Our approach

How we verify every batch

Every compound is characterized before it ships. We test identity and purity by HPLC and mass spectrometry, and issue a batch-specific Certificate of Analysis you can download.

Raw material sourcing

We source from qualified peptide manufacturers and synthesis labs, not repackagers.

Independent HPLC testing

A third-party lab verifies purity by high-performance liquid chromatography, with a minimum threshold of 99%.

Mass spectrometry ID confirmation

Mass spectrometry confirms the peptide’s molecular identity matches what’s on the label.

Certificate of Analysis (COA)

Every batch ships with a COA you can view on the product page or request by lot number.
