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?
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. 
“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 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 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.  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.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 because of the ineffective amount of eurycoma longifolia. We’re also concerned that there is no website or BBB file for Natural Health Concepts.
