I read the related threads at the Lycaeum and a Trip report at Erowid where it was told that piracetam intensivies the effects of LSD. I tried it and its true.
It also smoothens the comedown after my experience, very nice.
How this compares to something else I dont know, I take Piracetam for other reasons and thats why I looked it up. Good acid has no need to to be mixed with anything else - thats how I feel about this and I am no human guinea pig.
I will post the links later when I find them, Lyzaeum´s search engine doesnt love me at the moment
EDIT: found it! HERE
