None. Unless your are licensed. Which is a huge fucking hassle. And then you might as well be running 10s or 100s of samples because it aint cheap for a handful of pulls.
No lab will run a sample for you unless dea approves. Not many companies or growers licensed are able to do an adequate R and D, because the margins are thinner than a restaurant in general.
Now if you could go a route like Jodrey and run an in house gc, than your in business. You have to look at what they are using for standards as well.....aka we dont even have a standardized set of terpeniods applicable to the plant....
It could be a useful tool, but even if we start to understand it, it will never be a stand alone tool, or shouldnt be.
I wouldnt use Phylos either.
Edit: Im intentionally vague because things change but these labs are ideally setup to test the bare minimum and not for in depth testing. If I wanted to test for a PUP [plant utility patent], then the commercial process would be more suitable.
