COA Testing

Certificates of analysis and verification standards.

Every batch released through FlexMed is tested by an accredited third-party laboratory. Testing data is published batch-by-batch — not as a generic product sheet.

COA Testing Workflow

01
Batch submission
Each peptide batch is submitted to a third-party testing laboratory following production. No batch is released for fulfillment before testing is complete.
02
Third-party HPLC + MS analysis
Testing is conducted using High-Performance Liquid Chromatography (HPLC) for purity and Mass Spectrometry (MS) for identity confirmation and molecular weight verification.
03
CoA publication
Results are compiled into a Certificate of Analysis (CoA) and published on the relevant product page. The batch is marked as available only after the CoA is live.
04
Batch traceability
Each CoA is tied to a specific batch number. Researchers can verify the exact batch they are ordering against the published documentation.
