Murd0c's dead on with the availability, I've heard this for years for never checked this online... I've understood there were four 'national sources' until circa 2000-01 when all but one was shut down.
7-8 years ago I was at a guy's house that had nearly a 2-liter of liquid, ready to be dropped... ever since he got ripped off I haven't heard or seen the likes of Lysergia around here. The manmade LSD experience is way different than the right shroom... much harder to regulate, you can easily trip for days!
WTF is 5-MeO-AMT anyway? Isn't there a shorter name for it?
LSD sucks anyway (rly) - after a certain amount you are genuinely not in control of your emotions. Just stick to underage drinking.
