Testosterone is an important male hormone, affecting muscle growth, libido, bone density, and even playing a role in self-esteem and competitiveness, but levels decline naturally with age. Supplements containing natural ingredients that may help to increase testosterone levels are increasingly popular, but it can be difficult to know what will actually work, what is safe, and what may cause side effects. Nugenix is one testosterone boosting supplement that claims to boost libido, sexual performance, drive and strength.

Below we take an in-depth look at Nugenix to see if it can really boost libido and improve sexual performance.

Nugenix Pros

  • Available from reputable third party retailers

Nugenix Cons

  • Autoship Program when using official website
  • Expensive supplement
  • Some reviewers who had blood tests report no increase in testosterone levels
Watchdog Rejected Muscle Pills



What You Need To Know About Nugenix

Nugenix is a testosterone boosting supplement intended for men over the age of 50. The manufacturers state that it will improve libido, performance, confidence and drive. This is achieved by increasing free testosterone levels in the body.

What Are The Side Effects Of Nugenix?

Some of the ingredients in Nugenix can cause side effects, but overall they do not appear to be very common or severe. Nugenix could lower blood sugar levels and so should not be used by anyone with diabetes.

How Much Does Nugenix Cost?

With the daily serving of Nugenix being three capsules, a small bottle of 42 capsules will only last for 14 days, whilst the larger bottle of 90 capsules provides a 90 day serving. This makes the supplement quite expensive, especially when ordering from the official manufacturer’s website, as they sign customers up for an auto-ship program which charges them monthly.

Our Verdict On Nugenix

Overall, we do not recommend Nugenix to our readers. If, however, you are set upon trying this product, we recommend avoiding the Nugenix official website (and auto-ship program); instead, it is best to order from a third party retailer.

The manufacturer’s returns policy is complicated by the auto-ship program they sign customers up for, and consumers may not be able to get all of their money back depending upon their individual circumstances.

The main ingredient in the product, Testofen, has been the subject of several law suits as the claim that it boosts testosterone levels is debateable, depending upon which clinical trials are read. The other ingredients in Nugenix will not boost testosterone levels, but the supplement could boost endurance during exercise and could boost the consumer’s libido.

Overall, we do not recommend Nugenix to our readers.

Nugenix Review

Nugenix is a testosterone boosting supplement for men that promises numerous benefits, including an increased libido, sexual performance, drive and strength.

Nugenix Facts

  • Manufactured by Direct Digital LLC
  • 90 capsules per bottle

There is very little information about who manufactures Nugenix, but the label states that the product is distributed by Direct Digital LLC who are based in Charlotte, North Carolina. The official Nugenix website provided contact details, and lists the company address as being in Utah in the USA.

How to Take Nugenix

Take 3 capsules daily with water on an empty stomach.

Controversially, GNC were sued over the sale of Nugenix, with the lawsuit claiming that Testofen, the main ingredient found in Nugenix, does not boost testosterone levels at all. The lawsuit cited several studies, including one where the placebo group’s testosterone levels raised slightly, whilst the Testofen-taking group actually had slightly lower levels of testosterone by the end of the study. We were unable to find the results of this lawsuit (which could still be on-going), but as Nugenix is still being marketed as a Testosterone boosting supplement, we believe that the lawsuit was unsuccessful.

Nugenix Concerns:

  • Autoship program when ordering from official website
  • Testofen has been subject of several law suits over effectiveness
  • Complicated returns policy

What Does Nugenix Claim To Do?

According to the manufacturers,

Nugenix is an all natural Testosterone booster that contains clinically studied ingredients that are proven to boost free testosterone levels.

Nugenix helps to:

  • Increase Sex Drive
  • Enhance Muscle Mass
  • Boost Free Testosterone

Does Nugenix Work?

The clinical support available to suggest that Nugenix increases testosterone levels is limited. Only one of the ingredients, fenugreek extract, appears to have any affect upon testosterone, but only one of the four human studies actually showed this effect. The other three studies showed no changes in testosterone levels, or even a slight drop.

The other ingredients in Nugenix do appear to be more effective than fenugreek extract. Citrulline Malate supplementation appears to reduce fatigue and improve endurance in exercise, but does not appear to have a significant impact upon muscle mass compared to supplementing other amino acids.

Tribulusterrestris appears to act as a libido booster, but does not affect testosterone levels.

Overall, we believe that Nugenix will not boost testosterone levels significantly, but it does contain ingredients that could improve endurance and libido.

What Are The Ingredients of Nugenix?

The ingredients used in Nugenix are detailed below. The ingredient quantities provided are per serving of three capsules, which is the daily maximum dosage. Individual ingredient quantities are not listed, but a proprietary dosage is listed.

Zinc 5 mg (7% RDA)
Vitamin B62 mg (100% RDA)
Vitamin B1250 mcg (850% RDA)

Nugenix Testosterone Complex 2103 mg

  • Testofen(R) Fenugreek Extract 50% Fenuside (Tm): Whilst one study has shown that Fenugreek extract can increase testosterone levels, other studies have provided conflicting results, showing either no increase in testosterone levels or even a slight drop.
  • L-Citrulline Malate: Citrulline is an amino acid produced naturally by the body. It does not appear to affect testosterone levels at all, but may play a role in reducing blood pressure, improving blood flow, and reducing fatigue. The body converts L-Citrulline Malate into L-arginine in the kidneys.
  • TribulusTerrestris (Fruit): The root of this plant appears to enhance libido and ‘sexual well-being’ but does not affect testosterone levels.

Does Nugenix Have Any Side Effects?

Some of the ingredients used in Nugenix could potentially cause side effects.

Possible side effects of Fenugreek extract include diarrhea, stomach upset, bloating, gas, and a “maple syrup” odor in urine. Fenugreek can cause nasal congestion, coughing, wheezing, facial swelling, and severe allergic reactions in hypersensitive people. Fenugreek might also lower blood sugar, and so may not be suitable for diabetics.

TribulusTerrestris may also lower blood sugar levels. The long term safety of tribulusterrestris is unknown.

Not suitable for use by women. Not suitable for anyone under the age of 18. Recommended for use only by men over the age of 50. Consult your doctor before purchase if you have any serious medical condition, or if you are taking any medications. Not suitable for anyone who has high blood pressure. Not suitable for diabetics.

Are There Any Customer Reviews For Nugenix?

There are numerous customer reviews for Nugenix at the various different third party websites where it is sold, including amazon and GNC. Customer opinion varies hugely, with some noticing increased energy levels, whilst others noticed no benefits or developed side effects, including heart palpitations. We did find one review stating that it worked from day one; it may be that some people notice benefits due to a placebo effect, especially sexually.

My husband used this product and trust me ladies it works. Day two!! No need to say more! 🙂


This is a completely ineffective product. I will go so far as to say it is an outright fraud. It delivered none of the stated benefits. It has a horrible odor and taste and upsets my stomach. I have canceled my monthly delivery program. I would not recommend this product to anyone.

I’m 33, 5’11, 150lb, workout 3-4 times a week and eat clean.
I had my testosterone levels tested a few month ago and my levels were 399 (under 400 is considered low). I took 3 pills per day for about 3 months, got tested again this week and my levels are 298.
So this product has been ineffective for me and I’m just gonna stop taking it.

After taking the product for about 2 1/2 weeks my blood pressure increased from 130/75 to 145/85. I did feel (or thought I felt) an increased energy level but not worth the PB issue.

I normally take chryssin plus bioperine to increase the absorption rate, to increase my free testosterone. This works well, and I see the result with my toned muscles from my regular workouts. I decided to try this because of the process that they produce it through, and stop the chryssin regimen. My muscle tone went down, and I became a bit flabby after three weeks. Sucks. I went back to chryssin. Why mess with a good thing I guess.

I’ve been taking Nugenix for three months now and saw a difference into the second month. I was a little skeptical at first because of all the reviews but decided to allow myself to take it for three months to see if the product worked and to give it a fair shot (since every ‘body’ is different and works differently). Since taking the product I’ve noticed my stamina has increased ALOT. I can train longer and not tire out so easily. In regards to muscle mass, I’ve noticed a difference but also diet and training contribute to that as well. Increased sex drive I did not see an improvement since I have no problem in that category. Just for info….I’m 41 years old, 6′, 210lbs, athletic, eat clean and train 5/6 times a week besides my full time job where I work 12-14 hour days. The only downside to this product I have found is the nasty aftertaste if you burp after taking your dose. I have found drinking 24-32 ounces of water with my dose was enough to push it down and quickly absorb. I hope this is helpful to anyone considering Nugenix. I tried to be as honest as I could with this product. Good Luck

Most of the people giving it 1 star reviews are people that ordered directly from Nugenix. Their site offers a free trial, but auto signs you up for the next full bottle in 14 days. No one read the fine print, and are mad… Just order from amazon and you will be fine. The produce itself works good for me. I don’t take it for libido, but it does help that too. I noticed better muscle gains with it, and quicker recovery time. I don’t take the full dose of 3 pills, I only take 2 a day. I recommend it for a try, everyone’s bodies work differently, so you might see more or less effects than I did. I would adjust the dosing depending on how your body reacts to it.

I took advantage of the free trial, but I did not see any results. However, I had also paid for another month’s supply (unintentionally). After the full month the differences began in my energy levels and my stamina (especially at the gym). I did not really notice, but other guys my age asked how I was getting so much energy. My wife then began asking what had gotten into me (energy levels and ability). So, I bought two more months supply. So for me, this product was a slow starter, but I am now enjoying the results.

Your product has a negative side effects on me. I had palpitations and elevated heart beat. I immediately stop using the product. I would like to return the product and get a refund?

Does Nugenix Offer a Money-Back Guarantee?

The official Nugenix website has a complicated returns policy for all products ordered through their official website. Anyone who has signed up for the auto-ship program is offered a 30 day satisfaction guarantee, with the company accepting opened products for return as long as an RMA number is obtained first, and written clearly on the returns parcel. This policy appears to be in place to help out consumers who have forgotten about the auto-ship program and who have received unwanted deliveries of the supplement.

However, anyone who has made a ‘standard’ order that does not come with an autoship program, cannot return any bottles that have been opened or used.

The returns policies of third party retailers may vary, and should be checked individually.

Where Can I Buy Nugenix?

The supplement is available as a ‘free’ trial from the official Nugenix website, but the customer is signed up for an expensive autoship program that sends a new bottle out monthly. We disapprove of auto-ship programs as they are often difficult to cancel, and are often not clearly explained unless reading through the length terms and conditions.

When customers order the initial ‘free’ trial, they will be charged $4.99 for shipping and handling. If they do not cancel their trial almost immediately, then they will be charged $69.99 plus taxes and delivery charges per month until the auto-ship program is cancelled.

The website’s terms and conditions page states:

Beginning about 18 days after you place your order, you will be charged $69.99 plus $4.99 S&P and any applicable tax, and automatically receive an additional 30-day supply of Nugenix. You will continue to receive a fresh 30-day supply of Nugenix about every 30 days for as long as you stay a member of our auto-ship program. The card you provided when you ordered the trial product will be automatically charged $69.99 (plus $4.99 S&P and tax if applicable) when each new product ships. To cancel future shipments in the auto-ship program, you must call 1-855-714-3234 at least 1 day prior to the date that your next monthly delivery ships.

There are also several third party retailers that sell Nugenix. Vitamin Shoppe sell a bottle of Nugenix containing 90 capsules for $57.99, with free delivery.

The product is also sold at amazon. A bottle of 42 capsules costs $52.90 plus delivery charges. A bottle of 90 capsules costs $37.19 with free delivery, whilst 180 capsules (two bottles) costs $89.99 with free shipping. Obviously the 42 capsule and 180 capsule options are not very good value for money.

From GNC a bottle of 90 capsules costs $69.99 plus delivery. It is also available from selected GNC stores in the USA. Anyone who has a GNC membership can buy the product for $49.99.
