What Is Xtreme Muscle Pro?

Xtreme Muscle Pro is a capsule form bodybuilding supplement which uses natural ingredients to improve muscle cell production. It is said to boost fat-reducing enzymes and hydrate blood cells within the body. The brand claims that their product works to safely and effectively accelerate digestion and metabolism.

Xtreme Muscle Pro is claimed to be an advanced stacked formula for both pre- and post-workout as a lean muscle supplement which increases blood flow, improves metabolism, aids in muscle recovery and improves energy. Their claims continue as saying that users will experience an immediately accelerated ability to increase muscle mass, reduce muscle fatigue and get ripped.

Muscles & Xtreme Muscle Pro



The owner of Xtreme Muscle Pro brand is listed as Labgenix. Labgenix provides customer care contact information in the brand’s terms and conditions. However, the company itself is registered as a home based business in San Diego. This means that the product is likely a white label product also available under other brand names with different labels applied.

Labgenix customer care is also listed as San Diego. That address for shipping and receiving is 7770 Regents Road #113-178, San Diego, CA 92122. Multiple sister brands are managed from this same location, including skincare products.


How Xtreme Muscle Pro Works?

This product uses three primary ingredients as the basis for its claims of building body mass, performance improvement and other benefits. Two capsules are taken each day by the bodybuilder user to acquire these results, according to brand instructions. Additional claims of the product include:

  • Instantly visible improvements in muscle definition;
  • Increased strength, energy and stamina;
  • Improved mental acuity and physical coordination;
  • More self-confidence from the positive results of a toned physique;
  • Improved endurance and performance;
  • Faster muscle tissue recovery;
  • Conversion of fat cells to cut muscle;
  • Delayed muscle fatigue;
  • Enhanced workout performance;

While “instantly visible muscle definition improvements” is a bit of a stretch for a product benefit claim and depends upon the individual’s body, proper use of the product and their fitness regimen, other claims can be linked directly to key ingredients. L-Arginine is a key amino acid toward nitric oxide production and its existence in the product helps with much of the brand’s claims.

The Effects of Xtreme Muscle Pro


Ingredients of Xtreme Muscle Pro

There are three key ingredients in this product. Creatine Ethyl Ester is named as the neuromuscular accelerator of the supplement, while L-Arginine is named boldly as responsible for androgenic fusion. Beta-Alanine is the product’s primary amino acid and anabolic stimulator, although even the brand’s website of “scientific data” repeatedly spells the ingredient incorrectly. One must wonder, if they cannot properly spell the ingredient, if they are fully able to purport truths about its qualities in their product.

The inclusion of Creatine Ethyl Ester in this supplement is said to be a neuromuscular accelerator by the manufacturers. Their statements assert that this ingredient increases muscle uptake of creatine, leading to better regeneration of adenosine triphosphate, a chemical responsible for generation and storing of energy. They also say that Creatine Ethyl Ester improves muscle mass, levels of serum in the body and overall body composition.

The good news is that Creatine is scientifically indicated to improve athletic performance of healthy, youthful athletes and bodybuilders during brief high-intensity workout. However, it is shown that people of older ages, primarily age 60 and higher, enjoy no benefit from the substance. Many famous athletes use or have used Creatine, including overachievers like Mark McGuire, John Elway and Sammy Sosa.

Many bodybuilding supplements boast that Creatine is not in their formula. This is not because Creatine is harmful or banned. It is because collegiate sports organizations are banned from paying to supply products with Creatine to their athletes. By boasting that products are “Creatine free,” that manufacturer is flagging itself as something collegiate team dollars can support. In essence, Xtreme Muscle Pro having Creatine in its formula is not a black mark against it, but means that colleges and universities cannot buy it for students.

Creatine Monohydrate is another form of Creatine used in some supplements. Xtreme Muscle Pro uses Creatine Ethyl Ester. Unfortunately, Creatine Ethyl Ester is not as effective as Creatine Monohydrate at increasing muscle mass, strength or power. In fact, Creatine Ethyl Ester is shown in many studies to not outperform placebos. This means that the form of Creatine used in Xtreme Muscle Pro may actually be an ineffective form of the otherwise bodybuilding component of many supplements.

The Benefits of Xtreme Muscle Pro

The next primary ingredient of the brand’s three key ingredients is L-Arginine. L-Arginine is an amino acid which increases the body’s production of nitric oxide. When the body produces nitric oxide, blood vessels expand and more oxygen and nutrients are delivered more effectively to all parts of the body, including the muscles.

The upside of nitric oxide boosting, as through Xtreme Muscle Pro, is that the user feels more energized, alert and powerful. L-Arginine helps with brain activity so much, that it is used to help patients with dementia regain some control of their mental faculties. So, many people who take L-Arginine bodybuilding supplements feel mentally sharper, as a positive side effect.

The downside of nitric oxide boosting is that it can make people with heart issues, low blood pressure or other ailments feel weak. It can have the opposite of the desired effect in people with unhealthy hearts and even produces some negative effects beyond the weakness. Some individuals may feel nausea, vomit or faint. This is more rare in bodybuilding individuals who tend to have healthy hearts and blood pressure, but has been known to occur.

L-Arginine, as contained in this supplement, also has been shown to increase growth hormone production in the body. Growth hormone is responsible for, just as it sounds, growth of the body. While taking L-Arginine will not make a person grow taller, it does help bodybuilders grow muscle mass. In other words, L-Arginine can create that bulking muscular look that bodybuilders want.

The last of the primary ingredients in Xtreme Muscle Pro is Beta-Alanine. This is the one always misspelled by the brand, so you have to wonder how strong their own results investigation for their product has been, if they are not aware they are not using the ingredient’s name properly. While that sounds petty, it can be hard to take scientific claims seriously from a company not aware of the ingredient’s real name.

On the upside, Beta-Alanine is an amino acid, just as L-Arginine is one. Beta-Alanine aids in development of protein fibers. Muscles are composed of protein fibers. As a result, proper addition of this element aids in muscle mass development, strength and endurance.

A Real Photo of Xtreme Muscle Pro

While naturally produced by the body from foods we eat, taking Beta-Alanine as a supplement is possibly helpful beyond food provision. Beta-Alanine, as found in Xtreme Muscle Pro, is indicated to improve physical performance during strength training. This supports claims by the product that it provides improved physical performance.

Beta-Alanine is also shown in some studies to produce muscle mass in men undergoing resistance training, but that is when it is grouped with specific elements. Those elements are not in Xtreme Muscle Pro. They include Creatine Monohydrate, Arginine, Alpha-Ketoisocaproate and Leucine. Xtreme Muscle Pro contains Creatine Ethyl Ester, the less effective form of Creatine versus Creatine Monohydrate, and does not contain Alpha-Ketoisocaproate and Leucine of the effective grouping.



The product is easy to take, in capsule form. Users simply swallow two capsules per day and do not need to make any changes to diet or exercise regimen, when used in conjunction with a healthy bodybuilding or athletic program. L-Arginine is a proven component which offers benefits typical of amino acids supporting nitric oxide production boosting in the body.

A Comparison of Xtreme Muscle Pro



Certificates, coupon codes and promotions are not readily available on the Internet for this product, outside of the free trial period offer and bulk purchasing packages resulting in a built-in discount. However, there are individuals and affiliates selling this product competitively all over the web.

Shopping portals and bidding sites have the a 30-day supply of the bodybuilding supplement listed for as low as $29.95. That is an incredible difference over the free trial period’s one month supply at an eventual cost of $120, as advertised on the brand’s website. Instead of paying a whopping $4.00 per day, you can find alternative purchasing means to pay as little as $1.00 per day. It is important to note that the brand’s website has a discrepancy in pricing information, as their Terms and Conditions list the product value and price at only $89.95, whereas their free trial offer landing page lists the prices of an initial $100 and subsequent $120 per bottle.

The Checkout Safety for Xtreme Muscle Pro



There are no celebrity or professional athlete endorsements of this product. However, there are many reviews online. Some reviews are listed on the brand’s own website and shopping portals also have purchaser reviews.

I love this stuff. I have been on Xtreme Muscle Pro for about four months and I am much more cut and energetic than I ever was before. I didn’t change anything about my regimen or routine and still noticed good results from using the product. I do have more energy and am going to continue using it.

Steve Akers

I think I am showing good benefit from Xtreme Muscle Pro. 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.

The Testimonials of Xtreme Muscle Pro


Money-back Guarantee

The brand has a fairly comprehensive Terms and Conditions page on their website. This alone can provide shoppers with a little more confidence, when purchasing the product. That Terms and Conditions page does include refund information and other directives.

To discuss the guarantees and refunds for product purchases, a customer service telephone number is provided. That number is 866.883.4981. Customer service personnel answer the line according to Pacific Standard Time, from 8:30 a.m. to 4:30 p.m., Monday to Friday, except holidays. The product return address is 7770 Regents Road #113-178, San Diego, CA 92122.

As for a returns policy, Xtreme Muscle Pro will provide a credit for unopened containers of the product at the limit of one bottle per customer. Beware of this condition, if you are purchasing multi-bottle packages offered on the website. That return must be postmarked before the end of thirty days following order purchase.

The package for return must have a customer service-provided return merchandise authorization number (RMA) clearly marked. Customers are responsible for paying for shipping on all returned products and will not be refunded for shipping of the original order or the return. Without an RMA, the package will not be accepted, so gaining that number from customer service is critical.

The Efficiency of Xtreme Muscle Pro

According to the brand’s terms and conditions, all refunds are issued within one to two days after the return is received and approved. Of course, this is for returns of customers who obtained an RMA number and followed requirements for deadlines of the return. It also is for unopened product containers, only.

For customers who do not receive their order or when the order is lost, they must contact customer service after five days following their order placement. If they use the customer service number and notify that their product has not been received, these customers will receive an extension on their free trial period and the product will be reshipped. Because all orders are sent with delivery confirmation tracking, the customer must be proven to have not received the package according to this tracking record.

Free trial period program participants are not provided with a refund of any kind when they cancel program participation. The customer is still charged for the first order’s shipping fees and must pay to ship unused product back to the company. However, if the cancellation is made in time and according to the program’s guidelines, the customer is not presented with charges for the actual product on their credit card. If the customer does not comply with the cancellation requirements after calling customer service, they are billed for the original 30-day supply bottle, charged a cancellation fee and must pay for any additional product they have received.



Shipping for these bodybuilding supplements is $4.95 per monthly supply and the free trial program’s initial package. All shipping is paid by the customer when the product is ordered, as well as for any returns. Shipping service is through the United States Postal Service, presumably Priority Mail. It includes delivery confirmation for security of both ends of the transaction.

A free trial period is offered for new customers wanting to try the product before receiving monthly shipments and as part of a membership package of other inclusions.

When you enter into a free trial arrangement for purchasing product, you are provided with access to the program portal website. It is not known how frequently that website is provided with additional information, guidance or fresh content. It is also not known how long that site will remain active, so it is important that customers understand it is a minor add-in to be considered beyond the free trial of the actual product.

Free trial pricing is $89.95 per 30-day supply, plus shipping and handling of $4.95 per monthly shipment. You will receive auto-shipments for every thirty days, if you do not cancel your program participation within the first 14 days after placing your order.
