I think LSD is strange and great i had my most uncounscious trip with it (i took 3500ug from the cleanest amsterdam LSD ever) i was in an other world i barely remember what happened in real i understood the universe, but you have drugs such as 2CE or DOI, DOC that can bring you way more visual hallucination. You say that 500 to 800ug is a 8 hours trip but dude LSD-25 and either his cousin PRO-LAD, ALD-52, ETH-LAD and 1P-LSD are active at 25ug, a medium trip is 70ug and strong trip is 100 to 150ug for 12h triping balls depend on the person, but i dont think the dealer who sell you 800ug LSD dose is selling you LSD, because 800ug would still be for a regular consumer a massive dose that would make him trip for more than 24h. 25i-NBOM is active and sold from 800ug to 1500ug generally and is not from lysergic family but from 2CX family and so it have nothing in comon with LSD. Lsd is mostly sold liquid in small dropper or in blotter form, the blotter and drops contains in average 70ug to 150ug max. If its its pills you have strong chance that your lsd is 2CE mixed with a bit DOB. If you want to detect false LSD you just have to use a black lamp LSD and family analogue will react and become flashing blue. You can find lsd in crystal but its very dangerous to hold as 1mg = 1000ug wich is consider to be 10 doses (strong) of LSD. And 2000ug of LSD is extremely dangerous to anyone who is not hardcore tripper as its like taking 20 strong trip of LSD it can be harmefull and bring you to hospital, may cause you psychose and you may hurt yourself but it will not be wastefull as lsd dont have High potency limit so more you take more you get high and you can rich K-All. And when you make your own acid there is no way to calculate the amount of LSD as it need 60% purity to become crystal and so potency can be 40% diffrent from a crystal to an other and only testing with mass spectrometre will tell you the purity wich is not a comon chemist tools :p. So be carefull and remember dark light show you instantly what is lsd or not
