Before leaving our facility every batch of our supplements completes rigorous testing to ensure quality. Chemical analyses are completed to ensure that each batch contains the exact quantities of material listed on the label for each of our products. This analysis also ensures that our supplements are free of unwanted contaminants. We are proud of the quality we build into each of our products and that is why a certificate of analysis is provided for each material we manufacture. Our products are backed by science to ensure that you get the results you want.
