Quality Assurance

Rigorous Testing. Verified Purity.

Every batch of every product is tested by ISO 17025 accredited laboratories before it reaches your lab. We employ multiple analytical methods to verify identity, purity, and safety — and document everything in a batch-specific Certificate of Analysis.

Testing Methods

HPLC Purity Analysis

High-Performance Liquid Chromatography confirms the purity of every batch. We require ≥99% purity for all peptide products. Results are documented on the batch-specific Certificate of Analysis included with your order.

Mass Spectrometry (MS)

Mass spectrometry verification confirms the molecular identity and weight of each compound. This ensures the product matches its theoretical molecular weight within acceptable tolerance — you receive exactly what's on the label.

Documentation

Certificate of Analysis (COA)

Every order includes a batch-specific Certificate of Analysis documenting all testing results. COAs provide complete transparency into the quality of every product you receive.
