Figuring out how much LSD you're actually dosing is the hard part. Unless you have loads from the same place and if you don't know them very well, the same batch. Or you're the one making it. Also if the first amount in your reduced dose doesn't make you trip like you wanted to, there's no guarantee that taking more will get you to where you want to be. I've tried it before with some mixed effects, and all the doses were from the same 3 ml of liquid I had. I've had a couple of little experiments but I will say I have absolutely no idea how it works in terms of multiple dosages after tripping. I tried it out of curiosity and learned not much, it varied from a no effect to me tripping harder than i wanted to initially.
So my answer to your question is, I don't have a clue.
Did that help? :D
