To the Editor: 1,3-Dimethylamylamine (DMAA) is a substance with amphetamine-like effects found in bodybuilding and weight-loss products and recreational drugs (also marketed as methylhexaneamine, dimethylpentylamine and geranium).1 DMAA was recently banned in Australia and other countries owing to toxicity, lack of health benefits, and concerns about long-term safety and potential for misuse.2 However, published evidence for safety concerns has been remarkably limited; just a few cases report cerebral haemorrhage and cardiomyopathy.1
