Does It Really Increase Your Size
User Reviews

Nitroxin is a male enhancement supplement based on the principle that nitric oxide will help you get the best erections possible, thereby increasing your size and improving your overall sex life. This product is marketed and sold through its official website, where it is touted as being backed, created, and used by famous porn stars, including Bree Olson.

The claim is that when you use Nitroxin, you’ll gain a permanent 2.9 inches in penis length and a significant, though unspecified increase in girth as well. Another potential benefit of taking Nitroxin is the confidence that comes along with having a bigger penis and knowing how to use it.  But can they really back up these claims with solid proof?  Let’s take a look at the supplement in more detail.

So What’s The Deal With Nitroxin?

After doing a bit of research, I noticed that they promote Nitroxin as sort of a double edged sword.  They have the pill, which seems to be positioned as an alternative to viagra, and then they have a cream, which I’m guessing you’re supposed to rub in just prior to sex.

The official website mentions 4 primary ingredients; Oyster shell extract/zinc, Horny Goat Weed, Muira Puama, and Maca.  It’s pretty well known that Horny Goat weed can be found in numerous other male enhancement supplements, which leads us to question why they promote this as a “revolutionary” formula.  What I also find a little confusing is why they don’t mention on their site that it contains L-Arginine, even though it clearly does.

Nitroxin ReviewFinding info on the cream was a bit scarce.  My guess is that it also contains the same ingredients, but that because its applied in cream form it’s supposed to help it work faster.  They go on to say that, in a recent poll, 87% of women say bigger is better.  No s$#t Sherlock!  They also show a graph of a study that shows a correlation between the size of a man’s penis, and the number of sexual partners he has.  This one I’m not so sure I agree on.

They also mention that they had an “Expert” research for many hours to develop the formula, but fail to mention the name of this supposed expert.  It’s not mentioned how you should take Nitroxin on their official site, but we do know that you are supposed to take a dose everyday to see the best results.

So What Are Guys Saying About It?

The only reviews I could find were on the companies official website.  “Douglas”, who hails from Ohio, said that he gained 1.5 inches in just 2 weeks, and after 3 months he is a total of 7 inches long.  “Laura”, said that her husband gained 2.5 inches, and they now have sex 5 times a week.  Thanks for the visual Laura…You can also see a “review” from a woman who go’s by the name of Jully Star, who posted a video review that said Nitroxin actually saved her marriage.  Check it out below:

Now, I don’t know about you, but something about this “review” seems scripted.  She’s scantly clad in a bra, and looks fairly attractive, but something just doesn’t seem right.  In the first half of the video, but right around the 20 second mark she starts looking up, like she’s reading off a script card.  She talks about how her husband has regained his sexual prowess, and even how much more confidence he has.  But where the hell is the husband?  I don’t know about you, but I would rather hear from the horses mouth, then this likely paid reviewer.

The reviews on the BBB website, however, paint a very different picture.  Over the last 12 months, Nitroxin has received a whopping 37 complaints, and achieved the rating of F.  Not something you should be shooting for if you have a well known and highly regarded supplement.

Things on don’t look much better, with 4 consumers complaining they had been unfairly charged for the product when they didn’t want it.  On top of that, they mention that they didn’t even get the desired results from the product.  I’m also seeing evidence that the company routinely sends out junk email blasts to former customers trying to order more product.  Who would have thought based on their reputation?

A simple fix to this would be to setup a spam filter with your gmail, yahoo, or other email address.  That will put a stop to them once and for all.

Lastly, there is some blog out there that says if you combine Nitroxin and Testorush, the results will be even better.  It’s a load of BS, and you’ll find out why later on in this review.

Are there any side effects?

nitroxin side effectsThe product site boasts that there are no side effects from taking Nitroxin, but I beg to differ on that one.  For instance, taking Horny goat weed for a long duration has proven to cause numerous side effects, including dizziness, dry mouth, constipation, and vomiting. (1)  Muira puama, another primary ingredient in Nitroxin, has been shown to cause insomnia in some people.

And god knows what’s in the cream version, and I’m willing to bet that some guys would probably get a rash, blisters, or other allergic reaction from it.

Nitroxin Pros and Cons

Knowing that there’s good and bad in everything, we always like to list them out. It helps when we’re coming to a decision about whether or not to recommend Nitroxin or any other product.


  • The ingredients are claimed to be all natural.
  • There is a money back guarantee.


  • There are no clinical studies cited regarding its effectiveness.
  • We found some Nitroxin reviews complaining about the poor customer service provided by the company after the sale.
  • Nitroxin makes the empty promise of permanent size increases.
  • Not available in stores like GNC, Walmart, or other retailers.
  • Only available in the US

Where Can You Buy It?

nitroxin scamYou can purchase Nitroxin online through the official website, and at this time the only way it is available is by signing up for their free trial.  You should be VERY cautious of this because after 14 days of ordering you will be charged a whopping $89.95 for both the pills and the cream.  It’s not a free sample like the advertising would like you to believe.  On top of that, they end up charging your card this very same amount MONTH after MONTH until you cancel.  If your having trouble finding the phone number to cancel your trial, here is their customer service number: 1-800-361-5009

Some guys end up spending $100’s before they realized they’ve been duped by this scam.  They offer a supposed “30 day money back guarantee”, but there’s one major issue with this…you have to return the unopened box in order to qualify.  Do you think there are alot of guys out there that didn’t open the bottle up?  That’s right, very unlikely.  You can learn how to protect yourself in the future from these scams in our free “Supplement Scams Exposed” report.

As far as I can tell Nitroxin is not available in countries like the UK, Australia, and Canada, however there may be some individuals selling their “leftover” bottles on ebay and other auction sites.

So Does It Really Increase Your Size?

We’ve come across alot of supplements that make this claim, and it’s probably the most common question I get as well.  Even though I haven’t actually had a chance to try Nitroxin yet, I can say with relative certainty that it probably does NOT increase the size of your penis.  There is no supplement that will do this, despite the claims of many of these manufacturers that it will.

You see, what most of them don’t want you to know is that size gains are all about blood flow.  The penis is sort of like a balloon.  When the 2 penile chambers called the corpora cavernosa fill with blood, your penis becomes erect.  Once you climax, the blood rushes out and the penis returns to it’s normal flaccid size.  There is no permanent gain from this, if that were the case we’d all be walking around hung like horses.

The only thing I might add is you MIGHT (and I say that cautiously) be able to gain some size if you use the cream in conjunction with enlargement exercise routines like jelqing and milking.  However, the only REAL benefit would be the fact that you’re using a lube to make the exercising more efficient, and any size gains you would see would be from the exercises themselves, not the Nitroxin cream.


As is the case with a lot of male enhancement supplements, Nitroxin is more about marketing than anything else. In this case, they use porn stars and permanent penis growth to lure you in.

Well, I have got some news for you that you may not like to hear but in all honesty, you need to hear it; there is without a doubt zero male enhancement supplements currently in existence or anywhere in the foreseeable future that can actually give a man any amount of permanent size gains in their penis, period.

Don’t be fooled.  They are simply trying to trick you into believing your getting a free sample of their product when indeed they are intending to suck you into an auto billing nightmare.

  1. Rob I think you need to put a giant red and bold font disclaimer at the top and bottom of every page. They’ve all been hurt in the worst way by that company, financially, criminally, pride, self-esteem, and trust.

    You combine all of those into a single individual mind and it strips all their ability to think with any rationale and logic.
    If you care about what has happened to them and I believe you do, push PayPal furiously to protect them.

    I opened an account after getting screwed and they’ve saved me several times since! With PayPal it doesn’t what payment method you used with the seller, ALL recurring payments are in a separate section.

    Every business you are allowing to debt your bank account, credit card, PayPal account, whatever, has a link beside their name for you to either suspend future payments or cancel them! You don’t rely on all those crooks out there to suddenly feel sorry for what they’re doing and stop.

    Hell No! Login, go to their name and click Cancel Recurring Payments!!!

    My god what a life saver!
    That’s what I would tell all these guys and I’m sorry this is so long.

    1. Hey Norman,

      It looks like their only customer service is over the phone. Here’s their number: 1-800-361-5009.

  2. Ordered and cancelled the same night and was charged 89.00 and I mean within an hour, do not play with these people of this product, never used nor intend on using.
  3. I couldnt help but notice you stated in this review “that it probably does NOT increase the size of your penis there is no supplement that will do this, despite the claims of many of these manufacturers that it will." Yet your #1 choice is Vigrx Plus? Isnt that a bit contradicting?

    This site like many others seems fishy to me like you have a deal made with vigrx plus or something
    1. Hey B,

      It is true that no supplement will make your penis bigger. But VigRx Plus (along with hundreds of other products) is a sexual performance enhancement supplement. It doesn’t claim to make your penis bigger. It claims to help you get better erections and increase your libido and stamina. I do have an affiliate arrangement with VigRx Plus, but of all the products I’ve tested, it’s the best I’ve found. Hope that helps clear things up.

  4. I ordered this product in may. Ad said with discount for trial bottle would be $2.95 for shipping and handling. yet the person I spoke to told me it was $4.95 and they billed me twice once for the $2.95 and for then for $4.95, I called to canceled on June 2 and asked if I would be charged for this, they told me NO.
    Now 2 months later I am being charged $4.95 which they say is half price because there wasn’t enough money in my account to cover the full cost. 2 months June and July and there wasn’t enough in my account?

    And this after I had cancelled in June. I want my money back.

    What you did was steal from me. Ive called 3 times twice the reps. hung up on me.

    Third time I called I got the same rep. Now if this is how you do business be prepared to get bad word of mouth about your practices and your product.

    Because it Does Not Work. Refund my money all of it.

    1. Hey Leroy,

      Sorry about all the trouble you’ve been going through, but we are a review site, and we warn against signing up for these bogus free trials. As far as I can tell, Nitroxin is one of the worst.

      My best suggestion is that you cancel your credit number and get a new one. Your credit card company should be able to help you out with this.

  5. I want to cancel nitroxin There is no free trail after 2 weeks I was charged $89.95 for a 30 day supply & some cream that isn’t all that!!!!
    1. Hey James,

      You’ll have to call Nitroxin and cancel future orders if you don’t want to keep being charged monthly. Their number is 800-361-5009.

      This kind of free trial scam is getting more and more common, and lots of guys are getting caught up in it.

    1. Hey Alejandro,

      Looks like you ordered a free trial of Nitroxin. We are a review site and don’t sell products, and we don’t even recommend Nitroxin.

      The customer service number I found on their website is 1-800-361-5009. You’ll need to contact them to cancel your order.

    1. Hey Javaris,

      Sounds like you signed up for a free trial of Nitroxin and you got signed up for their autodelivery program. We don’t sell or distribute products, and we don’t recommend Nitroxin.

      You’ll have to call the company directly to cancel your deliveries. The number I got from their website is 1-800-361-5009.

    1. Guys, please read the review. We don’t own Nitroxin or sell it, we simply wrote a review.

      In fact, in this review which it doesn’t look like you bothered to read, we specifically mention to NOT order the free trial because of their deceptive billing practices. Scroll up and you’ll see what i’m talking about.
