1. Guaranteed ≥99% HPLC Purity

Every batch of peptide sequence distributed by Onyx Peptides undergoes High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) analysis. We enforce a minimum purity threshold of 99.0%, ensuring that sequence contaminants, truncated fragments, and synthesis leftovers never distort your experimental data.

2. Full Analytical Transparency & Public COA Library

We remove all guesswork from raw material procurement. Every vial shipped from our distribution center features a lot-specific tracking code that links directly to our online Certificate of Analysis (COA) Library. Researchers can verify purity graphs, sequence mass verification, and sterility markers prior to reconstituting any compound.

3. Advanced Lyophilization & Cold-Chain Logistics

Synthetic peptides are sensitive molecular structures prone to degradation through temperature fluctuations and ambient moisture. Onyx Peptides utilizes state-of-the-art freeze-drying (lyophilization) protocols, sealing our research peptides under vacuum inert gas in climate-monitored environments to preserve maximum bioactivity throughout transport.
