I've been storing mazatapec. Vac sealed in a duffle bag and some not vac sealed in a duffle bag. Even the un-vac sealed have been holding their potency. It seems to me the biggest factors are heat and exposure to oxygen. Vac sealed is ideal, but even being stored in a bag that isn't being handled or opened mor than once a year seems to be agreeable.

And anything thrown into the freezer seems to just last.

When I was younger a guy stored them in a briefcase in Vancouver, broken down into grams, and those lost all their potency fast.

All my experienice is anecdotal, but it's served me well over 35 years of dealing with the things: dry, cool, no air flow.

I'll double down on the need for a vacuum sealer after your comments. I forgot that the enemy of just about everything is oxidation. While I have no idea how oxygen effects shrooms, I speculate that it can't be good in many cases.

But yeah, anecdotally, my mason jars have been just fine too. Each strain I have is a unique experience and does slightly change over time. While a mason jar isn't as effective as vacuum sealing for "perfect" storage, I suspect that oxidation (or just age) may alter the other psychedelic compounds found in the mushrooms a little more aggressively. (Just speculation though.)
