Before we fully delve into what Nugenix’s products really are, let’s first go over the basic principles for what testosterone boosters can do for us. In recent years, there has been a lot more hype over testosterone boosters, than there has ever been.

This is likely due to the average male taking a lot more interest in their physical appearance, as well as their sex drive. Testosterone boosters were originally mainly used for hardcore bodybuilders or those who suffered from libido problems.

These days, testosterone is supplemented by many people throughout the world, whether it’s for its muscle and strength building properties, or simply to help replace the testosterone that is lost with age.

Testosterone is a hormone that is primarily found in men, but women have it also. The testicles are what produce this hormone for men. Women’s ovaries also produce it but in smaller amounts.

Testosterone production increases significantly during the age of puberty, but it begins to drop at around the age of 30.

Some of the symptoms of low testosterone include:

– Low sex drive
– Increased weight gain
– Less energy
– Low self-esteem
– Feelings of depression
– Moodiness
– Thinner bone density
– Less body hair

However, the benefits of having an increased testosterone level include:

– Increased strength gains
– An elevated sex drive
– Decreased body fat
– Increased muscle mass you

Testosterone is most commonly associated with sex drive and is crucial for adequate sperm production. It also affects muscle mass and bone density, as well as the ability to store and get rid of fat.

Nugenix products

Nugenix is a testosterone supplement manufacturer from Boston, USA. They produce five different supplements that are all aimed at helping your body to produce testosterone and to balance hormone levels.

Their products are as follows:

  1. Nugenix Free Testosterone Booster – This supplement utilizes eight specific ingredients that have apparently been proven to help boost your natural testosterone levels.
  2. Nugenix Prostate Health Support – This prostate health support supplement contains ingredients that will contribute to the health of your prostate, which will reduce nighttime urination and help to promote urinary flow.
  3. Nugenix PM-ZMA – PM-ZMA has been designed to be used for testosterone production at nighttime.
  4. Nugenix Ultimate – Similar to the free testosterone booster, the ultimate version has been designed for those who are looking for massive amounts of testosterone support, whether that’s for their gym activities, or just for daily life.
  5. Nugenix Estro-Regulator – This supplement has been designed to be stacked with any of the testosterone booster supplements, in order to balance and regulate both testosterone and estrogen.

Nugenix testosterone boosters work by providing the body with a natural boost to increase your free testosterone levels, as well as to help to inhibit hormones that are responsible for turning testosterone into estrogen.

These supplements are primarily used by bodybuilders, although they are also common with men who are suffering from a low sex drive.

Most testosterone that is in your blood will attach itself to one of two proteins:

  1. Albumin
  2. Sex hormone binding globulin

However, some testosterone doesn’t get attached to any proteins and is considered “free”. This free testosterone, as well as the albumin-bound testosterone, are bioavailable and can be easily used by your body.

The pituitary gland is responsible for controlling the levels of testosterone in your body. When testosterone is low, this gland should release a hormone called luteinizing hormone which will tell the testicles to produce more testosterone.

All of the ingredients in Nugenix have been added to help produce more of this luteinizing hormone, which should results in your testicles producing more testosterone, at least while the supplement is still in your body.


The ingredients for these supplements are all naturally occurring, so from a safety perspective, in theory, this is a relatively safe product. All of the ingredients have a fair amount of scientific data supporting their use and purpose.

As always, if you are suffering from a medical condition, it is certainly advisable that you get advice from your local doctor. You should do this with any dietary supplement that you intend to take.

Although these side-effects are not unique to testosterone boosters, men who have taken these types of supplements reported the following side effects:

  • Oily and acne prone skin, just like you may have had when you were going through puberty.
  • Sleep apnoea, as well as difficulty in sleeping.
  • Testosterone doesn’t help to grow or support ligaments and tendons, therefore if you build too much muscle mass too quickly, you can injure yourself.
  • It’s possible for testosterone boosters to damage the kidneys if used over a long period of time.
  • Infrequent urination, although additional water consumption can combat this.
  • Some people can report an increase in aggressive behavior. If you are not prone to flashes of anger, then you should probably lower your intake of testosterone boosters.
  • Prolonged use of testosterone boosters can enlarge or inflame the prostate gland. This is likely why Nugenix have created a prostate support supplement, which they advise should be utilized alongside the testosterone boosters.

From taking natural testosterone boosters, it’s quite unlikely that you will experience any of these side-effects. However, if you do, it’s advisable that you stop taking them straight away, and consult your doctor.

Nugenix ingredientsVitamin B-6 (2mg)

Vitamin B-6 (as Pyridoxine Hydrochloride) boosts testosterone levels directly, and indirectly. It helps to promote the production of androgens. These androgens cause testosterone levels to rise, but can also help the brain to regulate the creation of hormones which affect testosterone levels in a bad way, like estrogen.

B-6 has also been found to help reduce the levels of prolactin, which is the hormone responsible for “man boobs”. Vitamin B-6 cannot be stored by the body, and needs to be ingested regularly. (1)

Vitamin B-12 (50mcg)

The B-12 (Methylcobalamin), just like B-6, needs to be consumed regularly as the body cannot store it. It’s responsible for a number of essential bodily functions, including the formation of red blood cells, DNA synthesis, fat metabolism, and protein metabolism.

Zinc Chelate (1mg)

Zinc is something that has numerous positive effects on the body, but it’s also known for its testosterone raising properties. Having not enough zinc in your diet stops the pituitary gland being able to release the hormones responsible for stimulating testosterone production.

It’s also been shown to reduce the conversion of testosterone into estrogen too.

L-Citrulline Malate (volume not disclosed)

This is an amino acid compound which helps the body to delay the onset of fatigue, specifically from an intense workout. This is more specifically for those who are taking testosterone boosters to increase their performance at the gym.

Fenugreek Seed Extract (volume not disclosed)

Fenugreek extract has had a lot of hype in recent years, although it’s tough to find any credible trials that prove its effectiveness for actually boosting testosterone. There are, however, credible evidence to show it has powerful fat burning properties.

Tribulus (volume not disclosed)

This is another plant extract which is said to help boost luteinizing hormone levels, which should make the testicles produce more testosterone. However, there is low evidence that this actually works, as all published trials have shown no increase in testosterone levels, as well as no increase in physical appearance. A lot of products that are solely Tribulus even say that it “may” boost libido.

Nugenix Ultimate ingredientsNugenix’s other testosterone booster doesn’t have very many shared elements. Oddly enough, the only shared ingredient is Fenugreek extract (700mg). This product has been designed more specifically for bodybuilders it seems, but should still work for anyone who just wants to increase their testosterone.

D-Aspartic Acid (3000mg)

DAA is naturally found in the testes and pituitary gland and is an essential amino acid. There has been quite a lot of studies on DAA that prove that by consuming it daily you can increase your free testosterone by up to 40%.

It seems that DAA works better for men who already have low testosterone, rather than giving the same boost to men who have high amounts of testosterone.

Boron Citrate (10mg)

Boron is a mineral that naturally occurs in a variety of foods like certain nuts, fruits, and vegetables. Studies have shown that by supplementing additional boron, participants were able to see a significant rise in testosterone levels. It also helps to regulate estrogen,  as high levels of estrogen will lower testosterone levels.

Epimedium grandiflorum (650mg)

Horny goat weed is a flowering herb that grows all over Asia. As the name suggests, this herb has been used for hundreds of years due to its libido and testosterone boosting properties.

Mucuna Pruriens Extract (250mg)

Also known as the Velvet Bean, this plant naturally occurs in India and is used primarily for Parkinson’s disease and fertility issues. While studies showed that consuming Velvet Bean extract increased testosterone for infertile men, there seems to be little evidence of it having the same impact for those who have normal testosterone levels.

Maca Root (250mg)

Maca is indigenous to Peru and has been used for thousands of years as an aphrodisiac. However, there seem to be no credible studies that show that it actually boosts testosterone, or any of the other hormones that are responsible for increased testosterone production.

Stinging Nettle Extract (360mg)

Consuming stinging nettles blocks aromatase, which theoretically stops the conversion of testosterone into estrogen. However, there are no proven studies to show that it can actually boost testosterone levels in humans.

Tongkat Ali (200mg)

Tongkat Ali is found in Malaysia and Thailand and is used primarily due to its aphrodisiac properties. There are numerous studies to show that extract of this plant is able to enhance testosterone levels and sexual performance in men.

Nugenix official website

This is a screenshot of official manufacturer´s website taken on 19th of April, 2017. It may have changed since publishing this article.

If you’d like to buy any of Nugenix’s products, doing so through the manufacturer’s website should be the simplest way to do so. However, for whatever reason, they also advertise some of the other retail establishments which sell their products too, with a link to their site.

On closer inspection, there seems to be some variance in the product quantities and prices. A quick example would be that on the manufacturer’s website the Free Testosterone Booster is $69.99 for 90 capsules (30-day supply), whereas the Amazon listing is $31.00 for 42 capsules (14-day supply) / $52.97 for 90 capsules / $93.95 for 180 capsules.

The Nugenix’s website also does not seem to have any deals or multibuy saving options available.


When trying to purchase Nugenix through its official website, there are six options to choose from. The prices for bottles of each product (each bottle offers 30 servings) are as follows:

  • Nugenix Free testosterone booster for $69.99
  • Nugenix Ultimate for $89.99
  • Nugenix Estro-Regulator for $49.99
  • Nugenix PM-ZMA for $39.99
  • Nugenix Prostate Health Support for $34.99
  • Nugenix Multivitamin for $49.99

Shipping costs $4.99 and is only available to residents of USA and Canada. If you’d like to purchase any of these products from any other country, you’ll have to do so through a third-party retail outlet.

“Don’t waste your money! There are regular vitamins that tested better than this.
Obviously, everyone’s body is different.”


“Only been using Nugenix 1 month seems to boost energy level with my daily workout routine everything else works well.”


“Disappointed after a month. No change in any area. It may take a couple of months but I am not willing to spend the money to find out.”

As with all products in this category, there seem to be mixed results with consumers. The product claims to be able to help restore testosterone levels as well as to provide increased energy.

User testimonials seem to reflect approximately a 50% satisfaction rate, with some making claims that it did nothing for them whatsoever, whereas others seem to swear by the product. As testimonials like this can never be verified it’s impossible to know how long each person actually took the product for, as well as any other external influences, like diet and sleep.

However, at the time of writing, this product is ranked at the number one position for testosterone boosters on


It is not unusual that many unethical companies producing male enhancement pills pay for fake user testimonials to promote their products. That is why you need to be critical when assessing user testimonials.

Luckily, fake ones have usually at least few things in common:

  • These are extremely positive promising huge (often unrealistic) gains
  • These often state that their results were achieved very quickly
  • If going through user reviews on Amazon, ignore those that are not marked as “Verified Purchase”

Just keep in mind that you always need to take extremely positive claims with a grain of salt (even if these are genuine). It is better to be safe than sorry.

30 day guarantee

When purchasing through the manufacturer’s website, they offer a free trial, where if you cancel before 14-18 days have passed, you will not be billed, and you will not be shipped any more bottles.

This is a quote from their FAQ section on free trials:

“Our free trial offer does not obligate you to purchase our product. If you cancel before 18 days have passed, you will not be shipped more Nugenix nor billed any additional charges. You can keep your free bottle as our gift to you.”

However, if you forget to cancel, you are signed up to their auto-shipment program. But do not worry, it can be easily canceled too.

“After your free trial, if you wish to receive a refund for your purchase, you need only send back the unused portion within 30 days of the date the product was shipped to you and a full refund will be provided. Refunds will be provided regardless of the reason for dissatisfaction.”

“In order to receive a full refund, you must contact our customer service department at *-***-***-****. Our customer service team will give you a Return Merchandise Authorization number and return shipping instructions.”

[I have intentionally left out that phone number as it may change since publishing this review. If you need it just check out their official website]

They also provide a 30-day money back guarantee on the autoship bottles which they state that they will completely refund any returned product, including any shipping and processing fees.

Here is a quote from their FAQ section:

“… we provide a 30-day money back guarantee. This means that we offer a complete refund (including shipping and processing) for any returned product postmarked within 30 days of the date the product was shipped to you.”

However, if you purchased your product on their official website and not through the auto-ship system, then you still have the 30-day money back guarantee but conditions are different. You can return only bottles that are unopened.

They also go on to say that all individual testimonials that are featured on their site are real people who have consumed the product. They then continue to say how each person has signed legal consent forms to allow them to publicize their testimonial.

For best results, they recommend that you should use Nugenix for at least eight weeks alongside a strength training program. This could be why so many people had bad results, as they didn’t incorporate any exercise into their life.

From looking at the specific ingredients, the Nugenix Free Testosterone Booster has all the right compounds to help support testosterone production. However, the ultimate version seems to have too many unproven ingredients or ingredients that have just been shown to help increase libido, rather than actual evidence of testosterone production.

Amazon bestseller:

It’s also worth reiterating that the Free Testosterone Booster is the most sold testosterone booster on the store.

Various user testimonials:

While user testimonials seem to be about 50-50 on whether it’s a good product or not, it could be that the majority of people who are happy with the product are just not interested in leaving a review.

Free trial offer:

With their free trial offer, or even utilizing Amazon’s 30-day return policy, you will be able to test out this product yourself to see whether it benefits you in any way, without losing money.
