The potency and purity of our products can be obtained by referring to the batch number on the label of each bottle of Gundry CBD products. Below are lab reports. Different strengths may have the same lab report. Lower strengths were derived from higher strengths. This was achieved by adding Organic MCT oil to the original batch strength. EXAMPLE: 500mg bottles with the same batch number as a 1000mg lab report are exactly (one half) of the values represented in that report. 250mg are (one quarter) of those same values.Please feel free to contact us with questions or requests for any additional lab reports.
