Tribulus Terrestris – Testosterone Booster, but not for Muscle Growth

Tribulus terrestris is a flowering plant in the family Zygophyllaceae, native to warm temperate and tropical regions of the Old World in southern Europe, southern Asia, throughout Africa, and in northern Australia. It can thrive even in desert climates and poor soil.

Dietary supplement

Tribulus terrestris has long been used as a tonic and aphrodisiac in Indian ayurveda practice, where it is known by its Sanskrit name, “gokshura”.

It is now being promoted as a testosterone booster for the purpose of building muscle and increasing sex drive. Independent studies have suggested that Tribulus terrestris extract does increase testosterone levels, though leaving them in the normal range, which is not thought to increase muscle development.

Some have compared the tonic properties of Tribulus terrestris to the effects of ginseng, but these occur due to entirely different mechanisms. Claims have been made that it enhances testosterone levels by increasing luteinizing hormone (LH) levels. LH is responsible for “telling” your body to produce testosterone. One interesting fact is that extended use of anabolic steroids reduces levels of LH, thus reducing and sometimes shutting down the body’s production of testosterone.

It is also claimed that Tribulus terrestris increases testosterone by increasing gonadotropin-releasing hormone (GnRH) which in turn stimulates the production of LH and follicle-stimulating hormone (FSH). Testosterone, besides its role in muscle-building and raising fertility and libido, is also known to have a positive effect on bone marrow activity (for red blood cell production) and the immune system.

On the other hand, one recent study found that T. terrestris caused no increase in testosterone or LH in young men, and another found that a commercial supplement containing androstenedione and herbal extracts, including T. terrestris, was no more effective at raising testosterone levels than androstenedione alone. SupplementWatch does not consider that there is any scientific evidence for effectiveness in muscle building. It suggests that it may be beneficial for those whose testosterone is below normal, such as dieters and overtrained athletes.

No significant adverse effects have been reported from supplementation with Tribulus terrestris. However, some users report an upset stomach, which can usually be counteracted by taking it with food.

    No, it is not a steroid, so you should be OK taking it. However, if you are looking to maintain muscle mass, then it may be wisest to just keep working out each week and eating a healthy diet with plenty of proteins.

    I’ve recently ordered a supplement from muscleenhancers.com. The supp I ordered is called “Show-Tech”. It claims to have Tribulus Terrestris in it and also claims to increase testosterone productions by bla bla blah. So far I’ve found nothing to support this claim. Is TT good for muscle building?

    Care has to be taken with any supplement. TT may boost your testosterone and give you an edge, but studies so far have indicated that it does not really help a great deal, and does not push level above normal. If you take any supplement, you still need to workout hard and eat a healthy diet full of lean proteins and salads, pulses etc. You would probably be better off ensuring that your workout is giving maximum gains, and that your diet is perfect.
