DMAA is a neurological stimulant which causes a quick spike of energy similar to caffeine and other classical stimulants, but does so by different mechanisms in the brain.

It was first introduced as a nasal decongestant as 'Germanium Oil Extract' but more recently is used as a neurological stimulant and party pill.

Due to its structural similarity to amphetamines, it gives a false positive in drug tested competitions for amphetamines and thus should not be used by competing athletes
