We have reviewed several dozen types of muscle building supplements, creatine supplements, and even HGH supplements. The goal of our site is to provide you with up-to-date, accurate, and unbiased information concerning the effectiveness of these supplements. When we first came across Xtreme NO, we were a bit skeptical that any Nitric Oxide supplement actually worked. We were very new to the technology behind it, and not sure of the scientific explanations these companies were providing.

After some deep research, as well as talking with people who have tried Xtreme NO, we decided to place our own order of Xtreme NO. Our staff tested this particular product for a wide variety of criteria, including:

  • Results Before and After Workouts
  • Any Side Effects
  • Size Gains
  • Fat Loss
  • Energy Levels

What Were Our Results?

xtreme no reviewAfter taking Xtreme NO for approximately 3 months, I noticed a significant amount of lean muscle gain when compared to a placebo. The biggest difference was in my size gains, allowing me to gain inches both in our arms, legs, and chest.What was even better was the increase in energy I felt after taking it for so long. My workouts had become that much more effective, and I was not getting as tired in the gym.

I also had lost about 10 pounds of fat, making me shredded beyond what I ever imagined. There was also the added benefit of increasing my sex drive, which apparently is a by product of Nitric Oxide production. In fact I was so happy with my results, that I ended up purchasing another 6 months supply of Xtreme No.

Reviews from other people we found:

“I have tried alot of different muscle building products, and the results were up and down. When I took creatine I would get real big and bulky, but almost looked a little fat. When I took an hgh supplement or a fat burner, I would shrivel up into nothing. Xtreme NO was great because it allowed me to build lean muscle and burn fat at the same time.”
Mike, New Jersey

“They say that all NO supplements are the same, but thats total bs. I used products like Ripfire and Muscle Warfare Napalm, and if it did work, I would get the worst side effects from it. Nothing turns me off a product quicker than getting nausea and feeling sick all day after taking it. I didn’t feel that way when I took Xtreme NO, and it worked wonders for my gym routine. I noticed a big difference in my ability to stay in the gym longer, and as a result I ended up getting Jacked really quick. Well worth the price in my book.”
Jeff, Nevada

Questions We’ve Received About Extreme NO

Q.You have mentioned you had good results from both the above products (Nitrocut and Xtreme NO).

However do you think one is significantly better than the other?

I have tried Nitrocut with good results a few months ago.

Second time around I was wondering if I should try Xtreme NO – also since it has a prolonged release system as well as is about 25% cheaper than Nitrocut. (KS, email received March 24, 2014)

A.Thanks for your email.

In my experience, both Nitrocut and Xtreme NO will give you great results, so really it comes down to personal preference.

I get pumps, energy, and stamina from both.

My personal preference is for Nitrocut, but I certainly can’t argue with the price break you get with Xtreme NO.

What are the ingredients?

Xtreme NO is made up of 3 high-quality variations of L-Arginine, including L-Arginine Hydrochloride, L-Arginine alpha-ketoglutarate, and L-Arginine ketoisocaproate, as well as an advanced nutrient delivery system that includes L-citruline, dipottasium phosphate, dicalcium phosphate, and nicotinamide adenine dinucleotide.

How do i take it?

The directions on the label state that you should take 2 tablets 30 – 60 minutes prior to a workout on an empty stomach. For me it seemed to take a bit longer to kick in, so I would recommend you take it at least 45 – 90 minutes prior to a workout, and combine it with caffeine for an added kick.

How long does it take to start seeing results?

Generally speaking, you should start feeling the effects within the first few days. For me, that meant a more “veiny” appearance after a workout, the ability to last longer during workouts, and a sculpted / more muscular physique.

You can expect the higher energy levels, fat loss, and bigger muscle gains in about 2 – 3 weeks, along with a rigorous training regiment.

I recommend you signup for my free “How to get Ripped Quick” ebook and use it in conjunction with Extreme NO for the best results.

Are there any side effects?

I personally did not experience any side effects with Xtreme NO. With that said, it’s always a possibility. One thing I will note is that if you are taking any blood pressure lowering medications, it might not be a good idea to take this.

Because it contains L-Arginine, and l-arginine causes your blood vessels / arteries to widen, it may cause your blood pressure to drop too low. Other then that I don’t see any other interactions, but of course it’s best to speak with your doctor to be sure.

Where To Buy Extreme NO

As of this review, you can only buy Xtreme NO from their official site. They offer a number of discounts if you buy in larger quantities, with a 6 months supply coming in at just $25 a bottle. We recommend that you order the six months supply to get the best results from this NO supplement.

As of this review they do NOT sell Xtreme NO is stores like GNC, Vitamin Shoppe, Walmart, etc. You’re stuck with ordering it online.

Also, despite people telling you that they have a free trial / sample, this is simply not the case. They do, however, offer free bottles when you order larger quantities. For example, if you buy a 3 month supply you get 3 additional bottles, and if you buy a 2 month supply you get 1 free bottle.


So why did I rank this as my #3 pre workout supplement? Well as you can see from the my results section above, it’s a very effective product that pretty much does what it says it does. However, it’s not some revolutionary pre workout supplement…it contains many of the same ingredients found in dozens of other brands.

HOWEVER, the difference is that you can get an UNLIMITED lifetime supply of Extreme NO when you checkout with your original order. Let me explain…

When you go to checkout on their official website, you are prompted to put in your details (name, address, email, etc.). If you select the one month supply (which is only $39.95), input your credit card details, and click “Submit Order”, you are THEN taken to a special offer page which allows you to signup for their unlimited refill program at a cost of $49.95, which does NOT include monthly charges and is NOT an auto-rebill, auto-shipment program.

This essentially means that EVERY 30 days you can request another 30 day supply of Extreme NO, and pay ONLY $16.97 for shipping. This is an absolute GEM that I completely missed the first time I bought Extreme NO.

Essentially, you will be getting a new bottle of this stuff every 30 days and only pay $17! This literally makes it the CHEAPEST pre workout supplement you will find on the market.
