What Is Muscle Factor X?

Muscle Factor X is a proprietary blend of natural ingredients designed to raise your body’s testosterone levels and give you more energy before your workout. This pre-workout supplement supercharges your body’s natural processes to increase your pump and let you have longer, more efficient gym sessions. The L-Arginine that makes up the bulk of this blend of natural amino acids serves as a body-boosting catalyst that with results that few other supplements can attain.

In order to get the most out of Muscle Factor X, it is recommended that you take it twice a day. One pill at breakfast and one pill at in the early to mid afternoon will give you the best results. Since it is a powerful fat burner, you should not be taking it at night so that your body can go through its natural sleep rhythm.

Getting jacked does not need to be hard when you are taking an effective daily pre-workout supplement. You will notice your body starting to respond fairly quickly, giving you a leg up in the gym. Gains will start coming faster and you will feel like you can go for hours, leading to more muscle mass and higher fat loss.



Muscle Factor X is manufactured by the company of the same name. The brand specializes in pre-workout supplements that enhance the body’s natural ability to lose weight. In addition to weight loss, the company tends to focus on testosterone boosting as well, making their supplements fairly powerful when it comes to a pre-workout option.

Since it came onto the market in 2012, thousands of people have gotten help to attain their goals of lowering their BMI and increasing muscle mass. The number of people who have tried it, and the length of time it has been on the market, seems to point to a successful product. Since the manufacturer is based in the consumer-friendly state of Florida, the team behind the product stands behind what they offer with a money back guarantee.

Because the manufacturer firmly believes in what they are selling, they do offer a refund guarantee if you are not happy with the results. They are able to do this because almost nobody asks for a refund since they start seeing gains relatively quickly. However, as a respected company in the supplement market, the option is available and you can talk to someone on the phone if you need help using the product or help with your order.


How Muscle Factor X Works?

Muscle Factor X works by stimulating your body in a way that jump starts its natural processes. This is done by using a unique blend of all natural ingredients specifically formulated for those looking to lose weight and gain lean muscle mass. The supplement works by attacking the problem of low energy and existing fat tissue in three basic ways.

One of the most important aspects of this supplement is the ability for it to increase your metabolic rate. When your metabolism rises, it is easier for your body to burn calories, leading to a loss in fat. Since those burned calories need to be used by your body, you feel more energized and less lethargic. The increased metabolic rate usually starts to kick in within a day or two of starting the daily regimen, though it can take up to a week before it kicks into full gear.

The increase in energy from a faster metabolism is part of the total energy added to your body, but the supplement itself acts as a sort of pump inducer that makes your muscles feel less tired throughout the day and especially during your workout. An increase in muscle pump is generally caused by an increase in blood flow to your biggest muscle groups. When you take a daily pre-workout supplement, your body starts to develop a routine that aids your cardiovascular system in delivering enough oxygen to the various parts of your body.

Finally, as you expend more energy and your body’s metabolic rate increases, you will experience a boost in your testosterone levels. Higher testosterone levels usually leads to feeling even more energetic, allowing you to stay in the gym longer, train harder, and feel less anxious during the day. Men with low testosterone levels generally complain of a tired feeling, irritability and the inability to work out for as long as they used to in the gym.


Ingredients of Muscle Factor X

The main ingredients of Muscle Factor X are three variants on the L-Arginine protein including the base amino acid, as well as the monohydrate and alpha glutarate proteins. Each of these biological chemicals have a slightly different effect on the body, making it important that they are all included in combination with the other ones. As the main ingredients, their primary purpose is to increase nitric oxide activity in your body which gives users the metabolic and testosterone boosting benefits.

In addition to L-Arginine, you will also find lesser known chemicals such as L-Citrulline, which is mainly added for its testosterone boosting qualities. Though the body’s testosterone levels will boost with an increase in energy levels, L-Citrulline amplifies this effect to make it even more powerful. As a relatively minor ingredient, you will not find more than 5 mg in a tablet, roughly amounting to about half of 1 percent of its total weight.

Another ingredient found in very low quantities is Dipotassium Phosphate, which is a water soluble salt that helps keep the rest of the ingredients fresh during the manufacturing process and extends its shelf life. Without this, the supplements would need to be taken within days of coming off of the line, making it impossible to create in bulk. You can find Dipotassium Phosphate in almost any pre-packaged food you might buy from the grocery store and it is a relatively minor ingredient with only 4 mg included in each tablet.



Energy is in abundance when taking Muscle Factor X and this is especially important when you are working out. In order to get the most out of a gym session, a pre-workout supplement is just about a requirement to keep your body primed and your energy levels up to a point where you can start developing big gains. When you have more energy and use it as you workout, you will find that you will be able to recover faster the next day.

Since this twice-daily supplement boosts your testosterone when taken on a daily basis, your body will not suffer from the effects of low-T. Many men starting at around age 35 may see a natural decline in testosterone levels and while this is normal, it does not necessarily have to happen. Taken just twice a day, you can hold on to the testosterone production your body already puts out and build upon it. Higher testosterone levels leads to more efficient gains and your body is able to repair your muscles in a timely manner.

Having a faster metabolism is important when you are trying to trim body fat. As long as you keep your caloric intake lower than what your body expends in a day, you will start to see the weight shed off. It does not matter if your current metabolic rate is fairly low, average, or even higher than normal, you should see a faster rate with regular use. As your body breaks these fats down, the energy needs to go somewhere, if you channel it correctly, it can basically go straight into your muscle mass.

The three main advantages of Muscle Factor X all work in a symbiotic relationship with each other. High energy levels lead to a quicker metabolism and higher testosterone levels while the other two do the same thing for your energy levels. Finding all of this in a pre-workout supplement is something you do not see every day.



Since the ingredients are all natural, the FDA does not require Muscle Factor X to go through the same time consuming application process that prescription medications must go through. What is found in the supplement is inherently safe.

Perhaps the best certification is the fact that the manufacturer has been distributing their flagship product for almost four years and there are so many people on the internet happy with it. As a pre-workout supplement specifically designed to trim body fat, users would catch on quickly if it did not work as it is advertised.

Unfortunately, there are few publications or organizations that give out certificates for pre-workout supplements. Most of the time, word of mouth will be the biggest motivator for someone trying something new. While there may be a lack of certificates for this product, its users know what to expect and exactly what it can do for them.



I could feel the pump going through my veins after about 15 minutes. It was a great feeling, especially once I got in the gym. My usual workouts last around an hour, maybe a little longer, but with Muscle Factor X, I wasn’t even feeling beat after the two hour mark. This is definitely a supplement worth the money.

– Rodger R., Dallas, TX

At first, I was skeptical about taking what was supposed to be a workout pill during the day but I got used to it. Even with the same amount of exercise, I could see that I was losing more weight than usual and it felt like I had more energy. After a few days it felt like second nature to take a pill in the morning and one right after lunch.

– Mike T., Philadelphia, PA

Having tried other types of vitamins and supplements before my regular workouts, I didn’t have super high hopes for Muscle Factor X. I was pleasantly surprised when my max lifts started increasing quicker than I thought. My body feels like it can just keep going once I’m working out, whereas in the past I’d start to feel a little winded after just a few sets.

– Jack R., New York, NY

Muscle Factor X uses a secure credit card processing server that has several layers of security both on site, and on the processor’s side. The website is verified as “safe” by Google, which routinely checks websites listed in their search engine.

Security starts by using a secured https protocol on the purchase page, which is standard for most credit card checkout pages online.

All user information is kept secure in the processor’s data center which are always protected by multiple electronic countermeasures, as well as secured physical facilities with guards.


Pricing & Free Trial

Even if you only use it for a few months, it can more than pay for itself when it comes to muscle gain. Some people pay far more for gym memberships, personal trainers, or home gym equipment. For a pre-workout supplement, the price is more than reasonable.

In addition, there is a free trial available if you want to test it out before going for a full month. All you need to pay is $7.95 for shipping and handling. This is a great way to see how your body reacts to the supplement before committing to everyday use.
