About NO2 Maximus

NO2 Maximus is a nitric oxide supplement that’s claimed to help you improve strength, endurance, recovery, and pumps, maximize your workouts, and to help you build muscle mass faster. As a result, NO2 Maximus is claimed to give you a more athletic, chiseled, built, and lean body.

In order to accomplish this, NO2 Maximus is claimed to contain a proprietary blend of natural ingredients that maximize oxygen and nutrient delivery to your muscles. In fact, it’s claimed to be so effective that it can “re-engineer your body within 30 days!”

As you probably already know, if it sounds too good to be true, it probably is. But is NO2 Maximus the real deal, or just more hype in a bottle? Consider the following:

What Ingredients Does NO2 Maximus Contain?

After reading through the NO2 Maximus website, there isn’t a product label provided, and the only ingredients we’re told about are l-arginine and l-citrulline.

With this said, the manufacturer does include an Ingredients section on their website, although it’s interesting to note that, other than l-arginine, the manufacturer doesn’t actually tell us what’s in it.

Instead, they include sections titled “Not recommended for person currently taking blood thinning medications” and “Not for long-term use,” and then go on to list dozens upon dozens of different ingredients, but don’t specifically state which of these are actually included in the supplement (if any), or in what amounts.

Are NO2 Maximus’s Ingredients Effective?

On the NO2 Maximus website, 4 studies are referenced to back up their claims:

  • An overview of l-arginine claiming that it may help athletes improve training efficiency, although this referenced “a mixture of amino acids that included the branched-chain amino acids, arginine and glutamine” (not just the arginine found in NO2 Maximus). In addition, the “training efficiency” only related to muscle recovery and increased oxygenation, not performance.
  • A study showing that l-citrulline helped increase the transport of nitric oxide within the body.
  • A 2010 overview on l-arginine’s potential anti-obesity benefits, although all but one of the trials referenced were conducted on animals, not humans.
  • A 1999 study about the possible benefits of high-dose l-arginine supplementation for men with erectile dysfunction.

With all of this in mind, WebMD lists l-arginine as “possibly effective” for treating many circulatory-related conditions, including chest pain, high blood pressure, leg pain associated with poor blood flow, and erectile dysfunction. For the latter though, patients were given 5 grams of l-arginine, and without a product label, there’s no way to no how much l-arginine NO2 Maximus contains, or whether it’s enough to be effective.

On the other hand, there is insufficient clinical evidence showing that l-citrulline can provide any of the benefits claimed by NO2 Maximus’s manufacturer.

Other Nitric Oxide Supplements

Finally, we’ve reviewed many of the most popular NO2 supplements here at HighYa, including Maxx NO, Superior Muscle X, and Blackline Elite.

And while none of these options have any more clinical evidence supporting their claims than NO2 Maximus, the point is that you have numerous options from which to choose, including some that are likely available at a local supplements store.

What are Customers Saying About NO2 Maximus?

For the most part, NO2 Maximus is promoted only through a network of independent affiliates who earn commissions for each sale of the supplement they refer. As such, these affiliates will often create fake review websites that are specifically tailored to trigger you to make a purchase.

However, we did find one legitimate NO2 Maximus review on SupplementCritique, who noted that the supplement didn’t give them anywhere near the benefits claimed by the manufacturer, and that their billing practices should raise a red flag.

NO2 Maximus Pricing & Refund Policy

NO2 Maximus is only available through a 14-day trial for $4.95 S&H, for which you’ll receive a full 30-day supply of the supplement.

Then, once your trial expires, you’ll be billed $89.91 for the full price of the product, and will also be enrolled in the company’s autoship program. This means you’ll continue receiving a fresh supply of NO2 Maximus once per month, and your credit card will be billed $89.91 plus $5.95 S&H each time.

Important note: In our experience, free trials and autoship programs are really just sneaky methods of getting ahold of your credit card number and consistently charging you for a product you probably didn’t want in the first place. As such, we typically recommend avoiding products sold only through these methods.

Outside of the trial, NO2 Maximus comes with a 30-day refund policy, less S&H charges and a 15% restocking fee, although this only applies to unopened bottles.

In order to request a refund, or cancel your trial or autoship enrollment, you’ll need to contact customer service at 888-478-0415.

Should You Buy NO2 Maximus?

Chopping to the point: Considering:

  • The lack of clinical evidence supporting any of the manufacturer’s claims,
  • The underhanded marketing tactics they use, and
  • The fact that it’s only sold through a free trial and autoship program,

…it’s our opinion that NO2 Maximus is a scam.
