DALT
DALT is a tryptamine derivative and psychedelic that has been identified as a designer drug. It was first described in the scientific literature by Stephen Szara and colleagues by 1962, and has been used as an intermediate in the preparation of radiolabeled DET. Its analogues include 4-HO-DALT, 4-AcO-DALT, 5-MeO-DALT, and several other allyl-substituted tryptamines.
Dosage & Duration
Dosage
Doses are population estimates that vary widely between individuals.
Shulgin reports exploring DALT up to 42 milligrams, reaching only a +1 in an hour with a return to baseline at the fourth hour; TiHKAL states the dose is greater than 40 mg orally with unknown duration.

Subjective Effects
Legacy content. A statistically backed ontology from Mindstate Design Labs is coming soon.
Reports describe a stimulating tryptamine state combining euphoria and emotional openness with mild perceptual change. Self-experimentation up to 42 mg orally produced only a threshold-level effect that peaked within an hour and returned to baseline by the fourth hour, with no features the experimenter found notable. Early accounts group its activity with that of other short-acting tryptamines such as DMT and DET, describing rapidly developing sympathomimetic effects alongside perceptual, emotional, and thinking disturbances.
Physical
Both mental and physical stimulation are reported, accompanied by restlessness, muscle tension, sweating or chills, decreased appetite, pupil dilation, and difficulty sleeping.
Autonomic
Cognitive
The headspace is described in terms of euphoria, empathy, insight, and ego softening, though confusion and general alterations in perception are also reported.
Visual
Visual effects reported are modest, limited to colour brightening and visuals with the eyes both open and closed.
Hallucinatory States
Tactile
Pharmacology
Pharmacodynamics
The receptor interactions of DALT have been studied, though specific targets are not detailed. In rodents, DALT produces the head-twitch response, a behavioral proxy for psychedelic effects.
Pharmacokinetics
Interactions
An unlisted combination is an unknown one, not a safe one. Check a dedicated combination chart before mixing.

History & Culture
DALT was documented by Alexander Shulgin as entry #57 in TiHKAL, where the synthesis proceeded through the quaternary salt N,N,N-triallyltryptammonium iodide. Treatment of that salt with phenylmercaptan and sodium hydroxide in refluxing acetone, followed by acid-base workup, distillation, and…
