Frequently asked

Is PeptideBase selling peptides?

No. We don't sell compounds, we don't ship anything. We're a research database and clinic/vendor directory. All referrals are to licensed clinics or lab-tested research vendors.

What does the AI chat actually use?

Claude Sonnet with RAG — retrieval over our own database of 2,000+ peer-reviewed PubMed citations, FDA label data, ClinicalTrials.gov studies, and regulatory event records stored in Neon pgvector. Every factual claim in a response is cited to a specific PMID or record.

Why not just use ChatGPT?

ChatGPT answers from its training data, which freezes at its cutoff. Peptide regulations, FDA compounding categories, and new trial readouts change constantly. PeptideBase pulls directly from fda.gov, federalregister.gov, and ClinicalTrials.gov so the answers stay current.

Can I cancel Pro anytime?

Yes — monthly or annual, cancel any time via the Stripe customer portal. No cancellation fees.

Do clinics pay for rankings?

Featured listings are paid. Our ranking signals (evidence grade, verified COA count, clinic credentials, community reviews) are editorial and not for sale.

What does "Grade C" mean for a compound?

Animal studies only. No completed human trials. Mechanism may be plausible but translation is unproven. We're conservative on purpose — we'd rather say "we don't know" than fake confidence.
