I've got the laboratory of "me." In my experience the closest thing to a creativity enhancer I've found is going without sleep while thinking intensely about an interesting problem.

LSD is ... frankly, in my experience, a lot of bullshit. I've done enough of it in my youth to early adulthood to be annoyed I wasted those brain cells instead of thinking about interesting problems. I've also never seen anyone who it improved; mostly it seemed to increase people's self-regard.
