Cover of PiHKAL: A Chemical Love Story, by Alexander & Ann Shulgin. Cover art by Pamela Engebretson PiHKAL • info is a visual index and map of “PiHKAL: A Chemical Love Story,” by Alexander & Ann Shulgin. PiHKAL is the extraordinary record of the authors’ years exploring the chemistry and transformative power of psychedelic drugs, and phenethylamines in particular.

PiHKAL (the book) covers a lot of ground. There are detailed reports on 179 substances, and mention of perhaps 150 more. Still other phenethylamines, not discussed in the book, are known or are suspected to have psychedelic potential. PiHKAL • info is my attempt to map out the terrain.

Numbering of the Phenethylamine skeletonAll phenethylamines on this website are drawn with the ring locants arranged clockwise, shown at left. This is sometimes at odds with the practice followed in PiHKAL.

Speaker’s Corner

“Sasha is a major catalyst that helped shape a generation of brilliant-minded people. Terence McKenna and Alan Watts always spoke highly of Sasha’s creations in their lectures, I believe that these three scholars will be remembered as key figures in forming a rational, more effective approach to the field of mental health & medicine.”

“The young people in this video are an example of a new generation that share the passion—that same passion that Sasha & Ann have. We stand on the shoulders of giants; Sasha is in a league of scientific achievement, right there with Newton, Einstein, & Hofmann.”
