• find_peptide_sources read-only

  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.

  Parameters:

  • compound (required) — string — Compound name or slug, e.g. "BPC-157", "tirzepatide"

  Hints: read-only yes · destructive not declared · idempotent yes · open-world no

• check_vendor read-only

  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".

  Parameters:

  • name (required) — string — Vendor name or slug, e.g. "Peptide Plugs", "biolongevity-labs"

  Hints: read-only yes · destructive not declared · idempotent yes · open-world no

• list_verified_vendors read-only

  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.
