The heavy metals results are relatively self-explanatory, as the results section shows the exact levels (to four decimal points) of the heavy metals we tested our finished products against. The HPLC test section can be more confusing to consumers who don't have a STEM background. This type of testing quantifies constituent compounds in the botanical. It proves the potency of the finished product, and of our standardization. Any specific questions about the HPLC results can be directed to our email: info@illuminatelabs.org
