PiHKAL: A Chemical Love Story is a book by Dr. 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 empathogen-entactogens. The main title, PiHKAL, is an acronym that stands for "Phenethylamines I Have Known And Loved".
2C-T-7 is a psychedelic phenethylamine of the 2C family. In his book PiHKAL: A Chemical Love Story, Alexander Shulgin lists the dosage range as 10 to 30 mg. 2C-T-7 is generally taken orally, and produces psychedelic and entactogenic effects that last 8 to 15 hours. Up until Operation Web Tryp and three deaths, two of which involved the use of other drugs in addition to 2C-T-7, and one which involved an excessive insufflated dose, 2C-T-7 was sold commercially in Dutch and Japanese smartshops and online. It is known on the streets as Blue Mystic or 7th Heaven. There has been little real research done on this chemical other than Shulgin's comments in PiHKAL and a few small animal studies mostly aimed at detecting metabolites.
2C-E is a psychedelic phenethylamine of the 2C family. It was first synthesized by Alexander Shulgin and documented in his book PiHKAL. Like the other substances in its family, it produces sensory and cognitive effects broadly similar to those of LSD and mescaline. It is also a powerful vasoconstrictor at high doses.
2C-T-21 is a psychedelic phenethylamine of the 2C family sometimes used as an entheogen. It was first synthesized by Alexander Shulgin.
2C-T-8 is a psychedelic phenethylamine of the 2C family. It was first synthesized by Alexander Shulgin, sometimes used as an entheogen.
Escaline (3,5-methoxy-4-ethoxyphenethylamine) is a psychedelic drug and entheogen of the phenethylamine class of compounds. Escaline was first synthesized and reported in the scientific literature by Benington, et al., in 1954, but was later re-examined in the laboratory of David E. Nichols, who prepared a series of mescaline analogues that included escaline, proscaline, and isoproscaline. The effects of this and related mescaline analogues in humans were first described by Alexander Shulgin. In his book PiHKAL , Shulgin lists the dosage range as 40 to 60 mg, consumed orally. The duration of action was stated to be 8–12 hours.
2C-T-4 (2,5-dimethoxy-4-isopropylthiophenethylamine) is a psychedelic phenethylamine of the 2C family. It was first synthesized by Alexander Shulgin and is used as entheogenic recreational drug.
Proscaline (4-propoxy-3,5-DMPEA) is a psychedelic and hallucinogenic drug. It has structural properties similar to the drugs mescaline, isoproscaline, and escaline. In PiHKAL, Alexander Shulgin reports that a dose of 30–60 mg produces effects lasting 8–12 hours.
2C-TFM is a psychedelic phenethylamine of the 2C family. It was first synthesized in the laboratory of David E. Nichols. It has also been called 2C-CF3, a name derived from the Para-trifluoromethyl group it contains.
2,4,5-Trimethoxyphenethylamine or is a phenethylamine of the 2C family and was first synthesized by Jansen in 1931. It is a positional isomer of the drug mescaline (3,4,5-trimethoxy).
2C-O-4 (4-isopropoxy-2,5-dimethoxyphenethylamine) is a phenethylamine of the 2C family. It is also a positional isomer of isoproscaline and was probably first synthesized by Alexander Shulgin. It produces hallucinogenic, psychedelic, and entheogenic effects. Because of the low potency of 2C-O-4, and the inactivity of 2C-O, Shulgin felt that the 2C-O series would not be an exciting area for research, and did not pursue any further analogues.
Isoproscaline or 4-isopropoxy-3,5-dimethoxyphenethylamine is an analog of mescaline. It is closely related to proscaline and was first synthesized by David E. Nichols. It produces hallucinogenic, psychedelic, and entheogenic effects.
4-Desoxymescaline, or 4-methyl-3,5-dimethoxyphenethylamine, is a mescaline analogue related to other psychedelic phenethylamines. It is commonly referred to as DESOXY. DESOXY was discovered by Alexander Shulgin and published in his book PiHKAL.
Aleph is a psychedelic hallucinogenic drug and a substituted amphetamine of the phenethylamine class of compounds, which can be used as an entheogen. It was first synthesized by Alexander Shulgin. In his book PiHKAL, Shulgin lists the dosage range as 5–10 mg. According to Shulgin, the effects of aleph typically last for 6 to 8 hours.
2C-T-13 is a psychedelic phenethylamine of the 2C family. It was presumably first synthesized by Alexander Shulgin and reported in his book PiHKAL.
2C-T-15 or 2,5-dimethoxy-4-(β-cyclopropylthio)phenethylamine is a psychedelic phenethylamine of the 2C family. It was presumably first synthesized by Alexander Shulgin and reported in his book PiHKAL .
2C-T-17 or 2,5-dimethoxy-4-(β-secbutylthio)phenethylamine is a psychedelic phenethylamine of the 2C family. It was presumably first synthesized by Alexander Shulgin and reported in his book PiHKAL .
3,4-Methylenedioxy-N-propylamphetamine is a lesser-known psychedelic drug and a substituted amphetamine. MDPR was first synthesized by Alexander Shulgin. In his book PiHKAL, the minimum dosage is listed as 200 mg, and the duration unknown. MDPR is a promoter; by itself it has almost no effects on the mind, but it promotes the effects of hallucinogens, similarly to the closely related MDPH.
Phenescaline, or 3,5-dimethoxy-4-phenethoxyphenethylamine, is a lesser-known psychedelic drug. It is an analog of mescaline. Phenescaline was first synthesized by Alexander Shulgin. In his book PiHKAL , the minimum dosage is listed as 150 mg, and the duration is unknown. Phenescaline produces a threshold effect. Very little data exists about the pharmacological properties, metabolism, and toxicity of phenescaline.
2C-Se is a lesser-known psychedelic drug. It was originally named by Alexander Shulgin as described in his book PiHKAL. Shulgin considered 2C-Se to be around three times the potency of mescaline, but was too concerned about toxicity to test it extensively, though he considered it noteworthy as the only psychedelic drug to contain a selenium atom.
