It’s no secret that our team at Total Shape is a big fan of dietary supplements, but pre-workout supplements are among our favorites.

Just because supplements claim to boost your strength, performance, and muscle growth doesn’t mean they actually do. And in our experience, there are more weight loss and workout supplements that don’t work than those that do.

When we see claims of “endless energy” and “powerful pumps,” we get even more suspicious and go through some extensive research and testing.

So, we got ten clients to help test Nitrosurge and a nutritionist to research all the ingredients.

What Is Nitrosurge Pre-Workout?

Nitrosurge Pre-workout is a supplement manufactured by Jacked Factory. It is designed to increase strength, boost muscular endurance, and reduce fatigue. With science-backed ingredients like L-citrulline, beta-alanine, and L-theanine, it also delivers a nitric oxide boost for increased blood flow and more intense pumps.

There are also claims of near-instant boosts of energy, and that’s where we started to get a bit concerned about whether Jacked Factory has spent more money on clever marketing than research.

Our #1 Recommendation

Nitrosurge Benefits

The first thing we noticed is that quite a few of our testers commented that they felt fatigue didn’t set in as early as normal.

This is most likely due to the caffeine, l-theanine, and beta-alanine mix that Jacked Factory has formulated.

Now, let me tell you about another important factor, and that’s the powder itself. So many supplements require a shaker or blender to avoid clumping. But, in our experience, Nitrosurge mixes easily with water.

And the flavors are not too sweet or overpowering, with my favorite being the cherry limeade flavor. So, thumbs up for the Nitrosurge taste.


Does Nitrosurge Have Any Downsides?

Nitrosurge has a few downsides relating to its efficacy. We stuck with the recommended dose of one scoop, and we didn't find a measurable difference in pumps. I also didn't experience any energy boost and improved focus while using it.

I had the rest of the team test it out with two scoops to see if they got an extra boost of pumps, but the results were limited as well.

We also saw that a few users complained about a tingling sensation. This isn't uncommon with pre-workouts, but normally this doesn't last as long as what users have reported.

  • Seems to work OK to reduce fatigue due to beta-alanine and l-theanine dose
  • Easy to mix powder makes adjusting the dose a lot easier
  • Natural and artificial flavors from fruit and vegetable juice
  • Contains quite a strong dose of caffeine that could mess up your sleep
  • Doesn’t quite maximize blood flow like other supplements
  • Some reports of a tingling feeling that lasts for a few hours

Nitrosurge Ingredients

Supplement facts of Nitrosurge

Here are the other ingredients not already mentioned that the company has chosen for this pre-workout.

Beta-Alanine- This is the main ingredient that should support the claim that Nitrosurge may reduce symptoms of fatigue. And my own experience does support that, along with the tingling feeling that would be normal.

“Beta-alanine is a non-essential amino acid that is produced naturally in the body. Beta-alanine aids in the production of carnosine. That's a compound that plays a role in muscle endurance in high-intensity exercise.”

- Matt McMillen, Writer at

Caffeine Anhydrous- Caffeine is a great stimulant to trigger thermogenesis and fat loss but also great for providing mental focus during a tough workout.

L-Citrulline- Studies from the Pennington Biomedical Research Center have shown that l-citrulline may boost nitric oxide levels [1], but it seems like it doesn't have effective doses per serving.

L-Theanine- This is an amino acid that may help to improve mental focus and physical stamina [2].

Betaine Anhydrous- Some people say that betaine anhydrous may help with water retention in muscles, but scientific studies have been inconclusive, showing limited effects.

Theobromine- This is another questionable ingredient because of a lack of evidence. There might be a link to appetite suppression, but that’s not what you need for a pre-workout.

AstraGin- This is a blend of Astragalus root and Ginseng, and again, we couldn't find enough evidence to support these as some secret to improved pumps.

How Does Nitrosurge Pre-Workout Compare To Other Supplements?

Different supplement products on a white background

Let’s look at how Nitrosurge Pre-Workout performs against three leading pre-workout supplements.

Gorilla Mode

Based on my personal experience, Gorilla Mode is an effective pre-workout supplement created by the well-known nootropic Gorilla Mind Rush makers.

This supplement is loaded with essential ingredients such as L-citrulline, creatine monohydrate, and betaine, which are proven to increase nitric oxide levels, giving you an extra boost during your workout. Our test group can attest to this benefit.

Additionally, Gorilla Mode is easy to mix and fast-acting, making it preferred by our testers. You get a 15.245-gram serving with just one scoop compared to Nitrosurge’s 9.3 grams. You’ll also get more L-citrulline than Nitrosurge at 4500 mg versus 3000 mg.

Both supplements have comparable amounts of betaine anhydrous and have manageable caffeine anhydrous content that didn’t produce any adverse effects in our test group yet gave ample energy.

4 Gauge

The pre-workout 4 Gauge is a collaboration between the manufacturer, dietitians, nutritionists, and athletes.

Our trial users reported impressive results with increased focus and energy, particularly during intense workout sessions.

I noticed right away that 4 Gauge contains twice the L-citrulline at 6000 mg than Nitrosurge, a significant difference in getting those muscle pumps.

Nitrosurge and 4 Gauge use caffeine and L-theanine, a combination that gives me increased energy and focus throughout the day without any side effects.

Unlike Nitrosurge, beta-alanine is excluded from 4 Gauge’s formula, so our test group didn’t experience tingling, which is often a side effect.

Transparent Labs

Transparent Labs PreSeries Bulk promises to boost your muscle mass growth, energy levels, and endurance, and with 6000 mg of Citrulline, twice as much as NitroSurge, it seems to deliver results.

Our test group reported that PreSeries Bulk mixes perfectly without clumping and incredibly boosts focus and energy. We ordered a few different flavors for testing, but the consensus was the strawberry lemonade was the best.

NitroSurge and PreSeries Bulk contain 180 mg of caffeine and L-theanine, but Transparent Labs has 200 mg versus Nitrosurge’s 90 mg.

Where Can You Buy It?

You buy Nitrosurge from the official company website.

As far as delivery goes, we ordered this product twice, and delivery times varied a lot. Once, it took three days, and the second time it was over a week, which isn’t great.

Even so, never buy the product from other platforms since you're putting yourself at risk of getting a fake or expired product. It's better to wait long for a legitimate delivery since you'll harness the full Nitrosurge benefits.

Nitrosurge Pre-Workout User Reviews

We also took a look at online reviews to see if the responses were similar to our experience.

He took this pre-workout and, after 30 minutes, felt a very strong tingling feeling and even a feeling of anxiety. He did take advantage of a full refund under the money-back guarantee and would caution against taking it.

- Travis, Florida

Sean said that it tastes great, which we agree with, but he just didn’t get the maximum pump he’d hoped for. He also pointed out that it did give him some laser focus to stay on track at the gym.

How About The Bioavailability of Ingredients?

Bioavailability is crucial in determining the effectiveness of supplements like Nitrosurge. It refers to how well the body can absorb and use its ingredients, such as amino acids and caffeine.

While Nitrosurge contains beneficial components, our test results suggest that other products may offer better bioavailability, leading to more efficient absorption and enhanced results. Understanding this can guide consumers in choosing the most effective supplement for their fitness goals.

Impact on Mental Focus and Cognitive Function

Nitrosurge aims to enhance not just physical performance but also mental focus and cognitive function during workouts.

However, comparative analyses based on our test results indicate that alternative products may offer superior benefits in these areas.

While Nitrosurge contains ingredients intended to boost concentration and mental clarity, its impact might be less pronounced compared to other specialized supplements like Gorilla Mode, which is explicitly designed to enhance cognitive performance alongside physical endurance.


Does Nitrosurge Contain Stimulants?

Yes, Nitrosurge contains stimulants in the form of caffeine. It's a common ingredient in pre-workout products because it helps keep the mind focused.

Just don't take this product later in the day to avoid messing up your sleep.

When Should You Take Nitrosurge?

You should take Nitrosurge about 30 minutes before you work out. That should give your body enough time to absorb and activate certain ingredients in time for the more challenging parts of your workout.

Our Verdict on Nitrosurge

Based on our research and testing, we’ve come to the conclusion that we wouldn't recommend this pre-workout supplement.

The results just don’t quite match up with the marketing statements.

We’ve seen far better results with Gorilla Mode, and even my workout partner asked what had happened when I first started taking it.

It's great for long-term use, and having assessed over a dozen of my clients to transform their health and fitness with Gorilla Mode, I make this a priority for many of my friends and family as well.

We Recommend This Instead

Is This Pre-Workout Worth It?

  1. I’ve been using pre-workouts for 10 years now and have tried all the best brands. I’m not exaggerating when I say that Nitrosurge is the best pre-workout on the market. The energy is powerful without being too much, you don’t feel jittery, and there’s no crash.

  2. I’ve been using this for about a month now; it has very few negative effects and works quite well. I especially like the pump it provides.

  3. I’ve been using Nitrosurge for months and it definitely delivers the power I expect during my workouts. No scam here.
