Peptide research statistics
Current, citable figures on biomedical literature, registered clinical study records, and the broader U.S. research environment.
Last updated September 2, 2026
At a glance
A practical snapshot of research activity.
These figures are designed as a starting point for writers, researchers, and teams who need a concise view of peptide-related research activity. Each statistic links to the named source and includes the date or access date needed to interpret it responsibly.
Database search counts change as records are added or updated. They show the size and activity of a searchable research record, not the safety, effectiveness, approval status, or quality of any specific compound.

How to read this page.
PubMed figures use the National Library of Medicine database. The peptide-specific totals use the exact title-or-abstract search linked with each statistic. ClinicalTrials.gov figures use its public search interface and status filters. The research spending figures come from the National Center for Science and Engineering Statistics 2023-2024 national update.
This page is reviewed monthly, or earlier when a key source publishes an update. The statistic anchors above are kept stable so a citation can continue to point to the relevant figure.
