α-Ethyltryptamine, also known as etryptamine, is a psychedelic, stimulant, and entactogenic drug of the tryptamine class. It was originally developed and marketed as an antidepressant under the brand name Monase by Upjohn in the 1960s.
Diisopropyltryptamine is a psychedelic hallucinogenic drug of the tryptamine family that has a unique effect. While the majority of hallucinogens affect the visual sense, DiPT is primarily aural.
4-HO-MiPT is a synthetic substituted aromatic compound and a lesser-known psychedelic tryptamine. It is thought to be a serotonergic psychedelic, similar to magic mushrooms, LSD and mescaline. Its molecular structure and pharmacological effects somewhat resemble those of the tryptamine psilocin, which is the primary psychoactive chemical in magic mushrooms.
EiPT is a chemical in the tryptamine family, and produces psychedelic and hallucinogenic effects. It was probably first synthesized by Alexander Shulgin.
2,N,N-trimethyltryptamine, 2,N,N-TMT, or 2-Me-DMT is a tryptamine derivative that is a psychedelic drug. It was invented by Alexander Shulgin and reported in his book TiHKAL (#34). It is claimed to show psychoactive effects at a dosage of 50–100 mg orally, but these are relatively mild compared to other similar drugs, suggesting that while the 2-methyl group has blocked the binding of metabolic enzymes, it is also interfering with binding to the 5HT2A receptor target that mediates the hallucinogenic effects of these drugs.
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.
N,N-Dibutyltryptamine (DBT) is a psychedelic drug belonging to the tryptamine family. It is found either as its crystalline hydrochloride salt or as an oily or crystalline base. DBT was first synthesized by the chemist Alexander Shulgin and reported in his book TiHKAL . Shulgin did not test DBT himself, but reports a human dosage of "1 mg/kg i.m." being active, but less so than DMT or DET. This suggests that an active dosage of DBT will be in the 100 mg range. This compound has been sold as a "research chemical" and has been confirmed to be an active hallucinogen although somewhat weaker than other similar tryptamine derivatives. It produces a head-twitch response in mice.
4-Hydroxy-N,N-dibutyltryptamine (4-HO-DBT) is a psychedelic drug belonging to the tryptamine family. It is found either as its crystalline hydrochloride salt or as an oily or crystalline base. 4-HO-DBT was first made by the chemist Alexander Shulgin and reported in his book TiHKAL. Shulgin reported a dosage of 20 mg orally to be without effects. However this compound has subsequently been sold as a "research chemical" and anecdotal reports suggest that at higher doses 4-HO-DBT is indeed an active hallucinogen, although somewhat weaker than other similar tryptamine derivatives.
MBT, or N-methyl-N-butyltryptamine, is a lesser-known psychedelic drug. MBT was first synthesized by Alexander Shulgin. In his book TiHKAL, the minimum dosage is listed as 250-400 mg, and the duration listed as 4–6 hours. MBT produces a heavy body load with dehydration, and causes visuals similar to those of DMT. Very little data exists about the pharmacological properties, metabolism, and toxicity of MBT.
4-MeO-MiPT, or 4-methoxy-N-methyl-N-isopropyltryptamine, is a lesser-known psychedelic drug. It is the 4-methoxy analog of MiPT. 4-MeO-MiPT was first synthesized by Alexander Shulgin and is mentioned in his book TiHKAL. Subsequent testing by Shulgin on human test subjects showed the effective dose as 20-30 mg ; the onset time between ingestion and the first noticeable effects was 45-60 min, with sensations lasting between 2-2.5 hours. The sensation were significantly milder than those of 4-HO-MiPT, with 4-MeO-MiPT producing erotic-enhancing effects, and few of the visuals common with tryptamines. Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-MeO-MiPT.
5-MeO-pyr-T (5-methoxy-N,N-tetramethylenetryptamine) is a lesser-known psychedelic drug. It is the 5-methoxy analog of pyr-T. 5-MeO-pyr-T was first synthesized by Hunt & Brimblecombe, who credited S. Mitzal for characterization of chemical properties. Later human tests were reported by Alexander Shulgin, in his book TiHKAL. An oral dosage of 0.5 to 2 mg, and an inhaled dosage of 2–3 mg are reported. 5-MeO-pyr-T causes varying reactions, such as amnesia, tinnitus, vomiting, and a 5-MeO-DMT-like rushing sensation. At the highest dosage reported in TiHKAL, the subject describes awakening from an apparent fugue state during which they were wandering the streets, with complete amnesia upon awakening.
5-MeS-DMT (5-methylthio-N,N-dimethyltryptamine) is a lesser-known psychedelic drug. It is the 5-methylthio analog of dimethyltryptamine (DMT). 5-MeS-DMT was first synthesized by Alexander Shulgin. In his book TiHKAL, the minimum dosage is listed as 15-30 mg. The duration listed as very short, just like DMT. 5-MeS-DMT produces similar effects to DMT, but weaker. Shulgin describes his feelings while on a low dose of this drug as "pointlessly stoned", although at a higher dose of 20 mg he says it is "quite intense" and suggests that a higher dose still might have full activity.
5,6-MDO-DMT, or 5,6-methylenedioxy-N,N-dimethyltryptamine, is a lesser-known psychedelic drug. It is the 5,6-methylenedioxy analog of DMT. 5,6-MDO-DMT was first synthesized by Alexander Shulgin. In his book TiHKAL, 5,6-MDO-DMT produces no noticeable psychoactive effects, although it was only tested up to a dose of 5 mg. Very little data exists about the pharmacological properties, metabolism, and toxicity of 5,6-MDO-DMT.
4,5-MDO-DiPT, or 4,5-methylenedioxy-N,N-diisopropyltryptamine, is a lesser-known psychedelic drug. It is the 4,5-methylenedioxy analog of DiPT. 4,5-MDO-DiPT was first synthesized by Alexander Shulgin. In his book TiHKAL, 4,5-MDO-DiPT produces slight LSD-like effects after several hours. Very little data exists about the pharmacological properties, metabolism, and toxicity of 4,5-MDO-DiPT.
4,5-MDO-DMT, or 4,5-methylenedioxy-N,N-dimethyltryptamine, is a lesser-known psychedelic drug. It is the 4,5-methylenedioxy analog of DMT. 4,5-MDO-DMT was first synthesized by Alexander Shulgin, though in his book TiHKAL it was not tested to determine its psychoactive effects. 4,5-MDO-DMT has been the subject of limited subsequent testing; with behavioral disruption studies performed in male rats indicating that its hallucinogenic potency is less than that of 4,5-MDO-DiPT but greater than that of 5,6-MDO-DiPT.
2,α-Dimethyltryptamine (2,α-DMT) is a tryptamine and a lesser-known psychedelic drug. It is the 2,α-dimethyl analog of DMT. Its synthesis was first reported in 1965. Alexander Shulgin lists the dosage as 300-500 mg, and the duration as 7–10 hours in his book TiHKAL. 2,α-DMT causes mydriasis and paresthesia. It also produces a calm, drunk-like feeling. Very little data exists about the pharmacological properties, metabolism, and toxicity of 2,α-DMT.
Alpha,N,O-TMS, or α,N-dimethyl-5-methoxytryptamine, is a lesser-known psychedelic drug. Its abbreviated nomenclature is derived from its structure, as it is α,N,O-trimethyl serotonin. α,N,O-TMS was first synthesized by Alexander Shulgin. In his book TiHKAL, Shulgin lists the dosage as 10-20 mg when taken orally, and the duration as 6–8 hours.
4-Hydroxy-α-methyltryptamine (4-HO-αMT) is a psychedelic drug of the tryptamine class. It is a close structural analogue of α-methyltryptamine (αMT) and produces similar effects to it, but with exacerbated side effects similarly to 5-MeO-αMT. Alexander Shulgin describes 4-HO-αMT briefly in his book TiHKAL:
The 4-hydroxy analogue of αMT has been looked at in human subjects. It is reported to be markedly visual in its effects, with some subjects reporting dizziness and a depressed feeling. There were, however, several toxic signs at doses of 15 to 20 milligrams orally, including abdominal pain, tachycardia, increased blood pressure and, with several people, headache and diarrhea.
2-Hydroxy-N-methyltryptamine (2-HO-NMT) is a tryptamine and is the 2-hydroxy analog of N-methyltryptamine (NMT). It is briefly mentioned in Alexander Shulgin's book TiHKAL under the DMT entry and is stated to be found in Desmanthus illinoensis.
5,6-Dibromo-DMT is a substituted tryptamine alkaloid found in some marine sponges. It is briefly mentioned in Alexander Shulgin's book TiHKAL under the DMT entry and is stated to be found, along with other tryptamines, in Smenospongia aurea and other sponges.
