    Summary dose.wiki PsychonautWiki

    2,5-DMA is a research chemical and the simplest member of the DOx family, primarily known as a precursor in synthesizing other psychedelic amphetamines rather than for its own psychoactive effects. Unlike typical psychedelics, it produces primarily stimulant and physical effects with minimal to no sensory or perceptual changes. Very little data exists about its pharmacology, metabolism, and toxicity.
