Every Certificate of Analysis we've ingested from zlzpeptide.com, what each tests for, and what's missing. Sourced back to the original COA URLs — no hosting, no editorial.
Each row is one peptide. Columns show whether at least one COA from this vendor for that peptide tests for that property. Endotoxin and sterility are usually the gap.
| Peptide | COAs | Avg purity | HPLC | MS/MALDI | NMR | Endotoxin | Sterility | Metals | Microbial |

Most recent batches we've ingested. Each row links to the original COA file as published by the vendor.
How this is built: we discover every COA URL on the vendor's public testing page, fetch the file, run structured extraction, and persist what each COA actually tests for. Vendor copy isn't a signal — only the COAs themselves.
