What is the correct way to preserve lsd for a long period of time, also if preserved in the correct manner how long could lsd last?
There are debates on what is necessary. Some say it does fine at room temperature (and I know for a fact that it does, for at least a month or two). A lot of people put it in the fridge. LSD is extremely fragile, and basically anything is going to degrade it, including air, light, and especially serious heat. I would tear off a big sheet of tin foil , way bigger than the doses, and TIGHTLY seal the doses inside the tin foil. If you have an air-tight glass bottle, put the foil/doses in there and then put it in the freezer or fridge. If not, throw it in a ziplock or two, just to make sure a bunch of water vapor etc. doesn't sneak in (would this matter? probably not, but better safe than sorry). Your LSD should be safe for as long as you would ever wait to trip. Many months, years, etc.
