When it comes to pre-workout supplements, it is necessary to talk about DMAA that was in hot demand a few years early. It has been banned in several countries because of its high potency and constant side effects.With untiring efforts of developers, at the beginning of 2017, DMHA has become a ‘perfect’ substitute for DMAA, which not only is a popular ingredient of pre-workouts and fat burners, but also can greatly reduce side effects and pour into the fitness industry a strong power.DMHA is actually a set of two different DMAA-like stimulants that can reach 80% the effects of DMAA at appropriate doses. There two versions are named : 2-amino-6-methylheptane, and 2-amino-5-methylheptane. They works in the same fashion: by boosting dopamine and noradrenaline uptake, while slowing down reuptake just long enough for a solid workout or study session. 2-aminoisoheptane’s structural relations are known as monoamine releasing agents, which are compounds that have the capability of increasing levels of certain monoamines. These monoamines, most notably dopamine and norepinephrine, are responsible for exerting many of the common effects that stimulants produce – including enhanced euphoria and wakefulness (alertness), respectively. But this class of compounds is less intense than amphetamine, and has far better safety parameters in animals. It’s also speculated that this will increase blood pressure, but the rise will be less than that of DMAA.
