Here at CBD Pure, we believe in complete transparency when it comes to exactly what is in every bottle. Every batch of every product is tested 3 times, once at harvest, once at our production facility, and once by an independent third-party laboratory. Because we use all-natural, minimally processed CBD hemp oil, some natural variation will occur between every batch, as each crop is unique. Our test results are publicly available, for every batch going back 24 months. You can look up any batch below using the lot number found on the bottom of every bottle of CBD Pure.
