TeamHow do you actually verify a COA is real?

The checks we run on every COA before it counts toward a vendor's testing score: 1. Batch match. The COA must state a batch/lot number, and the vendor must show which batches are on sale. A generic COA with no lot number proves nothing about your vial. 2. Named, real lab. Janoshik, Kovera Labs, IS-Lab and similar publish verification: Janoshik has an online report-verification tool, and accredited labs list their accreditation number (e.g. IS-Lab is ISO/IEC 17025 accredited, PJLA #80565). Search the lab, confirm the report format matches, use the verification portal when one exists. 3. Recent date. A 2023 COA on a 2026 batch is decoration. 4. The right tests. Purity (HPLC) alone isn't enough — you want net content (is there actually 10mg in the vial?) and mass-spec identification at minimum. Sterility, endotoxin, and heavy-metal panels are the tier above. 5. Consistency. One good COA can be borrowed or faked. Dozens of downloadable batch-specific COAs over time is a pattern that's hard to fake — Ascension Peptides has 77 on file, for example. If a vendor won't show a batch-specific COA on request, that's your answer. Our per-vendor scoring is at peptidepub.com/vendors and the method is at peptidepub.com/methodology.
