We take saftey and purity very seriously. To ensure all of our supplements are pure and their contents match their claims we send samples to a third party lab here in Germany - The BAV Institut. We also ensure that a COA (Certificate of Analysis) is provided by our suppliers before bringing a supplement online.
You can find each of the purity analysis reports from the BAV Institute on the product page for the supplement in question. Simply browse through the image gallery the certificate is displayed usually in the 4th or 5th position of the image gallery. If you cannot find a certificate of purity please feel free to contact us and we'll provide the documentation to you directly.
