I would leave it as liquid, personally. If you lay it on blotter, you're gonna lose some, and a vial isn't enough to not worry about it.
If it's for personal use leave it liquid. Keep in dark, cool place with minimum exposure to air and it could last a long time. Blotter is actually one of the worst ways to store lsd if your want to preserve quality. On blotter more lsd is exposed to air and light. Liquid free from light and air is the best, Then pill forms, especially if coated with a light and air tight coating. Then blotter. Blotter is popular because it is the easiest, cheapest form for the distibuter and end user to handle. But blotter is by far one of the worst storage mediums.
SWIM blah blah blah blah, no one is tracking you down on here and if they are you look quite silly saying SWIM!!
Liquid is totally the best medium to store LSD in. Archaeologists actually just uncovered a vial of LSD from the tomb of an Egyptian pharaoh. Its still potent.
So there is no truth to laying it down on blotter, allowing the alcohol to dry and the lsd to re-crystalize on the paper, allowing it to last longer? I might actually do 50/50 and test this Oh and surely blotter would be better than sugar cubes in that less air would be able to get at it to degrade it (1 cubic cm of air in the cube for example vs tiny amounts in blotter in plastic inside a book..?)
I would go with the fridge over the freezer. The last thing you want is freezerburnt LSD. I know it's unlikely with liquid, but it can happen.
I'm not a fan of blotter. Do you have a tableting machine? Leave it in the vial and put it in the fridge I agree.. If you found one of those 40 year old Orange sunshine or Blue Cheer tablets it would still work perfectly...blotter from last year would be suspect.
