Peptide Certificates of Analysis

At Zybiopeps, product purity and research integrity are non-negotiable. Every peptide we carry is third-party tested to verify compound identity, concentration, and purity before it reaches our customers.

We are committed to full transparency in our testing process. Our products are independently analyzed using High Performance Liquid Chromatography (HPLC) — the gold standard method for peptide purity verification.

Current Batch Purity: 99%+

All Zybiopeps peptides meet a minimum purity threshold of 99% before being made available for research purchase.

Why Third Party Testing Matters

Third party testing means an independent laboratory — with no commercial interest in the result — verifies our compounds. This eliminates bias and gives researchers confidence that what is on the label matches what is in the vial.

At Zybiopeps we believe researchers deserve complete confidence in the compounds they work with. That commitment to quality is built into everything we do.
