Dave's Rating: 2 stars

Guys want to get ripped. They want toned arms, washboard abs, and a cut, muscular back. Basically, we all want to look like Leonidas from 300. Muscle Factor X promises those results using, “a patented blend of natural ingredients that has been formulated to build lean muscle, increase energy, and burn excess fat.”  

How Does Muscle Factor X Do That?

Many body building supplements and powders increase your protein intake and give you more energy, helping you stay in the gym longer, while the protein repairs muscles post workout. But Muscle Factor X claims to actually raise your body’s testosterone levels with a natural blend of ingredients. It also promises to increase your performance and burn fat, giving you that toned, cut look we’re all working toward. That’s not all, though. In addition to all of these benefits, this product supposedly promotes muscle growth even during a “growth plateau.”  

Work out regularly, and you will probably experience this plateau, a period of time when your muscles fail to grow at the rate they did when you first started exercising. It can be extremely frustrating for even the most dedicated fitness enthusiasts. One solution that’s gotten a lot of attention thanks to P90X is so-called “muscle confusion.” The basic premise is to change the type and intensity of the exercise once you’ve hit that plateau, forcing your muscles to adapt.

Ingredients and Formula of Muscle Factor X

Muscle Factor X uses a combination of ingredients — dipotassium phosphate, L-citruline, and various forms of L-arginine — to generate muscle growth even during the dreaded muscle plateau. This sounds great, but does this combination of what are essentially amino acids really work?  

muscle factor x ingredientsAmino acids are the most common component found in human muscle tissue other than water, and there are over 500 varieties of the compound. Your body uses these acids to build muscle, among other purposes. Two of the ingredients in Muscle Factor X, dipotassium phosphate and arginine alphaketoglutarate, are just water-soluable salts.

The latter is marketed as a body building supplement, but no scientific evidence suggests that taking it improves performance. L-citruline, another amino acid, is also thought to enhance muscle training, but again, tests show that this isn’t necessarily true.  

But one ingredient is shown to improve your athletic performance and that is L-arginine. This partiuclar compound is often used by bodybuilders to bulk up because it stimulates the production of growth hormones.  

The Bottom Line  


Muscle Factor X promises great results, but our research shows that many of the ingredients aren’t scientifically proven to help you build muscle, with the exception of one. That one ingredient, L-arginine, is a common supplement used by bodybuilders to help boost the production of growth hormones. Will this help you work through the dreaded muscle plateau? Yes, combined with a diverse workout regiment, Muscle Factor X may help you get over that lull in muscle growth and get ripped.  


Each bottle contains 60 pills and retails for $79.95, but for those of you who are reluctant to spend that much, you can opt for a free trial bottle. Shipping is not included, so you will have to pay the $7.95 shipping and handling fee. Ordering a trial bottle does automatically enroll you in a subscription plan, so if you aren’t satisfied with the product, you must cancel your order within 14 days.  


Is it worth a try? As you may already know, we are not a big fan of “risk” free trials, as many of them prey on unsuspecting customers.  We’re gonna have to give Muscle Factor X a thumbs down.
