The bottle says each pill is 850 mg which would make 40-45% about 400 mg. Very high.

You can go to the website and see all results.
This is what they said about my sample:
“Your sample (expected as Umary) tested as microcrystalline cellulose (pill filler) 45-50%, diclofenac 40-45%, and an uncertain oil (pill binder) 10-15% by FTIR spectrometer. It tested
negative for fentanyl or fentanyl analogs by test strip.”

This is inBC, Canada and it appears that these strips are used for testing there at government drug testing sites as well.
