2,5-Dimethoxyamphetamine (2,5-DMA), also known as DMA-4 or as DOH, is a drug of the phenethylamine and amphetamine families. It is one of the dimethoxyamphetamine (DMA) series of positional isomers. The drug is notable in being the parent compound of the DOx (4-substituted-2,5-dimethoxyamphetamine) series of drugs.

2,5-DMA is said to be inactive as a psychedelic, at least at the doses that have been assessed. However, it has been reported to produce some stimulant-like effects, as well as sympathomimetic effects and mydriasis. The dose range is said to be 80 to 160 mg and its duration is 6 to 8 hours.

2,5-DMA is a low-potency serotonin 5-HT2A receptor partial agonist, with an affinity (Ki) of 2,502 nM, an EC50Tooltip half-maximal effective concentration of 160 to 2,352 nM (depending on the signaling cascade), and an EmaxTooltip maximal efficacy of 66%. It has also been assessed at several other receptors. The drug did not appear to bind to the monoamine transporters, at least at the assessed concentrations (up to 7,000 nM). It was inactive at the human trace amine-associated receptor 1 (TAAR1). 2,5-DMA shows dramatically reduced potency as a serotonin 5-HT2A receptor agonist compared to the DOx drugs, such as 2,5-dimethoxy-4-methylamphetamine (DOM).
