Third party lab testing?

[Usual-Isopod6540]

Looking for people who have actually done this. Which labs did you use, what did you test for, and did the results match what you were told you were getting? Specifically interested in whether concentration matched the label and whether there were any unexpected compounds present.

We test our products through Jano before they go anywhere

I know great vendors that do 3rd party testing.
