What quality standards do you follow?

We source high-quality research peptides manufactured under strict quality standards. Many products are accompanied by batch-specific testing documentation, including Certificates of Analysis (COAs) and HPLC purity reports where available.

What is a Certificate of Analysis (COA)?

A Certificate of Analysis (COA) is a laboratory document that provides information about the identity, purity, and quality of a peptide batch. It helps researchers verify that the product meets the specified quality standards.

What does HPLC purity mean?

High-Performance Liquid Chromatography (HPLC) is an analytical testing method used to determine peptide purity. A higher purity percentage indicates a lower presence of impurities within the sample.

How should research peptides be stored?

Storage requirements vary depending on the peptide. In general:

  • Lyophilised peptides should typically be stored refrigerated or frozen.
  • Reconstituted peptides generally require refrigeration.
  • Avoid repeated freeze-thaw cycles.
  • Protect peptides from excessive heat, moisture, and direct sunlight.

Always refer to the storage recommendations provided with each product.
