i seems lsd has become scarce now its all e and other mind numbing crap. yeah take good care of that i always used the freezer w tweezers not in 10 years though.
Just put it in your dresser drawer. The freezer has too much moisture and the tin foil will produce condensation when you finally take it out of the freezer.
LSD should be stored in a cool, dark, dry, place. Have fun, I know I will, lol. I plan on going camping with my white blotters!
if the container is sealed and no moisture is going in or out they should last along time i use to replace them every six months for good measure with fresh silica packs from newly oppened vitamin bottles.
Honestly I would keep liquid in the freezer even in those plastic foodcolouring vials, and they would stay good for at least 6 months.. no special procedure.. just cap on tight...
