GAT Nitraflex Review - 11 Things You Need to Know

GAT Nitraflex is a “clinically tested, high-intensity pre-training formula with potent ingredients to help magnify energy, alertness, strength, stamina, pumps and enhance testosterone during workouts.” The company claims that its supplement, which is said to boost athletic performance if taken a right before a workout, has been clinically-tested. While we found clinical studies on beta-alanine ingredients, we could not find any clinical trials connected to Nitraflex itself.

So, we put our team of researchers on the job, asking them to dig into GAT Nitraflex’s ingredients, potential side effects, scientific studies, and all available user comments and reviews.  We then condensed this information to give you the Bottom Line on the product.

What is GAT Nitraflex?

The GAT Nitraflex is a dietary supplement to be consumed before working out. It is supposed to promote hyperemia, better blood irrigation in the body, and enhance testosterone availability. Apparently, this results in increasing energy, awareness, strength, stamina, and even sexual performance, but do the ingredients actually work as claimed? Let’s look briefly at citrulline, l-arginine and beta-alanine.

  • Clinical Nutrition – “The amino acid L-citrulline (CIT) is safely used from the neonatal period onwards in those with urea cycle defects and carbamyl phosphate synthetase or ornithine transcarbamylase deficiencies, but several lines of enquiry indicate that it might have a much wider therapeutic role.”
  • PLoS One – There’s also evidence that the combination of citrulline and l-arginine works to support heart health. “L-citrulline and L-arginine supplementation has been shown to have several beneficial effects on the cardiovascular system.”
  • Frontiers in Physiology – As for beta-alanine, there’s a plethora of research showing how this ingredient can improve exercise performance.

What Is GAT Nitraflex?

This supplement is in the form of a powder to be drunk diluted in cold water, half an hour before you begin your exercise routine. It is available in several different flavors, such as:

  • Blue Raspberry
  • Black Cherry
  • Green Apple
  • Watermelon
  • Fruit Punch
  • Orange
  • Grape
  • Beach Blast
  • Blood Orange
  • Blackberry Lemonade

How Did GAT Nitraflex Start?

GAT Sports was established in 2012. They offer products to health enthusiasts that wish to boost their physical performance during their daily work out.

While this product may be used on its own, GAT Sports takes pride in advertising its whole family of merchandise as highly complementary. This means you could use it stacked along with other company products to restructure further aspects of your health and mental and physical performance.

Other products in the GAT Nitraflex line include:

  • Nitraflex Pre-Workout
  • Nitraflex Pump
  • Nitraflex +C
  • Nitraflex Burn
  • Agmatine
  • PMP

GAT Nitraflex Claim

According to the manufacturer, this powder will give you the kind of nutrition you need to boost your mental and physical wellbeing. This may allow you to be more active and take better advantage of your workout sessions.

The supplement works by giving you a formula rich in amino acids and other micronutrients, vitamins, and caffeine.

A very bold claim by the manufacturer is that GAT Nitraflex is a clinically tested product. This is highly unlikely for dietary supplements, and they offer no documentation to back up their claim in the form of peer-reviewed clinical trials or studies.

This statement is suspicious, and until the manufacturer provides some scientific evidence, it should not be taken too seriously.

One further claim is about the GAT Nitraflex drug test, which says that if you are a serious athlete using this resource to improve your performance, none of the formula’s chemicals will cause you to fail a doping test.


GAT Nitraflex Ingredients

The GAT Nitraflex ingredients list is not too long. Some of the components are just micronutrients. Ingredients include:

  • Vasoactive Arginase-Regulating NO Precursor Complex: Citrulline, Citrulline Malate, L-Arginine Malate, L-Arginine Alpha-Ketoglutarate, Resveratrol, Nitrosigine, and Pterostilbene.
  • Acute Energy, Focus, Intensity, Neuromodulating, Endurance Complex: Beta-Alanine, Caffeine, DMAE Bitartrate, N-Acetyl L-Tyrosine, Theanine, Raulwolfia Canescenes, and Nitrosigine.
  • Clinically-Studied Testosterone-Enhancing Complex: Calcium Fructoborate and Nitrosigine.

To understand the possible benefit and side effects of this product, let’s take a closer look at the most relevant components in the list in some detail.

L-Citrulline Deanol

This is a chemical known as a non-essential amino acid. It is transformed into l-arginine and nitric oxide in the body.

It’s considered to be important for health and vascular health in general. Nitric oxide can relax your arteries and improve your overall blood flow.


Boron, most commonly in the form of boric acid, is an important mineral for the human body. It seems to enhance how the body handles other important minerals, like phosphorus, magnesium, and calcium.

GAT Nitraflex Ingredients

It is used to build strong bones, increase testosterone, improve muscle coordination and thinking skills, and treat vaginal yeast infections.


Caffeine is most popular as a stimulant for the brain as it improves mental alertness. However, it also has many other uses in combination with painkillers.

It is widely used for weight loss. It is cheap and legal to consume everywhere, particularly in hot coffee or hot tea.


So far, however, no definitive evidence has been found to support the claim that Resveratrol may help improve or prevent any health condition in humans.

Weight Loss

GAT Nitraflex And Weight Loss

Any GAT Nitraflex review on bodybuilding will tell you that this is a product that is not marketed as a weight-loss supplement or pill. That is not what it promises, and you should not expect those extra pounds to go away by including this in your diet.

This product does make several other promises, such as increasing your testosterone, physical and mental energy, and overall well-being. This may make it easier for you to start exercising more and eat better.


How To Use (Take) GAT Nitraflex?

The correct way to take advantage of GAT Nitraflex is effortless and straightforward.

You are supposed to take a scoop of the powder and dissolve it in 10 ounces of water and drink it thirty minutes before starting with your daily workout routine.

Even in days that do not include engaging in a workout, you should still take the same amount of GAT Nitraflex in the morning with water.

Side Effects

GAT Nitraflex Side Effects

To understand the GAT Nitraflex pre-workout side effects correctly, we need to review the GAT Nitraflex ingredients and the side effects that are commonly associated with each ingredient.

GAT Nitraflex Side Effects

In some GAT Nitraflex testosterone reviews, users have reported anxiety, irritability, sweating, nervousness, insomnia, and nausea by ingesting this product.


Boron is considered safe when taken in the proper amounts needed daily by the body (20mg). However, since estrogens have action, it should be avoided by people suffering from health conditions sensitive to hormonal imbalance and those suffering from any kidney problems.


There are no side-effects associated with Resveratrol, but research is still lacking.


As stated before, the body produces its own arginine normally, and most people have enough of it already. This means it’s a naturally occurring substance that is considered very safe, even in supplementation. Side effects of this ingredient are rare, but they could produce diarrhea, nausea, and cramps.

Product Warnings

GAT Nitraflex Product Warnings

The manufacturer provides with several warnings about this product’s use. These include:

  • Intended strictly for people over 18 years of age.
  • Every scoop (a single serving) has 325mg of caffeine in it, so this should not be taken along with other caffeine products or stimulants.
  • Not to be taken during pregnancy or nursing.
  • Do not ingest along with anti-inflammatory drugs or aspirin.
  • Rest for a full week from ingesting this product after having completed eight weeks of consumption.
  • Discontinue using this product at least two weeks before any surgical procedure.

GAT Nitraflex Product Warnings

While most of these warnings are more or less the standard warnings required by the law to be included with this kind of product, it is still good to see that the manufacturer tries to make the prospective user aware of the high amount of caffeine present in the supplement.

Although GAT Nitraflex does not contain caffeine anhydrous, excessive amounts of caffeine can still be harmful.

According to one study published in StatPearls, excessive caffeine consumption may lead to increased urination, anxiety, gastrointestinal distress, restlessness, and increased heart rate.

    Fahim (Verified Purchase)

    Good supplement for pre workout…

  • Joe Rec (Verified Purchase)

    Been using nitra flex since 2014, taste isn’t the best but it’s a preworkout, I’m not drinking it to quench my thirst. Works great definitely maximized my strength, great pump, but you have to cycle off after a while you’ll build a tolerance as your body does with anything that becomes routine. I limit my caffeine intake daily so that I feel the full effect of nitraflex. Helps when I’m studying too. Very very focused.
