What Is Muscle Pro Xtreme?

Muscle Pro Xtreme is a capsule form nitric oxide booster intended to increase sports performance, amplify bodybuilding results and improve fitness. It impacts muscles and helps the body maintain important levels of glutamine. By taking this supplement, the product claims that men and women see an increase in muscle mass and enjoy an increase in stamina. Muscle Pro Xtreme also purports to help consumers achieve a lean muscular body while elevating their aerobic endurance and performance. These results translate into higher self-esteem, as men and women are able to feel more confident and powerful from a toned, fit body.

Using a scientifically proven formula, Muscle Pro Xtreme asserts that it aids purchasers in maximizing their body’s performance. Results include both physical and mental benefits. Within two weeks, customers are said to notice greater exercise performance, as muscle fatigue occurs much later into an exercise. The supplement encourages fat cells to convert into lean muscle with 15% faster muscle tissue recovery. Through it all, the manufacturer claims that the product’s natural ingredients hydrate the body’s blood cells to maintain an enhanced body chemistry.



Labgenix is listed as the manufacturer of the Muscle Pro Xtreme brand. Labgenix offers customer contact information within the brand’s terms and conditions. By purchasing any products from Labgenix, consumers agree to the company’s policies, including verification that the customer is age 18 or older. The manufacturer is registered as a home-based business operating out of San Diego. Quite likely, this means that it is a white label product that offers products under other different brand names with varying labels affixed to the products.

Customer care and billing inquiries for this manufacturer are directed to 7770 Regents Rd., Suites 113-178 San Diego, CA 92122. Numerous other brands operate from this address, namely skin care products.


How Muscle Pro Xtreme Works?

According to brand instructions, consumers take two capsules each day 30 minutes prior to a workout or right after waking in the morning to acquire noticeable results. Muscle Pro Xtreme activates human growth hormone-producing parts of the body. The increase in human growth hormones directly impacts muscle growth. With age, the body slows down production of the human growth hormone, eventually ceasing to exist altogether. When this happens, the body’s naturally occurring building and rest cycles transfer into defense mode, leading to a loss of new muscle development in exchange of maintaining one’s current status. Muscle Pro Xtreme seeks to reverse the aging process by upping the amount of HGH.

To improve body mass and bodybuilding performance, as well as boost fat-reducing enzymes, the product relies on three primary ingredients. Although the product’s claims to create “instantly visible muscle definition improvements” are a bit exaggerated and oversimplified, other assertions from the nitric oxide booster are supported by its ingredient list. The presence of L-Arginine is the primary way that the manufacturer can make many of its claims.

Naturally, results depend on proper use of the product and an individual’s body composition. Consumers are advised to balance use of the supplement with other healthy habits, such as eating a diet full of proteins, fruits and vegetables, and maintaining an exercise routine. Other benefits said to exist due to the supplement include:

  • Improved endurance and performance;
  • Conversion of fat cells to cut muscle;
  • Delayed muscle fatigue;
  • Enhanced workout performance;
  • Improved mental focus and physical coordination;
  • Greater stamina, strength and energy;
  • Improved deep sleep cycles;
  • Better regulated immune functioning.


Ingredients of Muscle Pro Xtreme

Dietary, food and sports nutrition supplements containing natural ingredients are legal by default. Since they are not drugs or medications, they do not require any approval from the Federal Drug Administration.

As stated previously, there are three active ingredients in this nitric oxide booster: L-Arginine, Creatine Ethyl Ester and Beta-Alanine. L-Arginine is said to be responsible for androgenic fusion and offers other health benefits. It can be found naturally in red meat, fish and dairy products. L-arginine causes blood vessels to enlarge for better blood flow. L-arginine also encourages insulin to circulate throughout the body as growth hormone and other substances are released.

Beta-Alanine is said to increase the synthesis of carnosine, thereby accelerating muscle strength and endurance during great physical exertion. It is noteworthy that the brand’s own link to scientific data supporting this claim continually misspells the ingredient, which gives pause to the credibility of the company’s claims.

Creatine Ethyl Ester is described as the neuromuscular accelerator of the supplement. The manufacturers state that this ingredient amplifies the body’s ability to recreate Adenosine triphosphate, which produces and stores energy. They assert that it improves overall body composition.

There is credible scientific evidence supporting some of the claims regarding Creatine Ethyl Ester. Specifically, it is shown to improve athletic performance in young, fit bodybuilders. In athletes age 60 and older, however, there is no discernible advantage.



With only two pills to swallow each day, Muscle Pro Xtreme is easy to take. It does not require any alterations to diet or exercise routine. Beta Alanine, Creatine and L-Arginine are all suitable ingredients for a muscle building formula. The supplement supplies the body with additional amino acids, which are the building blocks of muscles. Through the increased blood flow that this product encourages, muscles receive more energy. The company’s billing practices seem legitimate and honorable. Customer service is responsive and friendly.

So far there are not any definitive negative side effects of using Muscle Pro Xtreme. However, L-Arginine, one of its primary ingredients, is under scrutiny. On the plus side, the natural ingredient supports the supply of Nitric Oxide to different parts of the body and fosters vascular relaxation so that blood can flow much easier. The concern stems from people with heart problems who may face unwanted low blood pressure upon taking this supplement.



Certificates and promotional offers for Muscle Pro Xtreme are not readily available on the Internet. There is a free trial period and built-in discount for bulk purchases. That said, there are countless offers of reduced pricing for this product by numerous individuals and subsidiary groups.

Some bidding sites and online markets offer a 30-day supply of the bodybuilding supplement for only 1/6 of the advertised price on the brand’s website. It is noteworthy that Muscle Pro Xtreme’s website features conflicting information about pricing. The landing page for the free trial lists a substantially higher price for the monthly supply than the list price on the Terms and Conditions landing page.



No celebrities or professional athletes have endorsed Muscle Pro Xtreme. However, many testimonials are available online. Some critiques have been created by paid actors, while others seem legitimate. They can be viewed at various shopping portals and on the brand’s website.

Muscle Pro Xtreme claims that 98% of its customers are satisfied with the results. Users are expected to see results within two weeks, which many of the online reviews support.

Muscle Pro Xtreme gave me a big bump in energy, especially when lifting. Remember, this product is meant to enhance your pump, not replace it. I recommend using this supplement to supplement your regular healthy diet and exercise regime. – Alex Garvan, Sydney, Australia

I have used this product before and it works really good, no side effects. You will see more definition in your body after you work out. – Joshua Rahl, Melbourne, Australia

I think I am showing good benefit from Muscle Pro Xtreme. I am kind of new to using it, but my energy has definitely increased. I feel more energized and confident at the gym, more in tune with both mind and body. So far so good and I haven’t cancelled yet. I think I may have found my product of choice. I’ve been looking awhile, so that is a good thing. – Scott Mead, Canberra, Australia

Muscle Pro Xtreme is not a scam. Read all the fine print and you will see that you can simply call and ask for a trial offer and get a huge discount. If you get off your a** and use it properly, it actually does work. I have been using it for two months now and I am really impressed. If it would work any faster, it wouldn’t be safe. – Caleb Tavers, Brisbane, Australia

I was amazed at how quickly I saw results after taking Muscle Pro Xtreme. Almost immediately, I could tell that my stamina had improved and I wasn’t nearly as tired even after a strenuous exercise routine. The first couple pills seemed to cause a little nervousness or jitters, like I’ve experienced when I’ve pulled an all-nighter with caffeine, but nothing remarkable. – Carlos Santiago, Adelaide, Australia
