Third-Party Lab Testing
Every batch of peptides we sell is sent to Janoshik Analytical, an independent third-party testing laboratory, for mass spectrometry and purity analysis. Each Certificate of Analysis (COA) confirms the identity and purity of the compound in that batch, and COAs for our tested products are posted on the corresponding product pages. Results can also be independently verified using the unique key printed on each report at janoshik.com/verify.
