Every peptide batch we source undergoes independent third-party analysis through Janošik Laboratories, one of Europe’s most respected analytical testing facilities. Janošik specializes in high-precision peptide assessment and is recognized for its strict methodology, advanced instrumentation, and uncompromising accuracy standards.

Using state of the art techniques such as HPLC, mass spectrometry, and purity verification, Janošik’s scientists confirm that each peptide matches its labeled identity, potency, and specification. These tests ensure that our products consistently reach research-grade purity levels greater than 99.1%, giving investigators full confidence in the materials they are working with.

All Certificates of Analysis (COAs) are generated directly by Janošik and published for complete transparency.
