We’ve heard a lot of buzz surrounding Andro400, so we dove right into the ingredients, side effects, and clinical research of this testosterone booster. We were thrown back by the outpouring of negative customer reviews from users who weren’t seeing results. Upon investigating the reason, we came across an issue with the ingredients, and more specifically, the studies behind them. There’s a long list of studies on the main ingredient – but nothing on the formula. Does it actually “melt belly fat?” Here’s the truth about Andro400.

Andro400 Readers: Click here to find out why we're giving away samples of our product, Pronabolin.

What is Andro400?

Firstly, Andro400 is a testosterone booster that contains:

  • Eurycoma longifolia extract.

Two capsules once daily is supposed to burn belly fat, increase energy and spark sex drive. There is research supporting this, to an extent, but most of it was carried out on rats. On the website, the makers say this supplement is designed for men in their 20’s and 30’s and says nothing about rodents.

The product, which appears to be produced by Natural Health Concepts, offers no information on when it was introduced to the market. Purchases have to be made through the official website, which is another bad sign.

Products Similar to Andro400

Andro400 Ingredients – “Too Little Too Late?”

The first worry we have is about Andro400 ingredients. Based on studies published in the International Journal of Preventive Medicine and Phytotherapy Research, it takes 400mg of Eurycoma longifolia extract to achieve proven results. [4]

“When it comes to backing a product with clinical support, you need have the right formula,” says our Research Editor. “There’s just not the amount needed in this to give users the benefits they desire.”

“I tried Andro400 for three months and got no benefit. Don’t waste your money,” offers one user.

Another customer reports, “Andro 400 did not work for me…after taking this for 4 months.”

We also found a few comments that showed some support.

As another Andro 400 review said, “Good product. 2 months in I can see results with exercise.”

Andro400 Customer Testimonials

Andro400 Weight-Loss Claims – “Supported?”

Some men and women searching for natural testosterone boosters [5] are looking to speed up weight-loss. Andro400 claims to offer this benefit. We found a single study that did show increased energy and the users lost more weight than the placebo group. We also found it can reduce stress related to dieting. [6]

The study published in Journal of the International Society of Sports Nutrition says, “All of the human supplementation trials, have been conducted on specific hot-water-extracts of Eurycoma longifolia (which is the traditional Malaysian preparation) produced using a patented extraction process to isolate and concentrate the bioactive compounds.” [7]

We can’t go on without taking a look at the other side of the story.

Some users have noticed changes. As one buyer said, “I have been using Andro 400 for about two months now. I lost a little weight.”

A customer also offered, “I have been taking Andro400 and I have seen a small decrease in weight and some extra energy.”

All it takes is one hiccup, like not adding enough of the active ingredient, to slim your chances of success. If Andro400 does not include the amount of Eurycoma longifolia it needs, you could be wasting your time.

Eurycoma Longifolia Benefits – “Proven?”

There is an extensive list of clinical studies that are supposed to support Andro400 ingredients. Most have nothing to do with the product, but we did find one that interested us.

The researched showed increased sexual performance when participants took 300 mg of Eurycoma longifolia daily. [8] Unfortunately for Andro400, all of the men were between 40 and 65 years of age. The supplement, according to the official website, is made for guys in their 20s and 30s.

The Bottom Line – Does Andro400 Work?

So what’s the final take based on Andro400 reviews and research? We like that the company offers a friendly customer service team that’s easy to reach, but we have reservations because of the ineffective amount of eurycoma longifolia. We’re also concerned that there is no website or BBB file for Natural Health Concepts.

If you’re ready to naturally boost testosterone levels, we suggest a supplement packing clinically proven ingredients in sufficient quantities that can increase energy levels to help you lose weight.

Among the best products we’ve found this year is the supplement Pronabolin. It’s a blend of nine ingredients. All clinically-tested with results showing help improving testosterone levels, strength, energy and more.

Does Andro400 work?

Research into eurycoma longifolia does show some connection with increased testosterone levels , but it is best combined with other ingredients that are also proven. (More is always better.) One issue with Andro400 is that the formula is geared toward men in their 20s and 30s, but studies show better results with men in their 40s and 50s.

You are supposed to take two capsules per day.

Natural Health Solutions, the company that makes Andro400, is not accredited by the Better Business Bureau (BBB). It has not been rated at this time.

Andro400 contains 150 mg of the active ingredient per capsule. Andro400 Max, on the other hand, supplies 250 mg.

Is Andro400 a testosterone supplement?

No, Andro400 is not a testosterone supplement. The natural ingredient is supposed to support or boost test levels, according to the product description.

How much does Andro400 cost?

Andro400 costs $34.95 per bottle. You take two capsules each day and a bottle contains 60, so it will last one month.

We decided to look closely at all Andro400 ingredients to give you the facts.

Eurycoma Longifolia

In Southeast Asia, there is a tall evergreen known as eurycoma longifolia. According to Malaysians, if a tea is made from it there is a noticeable change in virility and sex drive. No fruit or leaves are used, only the bark and root. Other conditions thought to be affected by the ingredient, according to naturalists, include cough, headache, diarrhea and high blood pressure.

What is it Supposed to Do?

Eurycoma longifolia contains chemicals that may have a positive effect on testosterone levels. An increase in test could result in a boost to sex drive and virility. It could also help fight the other symptoms of low T, which may include muscle loss, weight gain and low energy.

Clinical Research

Eurycoma longifolia scientific support abounds. Like many ingredients, you will find a long list of animal studies, but unlike others, there is also quite a bit of human clinical research.

According to the Journal of the International Society of Sports Nutrition, “daily supplementation with tongkat ali root extract [eurycoma longifolia] improves stress hormone profile and certain mood state parameters, suggesting that this “ancient” remedy may be an effective approach to shielding the body from the detrimental effects of “modern” chronic stress, which may include general day-to-day stress, as well as the stress of dieting, sleep deprivation, and exercise training.” [1]

When tested as a remedy for the common bond disorder osteoporosis, men showed positive signs. Research in Evidence-Based Complementary and Alternative Medicine says, “The main mechanism is via its testosterone enhancing effects for the prevention and treatment of androgen-deficient osteoporosis.” [2]

Yet another study in the journal Andrologia offers, “Eurycoma longifolia (Tongkat Ali; TA) is natural alternative to TRT [testosterone replacement therapy] and has been shown to restore serum testosterone levels, thus significantly improving sexual health. This includes significant positive effects on bone health and physical condition of patients.”

We also found it important to note that eurycoma longifolia can also have an effect on musculature in both men and women. The journal Phytotherapy Research says, “Treatment resulted in significant increases in total and free testosterone concentrations and muscular force in men and women…the study affirms the ergogenic benefit of TA [tongkat ali] through enhanced muscle strength.”

Is There Really Anything That Works?

If you’re looking to maximize the benefits of a testosterone booster, you want more than just one clinically tested ingredient. We stumbled upon Pronabolin a short while ago. It contains eurycoma longifolia with eight other ingredients that may have a positive effect on the symptoms of low T.

It’s important to note that the makers of Pronabolin are confident enough in the formula to offer a multi-bottle discount and a 120-day money-back guarantee.

Andro400 Scientific Abstracts

Eurycoma Longifolia Extract

63 human test subjects were used in a study testing the effects of Eurycoma longifolia on mood states and hormone profiles, specifically vigor, confusion, anxiety, depression, anger, fatigue, testosterone, and cortisol. Participants were given either 200 milligrams of the herbal extract or a placebo pill for a total of four weeks. Although no changes in depression, fatigue, or vigor were observed in either group, improvements in confusion, tension, and anger were noted in the experimental group. Additionally, researchers found there to be lower cortisol and higher testosterone levels in individuals supplemented Eurycoma longifolia. These findings suggest the herb might be an effective solution for negative symptoms caused by chronic stress. [1]

An undisclosed number of rats were used to test the effects of Eurycoma longifolia in comparison to testosterone, which was used as a control for the duration of the experiment. The animals were administered supplements containing 200, 400, or 800 milligrams of the herb per kilogram of body weight. 15 milligrams of testosterone per kg of body weight was administered as a control for a total of 32 days. Rats in the experimental groups were administered their respective supplement twice a day. Researchers found that rats supplemented with Eurycoma longifolia had lower sexual performance concerning ejaculation, intromission, and mounting than the testosterone group. Additionally, the test group experienced a higher growth rate of the prostate and seminal vesicles. Despite these findings, researchers determined other aspects of sexual performance were improved, allowing it to be a potential herbal remedy for problems associated with sexual performance. [2]

13 male athletes were recruited for a research study testing the effects of Eurycoma longifolia on testosterone and muscle strength. The test subjects were put into two groups and given either 400 milligrams of the herbal extract or a placebo for six weeks. After discontinuing use for three weeks, individuals were administered the extract if they were given the placebo in the first six weeks and vice versa. This second experimental period lasted for a total of six weeks. Urine samples were taken from all test participants. Researchers found no changes in urinary testosterone, liver, or renal functions, which suggests it is not an effective testosterone booster. However, Eurycoma longifolia would be safe for consumption per regulations written by the International Olympic Committee. [3]

36 male rats were administered either 15 milligrams of a Eurycoma longifolia extract per kilogram of weight or eight milligrams of a diluted testosterone supplement per kilogram of body weight. Both were given once a day for a total of six weeks. Animals who were supplemented with the extract did not experience the heightened testosterone serum levels, or bone volume increases the testosterone group did. These findings suggest that the herb does not have beneficial effects concerning testosterone boosting. [4]

What are the Details With Andro400?

It is no big secret that your body changes as you get older. This is completely natural and it is to be expected. Unfortunately some of these changes are not so great. For instance, men have reduced testosterone levels as they age. This can lead to low energy levels, a decreased libido, and even weight gain. Well, there are supplements available that are claimed to increase testosterone levels, which may improve overall health, while aiding with weight management. The product is Andro400. You can find this supplement on the official website for $29.95 per bottle. That's not nearly as price as products with similar formulations like Androzene. It is specifically for men, and it is sold with a 90-day satisfaction guarantee. Another similar product that is a muscle builder is Ripped Muscle X. It contains Creatine Magna Power supplying 120 mg of magnesium.


  • Eurycoma Longifolia 150mg

Product Features

Andro400 is taken daily, two capsules, and is stated to be safe and natural. This supplement is intended to increase libido, reduce body fat, improve muscle tone, elevate mood, boost energy levels, increase strength, control blood glucose levels, improve vitality, assist the immune system, increase bone density, improve circulation, lower bad cholesterol levels, prevent testosterone from being converted to estrogen, improve concentration, aid with anti-aging, and improve memory. There seems to be a commonality with Andro400 and products like Elite Test 360 in that they are both testosterone boosters. There is only one ingredient mentioned for Andro400's official site, and it is Eurycoma Longifolia. This is a natural herb that is found in the rain forests of Malaysia and Indonesia. Apparently it has been used for hundreds of years, and can be used by women as well. It helps the body produce more testosterone. Since testosterone is a natural hormone, you may want to consult a doctor before trying a supplement such as Andro400. This way you can make certain it is actually safe to take daily.

Advantages of Andro400

  • There is an FAQ section provided on the official website.
  • A 90-day satisfaction guarantee is provided with this product.
  • The supplement may help with muscle growth.

Disadvantages of Andro400

  • There are a lot of customer complaints found online for this supplement.
  • This supplement may lead to some side effects. (See Andro400 Side Effects).
  • Andro400 capsules lack proven fat loss ingredients like Green Tea.
  • There are safer supplements available to aid with weight management.
  • This supplement is not suitable for women.

Andro400 Conclusion

If you are struggling to lose excess weight, we strongly recommend a healthy diet plan, similar to Military Diet, and regular exercise. Though not quite like the diet claims of ED Miracle though. If you need a supplement to assist with weight loss in particular, we do not feel that Andro400 is the best option even though it has a decent BBB rating. After all, this product is more for increasing testosterone levels. This can be a tricky process, and you should really speak with a licensed physician if you need to improve your testosterone levels. There are many customer complaints and negative reviews posted online for Andro400, which is not reassuring.

    • Candace (Editor)

      Rodney, some users report facial flushing or redness, mild nausea or insomnia.

  • Affects testosterone?
    Robert Wagner

    My doctor told me taking your product can inhibit my production of testosterone is this true?

    • Devon (Editor)

      Hi, Robert. We are not affiliated with Andro400. Are looking to build muscle or increase testosterone? All the same, you should take your doctor’s advice above all. You might want to consider using a different supplement as well, like Pronabolin.

  • Ingredients qstn
    John R

    Question: does it contain magnesium stearate or any of those other toxic garbage additives?

    • Rich (Editor)

      Well John, the only ingredient listed on their website is Eurycoma Longifolia, which they claim is a natural herb.

    • RPh

      Magnesium stearate is a sometimes necessary ingredient to allow the compaction of drug into a solid tablet/pill form. It acts as a lubricant, of sorts, in powdered formulations that without which some tablets may not be possible.

  • Age requirements?

    Is Andr0400 safe for older men? to what age?

    • Rich (Editor)

      Robert, Andro 400 is targeted especially towards older men, likely between 34 – 65

    pacca (Verified User)

    After taking 400 I now can sing the 60s song “get on up” with a big smile on my face just like “BoB” in those tv commercials

  • NO RESULTS what-so-ever.
    Mark in Michingan (Verified User)

    One month behind me so far at the recommended 2 capsules a day of Andro400 Max. I’m a 63 y/o active man with a belly I’d like to get rid of. So far, no results what-so-ever. Decided to double my dosage for the next month. If that doesn’t work, I’ll be back here to report on their 100% satisfaction guarantee or your money back.

    • Montana (Editor)

      Hello Mark. We’re sorry you had such a bad experience, but we are not affiliated with Andro400. You may want to try a product with 100% natural ingredients, like Pronabolin.

  • Exercise & eat healthy!

    there isn’t any pills out there that can help you loose weight. Best bet is regular exercise and eat healthy. Or you can do liposuction

  • Sex drive, power + energy!
    Jim Y. (Verified User)

    I have been taking Adro400 Max for almost one month. At first I didn’t noticed anything, but have discovered increased sex drive. Somehow I feel empowered and more energized during the day. I haven’t noticed any side effects. I will try another month at least. I don’t understand how it will make me lose weight, but any additional boost might help. I am 64.

  • Did not work for me.
    Don Hendrix (Verified User)

    The amdro 400 did not work for me. After taking this for 4 months, went to a doctor and had my T level checked. It was very low. The doctor put me on a prescription testosterone, andro gel, and it got my levels up. I did feel better, have more energy, things better in bed, but I did not not lose any belly fat like in the ads for amdro 400. You will only put on muscle and lose weight if you exercise while on real testosterone. I now take the testosterone by injections, insurance quit covering the cost of the gel.

    • Karen (Editor)

      Hi, Don. It looks like you found the right solution for you. So glad you’re feeling better.

  •  ZERO benefits!
    Michael (Verified User)

    For the first month, I took 2 pills as directed (Andro400 Max)- ZERO benefits. Being 58 years old, I increased dosage to 4 pills in the morning as directed – ZERO benefits. I only need to lose 35lbs. to be at my perfect weight. During this time, I worked out 3 times a week for 1.5 hrs per workout. I have actually gained a few lbs. probably due to muscle gain. Bottomline, Zero increase in energy, sex drive, testosterone, etc… Additionally, I am not a drinker, nor smoker. I rarely eat fast foods and do not over indulge in snacks or garage foods. I rated this product a 1 star because there is NO zero star rating. I am now looking for a refund as advertised, seeing that I am under the 90 day limit and product is finished!

    • Your Name Peter L.

      Tell us your thoughts about Andro400. I believed the hype and the radio commercials. I’ve been taking the “ambo 400 max” formula for about 2 months. Started off as directed 2 pills a day for a week and now on 4 pills a day. I work out and increased my exercising but to no avail….Nothing. Feel the same as 2-3 months ago I e-mailed the company but they never replied
