In 1991 and 1997, he and his wife Ann Shulgin compiled the books PiHKAL and TiHKAL (Phenethylamines I Have Known And Loved, likewise for Tryptamines), from notebooks that extensively described their work and personal experiences with these two classes of psychoactive drugs. Shulgin documented the chemical synthesis of many of these compounds. Some of the syntheses catalogued by Shulgin in his books include chemicals in the 2C family (such as 2C-B), compounds of the DOx family (such as DOM), and tryptamines (such as 4-HO-MET and 4-HO-MiPT).
