BP Limitless 20 (20MG 1,3-DMAA) (1,3-Dimethylamylamine) is a neural stimulant with a structure similar to Ephedrine and adrenaline that has been used as a pre-workout stimulant.
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.
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.
A typical starting dose of 1,3-DMAA is in the 10-20mg range and eventually reaching up to 40-60mg a day, there is no actual evidence to support this dosage range but it seems to be the standard dosages range for supplemental 1,3-DMAA on the market.
1,3-DMAA is known to be banned by various sports organizations due to its amphetamine-like nature, and should not be used by tested athletes.
