Certificates of Analysis

Transparency first. Every compound we carry is third-party tested and documented — organized by product and batch, never a pile of random files. Confirm identity, purity, and molecular data before a vial is ever opened.

99%+

Purity Verified

Identity and purity confirmed by high-performance liquid chromatography (HPLC).

3rd

Party Tested

Independent laboratories verify every batch — not just our own quality control.

CoA

Per Batch

A Certificate of Analysis with mass-spec confirmation accompanies every batch.

How to Read & Verify a COA

Confirm the batch number +

Match the batch/lot number printed on your vial to the batch listed on its Certificate of Analysis. They should be identical.

Check the HPLC purity result +

The HPLC section reports measured purity. Our standard is ≥99%. The chromatogram should show a clean, dominant single peak.

Confirm identity via mass spectrometry +

Mass-spec data confirms the compound's molecular weight matches the expected value for that peptide — verifying you have the correct material.

Something doesn't match? +

If a batch number or result doesn't line up, we want to hear about it. Reach out and we'll resolve it quickly.
