What should I look for in a peptide vendor (quick checklist)?

Common trust signals researchers look for include:

  • Third-party COAs (HPLC/MS)
  • Lot/batch identifiers
  • Transparent contact information
  • Consistent history and reviews
  • Clear policies (shipping/returns)

No single signal guarantees quality, but transparency improves confidence.
