Tribulus (Tribulus terrestris)

Tribulus grows predominantly in India and Africa, is mentioned in ancient Indian Ayurvedic medical texts dating back thousands of years, and is used widely in the Ayurvedic system of medicine for the treatment of sexual dysfunction and various urinary disorders. It is a natural herbal alternative to synthetic anabolic hormones without any clinically proven toxic effects.

The active ingredient in Tribulus is marketed as Tribestan. Frequent clinical trials and studies have been carried out using this extract. Tribestan has passed all the drug tests at every competitive level and has been used with significant results by top professional athletes as well as by recreational sport participants with no contraindications, no toxicity and no side-effects.

Three major medical centers in Bulgaria have conducted clinical studies on Tribestan’s effect on reproductive functions. In 1981, Tribestan was incorporated into mainstream medical treatment in much of Eastern Europe for improvement of libido and erectile function, increasing serum concentration of testosterone and luteinizing hormone (LH), and stimulation of spermatogenesis with increased concentration of sperm and an increase in sperm motility and viability.

Tribulus appears to raise natural testosterone production in men via the activation of hormone secretion and estradiol. Clinical studies in Bulgaria have shown Tribulus to increase the sex hormones LH level by 72% and the body’s own free testosterone level by 41% in healthy adult males in only five days. LH regulates the testosterone production in the testes and high levels of LH coincide with high testosterone levels.

With its good safety profile and its natural herbal origin, Tribestan is sold as a dietary supplement in many countries with little restriction on its use.
