Tribulus Terrestris leads to the production of the Luteinizing Hormone (LH). When LH levels are increased, the natural production of testosterone also increases. LH is a hormone that also deals with sex drive. Now one can understand why it has been used to increase fertility and reproductive system. Laboratory animal studies found that Tribulus Terrestris increased sperm count as well as motility levels after taking it for 30 days.

Tribulus Terrestris is a testosterone enhancer. This is a good supplement for men and women to increase their sex drive. According to Bill Phillips, editor of Muscle Media, "...Tribulus Terrestris can significantly "lift" performance in the bedroom." Anyone who wants to increase muscle growth (bodybuilders, athletes, etc.) would be wise to try stacking Tribulus Terrestris.

Tribulus Research and Studies

Much studies and research have been conducted, and all have shown positive benefits of supplementing Tribulus Terrestris, and almost no adverse effects. Here are some findings of Tribulus supplementation.

• A study done with healthy individuals taking 1000 mg Tribulus per day showed a 72% LH increase and 41 % in Testosterone increase.
• In a study conducted with 20 males and females, 75% of the participants had increased endurance, 80% had increase in libido and sexual performance, 95% of females responded to PMS symptoms.
• A study conducted with 200 males suffering from impotence showed increase in LH and testosterone levels after supplementing Tribulus. The study also found a increase in sperm count.

The active ingredient in TRIBULUS is unknown, but is thought to be a component known as furostanol saponins. In some cultures, the TRIBULUS terrestris plant has been used as a "tonic" to in crease energy levels and treat sexual dysfunction (for both men & women). In animals, TRIBULUS may stimulate "mounting" behavior. Some European studies suggest that TRIBULUS extract can increase testosterone levels 30-50% above baseline levels - but still well within the normal range. Unfortunately, however, these same studies also suggest a similar increase in estradiol levels - not exactly what the hardcore muscle builders should be interested in boosting.

TRIBULUS extract does indeed elevate testosterone levels somewhat, but keeps them within normal ranges, it may be an effective supplement for individuals with reduced testosterone levels such as athletes at risk for overtraining syndrome and in those individuals on a prolonged low-calorie diet.

This supplement can be taken by both men & women.

DOSAGE: Two capsules twice daily.
