PURITY & QUALITY
Purity & Quality Guarantee
Local biotech labs in USA and EU. No shortcuts on quality.
Local biotech laboratories in the USA and EU synthesize our peptides. We don’t cut corners on synthesis or testing to chase the lowest price. Working with domestic labs in both regions enables us to provide you the best quality control and fast logistics from our domestic warehouses.
Our manufacturing process uses advanced solid-phase peptide synthesis (SPPS) and optimized protocols for cleavage and purification. Each peptide batch undergoes internal analytical testing to assess purity, identity and consistency. We also use independent third-party laboratories to verify quality.
INTERNAL & INDEPENDENT TESTING
Tested internally. Checked & Verified Independently.
Internal testing is part of our quality-control process. Independent third-party analysis provides another additional check. Our analytical methods include HPLC and mass spectrometry.
