1,3-Dimethylbutylamine (1,3-DMBA, dimethylbutylamine, DMBA, 4-amino-2-methylpentane, or AMP), is a stimulant drug structurally related to methylhexanamine where a butyl group replaces the pentyl group.
The hydrochloride and citrate salts of DMBA has been identified as unapproved ingredients in some over-the-counter dietary supplements,[3][4][5] in which it is used in an apparent attempt to circumvent bans on methylhexanamine.
[6] The U.S. Food and Drug Administration (FDA) considers any dietary supplement containing DMBA to be "adulterated".
[8] There are no known human safety studies on DMBA and its health effects are entirely unknown.
[3][4][9] DMBA is not an agonist of the rodent or human trace amine-associated receptor 1 (TAAR1).
