What is DMHA (Dimethylhexylamine)?​

DMHA stands for dimethylhexylamine. It is chemically similar to DMAA (1, 3-dimethylamylamine). It has the chemical formula CH3-CH2-N(CH3)-CH2-CH2-CH3.

Its discovery and use date back to the middle of the 20th century. Manufacturers created it as a nasal decongestant or an inhalant for treating bronchitis and laryngitis.

It has found its way into numerous dietary supplements, pre-workout supplements, and energy-boosting formulations over the years. Early in the twenty-first century, its use in nutritional supplements gained tremendous popularity, with manufacturers touting its ability to boost vitality, concentration, and athletic performance.


DMHA as a Stimulant​

Stimulants stimulate the central nervous system, resulting in heightened alertness, increased energy, and enhanced cognitive functions. Influencing the release or reuptake inhibition of neurotransmitters in the brain is predominantly responsible for these effects.

DMHA is classified as a stimulant because it can energize the central nervous system. People compare it to DMAA and caffeine because all three substances are stimulants with the same impact on the body.

While DMAA and DMHA have stimulant properties, the FDA removed DMAA from many products due to legal and regulatory issues. DMHA, on the other hand, has a more favorable reputation on the market, and consumer interest is growing.

The stimulant DMAA is more potent than DMHA and caffeine. Additionally, it is more likely to produce side effects like anxiety, insomnia, and headaches. Caffeine is less effective than DMHA and DMAA as a stimulant. However, it has a lower incidence of adverse effects.

Common Uses of DMHA​

One of the primary applications of DMHA is in dietary supplements designed to increase vitality and improve concentration. DMHA's stimulant properties can produce a rapid and intensive energy surge, making it a popular option for those seeking enhanced productivity and mental clarity.

Athletes and fitness enthusiasts have turned to DMHA to enhance their physical endurance and stamina. The ability of DMHA to increase energy levels can contribute to lengthier and more intense workouts, allowing individuals to exceed their limits during training. It can provide a surge of motivation and energy, enabling users to engage in strenuous exercises with renewed vigor.

The stimulating properties of DMHA have also made their way into the realm of fat burners. People use it to enhance metabolic rate and promote thermogenesis, making it a valuable weight management supplement ingredient.


Mechanism of Action​

DMHA influences the body in a variety of ways. It is a sought-after ingredient in dietary supplements and pre-workout products due to its influence on neurotransmitters and physiological systems.

Its impact on the body can lead to increased release and decreased reuptake of dopamine, a neurotransmitter associated with pleasure and reward. DMHA also influences the production of norepinephrine, a neurotransmitter that plays a crucial role in the body's "fight or flight" response.

Regarding its physiological effects, DMHA may increase heart rate and blood pressure. Activating the sympathetic nervous system, which prepares the body for action, is responsible for this characteristic physiological response of stimulants. DMHA may also have thermogenic properties, increasing the body's heat production and metabolism.

The Pros of DMHA​

DMHA's capacity to increase physical performance is one of its primary benefits. Athletes and fitness enthusiasts frequently use DMHA to enhance their stamina and endurance, enabling them to push through challenging workouts and, more effectively, attain their fitness goals.

DMHA is not limited to physical advantages. In a scientific study published in Brain Sciences journal, it can also considerably improve mental clarity and concentration. Users report feeling more alert and attentive after incorporating DMHA into their daily regimens, making it useful for tasks requiring sustained concentration.

In a bodybuilding forum, a user said DMHA was his best stimulant. However, he had to stop taking it since he was already developing heart problems from his genes. Knowing its effects on heart rate and blood pressure, continuously taking it may lead to cardiovascular problems in the future.

The Cons of DMHA​

Since DMHA is a stimulant, jitteriness or restlessness is among the most commonly reported adverse effects. Users can experience an uncomfortable feeling of nervousness or disquiet, which can be particularly annoying.

It can provide a temporary energy boost but may pose risks, particularly for cardiovascular patients. Heart rate and blood pressure increase can be problematic for individuals with hypertension or heart-related conditions.

The stimulating effects can also lead to sleep disturbances, including insomnia. Users may find it challenging to fall asleep or experience disrupted sleep patterns, which can negatively affect overall well-being.

Because of these side effects, regulatory authorities in several countries have expressed concerns about the safety of DMHA, particularly regarding the lack of sufficient research to establish its long-term safety profile. These concerns have resulted in removing DMHA-containing products from the market in some regions.

Legal Status of DMHA​

The legal status of DMHA varies significantly from one country to another. DMHA is not an FDA-approved ingredient in the United States. However, it is still present in some dietary supplements marketed as exercise aids or weight loss supplements. The FDA has issued warning letters to companies selling DMHA-containing products, emphasizing the importance of safety and regulatory compliance.

In New Zealand, the government has yet to include it as a controlled drug. Still, it needs to meet the requirements for the Medicines Classification Committee to categorize it as a dietary supplement. Instead, manufacturers should only use it as an ingredient in products that offer a therapeutic effect.

Health Canada has also taken action against DMHA-containing products, classifying them as cosmetic ingredients. This classification means that the organization prohibits DMHA as a dietary supplement ingredient.

The World Anti-Doping Agency also included DMHA as a prohibited substance in sports competitions. Additionally, the Ministry for Primary Industries is also still determining the safety of DHMA. Despite regulatory controversies, MPI is open to recommending DHA as a prescription medicine.

Dosage and Bioavailability​

Factors such as an individual's tolerance, body weight, and sensitivity to stimulants can significantly affect the recommended dosage of DMHA. 100 to 150 milligrams is the typical introductory dosage. Regarding blends, it can be challenging to estimate the dosage amount.

DMHA has a bioavailability of about 30%, meaning that only 30% of the amount taken goes into the bloodstream. A 200 mg dose would only result in 60 mg of DMHA reaching the bloodstream.

The half-life of DMHA is approximately 3 to 4 hours, which indicates that it takes about 3 to 4 hours for the amount of DMHA in the body to decrease by half. This half-life means that DMHA's effects can last for several hours.

Stacking and Contraindications​

DMHA can provide an extra energy kick when combined with other energy-boosting supplements like BCAAs. Additionally, if you want to amp up your mental clarity during workouts, pairing DMHA with nootropics like Alpha-GPC can be advantageous. When stacked with DMHA, supplements like beta-alanine can also help delay muscle fatigue, allowing for more extended workout sessions.

Though stacking can improve the energy boost, focus, and weight loss effects, combining multiple stimulants and DMHA can lead to overstimulation, resulting in jitteriness, restlessness, and increased heart rate. It may also lead to dependency, where your body relies on these substances for performance.

It's essential to be cautious about mixing it with certain conditions or medications. If you have hypertension or heart-related disorders, consult a healthcare professional before using DMHA. Monoamine Oxidase Inhibitors may also interact adversely with DMHA and increase the risk of severe side effects, such as seizures and heart attack.

Athletic Performance and Euphoria​

DMHA enhances athletic performance by providing a surge of energy and heightened focus. This energy boost benefits athletes engaged in high-intensity activities or endurance events. It can improve stamina and endurance by increasing oxygen and nutrient delivery to muscles, allowing athletes to push harder and longer during workouts or competitions.

Since it affects the neurotransmitters in the body, DMHA can have mood-enhancing or euphoria-inducing effects. These effects may be due to DMHA's ability to increase the levels of dopamine and norepinephrine in the brain.

The mood-enhancing effects of DMHA are feelings of increased energy, focus, and motivation. Some people also report feelings of euphoria or intense happiness.

Routes of Administration and Popular Brands​

DMHA is commonly available in capsule form. They are pre-measured, making it easy to control your dosage accurately. This convenience is beneficial for individuals who prefer a straightforward approach to supplementation.

It is also available in powder form, allowing users to adjust their dosage according to their preferences and tolerance. Additionally, the body absorbs the powder form more quickly, leading to a faster onset of effects.

The most common over-the-counter brands of DMHA in pre-workout are 1,3D NOX from Total Body Nutrition, Ultimate Orange from Hi-Tech Pharmaceuticals, and Jack3d from USP Labs. On the other hand, the most common brands of DMHA with fat-burning availability are Lipodrene and Synadrene from Hi-Tech Pharmaceuticals, OxyElite Pro, and HydroxyElite from USP Labs.

Safety Guidelines​

Consult a healthcare professional before adding DMHA to your supplement regimen, particularly if you have underlying medical conditions or are taking medications. They can offer customized advice based on your health condition.

If you are new to DMHA, begin with a low dose. If necessary, gradually increase the dosage while monitoring its effects. Avoid exceeding recommended concentrations, as doing so may result in adverse effects.

Consider your body's response and stop taking DMHA immediately if you experience adverse effects. After using DMHA, ensure you get sufficient rest and prioritize recovery. Overexertion without proper rest can lead to burnout and potential health issues. Adequate sleep and recovery are essential for overall well-being.


DMHA is a potent stimulant that has acquired popularity due to its ability to enhance energy, concentration, and athletic performance. It provides various prospective benefits, including increased energy, improved concentration, and enhanced physical performance. However, responsible and informed usage is paramount to ensure a safe experience. Individuals considering DMHA-containing products should consult healthcare professionals and adhere to recommended dosages and guidelines to minimize risks.
