COA Library: Rebuilding from Scratch

We only publish COAs we own. Every certificate in this library will be commissioned by us, for our stock, tested at a credible US-based laboratory before anything ships.

New inventory arrives in June. The COA library goes live at the same time. If you are on the waitlist, you will get the link before anyone else.

What Each COA Will Include

Third-Party Tested, Batch-Specific, Publicly Accessible

Every COA published here is tied to a specific batch ID. No summary numbers without the data behind them. No login required to view documentation.

  • HPLC Purity Report — chromatogram and percentage purity, not just a number
  • LC-MS Identity Confirmation — mass spectrum confirming the compound is what it says it is
  • Endotoxin Testing — LAL assay results in EU/mg
  • Batch Traceability — every vial linked to a single lot record, permanently on file
Library Status

New stock and COAs are expected in June 2026. This page will be updated at launch. If you have a specific compound you are sourcing for research, reach out directly and we can confirm availability and timing.
