Laboratory analyses

Every batch of Peptology peptides is tested by an independent, certified laboratory before it is placed on the market. Here you will find all the Certificates of Analysis we have received, organised by product, vial strength and batch number.

What is tested in every batch

• Purity (HPLC): high-performance liquid chromatography measures the percentage of pure peptide in the sample. Our peptides have purity above 99%.
• Molecule identity (MS): mass spectrometry confirms that the molecule in the vial is indeed the peptide stated on the label.
• Endotoxins (LAL): in selected batches we also test the level of bacterial endotoxins.

How to read a certificate

Search for the product and strength you are interested in and compare the batch number with the one on your vial. Each certificate opens as a PDF with the date of analysis, the method and the result. The products are intended exclusively for laboratory research.
