Quarterly market availability warning from KCA:
We have yet to analyze a 11-hydroxy-THC sample from the market that actually contains 11-hydroxy-THC. Materials labeled as such are typically low purity D8 distillates. Scanning QR codes from packaging shows a variety of unsatisfying results, including hits for the same 9B-hydroxy-HHC COA being passed around the industry.
We test for many cannabinoids and their metabolites in a variety of matrices, including 11-hydroxy-THC and 9B-hydroxy-HHC.
Don’t get suckered into buying materials without having them tested yourself.
