Certificates of Analysis (COAs)

Certificates of Analysis are important to the understanding of the quality of the Hemp products you purchase. This testing, done by a third-party analytical laboratory, informs you of the concentration of each of the cannabinoids in the finished product.

Colorado has now implemented the requirement to test for microbes in any finished Hemp product. Future testing will include this information on the COA for each product. More info on testing is at the bottom of this page.

Some companies have their own testing facility and can thus manipulate the data. Mesa lavender farms sends a sample of the finished product to a private certified lab for testing to avoid any possible appearance of impropriety. The Certificates of Analysis resulting are considered “official documents”.

In addition to testing our finished products, Mesa Lavender Farms send samples of the concentrates we use (full-spectrum and Hemp isolate) to a third-party lab to confirm the concentrates we use are what the supplier’s documentation says it contains. It is not unusual to find a difference of 2 to 3 percent from what the distributor claims.

It is important for us to know the starting concentration of the products used to formulate our products so we can provide you, our customers, with salves, tinctures, lotions, and other products containing what the labels say they contain.

It normally takes at least a week once samples are sent to the lab to obtain the results of the COA. Those results are posted here to allow our customers to check the quality of the products themselves.

The State of Colorado now requires a batch number be placed on each Hemp product produced. That  number is affixed to the underside (bottom) of the product allowing you to locate the COA for that specific product. For example, if you have a Lavender Full spectrum tincture with a number on the bottom of the bottle, locate the lavender full spectrum tincture below and match the number on your product to the COA.

Hemp Isolate non-THC

The COA on the Hemp Isolate we are using  is at https://mesalavender.com/wp-content/uploads/2023/05/cbd-isolate-KND23-395.pdf . It shows 100% Hemp and no other cannabinoids are detectable.


The CoA on the distillate we use for our full-spectrum tinctures contains 0.21 % THC. Colorado does not allow the sale of products containing more than 0.3% THC. By the time the distillate is diluted to produce our fine products, the THC content is too low to detect. This distillate contains detectable levels of other cannabinoids to include Hemp, CBG, HempV, and CBC.

Certificates of Analysis: Microbial Testing

Colorado’s Department of Public Health and Environment now requires tests for the human pathogens Salmonella, Shiga-toxin producing Escherichia coli (STEC) Bacteria, coliforms, an aerobic plate count, and a test for yeast and mold for all Hemp products. Click on the associated link for more info.
