bulgarian tribulus - Personal Trainer Community - Forum

Tribulus Terrestris is a plant that grows in many tropical and moderate areas of the world. Many different cultures have used it for a number of conditions and studies have shown it to be a potent supplement that allows the body to naturally increase tesosterone possibly allowing for greater muscle growth, increased strength and stamina. And it is also useful in personal trainers

I'd be very interested in seeing those studies you mentioned on tribulus. I reviewed tribulus for the book I wrote on dietary supplements and could not find any that showed it raised testosterone levels in humans or animals (studies have been done on this issue). I likewise could not find that it had any use in humans and currently don't see a reason why personal trainers would use /recommend it.
I am always willing to learn so please post the studies you mentioned here (study titles, names of the authors and journals where they were published) so I can obtain them and review them.

Joe a friend of mine just told me about Tribulus by showing me his Arnold S. Encyclopedia of working out. In fact that passage that was stated by Abuzar is almost exactly the same passage from the Encyclopedia. My friend seemed pretty confident that Tribulus is all natural and not synthetic like most test boosters. He said it would be much easier for the body to break down considering it's a plant.

the arnold encylcopedia is not a clincial study. I read the scientitific studies on tribulus when I wrote my supplement book and the research does not show it works. Here is one of those studies

Antonio, J et al. (2000). Effects of tribulus terrestris on body composition and exercise performance in resistance-trained males. International Journal of Sport Nutrition and Exercise Metabolism, 10,2,208-215.

Bottom line to this study-it doesnt raise testosterone or improve strength or burn body fat. (I may have this study on my computer if you want to read it. just email me)

I dont want to dissagree withe the Governator but the science just doesnt back up its claims. this stuff was all the rage in the 90s and seems to be making a come back. incidentally if you've seen the commercials with smiling bob (male sex pill) it has tribulus if I remember. no studies on people that it increases sex but I found one study in rats... so for lab rats maybe for us... not so sure...
I recommend you read my book on supplements. its at my website. It has no hype but just the facts (and side effects of supplements). If you do, hold off for about a month because Im updating the book now with new information.

Speaking of Enzyte:

On August 27, 2008 Enzyte front man, Steven Warshak, was sentenced by U.S. District Judge Arthur Spiegel to 25 years in prison and ordered to pay $93,000 in fines. His company, Berkeley Premium Neuraceuticals, along with other defendants, was ordered to forfeit $500 million. His 75-year-old mother, Harriet Warshak, was sentenced to two years in prison.[7][8]

Here's the Wiki:

The Take-a-way? If it sounds too good to be true, it is! Someone is always trying to make a buck, especially in the loosely regulated (almost NON-REGULATED) supplement industry!

Dave thanks for the heads up on Enzyte! I had not heard about that!

Tribulus has yet to conclusively prove to increase free testosterone levels in resistance trained individuals.

Products that have peer reviewed evidence that may be of more benefit to increase either Growth Hormone or Test levels are:

Alpha-glycerylphosphorylcholine (A-GPC)
Good study by Tim Zeigenfuss demonstrating a significant improvement in GH levels.

Beta alanine has demonstrated in numerous studies to reduce the production of hydrogen in the muscle allowing for reduced fatigue during strength training.

Glycine Propionyl L Carnitine showing some nice data on improving NO levels as well.

You can email me for the paper if needed at tpiattoly@charter.net

Thanks.
