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.
All 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.
Sasha & Ann have been in serious financial trouble for some years, and the coming medical bills will be a burden they can’t bear alone. Please, express your gratitude for all the work that Sasha has done, for everything he has given to the world, and give something back.
