説明
1,3-dimethylamylamine or methylexaneamine (DMAA) is a synthetic pharmaceutical patented in the 1940s as a nasal decongestant which can be used as a recreational stimulant. Alleged to occur in nature，DMAA has become a widely used ingredient in sports food supplements, despite its status as a doping agent and concerns over its safety. The most popular brands containing DMAA include Jack3d? and OxyElite Pro?, both marketed by USP Labs and both detained by the FDA in July 2013 (however, some can still be found on Amazon and other online retail stores).

使用
DMAA (1,3-dimethylamylamine) is an amphetamine derivative that has been widely used in sports supplements sold in the United States. Also known as methylhexanamine or geranium extract, DMAA is often touted as a "natural" stimulant, with many claimed functional uses including a body-building aid, an athletic performance enhancer, and a weight-loss aid. Although DMAA at one time was approved as a drug for nasal decongestion, no medical use of DMAA is recognized today. FDA is not aware of any reliable science indicating that DMAA exists naturally in plants.

主な応用
1,3-Dimethylamylamine (1,3-DMAA) is a neural stimulant with a structure similar to ephedrine and adrenaline that has been used as a pre-workout stimulant. It is useful in compositions, for example as dietary supplements, and for appetite suppression. Methylhexaneamine is a botanical ingredient in dietary supplements. Methylhexaneamine and caffeine has been combined in attempts to improve exercise performance and related variables.

薬物動態学
Oral Clearance (CL) values (CL/F; F represents oral bioavailability) were found to be relatively low (20±5.0 L/hr), whereas oral Volume of distribution (V/F) was relatively high (236±38.0 L). A 25 mg single oral dose resulted in a maximum plasma concentration (Cmax) of 76.5 ng/mL, which occurred approximately 4 hours post-ingestion. Cmaxvalues were approximately 15-30 times lower than those reported in case studies linking 1,3-Dimethylamylamine (DMAA) intake with severe adverse events, suggesting that the reported adverse events were associated with a DMAA intake much higher than the 25 mg dose in our study [9,10]. Additionally, the potential impact of drug-drug interactions should be considered when interpreting DMAA adverse event reports. Because DMAA PK data suggest that a significant fraction of an orally administered DMAA dose is metabolized, concomitant administration of common ingredients that are also metabolized (e.g., caffeine), may lead to exaggerated DMAA concentrations by inhibiting DMAA clearance.

副作用
Taking 1,3-Dimethylamylamine (DMAA) can raise blood pressure and lead to cardiovascular problems ranging from shortness of breath and tightening in the chest to heart attack. It may also cause stroke, a condition called lactic acidosis, heart attack, liver injury, and death.
