Testimonials

… what a great work! … You’re clearly a bit of a fanatic, in the best, Sasha-sense of that word. Like him, you’re an inveterate cataloger, accumulator and organizer of information, which is just what’s called for in this instance. …When people ask me what is the definitive reference on natural tryptamines, I now know what to tell them. … a most useful addition to my reference shelf!
