GCMS Results

There are very few independent essential oil chemistry experts and associated labs in the world and they generally have extremely tough schedules and offer very expensive testing services.

We were able to coordinate with two of the top experts and labs in the industry to have our most popular oils GCMS verified as pure and unadulterated.

Above are the results of comprehensive gc/ms testing for our top five oils by two different experts and labs. Primarily due to time constraints and scheduling on the part of the labs we were able to over the course of several months run all of our top 15 through one of the labs, and these tests can be seen below.
