You may have heard of a natural herb called tribulus terrestris.  I am going to tell you what I have found out about it so far.  Most of the info is really good – there doesn’t seem to be any side effects caused by the plant so it is probably safe to take (of course, always ask your doctor first – but they probably won’t know anything about it).

Tribulus extract is extremely safe and appears to have no undesirable side effects. One of the reasons Tribulus extract doesn’t seem to have any apparent side effects in research subjects is because it doesn’t push testosterone above “upper” normal levels. 
The original purpose for tribulus terrestris extract was as a “tonic” to treat sexual dysfunction.   In animal husbandry studies it was shown to stimulate rutting behavior (what we should do every morning) in rams as well as boars.

Here’s a little from a study that was done…

“When the supplements are taken by men in a dose of 750 milligrams per day for five days, LH and testosterone were elevated 72% and 40% respectively. As you might expect, estradiol was also elevated. In fact estradiol was elevated by 81%! The increase in testosterone is obviously what all the fuss is about, nevertheless, you can’t ignore the fact that whenever you increase testosterone you are going to increase aromatization and therefore estrogen levels. To put these changes in hormone levels into perspective, the reference range for testosterone in men is between 300 – 1,000 ng/dL. The subjects in this study started out with an average of 600 ng/dL and ended up with about 850 ng/dL. This is still well within the “normal” range for men. Estradiol on the other hand went from normal levels of about 76 pg/ml to significantly elevated levels of 137.5 pg/ml. This is well above normal levels which range from about 20-80 pg/ml in men.”

 So – apparently – Tribulus Terrestris does seem to do something.  In other words, it’s not just one of those supplements that MAY do something.  Know what I mean?

 
So, as far as a safe and natural way to increase testosterone, it appears that Tribulis Terrestris does this – at least in some of the studies.

So – where can you get it?  One of the best sources is on the right hand side of this page.     It’s called Testarol.
    
This complex is built upon a base of Tribulus terrestris: 

Skeptics suggest that tribulus may not pack the physiological punch to have a significant or long-term impact on testosterone levels, and manufacturers have sought out other testosterone-boosting supplements to use in conjunction with tribulus.  

What is Tribulus Terrestris?

Tribulus Terrestris is a flowering plant that has many common names like Yellow Vine, Puncturevine and Goathead. It is in the family Zygophyllaceae, and is native to warm tropical regions such as southern Europe, Africa and northern Australia. This weed like plant can survive in poor soil and desert climates as well.

A few of the benefits of Tribulus Terrestris include an improved feeling of well being and athletic performance. Other benefits include increased energy, a healthier sex drive, better appetite and lower body fat levels.

In bodybuilding, Tribulus Terrestris purportedly helps to increase strength and lean muscle mass when using weights to train. It also is said to normalize and promote healthy nitrogen balance, and increases the natural level of testosterone, necessary for bodybuilders.

Tribulus Terrestris has been shown effective for enhancing luteinizing hormone production (LH), which can raise the natural level of testosterone. This has a positive effect on strength and stamina.

Tribulus Terrestris is all natural,  stimulates LH, which in turn signals your body to produce more of it’s own natural testosterone.

Phytochemicals found in Tribulus Terrestris stimulate the production of the hormone testosterone. This hormone plays an important role in building muscles, and stimulates cells to absorb more protein from food. Both are important in bodybuilding.
