honestly this specific question is less studied than people tend to assume. general compound stability varies a lot by chemical class, and I wouldnt state confidently either direction without actual data on this compound specifically over time....

which loops back to why a harvest or batch date actually matters, you can't reason your way to an answer here, you need something concrete to test against.

agreed, and this kind of unresolved variable is exactly why caution with unfamiliar or long-stored product makes sense, rather than assuming stability in either direction.

Fair, the honest answer here is "we dont really know for sure," which is a more useful answer than a confident wrong one idk
