The Complete DMHA Guide [2021]

While we wait for updates with the DMAA case, DMHA has swooped in and taken its place. In fact, almost every product containing DMAA now features DMHA. But what is this “new” ingredient and what can we expect from it? We’re covering these questions!

What Is DMHA?

As we’ve said time and time again…

DMHA is a DMAA-like stimulant. (1) Originally, or at least medically, it’s used as a decongestant. In supplements, it may help  improve performance and increase weight loss. But, you’re not likely to see “DMHA” on the label of your favorite pre workout or fat burner. It has a TON of different names but here’s a short list of the common ones: (2)

  • 1,5-Dimethylhexylamine
  • 1,5-DMHA
  • 2-amino-5-methylheptane
  • 2-amino-6-methylheptane
  • 2-aminoisoheptane
  • 2-Heptylamine, 6-methyl-
  • 2-Isooctyl amine
  • 2-Metil-6-amino-eptano
  • 6-Amino-2-methylheptane
  • Amidrine
  • Octodrine
  • Vaporpac

This ingredient can come from nature or be made synthetically. Generally, companies are more likely to make it synthetically due to this being the cheaper method. But, it comes from the Juglans Regia tree. In products like (spoiler) Hydroxyelite, this is labeled as Walnut Bark Extract. We’ll talk more about this product and more below but feel free to jump to it!


Is DMHA Legal?

Short answer: As of today, Yes!

Detailed answered: Yes, but it’s complicated. In April of 2019, the US FDA did send out warning letters to manufacturers to remove DMHA from their products. This was due to companies not submitting a New Dietary Ingredient Notification (NDIN), which is required for all new dietary ingredients. Or if DMHA was an unsafe food additive. (3)

But here’s the thing-

DMHA isn’t new. It’s a constituent of walnuts, which has been around for long before any FDA Law. So this isn’t a strong enough case to ban the ingredient. But, what about it being “unsafe”?  Hi-Tech Pharmaceuticals, along with other companies, have been selling products with DMHA for 2(+)  years now. With no serious issues from consumers when taken properly.

And let’s not forget it’s medical use as a decongestant, which has been instated in the 1950s. (4) Therefore, we can’t really ban it for this reason either. And don’t worry if you’ve grown to love DMHA as much as we have, Hi-Tech has fought the FDA for it. And continues to fight for DMAA.

What About Sports?

Being legal in the US is great and all, but what are the chances of a false positive on a drug test?

It’s possible. We can’t guarantee it will or won’t. Generally, if this is a concern for you, we would advise you to stray away from risky products. Not just ones containing DMHA.

But, for this matter, we have a statement from the U.S. Anti-Doping Agency:

“Categorized as a stimulant under the World Anti-Doping Prohibited List, octodrine is prohibited in-competition. Because clearances times depend on many individual factors, USADA cannot advise athletes on when they should discontinue using a substance to ensure that it has completely “washed out” from their body. Octodrine is not included in FDA-approved medications for any medical condition, so USADA would not grant a Therapeutic Use Exemption (TUE) for a product containing the substance.” (5)

If you’re an athlete or if your profession limits what kind of supplements you can take;

Send us an email or talk to one of our Live-chat agents before you buy a product. We can help guide you to products that have been okayed before.


How Does DMHA Work?

As we’ve mentioned, DMHA is a stimulant. It’s structurally similar to 2 familiar compounds (maybe more):

  • 1,3 Dimethylamylamine (AKA DMAA)
  • Amphetamine

Based on that alone, there’s an expectation that it will act like both these compounds. Just not as potently.

Diving in deeper:

There, unfortunately, isn’t many human studies on DMHA to back up its effects. But, due to the methyl group on the alpha carbon, it should have a half-life similar to DMAA and Amphetamine (9-11 hours). And it should act as a monoamine releasing agent (MRA) of catecholamines like DMAA. This includes dopamine and norepinephrine.

Then DMHA binds to the trace amine associated receptor 1. This will temporarily prevent the re-uptake of dopamine and norepinephrine into the presynaptic nerve. By doing this, these catecholamines remain active in your body for longer. This attributes to the euphoric and wakeful feelings we get from ingredients like this. (4)


What To Expect From DMHA?

Alright, so we’ve gone through what happens in the inside. But, what effects can you expect?

Again there are not enough human studies to back up these effects. The following information is based on customer feedback and our anecdotally experiences. Everyone will have a different experience and because DMHA is rarely taken on its own, we can’t guarantee any effect is directly because of it.

With that little disclaimer out:

What’s the feedback?

Customers state the effects last several hours. And that they felt a heightened sense of euphoria during that period of time. This is what we can predict based on the structure and similarities to DMAA. As far as any crash goes, it was reported as a much smoother come-down.

But, adversely the come-up is also gradual. So if you’re looking for a spike of energy, DMHA isn’t for you. Customers also explained that they felt some appetite suppression with the DMHA. This is generally going to be tied to stimulants.


Are There Side Effects?

Any stimulant will have its fair share of risks. Some of the reported side effects include; (4)

  • Nausea
  • Energy crash
  • High blood pressure
  • Heart palpitations
  • Labored breathing
  • Hyperthermia

Reading that list might scare you away from the products below. And if these side effects are a concern for you, you should, in the very least, consult a doctor. But, it wouldn’t be fair to paint DMHA as the bad guy. Not without comparing the side effects to more common stimulants, such as caffeine: (6)

  • Anxiety
  • Insomnia
  • Digestive Issues
  • Muscle Breakdown (in large amounts)
  • Addiction
  • High Blood Pressure
  • Heart palpitations
  • Fatigue
  • Frequent Urination



Congrats! We’re almost at the end of the post. Now we’ve reached the good stuff (and probably why you’re here).


We’ve already tapped into this a little in the “What To Expect” section, but here we’re getting as deep as research lets us. And your feedback of course. To start off, let do a review comparison of our top selling fat burner Hydroxyelite.

Way back when it had DMAA our reviews looked like this:

DMHA Reviews hydroxyelite

The Structure:

DMAA structure

DMAA contains two methyl groups located directly next to the NH2 group on either side. This makes it very effective at blocking MOA and increasing potency.

Compare the structure of DMAA  to the structure of DMHA and you’ll understand why DMHA is said to have about 70-80% the strength of DMAA.

The overall opinion on DMHA to DMAA is that it has a lot of the focus elements, but comes a little short in the energy department. The good news though is that the crash from DMHA is reported as much smoother. Allowing consumers to continue to have a good day long after the stimulant has worn off.

DMHA vs Ephedrine

So the thing with ephedrine is that it hasn’t been available for use in dietary supplements in the US for a long time. It’s not illegal though! Much like DMHA, ephedrine has its use in medicine. In fact, it’s also a nasal decongestant. It’s one of four active components from the plant Ephedra. Now supplements use just ephedra and remove the ephedrine alkaloids. But back in the day ephedrine was very popular for ECA stacks (ephedrine, caffeine, and aspirin). (7) And it’s really common for fat burners today to mimic this stack with ephedra.

But besides their medicinal use, what do these compounds have in common?

It’s actually structurally similar to not only DMHA and DMAA, but also Amphetamine.

DMHA Structure 2

But what do people think?

It’s varied, to say the least. Some people feel DMHA is more like ephedrine than DMAA and some say the opposite. The clear thing is that they are related, which is why even in medicine they share a purpose.


What Products Have DMHA

A lot. It’s actually very popular in fat burners and pre workouts. So we’ll try to include as many popular products as possible but keep in mind this isn’t the full list.

Hydroxyelite By Hi-Tech Pharmaceuticals
Awesome! Review by Jack
A friend recommended this product to me because I had issues over eating, especially late night and continued snacking throughout the day. I’m almost done with my first bottle and I’ve lost 18 pounds. This product requires a lot of water so drink up. Energy is great and controls appetite. On a down side, when working out with heavy cardio such as sprinting or running long distances – my heart rate speeds up were it’s beating hard and makes me puke. To prevent this, I slow my heart rate by resting for a few minutes. Other that that, this product works as advertised. 5 stars. (Posted on 8/6/19)

Lipodrene Elite By Hi-Tech Pharmaceuticals
LOVE IT! Review by Felicia

I tried Lipodrene back in November and loved it. At first, I heard my fit friends talking about how much energy and focus it have them. At the time, I was not eating clean and honestly could not relate. However, as soon as I cleaned up my diet, I began to feel the same energy and focus, and the pounds started falling off. I took a break for a few months and just started again. It works. I love this product! (Posted on 6/13/19)

Stimerex Hardcore By Hi-Tech Pharmaceuticals
Best Ever! Review by Jeremiah 

This is by far the best fat burner I’ve ever taken without any negative side effects. I was a little hesitant about purchasing it at first but then I thought why not everything else has failed me. I’m glad I did. I’ve only been taking it for 2 months at 2 pills per day and I’ve already seen amazing results. I purchased 2 bottles so I still have one more month to go. Can’t wait to see the end result. I highly recommend this fat burner and I intend on using it until I’ve fully reached my weight loss goals! (Posted on 7/12/20)

Im a fan of the old version but they seemed to have got this right without changing very much.
