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.

What is Andro400?

Andro400 is a natural dietary supplement that, when taken once a day, is supposed to increase testosterone. More testosterone leads to an increase in muscle mass and a corresponding decrease in belly fat. As a result, taking Andro400 improve your overall health.

The product’s website recommends Andro400 for men or women in their 20’s or 30’s who are seeking an energy boost to complete higher levels of physical activity. For those who are a little older, Andro400 claims to increase the production of testosterone. Other benefits listed are lower cholesterol, an increase in the body’s basal metabolic rate, and improved energy levels and libido.

Andro400 is not a drug and contains no synthetic materials. It is an herb that does not supply testosterone but is supposed to free or unbind the testosterone that is already in your system. The result is that you can enjoy the total benefits that testosterone provides.

Bottom Line – The makers of Andro400 make some big claims about the formula, including support for testosterone production.

Andro400’s Secret Ingredient?

It is easy to discuss the Andro400 ingredients since there is only one. The major component is Eurycoma Longifolia, and ancient civilizations believed it was a secret and powerful compound. Eurycoma Longifolia is a plant indigenous to the countries of southeast Asia.

This plant was widely used because the natives believed that it had a variety of medicinal effects. They would boil the root of the plant in water and then drink the liquid. In this way, they would treat malaria, diabetes, digestive issues, fevers, and headaches.
Eurycoma Longifolia, also known as Tongkat Ali, is now used to increase testosterone

  • It is an antioxidant.
  • It is an anti-inflammatory and often used to reduce swelling and pain.
  • It can also be used to improve circulation and as an aphrodisiac

Bottom Line – Eurycoma Longifolia, which is the only ingredient in Andro400, has been used for a variety of medicinal benefits across the world.

Andro400 Customer Testimonials

Does Andro400 (Eurycoma Longifolia) Work?

Clearly the Eurycoma Longifolia plant has some health benefits. But are the Andro400 weight loss, muscle building, and better performance claims true? Is there an Andro400 scam?

The company making Andro400 markets the product by stating that Eurycoma Longifolia stimulates the body’s pituitary gland to produce testosterone naturally. Increased testosterone leads to an increase in muscle mass. Muscles use more of the body’s energy and therefore increase metabolism and fat burning. That means Andro400 could, in theory, affect weight, according to a study in the Journal of the International Society of Sports Nutrition. [1]

The same study does go on to say, “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.” [2]

So that’s how it is supposed to work, but are there tangible results? The company’s aggressive marketing campaign dramatically increased sales but also led to an increase in research as consumers looked for information to validate claims.

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. [3]

Does Andro400 Eurycoma Longifolia Work
Much more of the research was conducted on animals. Research published in Evidence-Based Complementary and Alternative Medicine, as shared by the National Institute of Health, found some increased testosterone levels in rats that were injected with Eurycoma Longifolia. There were some positive results in human studies, but it was also found that the herb is not well absorbed by humans when taken orally, in pill form. [4]

Through the years, Eurycoma Longifolia has been effective in treating a variety of issues. But those results were achieved by taking the herb in liquid form. It seems that the best that can be said about Andro400 is that it contributes to an increase in testosterone levels.

Presently, there is not enough evidence to support the more widespread claims. However, since the liquid seems to be more effective, Eurycoma Longifolia has been added to liquid supplements and energy drinks.

Bottom Line – The liquid form of Eurycoma Longifolia has been successfully used to treat a number of diseases and conditions. Today’s research shows that Andro400 does have some impact on boosting testosterone.

Andro400 Side Effects

I searched multiple websites to find Andro400 reviews and Andro400 complaints, and to answer the question “is Andro400 safe?”

I could find no reported negative Andro400 side effects. This makes sense since the only ingredient is an all-natural herb that has been used for hundreds of years. However, there are some dangers to excessive testosterone production: [5]

  • Excess testosterone is converted by the body to estrogen.
  • An increase in estrogen leads to fat production.
  • Excess Andro400 testosterone can lead to male pattern baldness.

Bottom Line – Is Andro400 safe? According to our research, Andro400 is not likely to cause harmful side effects because its ingredient is all natural. We read that you can take this product for up to nine months.

Cost of Andro400 and Where to Buy

Though popular, Andro400 can only be purchased from two online sites. Searching for Andro at Walmart, Amazon, and GNC produces multiple alternatives but not the named product so be careful when you do your research.

On the official website, Andro400 costs $39.95 for a one-month supply. If you order the product in bulk, the per bottle cost is less. The cheapest way is to have it auto-shipped each month at the cost of only $29.95.

On eBay, one month’s supply ranges from $27.99 – $38.99 depending on the supplier.

Andro400 comes with a money-back, 90-day manufacturer guarantee. If you do not see results in that time, you can return your product for a full refund. The return policy detailed on the website, explains that you can return the empty bottle, partially empty bottle, or unopened bottle, and your refund will be issued within two business days.

Cost of Andro400 and Where to Buy

When you search for Andro400, don’t be confused by the Andro400 MAX. Andro400 MAX is an alternative product that contains Eurycoma Longifolia plus the amino acids L-Arginine and L-Citrulline. This combination is more suited as a testosterone replenisher and is recommended by the company for men over the age of 40.

To provide a complete review, we also searched for Andro 500 and Andro 4000. All my attempts directed me back to Andro400 and there is no mention of either of those products on the company website. If Andro 4000 or 500 existed at some point, it seems they are no longer in production.

Bottom Line – Andro400 is reasonably priced but your options for purchase are somewhat limited. Though the product is guaranteed, there have been complaints that it is difficult to receive a refund. The other issue is that the automatic shipping program is almost impossible to cancel.

Andro400 Company and BBB

The contact information for the Andro400 company is:

Natural Health Concepts
5407 N. Haverhill Rd #336
West Palm Beach, FL 33407

One caution is that, though the above Natural Health Concepts is the parent company listed on the Andro400 website, Natural Health Solutions is the alternate name given for the company on the Better Business Bureau (BBB) website. Adding to the concern is that there is no information or web presence for either of these company names.

Andro400 has had an open BBB file with a California address for the past twelve years. It is listed as an herb production and distribution company with a customer service management system. There are no Andro400 reviews posted on the BBB site, and since the BBB rating is based on reviews, the company currently has an overall rating of A+. [6]

Andro400 Customer Service

The website provides a few alternatives for customer service and encourages customers to contact the company to discuss any issues.

  • By Phone – Call Customer Care at 877-711-3173
  • Mon – Fri – 8:30 am – 11:00 pm Eastern time
  • Sat & Sun – 9:00 am – 5:00 pm Eastern time
  • By email – Support@Andro400.com

Andro400 Customer Service

Bottom Line – The company website details the contact information and seems to make accessing customer service an easy process. Since the only complaints, we could find centered around refunds, we called the customer service number to speak with a representative. The person we spoke with assured us that the company always honors the stated guarantee. He was very pleasant, but then again, we weren’t asking him for money. There are no BBB complaints or cases filed. However, it seems difficult to trust a company that provides no information on either of its aliases.

Andro400 vs. The Competition

The comparisons between Andro400 and some of the best-selling testosterone enhancers center around ingredients and dosages. The major difference is that Andro400 is the only product in the group that contains a single ingredient. The obvious similarity is that all products have some success in increasing testosterone or fighting the symptoms of low testosterone.

Andro400 vs. Nugenix

Andro400 has one ingredient which is taken in a 300-mg dose daily. Nugenix has eight components, and it is the combination of these, at higher dosage levels, that leads to more effective results.

Andro400 vs. Ageless Male

The Andro400 vs. Ageless Male contest is a case of four ingredients vs. one. In this case, the one wins. Both Ageless Male and Andro400 ingredients are of high quality, and both products show some proof of boosting testosterone. However, the levels of ingredients in Ageless Male are too low to match the level of Eurycoma Longifolia in Andro400.

Andro400 vs. The Competition
Andro400 vs. Nugenix UT

In Andro400 vs. Nugenix UT, the results favor UT. Not only does it claim to increase testosterone, but it’s also supposed to regulate hormonal levels for optimum performance. The UT formula is one that includes DAA and Mucuna Puriens, two of the more researched ingredients on the market today.

Andro400 vs. Prime Male

By all reports, Andro400 vs Prime Male is the closest contest. Both work in a similar way by stimulating the body’s own testosterone production. One difference is that Prime Male has 12 ingredients, but the overall dosage and effect is likely to be similar.

Andro400 vs. Testogen

Depending on the brand of Testogen you purchase, it can contain up to four ingredients. However, the doses of both products are similar, but Andro’s Eurycoma Longifolia ay just be more effective.

The Bottom Line – The Andro400 Results

History has shown that Eurycoma Longifolia, the only ingredient in Andro400, has a variety of health benefits. More recent research has shown some evidence that the product does have some positive impact on boosting testosterone. However, it is less clear that, when taken orally, it has a more widespread effect on general health and performance.

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 Boost. It’s a blend of nine ingredients. All clinically-tested with results showing help improving testosterone levels, strength, energy and more.

Also, they’re convinced you’ll love the supplement, so they’re offering a 120-day money-back guarantee and 2-Week Sample.

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.)

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.

Andro400 Ingredients

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.

      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.

      • mark

        It’s also a toxic exipient and if you take significant other supplements (which most have magnesium stearate), this could be a problem long-term.

  • 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

    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
