From synthesis to your inbox.
Every batch passes a three-step independent verification before it ships. Tests are performed by accredited third-party laboratories: Janoshik Analytical, Krause Analytical and Chromate Analytics, using HPLC and mass spectrometry. The full Certificate of Analysis is published on every product page.
Step 01
HPLC Purity
High-Performance Liquid Chromatography quantifies the active peptide content. Reported to 0.1 percent. Failures below 98% are rejected.
Step 02
Mass Spectrometry
Molecular weight verification confirms the compound's identity matches the declared sequence. Catches misidentified or substituted material.
Step 03
Independent Lab
Both tests are performed by accredited third-party laboratories. Janoshik, Krause Analytical, Chromate Analytics. Certificates published.
