At a glance
What the public record shows.
Peptide research spans a large body of indexed literature and a substantial number of registered studies. The counts below are search results from public databases, not estimates of unique compounds, products, or outcomes. Database records change as entries are added, corrected, or reclassified.

Counts need context.
Literature records are indexed entries. A PubMed count reflects records that match the stated search, including records added or updated over time. It is not a count of unique experiments, authors, or peptide sequences.
Study registry records are registrations. A clinical study record may describe an interventional, observational, or other registered study. Its presence in the registry does not establish the quality, outcome, or applicability of the study.
Search terms set the boundary. The figures use the exact public searches named below. That makes each number checkable, while also making clear that a broader or narrower search can return a different result.
