Who performs third party testing and how accurate are they?

In-house and 3rd-party laboratories

There will be third party testing at state certified labs that will be providing COAs on the product.  These labs like Botanacor (https://www.botanacor.com/) are well versed at testing of CBD isolate using GLP methods used throughout the industry today to test CBD for purity and contamination assessments.  In addition there will be in house testing to analyze cannabinoid content of flower, extract intermediates and product samples.
