Peptide Library

Peptide Library (https://peptidelibrary.app) is a free research resource that indexes published evidence for peptides and related compounds. It matches PubMed (MEDLINE via Europe PMC) and ClinicalTrials.gov records to each library entry by name, synonyms, and aliases, then assigns study types and evidence classes from publication types and MeSH, with editor review for uncertain cases. Live research pages, open methodology, and downloadable CC BY 4.0 datasets (CSV and JSON, edition 2026.1) are available at https://peptidelibrary.app/research and https://peptidelibrary.app/research/data. A free, read-only remote MCP server and public API give AI assistants and developers structured peptide research profiles, evidence tiers with cited sources, and comparisons (https://peptidelibrary.app/developers/mcp, https://peptidelibrary.app/developers). There is also a public peptide price index at https://peptidelibrary.app/peptide-prices for non-editorial use. Peptide Library is research and educational use only — not medical advice, not dosing guidance, and not a substitute for professional care. It is published by Superfime LLC. Keywords: peptides, PubMed, ClinicalTrials.gov, evidence classification, bibliometrics, open data, MCP, research API.
For researchers, the library is intended as a starting point for locating and organizing published and registered work, not as an endorsement of any compound. Linking each matched record back to its source gives readers a way to check context and interpret findings independently. Names, synonyms, and aliases help connect records to the corresponding library entry, while the evidence classes and study-type labels provide a consistent way to browse materials across the directory. The methodology explains the matching and classification approach, including the use of publication types and MeSH and the role of editor review when an assignment is uncertain. This makes it possible to see how a classification was reached rather than treating it as an unsupported conclusion.
The downloadable CSV and JSON editions are designed for people who want to explore the listed material in their own tools, compare entries, or build reproducible research workflows. The open data is released under CC BY 4.0; users should retain appropriate attribution when redistributing or adapting it. Developers can query the public API or connect through the read-only remote MCP server to retrieve structured profiles, cited evidence tiers, and comparisons. The MCP service is read-only and is intended to make the same research information accessible within AI-assisted workflows. Live research pages and the documentation describe these resources and their intended use.
Peptide Library supports research and education. It does not provide medical advice, dosing instructions, or individualized recommendations, and its evidence organization should not be taken as proof that a peptide is safe or effective. Consult the original source records for full context and seek qualified professional guidance for health questions. The public peptide price index is offered separately for non-editorial reference. Peptide Library is published by Superfime LLC.
