Nugenix Review: Nugenix Testosterone Booster

Robert Bergen
Medically reviewed by Kimberly Langdon M.D.| 0 Comments

Do you have an inkling that your testosterone levels in the body are low due to stress or lack of sleep? 

When it happens, you may experience slow muscle growth, erectile dysfunction and lagging energy, to name a few side effects. You’re probably here because you’re facing one of these issues, if not more, and Nugenix is a company that aims to help in this circumstance.

It manufactures a wide range of testosterone boosters with purported health benefits for your body. Each product contains various vitamins and ingredients to support you.


Before running out and buying a jar, it’s important you understand what each product has to offer, what the ingredients are and if there are any side effects. Knowing how these supplements compare to others on the market can help you make an educated purchase.

What Is Nugenix?

This company has a man to man focus, providing testosterone boosting products for the men that need them most. It’s possible that those who suffer from low testosterone levels and the side effects of that, such as poor sexual performance, could benefit from a Nugenix product.

But you need to know more about the supplements first and what the customers have to say. Do these products really work? On the company website, you’ll find ample positivity from individuals who supposedly consume Nugenix supplements for muscle mass, low sex drive and more. 

We must tell you, however, that at least one of the Nugenix supplements, the Free Nugenix Testosterone Booster (mentioned below), isn’t FDA-approved [1]. Furthermore, on the company’s site itself, it does state that the statements within aren’t evaluated by the FDA.

This leads us to believe that one should remain cautiously optimistic about the health benefits before going all-out and purchasing the entire product line for low testosterone or t levels.

Why Nugenix Products Have So Many Negative Customer Reviews


Outside of the company’s website, however, user reviews are mixed on the Nugenix supplement line. Negative reviews from people include, but are not limited to, the following complaints, based on original TV recommendations:


  • Little-to-no impact
  • Racing heart rate
  • Paranoia
  • High blood pressure
  • Nausea
  • Poor customer service
  • Waste of money
  • High cost


With this said, other customers have similar reviews to what you’d find on the company’s website. For some, they felt Nugenix did increase testosterone levels by means of better energy, fitness, healthy immune system, and sexual function.

T boosters run the gamut from excellent to very poor and it’s up to the user to determine which works best and what alternatives exist. We briefly review them here in a transparent fashion with details and discuss what each supplement has to offer, in comparison to others available.

Popular Nugenix Testosterone Boosters and Better Alternatives

Nugenix offers five primary supplement lines for different needs. However, they all have one thing in common: they’re made to boost testosterone.

TestoGen vs Nugenix Free Testosterone Booster

Let’s first look at what these products have in common: Vitamin B6, Zinc, and Fenugreek Extract.


All three of these ingredients are commonly placed in T boosters. Vitamin B6 for immunity, Zinc and Fenugreek for increasing testosterone levels in the body [2], [3], [4]. With each item, they come in higher doses in TestoGen, than they do in the Free Testosterone Booster.


Other differences? The Nugenix Testosterone Booster includes Tribulus Terrestris, a well known T level enhancer [5].

However, TestoGen takes it to the next level with several other natural substances including Magnesium, which is a natural relaxant that helps in the muscle repair process [6]. There’s also Korean Red Ginseng and Black Pepper extract included, to name a few.


TestoGen is FDA-approved and as we’ve already mentioned, the Nugenix Free Testosterone Booster isn’t. Furthermore, TestoGen lists a clear substance list with doses directly on its packaging. The Free Booster features only a few as such.

TestoMax vs Nugenix Total-T

TestoMax prides itself on the research that went into making these T level capsules. It has very little in common with Total-T, aside from the inclusion of Fenugreek, Zinc, and Vitamin B12. The latter is included because a deficiency in B12, which supports red blood cells production, is linked to low T levels [7].

TestoMax is full of other nutrients including Folic Acid and Ginseng. Where Folic Acid may affect sperm production, Ginseng boosts immunity and energy levels [8], [9].

Total-T offers more Fenugreek than TestoMax does and some trace minerals of Peat and Apple Extracts, which may enhance strength [10].

TestoMax is manufactured under FDA-approved conditions, while we’re unsure of the approval for Total-T.


HunterTest vs Nugenix Ultimate

HunterTest is one of three T level boosters provided by the Roar Ambition manufacturer. It features three main ingredients including D Aspartic Acid, Vitamin D3, and Indole 3 Carbinol.

While D Aspartic Acid, an amino acid, and Vitamin D3 are common placement, Indole 3 Carbinol stands out here. It might help increase testosterone levels, as shown in studies [11].

Nugenix Ultimate comes with multiple, not-so-well-known extracts including Stinging Nettle, Maca and Boron. The benefits of Stinging Nettle are unclear, it’s the same with Maca, although both of these come with claims that they support testosterone production and sperm mobility.


Where the Ultimate supplement shines is in the dosing of D Aspartic Acid and Fenugreek, at 3000 mg and 700 mg, respectively. This is high compared to many others on the market.


HunterTest is manufactured under FDA-approved conditions.


TestoFuel vs Nugenix Maxx

Maxx is the company’s most comprehensive T booster. It features many of the same vitamins and nutrients found in the supplements above including Zinc, Fenugreek, Maca, Vitamin D, Black Pepper Extract, Ginseng, and more.


It stands out for its inclusion of Ashwagandha at 600mg. Studies show that this root increases energy and libido levels, natural testosterone, and lowers stress to boot [12]

Ashwagandha is a powerhouse of a supplement on its own and has been used for many decades for these reasons.


While TestoFuel doesn’t contain this herbal remedy, it does feature another potent ingredient: Oyster Extract. Many people have long considered oyster meat to be an aphrodisiac. It’s full of Vitamin D, Zinc and Iron, as well. An increase in libido and testosterone may happen here [13].

TestoFuel is manufactured under FDA-approved conditions.


TestRX vs Nugenix PM-NMA

TestRX is yet another safe, natural testosterone supplement that claims to boost testosterone. It features some of the ingredients we’ve already discussed here including Zinc, Magnesium, Fenugreek, D Aspartic Acid, and B6. 

Unfortunately, we can’t know for certain if either TestRX or PM-NMA are FDA-approved.

PM-NMA contains all of those, as well, but with a high concentration of Magnesium at 450 mg. Because of this, it’s considered a “nighttime” T booster, as the Magnesium will help the body relax and sleep.

This makes the capsules unique compared to others, so if you blame poor sleep for low testosterone, this option might be suitable.

Do Testosterone Supplements Really Work?

There’s loads of evidence across the internet, in scientific and medical journals, that lead us to believe that some testosterone capsules work. This depends on a variety of factors:


  • What are the ingredients?
  • What’s the quality of those ingredients?
  • Does the manufacturer of a certain product abide by strict production standards?
  • Does the user follow the instructions?
  • Does the user support their supplementation through exercise and a healthy lifestyle?

Nugenix and Men: What Happens After You Take It

According to the company, once you start taking the testosterone booster capsules, you could experience the following benefits:

  • Increase testosterone
  • Boost in energy
  • Better vitality
  • Increase muscle mass
  • Higher libido
  • Stable cortisol levels
  • Better fitness
  • Better blood flow

But Nugenix is still far from the best testosterone booster on the market still.


How Long Until the Effects of Nugenix Kick In?


It could take anywhere from a few weeks to over a month for the effects of Nugenix to kick in and your testosterone level to rise.


As previously mentioned, this depends on a variety of factors from your lifestyle to the quality of ingredients in the supplement itself.


Generally speaking, you may notice small differences in your body on a day-to-day basis with the full range of benefits showing up later.

What Are the Side Effects of Taking Nugenix?


The side effects or health risks of taking the Nugenix Testosterone Booster supplement may be wide-ranging and dependent on the consumer.

There’s not a single dangerous ingredient in the Nugenix product, given most of them are all-natural. You’ll find no actual testosterone hormone, for example. However, just because the ingredients are natural, doesn’t mean they’ll affect you, or your testosterone, positively.

Of course, you don’t want to take any supplement or product that poses safety risks to the human body.

Here are a few of the side effects that might occur in your body with one of the testosterone booster supplement:


  • Upset stomach
  • Racing heart
  • Troubles sleeping
  • Swollen ankles or feet
  • Enlarged prostate
  • Blood clots in legs


We always recommend that you consult with a trusted doctor before taking a testosterone pill or product.

How Should I Take Nugenix?


This depends on the exact Nugenix testosterone product you’re interested in, whether it’s the PM-NMA or Total-T.

Nugenix Free, for example, requires that you take three capsules per day, on an empty stomach and with a glass of water. PM-NMA has a daily dosage of four per day and right before bed.


If you miss a dose, don’t worry. It’s better to go about your schedule as normal, versus trying to catch up. Depending on the ingredients, your body may not absorb the extra amount you take anyway, making it a waste.


Taking a double dose or more could also lead to unwanted side effects like stomach pain or jitteriness in men.


Faster Results?


There’s nothing to stop you from trying to achieve faster results with a testosterone product.

However, there’s also nothing to say it’ll work.


Instead, you can complement your new testosterone booster routine in more ways:


  • Get at least 8 hours of sleep per night
  • Eat a well-balanced diet
  • Keep stress levels low
  • Maintain a strict exercise routine

Where Is Nugenix Manufactured?

This testosterone product is manufactured in both the United States and Canada.

Nugenix Review in Conclusion

As you can see, a supplement can offer an array of natural ingredients that may support testosterone including Vitamin B12 and L arginine, for example. By nature, these substances aren’t dangerous and probably don’t come with safety concerns for most people.


However, based on what we’ve found, product to product, this company isn’t FDA-approved, so we can’t attest to the overall quality that goes into the manufacturing process. There are alternatives, such as TestoFuel, HunterTest and TestoGen that feature similar ingredient lists and come with better reviews.
