So you’ve probably heard of Nitraflex at one point if you’ve scoured the internet for a stronger pre-workout…And you saw Nitraflex and thought “well damn, free testosterone? lets f*cking get it!”

My question is, did it work? Did you feel the difference?

German American Technologies AKA GAT has been around for 20 years, which means they should be doing it right… right?

325mg of Caffeine… that’s pretty damn strong.

But what else does Nitraflex have in its formula that makes it one of a kind?

Let’s find out!

What Separates Nitraflex +C From The Rest?

Clinically-Studied Testosterone-Enhancing Complex – Calcium Fructopyranose Borate (CFB)

CFB is a type of ‘Boron’ that decreases Sex Hormone Binding Globulin (SHBG) within your body, which in turn can boost your testosterone.

These effects will come down to your take on placebo, and whether you believe in it, and see for yourself if it makes a difference.

So whether you choose to dismiss this as a Unique ingredient, what else can they bring to the table?

325mg of That Sweet, Sweet Caffeine

Buckle up ladies and gents, because if you’re an avid Coffee drinker, or love Caffeine in general, this will get you buzzing hard.

We can confirm that GAT’s Nitraflex does indeed contain 325mg of Caffeine.

That is about 3.2 cups of Coffee, in 1 scoop…

It is not recommended to take this at night and you should take it at least before 5 pm in the arvo.

But if you’re a long-time pre-workout user, you could take this and sleep like a baby!

GAT’s Nitraflex +C Ingredient Breakdown

L-Citrulline [2-Amino-5-(carbamoylamino)pentanoic acid)]

L-Citrulline is a non-essential amino acid (body produces this naturally)

Citrulline is a popular ingredient in improving blood flow, endurance, muscle growth, and even heart health.

The main uses for it are being able to work out for long periods of time, resistance and endurance.

L-Arginine – [(S)-2-Amino-5-guanidino pentanoic acid]

L-Arginine increases nitric oxide which in turn dilates the blood vessels.

More blood and oxygen passes through your veins, which in turn provides more blood into your muscle that you’re working out

L-Arginine – Alpha-ketoglutarate (AAKG)

AAKG is usually ingested as an intermediate during the citric acid cycle.

During the citric acid cycle, AAKG enters and produces L-Glutamine as well as energy.

Taking L-Arginine AAKG has the same effect as if you were taking Alpha-Ketoglutarate and L-Arginine at the same time.

1.5g of CarnoSyn Beta-Alanine – 3-Aminopropanoic acid (as CarnoSyn)

In general Beta Alanine bonds with some sort of filler that makes it less potent.

The Difference?

CarnoSyn Beta-Alanine is the purest form of Beta-Alanine on the market, making it super potent.

Beta-Alanine is a non-essential amino acid that your liver produces.

You can get more of this through protein-heavy foods, such as chicken, or beef.

Beta Alanine boosts performance, delays fatigue and maintains muscle strength throughout your workouts.

Caffeine [Coffea Robusta (bean)] – 1,3,7-Trimethyl-1H-purine-2,6(3H,7H)-dione

Upon further research, I had found that Nitraflex uses Coffea Robusta, which is a type of Coffee Bean.

Caffeine gives a boost of energy, and is a Thermogenic which helps shred fat.

DMAE – 2-(Dimethylamino) ethanol

DMAE has anti-aging benefits and improves cognitive function.

There is very limited amounts of research done for DMAE, so it’s full effects may be unclear.

N-Acetyl L-Tyrosine – 2-acetylamino-3-(4-hydroxyphenyl)-propanoic acid

So you got the pump, you got the endurance to go harder and longer at the gym, but what about that mental focus though?

N-Acetyl L-Tyrosine is the ingredient for the job.

This specific ingredient affects your Mental Focus and enhances your mood.

It has positive effects by affecting your “feel good” hormone known as dopamine (and others).

Rauwolscine (A Molecule Like Yohimbine) – (Rauvolfia Canescens L. [Leaf And Root])

So Rauwolscine is NOT Yohimbine, but rather a molecule that is very similar in structure to it.

One of the effects of Testosterone is to increase Male libido, which in turn provides a higher sex drive.

Rauwolscine aids in fat burning (not so much fat loss, but the literal burning of fat).

This works by alleviating the pressures of the body exerting energy to preserve fat mass.

There are not enough clinical studies to back Rauwolscine and it’s effects.

Does Nitraflex +C The Ingredients Work Well Together?

GAT’s Nitraflex has boosts your pump, endurance, energy, libido and testosterone…

… according to it’s label.

But how about from personal experience?

The Workout Effectiveness – Pump, Endurance & Mental Focus

The pump formula (L-Citrulline, L-Arginine) all have great dosages designed to last a whole workout.

With the help of a branded Beta-Alanine, this will also help with delaying muscle fatigue, which will increase endurance.

Mental Focus? No worries; N-Acetyl L-Tyrosine provides that Tunnel Vision focus and concentration.

Combined together?

You now have a magical pre-workout blend designed to increase performance, and provide a killer workout.

Mixing In The Caffeine?

Depending on your tolerance, 325mg might come off as a bit much for some people.

If you don’t usually take Stimulants, this will definitely put you on edge, and give you crazy amounts of energy.

The best method to test this is by starting off with 1/2 a scoop and testing your tolerance.

But if you take pre-workout every day, this will be an optimal amount.

What About The Testosterone Booster?

An increase in Testosterone will always help in long-term gains.

But, you will be able to get a much more potent dosage by using pill-formed testosterone boosters.

You can give kudos to GAT for a one of a kind product which has testosterone enhancing abilities.

Although, you will have to test whether you feel a difference yourself.

Upon testing, I definitely did feel a slight increase in aggression, with a definite increase in libido (due to the DMAE as well).

Overall Review

Nitraflex has a great formula, whether you’re chasing the pump, need some mental focus or an energy boost.

It will last you a couple of hours, long enough for you to get a solid 2 – 3 hour working in.

You’re much better off grabbing a separate Testosterone Booster if you’re looking to enhance that.

But, if you’re looking get that slight increase in Test, by all means, go for it.

Overall, it’s a solid mix that has been around for a long time, and if you’re looking to switch pre-workouts, Nitraflex can be your next stop!
