About Superior Muscle X

Superior Muscle X is claimed to be a superior herbal dietary supplement that contains an L-Arginine blend of amino acids and herbal supplements to help boost nitric oxide levels in your blood stream, resulting in: 

  • Faster muscle gains, 
  • A boosted libido and enhanced sex drive, 
  • Increased strength and ability to lose fat, 
  • and more.

But you’re already familiar with Superior Muscle X’s sales pitch. Now, you’re here to find out if it can make you look better with your shirt off, and make you simply irresistible. So can it? Probably not, and here’s why:

What is Nitric Oxide? Are There Any Benefits for NO Supplements?

First, let’s briefly take a look at what nitric oxide does inside your body.

According to NutritionExpress, nitric oxide is a molecule that floats around in your blood stream, and is responsible for transmitting information between nerve cells in the brain, regulating blood pressure and reducing inflammation, increasing endurance and strength, and improving blood flow. Because of its effects on the body, increased levels of nitric oxide have been attributed to helping improve cardiovascular health, easing the symptoms of erectile dysfunction, and more.

But even though increased nitric oxide can provide some clear benefits, do the ingredients contained in Superior Muscle X help increase NO levels, and can you realistically expect to achieve the benefits claimed by the manufacturer?

What Ingredients Does Superior Muscle X Contain? Are They Effective?

According to the Superior Muscle X website, the supplement causes “Arginine Alpha-Ketogulutrate [to be] released into the bloodstream increasing nitric oxide production. Increased nitric oxide will give you an extended and enhanced "PUMP" feeling during and after training sessions.”

But other than claiming to be an “L-Arginine blend of amino acids and herbal supplements,” there aren’t any ingredients listed on the primary Superior Muscle X website. However, we did locate another of the product’s websites that claims the supplement contains:

  • Vitamin B3, B6, and B12
  • Arginine
  • L-Carnitine
  • Chromium
  • Green Tea Extract
  • Yohimbine Bark Extract

According to WebMD, there is insufficient clinical evidence showing that vitamin B3, B6, B12, or chromium can provide any benefits related to weight loss, libido or sexual function, or any of the other benefits claimed by Superior Muscle X’s manufacturer. This isn’t to say there aren’t any benefits related to these substances; just none of the ones claimed by Superior Muscle X.

On the other hand, green tea extract may increase mental alertness due to its caffeine content, arginine is possibly effective for erectile dysfunction, l-carnitine is possibly effective for male infertility (although not necessarily libido or sexual function), and yohimbe is possibly effective for impotence (but again, not necessarily sexual function).

Keep in mind though that there’s no product label provided on the Superior Muscle X website, so we can’t know how much of these ingredients are contained in the supplement, or whether or not these quantities are sufficient to provide any results.

At best though, it’s likely the only benefits you’ll receive from the use of Superior Muscle X is slightly increased alertness, and perhaps slightly improved erections and sexual desire.

Advertising Tactics

Perhaps because Superior Muscle X’s ingredients likely don’t provide all of the benefits claimed by the manufacturer, the company resorts to some less-than-stellar advertising tactics to convince you to buy.

As noted by SupplementCritique, the first of these is creating websites that are intended to look like legitimate articles from popular fitness magazines, but are really just one big advertisement. In addition to featuring only marketing content, these sites will often include fake celebrity endorsements, as with the Ryan Reynolds “endorsement” noted in the article above.

These fake articles (also known as “farticles”) will also generally include images that make you think the company’s products have been featured in popular fitness magazines, although there’s almost never any third-party verification of this (including with Superior Muscle X).

On top of this, the manufacturers of supplements like Superior Muscle X will design their websites to cause you to make an emotional decision instead of an informed one. While we covered this in detail in our How Weight Loss Ads Convince You to Buy article, this includes featuring fit, attractive models, and creating a sense of urgency by making you think there’s only a limited supply.

Consumers Don’t Seem Too “Pumped” About Superior Muscle X

Although Superior Muscle X seems to have been available for several months, there weren’t any legitimate online customer reviews available at the time of our research, so it appears the company may have only recently begun promoting it in earnest.

Instead, what we encountered when searching for Superior Muscle X reviews were affiliate websites that had been set up to look like real reviews, but were actually just more marketing material from the company (see here and here as prime examples of what we’re talking about). However, the SupplementCritique article noted above concluded that Superior Muscle X is highly unlikely to work and that “there’s nothing revolutionary about their formula.”

From a company perspective, we learned that Superior Muscle X, based out of La Jolla, CA, holds a B- rating with the Better Business Bureau, based on only 2 closed complaints (as of 1/23/15), both of which seem to be related to billing issues.

Arbitration Agreement

Finally, according to Superior Muscle X’s Terms & Conditions, keep in mind that you’ll be submitting to an arbitration agreement when placing your order, which will significantly restrict your legal recourse against the company, including taking the company to court due for damages or becoming part of a class action lawsuit.

Superior Muscle X Pricing & Refund Policy

Superior Muscle X is only available through a “free” trial, for which you’ll pay $4.95 S&H and will receive a 30-day supply of the supplement.

The Superior Muscle X trial begins on the date your order is placed, and once it expires, you’ll be charged $98.63 for the full price of the product. At this same time, you’ll also be enrolled in the company’s autoship program, which means you’ll continue receiving a fresh supply of Superior Muscle X once every 30 days, and your credit card will be charged $98.63 each time.

Important note: Because free trials are rarely free, and autoship programs are an easy way to hook you into recurring charges, it’s our professional opinion that it’s best to avoid products sold through these methods.

According to Superior Muscle X’s Terms & Conditions, “We will not provide any refunds or accept any returns for any cancellations made more than 15 days after placing Your order.” In other words, once your trial has expired and you’ve been billed full price, no refunds are available.

However, in order to cancel your autoship enrollment, you’ll need to contact customer service at 888-659-8337.

Is Superior Muscle X the Superhero of Nitric Oxide Supplements?

Chopping to the Point: Considering the lack of clinical evidence available showing Superior Muscle X’s ingredients will provide the claimed benefits, the company’s less-than-stellar marketing tactics, and the fact that it’s only available through a “free” trial and subsequent autoship program, it’s our opinion that Superior Muscle X’s price is far out of line with any benefits you can reasonably expect to achieve from using it.

    Total Scam. I got suckered into two months of payments. If you offer a good product there is no reason to mislead or rip people off by hiding in very small print that you are going to auto charge and ship your product at $90.00 a month. Stay away from this dishonest company.

    Bottom Line: No, I would not recommend this to a friend
