Independent verification.
Every lot, every time.

We do not release any compound that has not cleared third-party analytical testing. Certificates of Analysis are available for every lot number in our searchable library.

  • HPLC-UV at 218nm — every production batch, minimum threshold 99.0%.
  • Mass spectrometry (LC-MS) confirms molecular identity before any lot ships.
  • PeptideMeter and Freedom Diagnostics issue all COAs — not Fraction Research. Independent by design.

All COA documents are publicly searchable by lot number. Enter any lot number from your shipment to retrieve the full analytical report.
