A flowering plant called tribulus terrestris is growing all over Europe and Asia.

While it increases users testosterone levels it also increases libido, sperm volume and quality, sex drive. It can also increase aggressiveness. For now, let`s put this aside and talk about the effects in bodybuilding.

Tribulus terrestris become popular in the 70s. It Gained popularity in Eastern Europe first and then the word spread around the globe. It was brought to America by strongman Jeffrey Petermann, looking for new ways to boos training results. It hasn`t left.

It is not really spread to other sports like for an example creatine has. It has staid in the strongman/bodybuilding scene where it has a loyal base of followers and also sceptics.

The bottom line is that it is claimed to increase body`s testosterone levels. But only to the body`s natural limits so it`s often labeled as herbal steroid or safe steroid. This is a far shot, steroids possess far stronger effects on testosterone that tribulus terrestris and therefore pose many dangers. If you increase the testosterone level way over body`s natural limit then in addition to the increased muscle build, also internal organs and pre-cancerous cells will start to grow. So steroid use can lead to permanent damage that tribulus terrestris use can not. Final word about steroids is that many steroid users take tribulus after an steroid cycle to help body recover it`s natural testosterone levels quicker.

Tribulus terrestris contains protodioscin - a steroidal saponin. This is thought to be the working agent. When buying tribulus terrestris keep in mind to buy extract, not plant material as only extract has serious amount of protodioscin. It is considered to trigger the release of nitric oxide in corpus cavernosum tissue, and also to produce statistically significant increases in the levels of the hormones testosterone, dihydrotestosterone and dehydroepiandrosterone in animal studies. Human studies have been few and far apart.

Human studies done suggest that tribulus terrestris exctract does produce higher testosteron levels, sperm quality, sex drive and libido. All of the studies have been done in Bulgaria where also most of the products are done.

A lot of people swear by tribulus. They say that the increase in libido and muscular developement is excellent. There is also a lot of people who say that it does not work.

There might be the answer. Young people`s testosterone levels and sex drive is already to it`s maximum while middle aged men`s testosterone is lacking and tribulus terrestris makes a difference there. It is also said that even when not working out, middle aged men should add tribulus terrestris to their daily diet anyway to keep healthy. Low testosterone levels lead to muscle loss, erectile problems, decrease in general strength. Ingesting few grams of tribulus terrestris daily could help to keep up the quality of life.

As there is no way of over dosing on tribulus then you can take as much of it daily as you see fit. Usually people take over 2 grams daily. I`d suggest that tribulus terrestris extract should be taken before going to sleep so then when body is producing testosterone, it will have a little help. The older you are the more you should take.

You can take all the supplements and steroids in the world but if you do not train hard you will not grow. So hit the squats and everything else HARD!

If you are set on staying natural and off steroids then tribulus terrestris extract really is the only thing besides creatine you can take to really boost the gains. Of course you need to have all your protein and carb and amino acid intake the best possible.Besides this you are in the end of the line for natural bodybuilders.

As with everything in this life there are many haters and many fans. It does rise testosterone levels, but do you really need it to? This is up to you. If you are middle aged then the answer is already yes.
