Testing & Certificates of Analysis
Every batch is independently verified before it reaches our catalog.
Third-party analysis
Each lot is assayed by an independent laboratory using HPLC for purity and mass spectrometry for identity. We publish the resulting Certificate of Analysis (COA) on the relevant product page and provide it on request.
What we measure
Purity (target ≥99%), peptide identity, and net peptide content. Lots that do not meet specification are rejected.
Handling & storage
Products are lyophilized and shipped with discreet, temperature-aware packaging. Store as indicated on the product page to preserve integrity for laboratory work.
