The categories of evidence behind everything we publish and supply.
Our content and product documentation draw on several distinct source types. We weight primary, peer-reviewed and regulatory sources most heavily, and are explicit when evidence is early or preliminary.
Primary research and reviews from indexed publications such as NEJM, The Lancet, Cell Metabolism and Nature Medicine.
Trial designs, endpoints and status pulled directly from ClinicalTrials.gov and equivalent national registries.
Public filings and guidance from the FDA, EMA and MHRA that establish a compound's approval status.
Third-party HPLC and mass-spectrometry certificates of analysis for the specific batches we supply.
Established textbooks and monographs used to describe receptor mechanisms and structure.
Qualified scientific reviewers who validate accuracy and framing before publication.
