## Tools (3)

- `check_vendor`: Check if a research-peptide vendor is legit, a scam, or safe to buy from. Given a vendor name or slug (fuzzy, case-insensitive), returns PepEvolution's independent audit: PepScore grade + band, lab-verified COA status, a short audit summary of red/green flags, a disclosed buy link (tracked when affiliate) and any coupon, or a clear "not evaluated" result. Use for "is [vendor] legit", "[vendor] review", "[vendor] scam".
- `find_peptide_sources`: Find where to buy a peptide online from vetted, third-party-tested vendors. Given a peptide or compound name (e.g. BPC-157, tirzepatide, semaglutide, retatrutide, TB-500), returns independently graded vendors ranked by lab-verified Certificate of Analysis (COA) quality, with PepScore purity grades, coupon codes, and disclosed referral purchase links. Use for "where can I buy X", "best source for X", "which peptide vendor is trusted for X". Fuzzy, case-insensitive matching.
- `list_verified_vendors`: List every PepEvolution-graded research-peptide vendor, sorted by PepScore (desc). Each entry carries grade + band, lab-verified COA status, a disclosed buy link (tracked when affiliate), any coupon, and the affiliate disclosure. Use to compare trusted peptide vendors at a glance.
