Every batch has its own third-party COA, published before you buy

At Prime Peptide Solutions, every batch we sell is tested by independent, ISO/IEC 17025-accredited labs (ILS Labs and Kovera Labs). Each Certificate of Analysis covers one batch and one size, with HPLC purity and mass spectrometry identity results.

All COAs are public, with no account needed, so you can read them and check the lab's report number before you order. A batch that does not pass testing is never listed for sale.
