There has been a lot of speculation and controversy about purity of some oils. The KZ85 has been a hot potato for a while. I have never tried this oil but it certainly has a following.
There have been claims by some the oil is pure and others that it may not be. So recently, the GCMS result for this oil was posted on Basenotes.

The comments from the tester state "The sample did contain some authentic agarwood essential oil but the sample was also cut with a significant amount of non-volatile material as evidenced by the low TIC number, the unusual late eluting components and the combination with phthalates."
So, unless my reading comprehension is going bad, it appears the questions about it being a pure oud seem to be valid?
