Trimethoxyamphetamines (TMAs) are a family of isomeric psychedelic hallucinogenic drugs. There exist six different TMAs that differ only in the position of the three methoxy groups: TMA, TMA-2, TMA-3, TMA-4, TMA-5, and TMA-6. The TMAs are analogs of the phenethylamine cactus alkaloid mescaline. The TMAs are substituted amphetamines, however, their mechanism of action is more complex than that of the unsubstituted compound amphetamine, probably involving agonist activity on serotonin receptors such as the 5HT2A receptor in addition to the generalised dopamine receptor agonism typical of most amphetamines. This action on serotonergic receptors likely underlie the psychedelic effects of these compounds. It is reported that some TMAs elicit a range of emotions ranging from sadness to empathy and euphoria. TMA was first synthesized by Hey, in 1947. Synthesis data as well as human activity data has been published in the book PiHKAL.
1,3-Benzodioxolyl-N-methylbutanamine (N-methyl-1,3-benzodioxolylbutanamine, MBDB, 3,4-methylenedioxy-N-methyl-α-ethylphenylethylamine) is an entactogen of the phenethylamine chemical class. It is known by the street names “Eden” and “Methyl-J.” MBDB is a ring substituted amphetamine and an analogue of MDMA. Like MDMA, it has a methylene dioxy substitution at the 3 and 4 position on the aromatic ring; this is perhaps the most distinctive feature that structurally define analogues of MDMA, in addition to their unique effects, and as a class they are often referred to as "entactogens" to differentiate between typical stimulant amphetamines that (as a general rule) are not ring substituted. MBDB differs from MDMA by having an ethyl group instead of a methyl group attached to the alpha carbon; all other parts are identical. Modification at the alpha carbon is uncommon for substituted amphetamines. It has IC50 values of 784 nM against 5-HT, 7825 nM against dopamine, and 1233 nM against norepinephrine. Its metabolism has been described in scientific literature.
2C-G is a psychedelic phenethylamine of the 2C-series. First synthesized by Alexander Shulgin, it is sometimes used as an entheogen. It has structural and pharmacodynamic properties similar to 2C-D and Ganesha. Like many of the phenethylamines in PiHKAL, 2C-G and its homologs have only been taken by Shulgin and a small test group, making it difficult to ensure completeness when describing effects.
Proscaline 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.
Ganesha (2,5-dimethoxy-3,4-dimethylamphetamine) is a lesser-known psychedelic drug. It is also a substituted amphetamine. It was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage range is listed as 24–32 mg. The drug is usually taken orally, although other routes such as rectally may also be used. Ganesha is synthesized from 2,5-dimethoxy-3,4-dimethylbenzaldehyde. Ganesha is the amphetamine analog of 2C-G. It is a particularly long lasting drug, with the duration listed in PiHKAL as being 18–24 hours, which might make it undesirable to some users. It is named after the Hindu deity, Ganesha. Very little is known about the dangers or toxicity of ganesha. Effects of ganesha include:
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, who named it after the first letter of the Hebrew alphabet. In his book PiHKAL, Shulgin lists the dosage range as 5–10 mg, with effects typically lasting for 6 to 8 hours.
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 .
3,4-Methylenedioxy-N-hydroxyamphetamine is an entactogen, psychedelic, and stimulant of the phenethylamine and amphetamine chemical classes. It is the N-hydroxy homologue of MDA, and the N-desmethyl homologue of MDHMA. MDOH was first synthesized and assayed by Alexander Shulgin. In his book PiHKAL, Shulgin listed the dosage range as 100–160 mg, and the duration as approximately 3–6 hours. He describes MDOH as being very psychedelic and producing increased pleasure in beauty and nature. He also mentioned several negative side effects also seen with MDMA ("Ecstasy") such as difficulty urinating and internal dryness.
3C-BZ (4-benzyloxy-3,5-dimethoxyamphetamine) is a lesser-known psychedelic drug and a substituted amphetamine. 3C-BZ was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage range is listed as 25–200 mg and the duration as 18–24 hours. According to anecdotal reports from the substance's entry in PiHKAL, 3C-BZ's effects can vary significantly, ranging from intensified emotions and strange dreams, to effects similar to those of LSD or TMA. Very little data exists about the pharmacological properties, metabolism, and toxicity of 3C-BZ.
Asymbescaline (3,4-diethoxy-5-methoxyphenethylamine) is a lesser-known psychedelic drug. It is a homolog of mescaline. Asymbescaline was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage range is listed as 200–280 mg, and the duration listed as 10–15 hours. Asymbescaline produces few to no effects. Very little data exists about the pharmacological properties, metabolism, and toxicity of asymbescaline.
Buscaline (3,5-dimethoxy-4-butoxyphenethylamine) is a chemical compound prepared as a possible psychedelic drug. It is an analog of mescaline. Buscaline was first synthesized by Alexander Shulgin. In his book PiHKAL, the minimum dosage is listed as 150 mg, and the duration is "several hours". Buscaline produces no psychedelic or psychoactive effects, but causes heart arrhythmia and light diarrhea. It does not cause any visuals or insights. Very little data exists about the pharmacological properties, metabolism, and toxicity of buscaline.
3,4-Methylenedioxy-N-hydroxy-N-methylamphetamine is an entactogen, psychedelic, and stimulant of the phenethylamine and amphetamine chemical classes. It is the N-hydroxy homologue of MDMA ("Ecstasy"), and the N-methyl homologue of MDOH. MDHMA was first synthesized and assayed by Alexander Shulgin. In his book PiHKAL, Shulgin listed the dosage range as 100–160 mg, and the duration as approximately 4–8 hours. He describes MDHMA as causing entactogenic and open MDMA-like effects, easing communication, and increasing appreciation of the senses.
Beatrice is a lesser-known psychedelic drug. It is a substituted methamphetamine and a homolog of 2,5-dimethoxy-4-methylamphetamine (DOM). Beatrice was first synthesized by Alexander Shulgin. In his book PiHKAL, the minimum dosage is listed as 30 mg, and the duration listed as 6–10 hours. Beatrice produces a vague feeling of openness and receptiveness, and causes a stimulative effect. It also causes diarrhea. Very little data exists about the pharmacological properties, metabolism, and toxicity of beatrice.
BOB (4-bromo-2,5,beta-trimethoxyphenethylamine) is a lesser-known psychedelic drug. It is the beta-methoxy analog of 2C-B. BOB was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage range is listed as 10–20 mg, and the duration listed as 10–20 hours. BOB produces an altered state of consciousness, tinnitus, a pleasant tingling throughout the body, and a sense of awareness. Very little data exists about the pharmacological properties, metabolism, and toxicity of BOB.
4-methylallyloxy-3,5-dimethoxyphenethylamine is a lesser-known psychedelic drug. It is the 4-methyl analog of allylescaline. MAL was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage range is listed as 40–65 mg, and the duration is listed as 12–16 hours. Little data exists about the pharmacological properties, metabolism, and toxicity of MAL. The effects of MAL are comparable to that of other mescaline analogs, although with a longer duration. MAL has been sold as a designer drug. At very high doses MAL, as well as the psychedelic amphetamine DOI, causes neuroinflammation and loss of serotonergic neurons in mice.
Thioescaline (TE) is a pair of lesser-known psychedelic drugs with the chemical formula C12H19NO2S. They structural analogs of escaline in which an oxygen atom has been replaced with a sulfur atom.

Little information exists on the human pharmacology of 3C-AL and it has little-to-no history of human use. It can be synthesized from syringaldehyde by reaction with allyl iodide followed by condensation with nitroethane and reduction. The hydrochloride salt is a white crystal with a melting point of 180–181°C.
