Boost Your Test Levels Naturally With Nutrex Vitrix

Vitrix is a natural testosterone enhancing supplement that's made by Nutrex - a supplement maker with several popular products including Vitargo CGL creatine and Lipo 6 fat burner. Vitrix contains various herbs that work to enhance natural testosterone production, which could lead to improved strength gains and increased sex drive and libido.

I'm sure most will probably be familiar with tribulus terrestris to some extent, and if you've read around the site a bit, you'll see that we emphasize scientific research on many supplements, diet pills, and their active ingredients. Obviously, real life situations differ from laboratory conditions, and what results are achieved in a lab may not necessary reflect true circumstances of the real environment we live in. My point here is that, although scientific research are a great starting point in evaluating supplements, it's by no means an end-all-be-all metric to evaluating a particular supplement.

I think that is the case here for Tribulus Terrestris. Read on below...

Tribulus Terrestris in Vitrix

There's always controversy and contradicting advice on the effectiveness of tribulus terrestris. Obviously, the marketing materials you read from supplement makers will tout the effects and benefits of tribulus like it's a miracle herb; and then on the other hand, talking with other like-minded fitness individuals, and just simply browsing bodybuilding chat forums, you'll find a wide range of opinions on the subject, and I'm no exception.

Please keep in mind here, that my take on tribulus is purely personal opinion, and only based on my own past and present experiences of using various tribulus based supplements. It by no means, is a verdict on the effectiveness of the herb.

There are a large number of studies that provide contradicting results on the effectiveness of tribulus. Various studies on rats have demonstrated that tribulus increased testosterone and sexual activity 1, 2 , while other studies found that tribulus had no effect on muscle strength, body composition, exercise performance in human subjects 3, 4. Obviously, taking these studies at face value, the studies involving human subjects would obviously carry more weight compared to the studies involving rats and other animals.

However, from personal experience, and based on user reviews of various tribulus based supplements, I would have to say that tribulus works, but not for everyone. Enough users have submitted positive reviews to show that tribulus based supplements do work. I can say from my past experiences that each time I've take a tribulus supplement, I've noticed a difference - these include increased acne breakouts, and increased libido etc...

As unusual as it may sound, Avena Sativa is actually an oat. This 'oat' has many benefits, and has been used for a long time. Here are some uses: relaxation, anti-depressant, herpes, arthritis, indigestion, wrinkles, hemorrhoids, lower cholesterol and others. What we're really interested in here is how Avena Sativa works to boost our testosterone levels, and help you gain more muscles.

It's not until recent years that Avena Sativa has been found to help boost testosterone and also act as an aphrodisiac. Research have found Avena Sativa works by freeing up testosterone that's stuck to other compounds in your body. With age, more testosterone gets bound, and bound testosterone isn't as effective as free testosterone. So, instead of increasing the amount of testosterone, it makes your available amount of testosterone 'more efficient' so-to-speak.

Eurycoma Longifolia (Tongkat Ali) - Tongkat ali, latin name Eurycoma longifolia, is a root that grows in the rainforests of Southeast Asia. Similar to Tribulus, the herb works by affecting the lutenizing hormones in the body, which signal testosterone production. Various studies in rats have shown Tongkat Ali to increase sex drive and libido. 5

User Reviews of Nutrex Vitrix

We've received numerous user reviews and feedback on Nutrex Vitrix, and it has a 4/5 overall rating from all user reviews. You can read Vitrix user reviews here (opens new window). Many of the reviewers noted the effectiveness of the supplement, noting increase in strength, muscle gains, increased libido, and more aggressiveness. Don't just take my word for it, click the link above and read user reviews posted on our reviews section.

I can confirm much of what various reviewers have mentioned about Nutrex Vitrix. The strength and sex drive increases were noticeable, although I can't say that I felt more aggressive. The Nutrex Vitrix comes in clear caps containing liquid German tribulus. The caps are clear so you can see the black liquid inside.

I would recommend taking the full 6 pills per serving as recommended on the bottle instructions, and as per the bottle instructions, you can also take 6 pills about one hour before sexual activity, you might be pleasantly surprised. =)
