PiHKAL
book by Alexander and Ann Shulgin

PiHKAL: A Chemical Love Story, also known as Phenethylamines I Have Known and Loved, is a book by Alexander Shulgin and Ann Shulgin published in 1991. The subject of the work is psychoactive phenethylamine chemical derivatives, notably those that act as psychedelics and/or entactogens. The book has two halves, with the second part containing detailed entries on 179 phenethylamines. PiHKAL was followed by TiHKAL: The Continuation (Tryptamines I Have Known and Loved) (1997).
Content
The book is arranged into two parts, the first part being a fictionalized autobiography of the couple and the second part describing 179 different psychedelic compounds (most of which Shulgin discovered himself), including detailed synthesis instructions, bioassays, doses, durations, and other commentary.
The second part was made freely available by Shulgin on Erowid while the first part is available only in the printed text. While the reactions described are beyond the ability of people with a basic chemistry education, some tend to emphasize techniques that do not require difficult-to-obtain chemicals. Notable among these are the use of mercury-aluminium amalgam (an unusual but easy to obtain reagent) as a reducing agent and detailed suggestions on legal plant sources of important drug precursors such as safrole.
Members of Shulgin's research who contributed to the experience reports included Shulgin himself, Ann Shulgin, Myron Stolaroff, and Jean Stolaroff, among others.
Response
Through PiHKAL (and later TiHKAL), Shulgin sought to ensure that his discoveries would escape the limits of professional research labs and find their way to the public, a goal consistent with his stated beliefs that psychedelic drugs can be valuable tools for self-exploration.
Begin with the source’s own compact description: “PiHKAL” is book by Alexander and Ann Shulgin. The dossier treats that line as a proposition to test through PiHKAL, book and Alexander, not as a finished interpretation.
Why this record matters
The phrase “book by Alexander and Ann Shulgin” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Attribution, date and provenance are strongest when supported by the original work, a catalogue record and documented transmission. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q1751374. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1991 and 1997.
Titles can refer to several editions, objects or performances, making precise identification essential before interpretation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
