How long are Psilocybin Mushrooms good for?

Well, out of pure luck and randomness, I've stumbled upon the sacred mushrooms from a friend, and I'm at a great place in life to be taking them again, so I'm pretty excited.

But I'm not sure I'll be able to take them right away, and I was going to rent a cabin in the woods when I find the time to take them. I'm going deep.

Just curious-- is there any specific way to store them to make sure they don't go bad for a few weeks? How long until they go bad? Phone Post 3.0

Should last for years if stored in freezer.

Good to know, thanks guys. Phone Post 3.0

Me and a couple buddies had some old shrooms that we ate one night on a whim. Approximately 30 seconds after we came to the resolute conclusion that they had lost their potency, they kicked in. Pretty hard.

Good times.
