The only peptide app
you can actually trust

AmericanPeptide.com is an AI-assisted research platform and open reference for peptide science. It pairs a citation-backed research assistant — the Peptide Agent — with an open catalog of research peptides, hands-on calculators, and synthesis guides, all grounded in public datasets like PubChem, UniProt, PubMed, and ClinicalTrials.gov.

No. AmericanPeptide.com is a reference and research platform — not a pharmacy, vendor, or store. We publish chemistry, mechanisms, and evidence so researchers can make informed decisions; we do not sell compounds or take orders.

No. Everything on the site is for computational research and education only. It is not medical advice, diagnosis, treatment, or a dosing protocol, and AI-generated output is a hypothesis that requires independent experimental validation. Always consult a qualified professional and follow applicable laws.

The Peptide Agent answers from primary sources, not guesswork. It grounds responses with live tools across PubChem, UniProt, PubMed, and ClinicalTrials.gov, and shows its citations so you can trace every claim back to the original record.

A certificate of analysis (COA) is the third-party lab report documenting a peptide's identity and purity — typically by HPLC and mass spectrometry. Purity matters because impurities and truncated sequences can confound results, so reading the COA is how you separate a clean compound from a questionable one.

Yes. The peptide catalog is open data under Creative Commons Attribution 4.0 (CC BY 4.0) — free to read, query via the API, and redistribute, including commercially, as long as you credit AmericanPeptide.com. There is also a JSON API, markdown twins, and an MCP server for agents.

Reconstitution is a dilution calculation: the final concentration depends on the mass of peptide in the vial and the volume of solvent (usually bacteriostatic water) you add. The reconstitution calculator does the math and shows the draw volume for a target amount.
