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 does not sell peptides or take orders; our role is to help you evaluate a source, not to be one. We publish the chemistry, the evidence, and the criteria that separate a trustworthy vendor from a questionable one, so wherever you buy you can judge it on its COA, third-party testing, and purity. Where we do point you to an outside vendor it is a clearly disclosed affiliate referral, and we may earn a fee if you buy through it, at no extra cost to you. The ranking itself is never for sale — it comes only from published transparency signals. A partner can pay for a prominent slot above that ranking, but it is always labeled "Featured partner," it still shows its own unedited trust score, and it never changes the order of anything below it.

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.
