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 medicines, 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 skeleton

All phenethylamines on this website are drawn with the ring locants arranged clockwise, as drawn at left. This is sometimes at odds with the practice followed in PiHKAL
