Lab Test Results

Every batch of Peptology peptides is tested by an independent, certified laboratory before it is sold. Here you will find all the certificates of analysis (CoA) we have received, sorted by product, vial content and batch number.

What is tested in every batch

• Purity (HPLC): high-performance liquid chromatography measures the share of pure peptide in the sample. Our peptides have a purity of over 99%.
• Identity of the molecule (MS): mass spectrometry confirms that the molecule in the vial really is the peptide named on the label.
• Endotoxins (LAL): for selected batches we also test the content of bacterial endotoxins.

How to read a certificate

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