Media summary
Peptide Library is an educational peptide research library. Its Research Intelligence Center counts the published science behind the peptides in the library: PubMed publications and registered clinical trials, classified by study type and evidence class, with human, animal and laboratory research kept apart. Numbers come from frozen, versioned datasets, and an editor approves every figure in a report before it is published.
What the numbers measure is research activity: how much has been published and what kind of study it is. They do not say whether a peptide works or is safe, and Peptide Library gives no medical or dosing advice.
Latest report: State of Peptide Research 2026, edition 2, published November 6, 2026, data through September 30, 2026.
