What Is A DMHA Pre-Workout?

Many supplements contain DMHA (2-amino-5-methyl heptane) as a primary ingredient. In a pre-workout formula, this ingredient plays the role of a central nervous system stimulant. It has various names, including 2-amino-6-methyl heptane, dimethyl hexylamine, octodrine, vaporpac, etc.

Juglan's Regia tree is the main natural source of DMHA. However, it can also be obtained synthetically. Until some decades ago, DMHA was limited as a decongestant. Gradually, further research was conducted to cultivate more information about DMHA, its multiple chemical forms, and its role as a dietary supplement. (1)

Undoubtedly, this chemical is a potent element of sports nutrition and also makes an excellent choice for bodybuilders, weight lifters, and workout freaks. By increasing your energy and focus, a DMHA-based supplement allows you to extend the rep ranges smoothly.

How Does A DMHA Pre-Workout Work?

DMHA supplements give you a sharp focus and boost your energy level so you can deliver better in the gym. Like other stimulants, this pre-workout also has a unique course of action. Its job includes interacting with two main hormones of your body to provide the desired results. Let’s take a deeper look at the functions of a DMHA supplement.

Elevates Dopamine Levels

Your brain produces dopamine neurotransmitters in a particular range. This hormone tends to motivate you and control your urge to do something. (2)

When you consume DMHA, this chemical causes dopamine to go beyond the typical values. As this hormone increases, you feel more determined to do a task, perform strength training, or get a reward. You are less likely to lose focus or give up on challenging exercises. Additionally, the DMHA keeps you alert and energetic till the last rep, making your workouts more fruitful.

Boost Noradrenaline Production

Noradrenaline is a neurotransmitter produced in your body. This neurohormone controls the vigilance you need to perform an action. If these neurohormones are low, you will feel exhausted and unable to concentrate on something. (3) (4)

So, DMHA stimulates noradrenaline production to increase your willpower and interest in a task. These supplements help you do resistance exercises with enhanced focus and strength. Higher noradrenaline levels also provide a sense of satisfaction, which is essential to keep you motivated for the next training session and aggressive workouts.

Pros Of DMHA Pre-Workout

DMHA pre-workouts are very popular for the benefits they provide. The chemical DMHA acts as a powerful stimulant and allows you to work out as you wish. Let’s find out in detail what advantages you can expect from a DMHA supplement.

Increased Energy

DMHA boosts the production of noradrenaline chemicals, which increases your capacity to work harder. DMHA prepares your body for a heavy and more prolonged workout by boosting energy and strength. Thus, you are urged to complete extra reps with an enhanced endurance capacity. Also, you leave the gym without crashing due to increased energy.

Better Mental State

DMHA also provides impressive results in improving and maintaining cognitive functions. It has a vital influence on your mood and behavior. Upon ingesting a pre-workout, DMHA instantly targets your mood-controlling hormones and drives them towards higher values.

Consequently, you feel refreshed, happy, satisfied, and alert. All these behaviors help you put more effort and concentration into your workouts.

These pre-workouts contribute to the amplified perception of motivation and satisfaction. Moreover, you also feel improvement in your well-being.

Helps Fat Loss

These supplements are considered the best fat burners as well. However, it does not incorporate calorie-burning properties. Rather, it works by causing a sudden rise in your energy levels.

As the body produces additional energy and cognitive hormones, you feel stronger and motivated to perform fat-burning exercises. The strength you gain after consumption helps you switch to powerful workouts faster. (5)

DMHA pre-workout also acts as a fat burner in one more aspect. It reduces the perceived hunger and makes it less difficult to stay hungry. This strategy is all you need to follow strict diet plans and ensure faster weight loss. Hence, if you are on the way to weight loss, DMHA-rich pre-workouts will make your journey easier.

Safe Dosage of DMHA Pre-Workout

Pre-workouts containing DMHA are safe to use, provided you have no medical issues or consume them appropriately. The recommended dosage for DMHA ranges from 50mg to 250mg, depending on the metabolism rate of the consumer.

If you are unsure how your body will react to this supplement, you can take 50mg of the product initially. You can increase the dose gradually to find out your tolerance level to this chemical.

We also recommend you to stick to the dosage amount suggested by the manufacturer of the supplement you choose. Moreover, you can seek advice from a wellness professional or sports nutritionist.

Cons Of DMHA Pre-Workouts

As DMHA places numerous benefits at your hand, it may also cause a few health problems in some individuals. Therefore, it is necessary to know the possible harsh consequences you may incur due to the use of DMHA.


DMHA and many other pre-workout stimulants share a common side effect, which is anxiety. If consumed in excessive amounts, DMHA overly stimulates the central nervous system. Hence, people experience anxiety attacks after ingesting this supplement.


In rare cases, DMHA also disturbs the digestive system. The symptoms include bloating and nausea. This side-effect also occurs as a result of large dosages.

Behavioral Disorders

In some individuals, the immunity system offers zero tolerance for DMHA. Such people show awkward behavioral changes, such as frustration and mood swings.

Heart Palpitations

Some DMHA supplements increase blood pressure and heart rate to provide muscle pumps. You have to be extra careful in dosage. The exceeding amounts may result in irregular heartbeat and other heart abnormalities. (7)


If you consume DMHA daily, you may develop an addiction to this supplement. This happens when such dietary supplements remain in use for a long time.

Who Should You Not Use DMHA Pre-Workout?

A DMHA pre-workout is a worth-buying supplement for bodybuilders, gym-goers, and athletes. However, there is a group of people who should either stay away from this product or think well before using it. The adverse effects associated with DMHA can deteriorate their health and mental condition. Make sure you are not one of them.

Pregnant And Nursing Ladies

DMHA can be dangerous for a fetus. Thus, if you are an expecting mother, avoid it. Moreover, you can consult a doctor for a more reliable opinion.

Heart Patients

Those with irregular blood pressure and heart problems should steer clear of DMHA pre-workout supplements. This supplement further elevates blood pressure, which can be bad for heart patients. 

People With A Recent Surgery

Considering postoperative care, we recommend you avoid pre-workout supplements and drugs as they may affect the healing of incisions or trigger the pre-operation condition. Thus, if you have had surgery lately, try not using a DMHA-based pre-workout until you completely recover.

Are DMHA Pre-Workouts Legal?

For many gym-goers, the legal status of DMHA is questionable. Moreover, it is most often misunderstood with DMAA. If the legality of DMHA deters you from using it, we have a simple, short, and clear answer to this query.

DMHA is legal in the US, UK, and many other countries. Many nasal decongestants have this chemical in their formula. However, its use as a dietary supplement is not declared valid by the FDA.

That’s why many pre-workout companies receive warning letters to stop adding DMHA to their pre-workout products. Abiding by this law, some manufacturers have stopped producing their best-selling DMHA supplements. 

Comparison Overview Between DMHA And Other Stimulants

As the popularity and demand for pre-workout supplements rise, many stimulants are being used to prepare these supplements. Among all, DMHA, DMAA, and caffeine are very common. Scroll down to see what similarities and differences exist between these stimulants.


The chemical structure of DMAA is 1,3-dimethylamylamine. Compared to DMHA, DMAA is 20% more powerful and effective for weight loss and stamina development. This is because it has two methyl groups attached to the alpha carbon, whereas DMHA has only one methyl group in its structure.

If not suited to a body system, DMAA creates a life-threatening situation by increasing the blood pressure uncontrollably. Apart from hypertension, it also increases the risk of cardiovascular and breathing problems. Due to its high-risk factor, this drug is banned as a food component in nearly every country. (8)

DMHA Vs. Caffeine

Caffeine is available in almost every three out of five energy-boosting pre-workout supplements, the reason being the effectiveness. It blocks adenosine receptors to suppress your pain perceiving tendency. Hence, you feel less tired and stronger enough to lift heavier weights and go for some additional reps. (9)

On the contrary, DMHA intake leads to a surge in dopamine and noradrenaline neurotransmitters. This will increase your enthusiasm to strive for better athletic and exercise performance.

One more difference lies in their functions. Caffeine does not elevate mood or behavior, but DMHA significantly impacts cognitive abilities.

Both DMHA and caffeine take an hour to activate fully and show visible effects. But the effects of DMHA last longer than caffeine.

Caffeine and DMHA have some side effects in common. Both cause digestive issues and anxiety and can be risky for pregnant and breastfeeding women. Like DMHA, caffeine dosage recommendations should also be strictly followed to prevent adverse effects.

Final Thoughts

DMHA pre-workout supplement is a considerable source of energy, endurance, and alertness and adds a significant value to your diet. Its effects are similar to DMAA, a banned and illegal stimulant.

By uptaking dopamine and noradrenaline, DMHA enables you to focus on the ongoing activity and put more effort into doing it successfully. Moreover, it reduces the feeling of hunger and also serves as a fat burner.

So, if you want to lose stubborn body fat or eliminate laziness, it’s time to switch to a new supplement. When included in a pre-workout, this chemical makes heavy workouts manageable.
