Home » Pre Workout » Muscle X Edge Review – Does It Really Work?

Dreaming of rock-hard abs and toned arms?

Is that beer gut hanging on for dear life no matter what exercise you do?

Muscle X Edge might be the solution to all of your problems.

Using an all-natural blend of ingredients that are completely safe, this product promises to help you develop lean muscle quickly.

Don’t think you can get away with not exercising at all, though.

You will never bulk up sitting on the couch regardless of how many supplements you take.

How Muscle X Edge Work?

Similar to other products, Muscle X Edge uses a blend of amino acids, the building blocks of muscle and other tissues.

It also claims to increase blood flow by boosting the level of nitric oxide in your blood.

Nitric oxide is a known hemodialator, so those claims may prove accurate.

The Muscle X Edge website lists A-AKG as the reason for these great benefits — does this compound actually work that way once it has been ingested?

Ingredients in Muscle X Edge

A-AKG or arginine alpha-ketoglutarate, is the salt of two amino acids, arginine and alpha-ketoglutarate.

Two studies specifically examine claims made by many different supplement manufacturers and their findings offer some good reasons to be suspicious of A-AKG.

One, performed on twelve college-aged men at Sacred Heart University in 2011, showed that the test group’s performance was unaffected by taking A-AKG.

In fact, in the study abstract, the authors wrote, “Because AAKG supplementation may hinder muscular endurance, the use of these supplements before resistance training should be questioned.”

In another study conducted at Baylor University in 2011, 24 active men were given AAKG supplements for seven days to measure its effect.

The researchers concluded after those seven days that increases in nitric oxide levels could be attributed to the resistance exercise and not the supplements.

Ornithine alpha-ketoglutarate (OKG) and glutamine-alpha-ketoglutarate (GKG) are two additional forms of amino acids, and while certain research does show they help your body build muscle, there is no conclusive proof.

Other articles we found during our research also support the notion that these two acids can fight free radicals.

Free radicals lead to cell degeneration, so getting them out of your body faster is very good, especially if you trying to build muscle.

Whether this is true or not, is, again, up for debate.

We simply need more empirical research to definitively say that any of these compounds will help you increase your muscle mass.

So I Shouldn’t Buy Muscle X Edge?

The main issue we have with Muscle X Edge is the fact that their is a free trial.

But that sounds like a good deal, right?

You get to try the product for free, what do you have to lose?

Well, you actually think your getting a free “sample” of Muscle X Edge, but the reality is that if you don’t cancel that trial within a couple of weeks, they end up charging the hell out of you.

If I were you, I would stick with something else.
