Alexander T. Shulgin
PIHKAL and TIHKAL
These two volumes document the Shulgins' groundbreaking research into psychoactive compounds. They combine scientific exploration with personal narratives, offering a unique look at the chemistry and effects of various substances.
PIHKAL is an acronym for "Phenethylamines I Have Known And Loved," and TIHKAL stands for "Tryptamines I Have Known And Loved." These titles reflect the chemical classes of compounds discussed in each respective volume.
The books blend scientific information, including detailed synthesis instructions and pharmacological data for various psychoactive compounds, with personal memoirs and philosophical reflections by the authors. They are unique for their combination of rigorous chemistry and autobiographical elements.
While they are distinct volumes, PIHKAL was published first and focuses on phenethylamines, while TIHKAL followed and covers tryptamines. Reading them in this order provides a chronological progression through the Shulgins' work and experiences.
