We hear a lot of buzz about Andro400, so we dove deep into the ingredients, side effects, and clinical research. We covered hundreds of user comments and reviews. Then, we collected all the facts, condensed and summarized to give you the info you need.
What is Andro400?
Firstly, Andro400 is a testosterone booster that contains Eurycoma longifolia extract.  When you take the supplement as two capsules once daily it claims to “melt belly fat,” increase energy  and spark sex drive. The container is relatively small, so there’s no trouble taking it with you, a benefit.
The product, which appears to be produced by Natural Health Concepts, offers no information on when it was introduced to the market. We also noticed many unfavorable customer comments on their Facebook page. The formula contains one natural ingredient,  a good sign. Purchases have to be made through the official website. We like that there are some positive comments but read on…
Effective Quantities – “Too Little?”
The first worry we have is about Andro400 ingredients. Based on studies completed by the International Journal of Preventive Medicine and Phytotherapy Research, it takes 400 mg of Eurycoma longifolia extract to achieve proven results.  “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 Andro 400 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 Andro400 review said, “Good product. 2 months in I can see results with exercise.”
Andro400 Weight-Loss Claims – “Supported?”
Some men and women searching for natural testosterone boosters  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. 
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.” 
We can’t go on without taking a look at the other side of the matter.
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 in a supplement, like not adding enough of the active ingredient, to slim your chances of long-term success. If Andro400 does not include the amount of Eurycoma longifolia it needs, you could be wasting your time.
The Science – “Clinically 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.  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. At DietSpotlight, science is a critical part of the review process. If a company cannot support claims, there’s a problem.Also: read our Pronabolin Testosterone Booster Kit review »
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 suggesting a supplement that uses an ineffective amount of the active ingredient. 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.
Also, they’re convinced you’ll love the supplement, so they’re offering a 120-day money-back guarantee and multiple-bottle discounts.
Previous Andro400 Review (Updated September 28, 2014):
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 FeaturesAndro400 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.

Disadvantages of Andro400
- There are a lot of customer complaints found online for this supplement.

Andro400 ConclusionIf 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.
Andro400 is a natural testosterone booster that's supposed to contain the "most highly researched and time-tested ingredients." Scientific references listed by Natural Health Concepts, the company behind the product, do not support this claim. There is a second formula in the line - Andro400 Max.
Andro400 Ingredients and Supplement Facts
Serving Per Container: 30
|Amount per Serving||% DV|
|Eurycomia Longifolia Radix Root Extract 100:1||150mg||*|
Other Ingredients: None
We decided to look closely at all Andro400 ingredients to give you the facts.
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.
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.” 
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.” 
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. 
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. 
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. 
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.
