Every batch undergoes rigorous analytical testing, including High-Performance Liquid Chromatography (HPLC) for purity and Mass Spectrometry (MS) for sequence identity. A detailed Certificate of Analysis (COA) is provided with every shipment.

In-stock retail items are typically prepared within 2-3 business days. For Custom Synthesis, the production cycle is approximately 14 days, followed by global transit. We prioritize accuracy and structural integrity over speed to ensure research reliability.

For long-term stability, peptides should be stored in a lyophilized (powder) state at -20°C or -80°C, protected from light and moisture. Avoid frequent freeze-thaw cycles once reconstituted.
