COA means Certificate of Analysis. Obtaining a COA means that we contract with a lab (that is not us) to test and scrutinize our product to ensure that what we say about our products is in fact, true.
All vtbio products are 3rd party tested at the harvest level (non-diluted cannabidiol) and again at the final, post-dilution level, by product, to confirm THC (<.3%) and cannabinoid content. In addition we use the testing process to confirm our math with regard to CBD concentration and dilution protocols, as well as seasonal harvest planning.
