Once, only once, I was able to acquire some Sandoz acid straight from Switzerland. My source later proved to be a CIA operative trying to penetrate our bunch of Christian-pacifist draft resisters.

The difference from run-of-the-mill street acid was immense and indescribable. (Well, of course, everything about any LSD experience is basically indescribably ~ this is one case where the old phrase "you had to be there" is truly applicable.)

I was later privileged to sample some Owsley product, which was indeed quite excellent, but the pure Sandoz was absolutley incomprable. RIP Dr Hoffmann.
