What Is Horlaxen?

Horlaxen is a pre-workout supplement designed to help you add more muscle and increase stamina without necessarily changing anything about your workout routine. This supplement works to support workout intensity and also to facilitate faster recovery. It does this by acting as a support for nitric oxide. Nitric oxide works by increasing blood flow to working muscles via a phenomenon known as vasodilation, or widening of the blood vessels. This mechanism is important, as it increases blood flow without increasing blood pressure. Strength training, and lifting heavily in particular, increases blood pressure temporarily. Any additional blood pressure increase can prove to be dangerous. The increase in blood flow, however, has some very important benefits for your workout. One is oxygen delivery. Whether you’re doing cardio or strength training (or both), delivery of more oxygen will further your workout. As we all know, oxygen is vital for athletic performance as well as general function.

Ensuring that your working muscles get copious amounts of oxygen has a substantial impact on your athletic performance. Lactic acid builds up in the muscles as oxygen wanes, and it’s this accumulation that is responsible for the burning sensation you get as you near the end of a set. Obviously, you can’t prevent the buildup of lactic acid entirely. But by increasing the amount of delivered oxygen, Horlaxen allows you to keep lifting longer, since it delays the lactic acid buildup. However, oxygen delivery isn’t the only way in which this supplement supports your workout. By increasing the delivery of blood to muscle tissue, this supplement also makes sure that supplements and other vital nutrients hit the tissue as they’re supposed to. This helps ensure you get maximal muscle growth. Many lifters take BCAAs (branched-chain amino acids) as an intra-workout supplement, and optimal blood flow means that this supplement can help you lift heavier and also help you start your recovery early. Additionally, this supplement gives you a powerful muscle pump that will help you look and feel ripped.

Although this is a supplement that can really help you to improve endurance and performance while lifting, it also can help you to get the most out of recovery. As you likely know, much of your muscle growth takes place during recovery, and optimizing your time when you aren’t in the gym can do great things for your physique. Because this supplement increases blood flow around the clock, and not just while lifting, you get the benefit of increased nutrient delivery all day. This means that your post-workout supplements, including protein, glutamine, and anything else you take, can really give your muscles the full benefit of your supplementation routine. Muscle tissue is primed for growth post-workout, and taking your protein while Horlaxen is in fell effect can make sure more of it goes to muscle building. In short, this is a supplement that is sold as a pre-workout, but it also works quite well as a general muscle and metabolic support for those who want to get the most out of their lifting routine.



This supplement is made by a German manufacturer that provides little information about itself online. It looks as though this supplement may be the only supplement it makes. Buyers may be a bit concerned about purchasing from a foreign manufacturer. However, there are some upsides to Horlaxen’s unique manufacturing situation. One benefit is the fact that a foreign supplement has managed to be placed in the American supplement market. Since the American supplement market has grown considerably over the last few years, it’s unusual that a supplement originating in another country can even make it to this market. The fact that this supplement is for sale here likely says something about its efficacy. Further complicating things is the fact that the return address for refunds is given as “Nathan’s Naturals,” so the manufacturer of this supplement may be related to this company.


How Horlaxen Works?

As noted above, this supplement works by stimulating the body to produce more nitric oxide. Nitric oxide is a compound that increases the delivery of blood to muscle tissue. It does this by widening blood vessels. The manufacturer makes some unusual claims about how this supplement works, including stating that it boosts testosterone by 140 percent, reduces exhaustion by 47 percent, and increases muscle growth by 50 percent. However, it does not go into detail as to how these stats were measured or obtained. Moreover, this supplement only has one ingredient, the nitric oxide booster L-arginine. While there’s no way to prove the stats the company claims (and, not to mention, L-arginine is not a testosterone booster), there is very well-documented evidence on how L-arginine works.

L-arginine is the original nitric oxide booster. This supplement was used for years in the fitness community, but nobody knew how it worked. They only knew that it seemed to increase endurance and overall workout performance. Eventually, a team of researchers got together and decided to investigate. They found that L-arginine in the body caused an increased production of the vasodilator nitric oxide, which increased the delivery of oxygen and nutrients to muscle tissue. This study may have remained somewhat unknown, but it was the recipient of the 1998 Nobel prize in medicine. This reinforced what many in the fitness community had known for decades- that L-arginine was an extremely useful supplement for lifters.

So how exactly does increasing blood flow help? To start, it supports longer, harder workouts. Anytime you have vital compounds and oxygen delivered to your muscles at a higher rate than before, you end up with delayed and lessened muscle fatigue. Whether you want to get more reps in or lift heavier with fewer reps, decreasing fatigue and your perception of it can help. Increasing blood flow also helps you to recover more completely. Since protein and other supplements are delivered to muscle tissue via the blood, increasing blood flow ensures that more of your supplements reach those tissues, thus allowing them to recover faster and grow more. While there’s no way to confirm the Horlaxen manufacturer’s seemingly made-up statistics, there’s plenty of evidence that the main ingredient works. L-arginine may not work in all the ways that the manufacturer claims that it does, though – for instance, there is no evidence to suggest that it increases testosterone directly.


Ingredients of Horlaxen

While many pre-workout supplements contain many ingredients, this supplement only contains one ingredient, the nitric oxide booster L-arginine. In the ingredient listing, it is noted that L-arginine alpha-ketoglutarate is included. This is a very important consideration, as different forms of this amino acid work differently. For instance, Arginine alphaketoglutarate is L-arginine bonded to AKG, a molecule that some studies suggest actually supports peak athletic performance. Another format, L-arginine HCl, is broken down quickly in the body but does not have the chemical advantages of AKG.

While having only one ingredient may make this supplement seem less desirable, it is useful to know that the form of L-arginine included here is one of the better forms for those who want to improve upon their peak athletic abilities. Because many pre-workout supplements use inferior forms of L-arginine, they may not work as well as a supplement that uses a high-quality form like L-arginine alphaketoglutarate.



There are many advantages to choosing Horlaxen as your pre-workout supplement. one of these advantages is the fact that it comes in easy to take caplet form. Of course, some users prefer a mixable drink, but if you’re in a rush or have limited space in your gym bag, the tablet form can help. Another advantage is the lack of stimulant. Many pre-workout supplements contain stimulants, which can be good for supporting energy and focus. However, for those who are sensitive to stimulants, these are not ideal. While you can take a lower dose of a pre-workout with ingredients you’re sensitive to, this can result in you not getting enough of the ingredients that support muscular growth. If you prefer a stimulant, you can always add one to Horlaxen before you lift. One last advantage is the fact that this manufacturer lists the amount of L-arginine alphaketoglutarate. many low-level supplements rely on proprietary blends in order to protect their formulas. But if you don’t know how much of a given ingredient is in something, you have no way of knowing if you’re taking enough. This listing helps you make sure you get the right amount of L-arginine for you workout and body type.



This supplement has yet to earn any certificates. There are a few reasons this could be. one is the fact that, in Germany, the system for recognizing and awarding supplements is a bit different from the one in the United States. While the U.S. could award Horlaxen with a certificate, the sheer size of the U.S. supplement market frequently results in even extremely deserving supplements not getting the recognition they deserve. There are many, many supplements on the market, and a comparative few even get reviewed or seen by certificate-awarding agencies. It is possible that, in time Horlaxen may get the recognition it seeks.



When you buy a supplement online with no free trial, it can be tough to choose one based on what you read alone. For that reason, below are some of the words from those who have tried this supplement and used it as part of their supplement routine:

– Jonas, 31, Berlin, Germany:

I had never really used pre-workouts when lifting while growing up, but after college I started lifting more seriously and realized that I needed something to help me through the rigors of a tough lifting routine. i researched pre-workouts before I bought one, and I decided that AAKG was something I really, really needed in a supplement. It took me awhile to find a manufacturer that listed the amounts of included ingredients, too. But I found this one! It’s been three months and I look better and can lift heavier, mostly because I’m so much less sore than before. I’m thankful that this is the pre-workout I found first.

– Bill, 44, Topeka, KS, USA:

The older I get, the more I realize that I need a little extra help when lifting. I don’t mean steroids! But I kept getting tired in the middle of my workout, and I knew something needed to change. Then, I decided I’d go ahead and get a pre-workout. i had no clue what i was doing or looking for, but I found this first. I like to save money and went with the four-bottle package, which was a great idea for me. I noticed that my focus improved, my energy – everything. My lifts got better over six months, and now I’ve hit a few PRs, too. This is good for guys like me who need a boost.

– Josh, 22, Laramie, WY, USA:

I used to be very overweight, and i bought this because I thought it was some kind of stimulant. Turns out it isn’t, but the truth might have even been better. I realized it kept me lifting heavy when before I might have just given up. I also noticed that I stopped being quite so sore the next day. This was also important, since I used to be the type of guy who would skip my workout if I was too sore, unfortunately. I’m no longer overweight, thanks in part to this, and my endurance is so much better than it used to be. This was a great find.

– Steven, 38, Memphis, TN, USA:

I’m not even all that old, but I knew that I needed something to really take me to the next level, and I found it in this stuff. I used to love stimulant-heavy pre-workouts, but i got to a point where I couldn’t stomach them anymore. I’m still not sure why. But this let me lift really heavy without having to deal with stimulants. It supported my mental health too, maybe because i got physically healthier overall. I’ve been buying for a year and am so glad i found it.


Awards & Media Coverage

As noted above, the sheer size of the supplement industry often means that even top-quality supplements don’t get reviews and coverage. Horlaxen has yet to get any major media coverage, but it has been reviewed ons several supplement sites. While these don’t get it quite the same exposure as a review in a major magazine would, getting reviews anywhere is helpful. many supplement review sites have quite a following, and seeing a reviewed supplement can help keep it on the radar of potential buyers. In time, this supplement may well receive more media coverage, but for now, it is still relatively unknown.


Money-back Guarantee

The manufacturers of Horlaxen stand by the product they make. As such, they offer a money-back guarantee. If you are dissatisfied with this product for any reason, you may return your bottle for a refund. To do so, you must send back the whole bottle. You also can only make returns within 30 days of purchase. Once the bottle is received, you will get a refund within five to seven days. You will be charged a 15 percent restocking fee, however. Please note that you will be responsible for return shipping costs and for setting up a tracking number.



Shipping is fast, as the makers of Horlaxen believe you should get your product as fast as possible. When you place your order, your bottle will be shipped to you within a business day. You should receive your order in one to four business days. If you do not see an order within that time frame, you may need to contact the company and ask about your bottle. This company ships using DHL and UPS, depending on your location. They make a note on their website that they only ship out 300 bottles per day, so if time is of concern, you may want to order early in the day in case they run out and can’t ship immediately.


Customer Support

Customer support staff for Horlaxen are all people who are knowledgeable about fitness and health topics, and they are eager to help you achieve your goals. These representatives work to make themselves available to you, and if you try to reach them when they’re out of the office, they will make an effort to get back to you expediently. Even if you aren’t a customer yet, you can still ask questions to try and figure out whether this supplement is a good one for you. Similarly, even if you’ve been a customer for some time, you may still contact the company to ask any questions that can help you better implement this supplement into your current supplementation routine.


Safe & Secure Checkout

For many people, buying online is daunting, and for good reason. In the past, before encryption became a thing, it was easier for people to steal your information online. Now, though, this company and others have started using state of the art technology to help protect your information. This site used encryption, which means that your financial and personal information is coded so others cannot access it. This means that your information is kept safe with this company. You may be worried about employees seeing your information, but if you are, it may help to know that the employees only see your information when they are fulfilling an order.



Pricing of this supplement is on par with many other supplements sold online. The manufacturers of Horlaxen offer several deals for those who want to buy more than one bottle. If you do just want to buy one bottle, it costs 49.95 Euro, which is $55.71 USD. If you buy three bottles, it costs 33.90 Euro each (or $37.81 USD), and buying four means that you get them for 29.95 Euro (or $33.40 USD) each. While this supplement company doesn’t offer the free trial, the tiered pricing program allows you to choose buying one bottle to ensure you like it, or buy many to save money. One advantage of this system is that there is no autoship program to cost you extra money or lock you into a contract. Each purchase is a one-time cost.


There are many benefits to choosing this supplement as your pre-workout supplement. They include the following:

  • This supplement contains one of the most effective forms of L-arginine.
  • The manufacturer does not use an autoship program.
  • Each ingredient is backed by significant research.


As with any supplement, this one has some downsides. they include the following:

  • The manufacturer makes several unsubstantiated claims.
  • Some may prefer a trial program where they can try the product risk free, and Horlaxen doesn’t have this.


Summary: Horlaxen is a supplement that is designed to support your workout goals. This is a supplement with only one ingredient: L-arginine alpha-ketoglutarate. This is one of the more valuable forms of L-arginine, as alpha-ketoglutarate has been shown in some studies to increase peak athletic performance. This supplement works by boosting nitric oxide produced in the body. Nitric oxide allows the blood vessels to expand, thereby increasing the delivery of blood to the muscle tissue. Since blood delivers oxygen and nutrition to the muscles, this allows you to exercise with more intensity for longer periods of time. It also speeds recovery and reduces soreness, while also supporting enhanced muscular growth. While Horlaxen contains only on ingredient, this is an extremely effective ingredient for a pre-workout supplement to have, as L-arginine alpha-ketoglutarate is backed by many studies that have proven its efficacy since 1998. This supplement also comes in caplet form, making it portable and easy to take along with you. It is offered for sale in a variety of non-autoship packages, so you can buy it without fear of commitment.
