how long can acid last?

yes i am aware about lsd degradation from heat, light & oxygen but i was wondering if you were saving a blotter for a while where would be the best place to store it with the least degradation?

cheers in advanced

freezer

^^...in an airtight container (like a vitamin jar) preferably in a baggie and have silica gel in the container to keep it it dry.

on removal from the freezer allow it to get to room temprature before opening otherwise condensation might undo all your good work.

Heaps of threads on this i'm sure. just search.

Search first, ask second...

LSD storage and purity/potency issues.
