Hello hello, out of all curiosity i wanted to know if dmt starts degrading once in its acid solution and if so how slow ?

nope

Cheers for the quick reply~!

Has anyone ever done the acid boils of an A/B then canned the brew for long term storage?

I've been thinking this may be a discreet way to store bark.

Also it would be ready for base upon opening in the future.

Any thoughts or input?

Sure you could boil and then store. That´s basically what is done with ayahuasca.

Not sure about canning specifically because I´ve never done it, but from quick reading that link, I´d be wary of this whole ´lead and Bisphenol A´ migrating to the solution. I would do quite a few clean up steps later on to prevent any of those impurities from coming across, such as doing sodium carb washes on the solvent, precipitating with FASA/FASI, washing fumarates with acetone or IPA, etc...
