identify unresolved questions; they are not negative conclusions.

Regulatory status is distinct from scientific evidence quality.

Media relationships provide context and explanation; they do not increase the strength of scientific evidence.

A section with no represented records is an incomplete project record, not a scientific conclusion.

Researcher and institutional relationships are shown only when supported by represented records and must not be interpreted as rankings or endorsements.

Semax evidence · ranking key

How evidence is ranked

A tier describes the evidentiary role and design strength of a source. It is not a popularity score, proof that every conclusion is correct, or a substitute for claim-level review.

Practice-defining evidence

Large, well-conducted randomized trials; prespecified major outcomes; rigorous systematic reviews or meta-analyses; and major regulatory assessments.

Strong supporting evidence

Smaller randomized trials, strong prospective cohorts, prespecified secondary analyses, and high-quality comparative-effectiveness studies.

Contextual evidence

Retrospective cohorts, claims-database studies, pharmacovigilance analyses, mechanistic human research, and well-documented case series.

Signal-generating evidence

Case reports, conference abstracts, preclinical research, hypothesis-generating analyses, and expert commentary.

Tier and confidence answer different questions

Tier classifies source design and evidentiary role. Confidence reflects risk of bias, sample size, comparator quality, outcome relevance, follow-up, missing data, directness, replication, reporting quality, and whether conclusions stay within the measured results.

Funding and conflicts are disclosed and considered, but sponsorship never automatically changes a tier. Corrections, retractions, and expressions of concern override the original rating.
