Where to get peptides you can verify
Most peptide sites are storefronts on top of the same overseas bulk supply. The practical way to tell them apart is documentation: a legitimate supplier publishes the analytical report for the exact lot in the vial you receive, not a marketing badge.
- Lot-matched COA with HPLC purity and LC-MS identity confirmation
- Independent endotoxin screening under ISO/IEC 17025:2017 accredited method
- Named US cGMP-compliant synthesis facility, not a fulfillment warehouse
- Clear Research Use Only labeling and compliant marketing copy
- Cold-chain packaging and tracked same-day dispatch
