So I live in Basel, Switzerland (place where LSD was discovered) and a dealer friend of mine says he has 1000ug lsd blotters and that if i want one i should only take a quarter tab. I dont think that theres LSD on them and i would think its something like 25i or something i dont know im not very experienced in psychedelics / research chemicals. Does LSD come in such high doses and if it is 25i should i only take a quarter or a half? So a 250ug dose or a 500ug? I havent done LSD or 25i before but am read to try either.
