Application overview

Source-labeled psilocybin and psilocin literature for search, monitoring, export, and citation workflows.

How the research index is built

Eight research sources feed Psilocybin-Research.com PubMed, OpenAlex, Crossref, Europe PMC, ClinicalTrials.gov, PsyArXiv, bioRxiv, and medRxiv provide records that are reconciled into the central research index. psilocybin-research.com PubMed OpenAlex Crossref Europe PMC ClinicalTrials.gov PsyArXiv bioRxiv medRxiv
Source records are fetched, reconciled, and labeled before appearing in the live index. The original sources remain authoritative.

Counts describe indexed registry records, not efficacy or total research activity. A trial can count under several conditions or countries. Unknown dates are excluded from the start-year chart; future years reflect planned starts. Stopped studies may reflect recruitment, funding or strategy and are not automatically treatment failures.
