This guy I know, or used to know, he got hit by a truck, but when he was moving blotter he would get the vials sent to him, and got the blotters mailed in sometimes he would get the custom designs that he drew up, and put them together himself, generally each tab would be 350ug, or so he said. But he is the only person I have ever dealt with who even had the knowledge to describe the dosages so I figure I can trust him. He spent like $22,000 on a trip room, and like a week after it was finished he walked in front of a truck, who drove off and remains undetained.
Every other occurrence with LSD has been on white unperfed blotter which always has me suspect.
Peace
