Tribulus Terrestris P.E.40%
Tribulus terrestris has long been a constituent in tonics in Indian ayurveda practice, where it is known by its Sanskrit name, "gokshura."
It is now being promoted as a booster for the purpose of increasing sex drive. Its use for this purpose originated in Eastern Europe in the 1970's. It was popularized in America by 1970's strong-man Jeffrey Petermann. Independent studies have suggested that Tribulus terrestris extract slightly increases hormone levels, though leaving them in the normal range.
Some have compared the tonic properties of Tribulus terrestris to the effects of ginseng, but these occur due to entirely different mechanisms. It is also claimed that Tribulus terrestris increases testosterone by increasing gonadotropin-releasing hormone with gonadotropic adaptogen compound containing Tribulus terrestris (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 known to have a positive effect on bone marrow activity (for red blood cell production) and the immune system.
The active chemical in T. terrestris is likely to be protodioscin (PTN), a cousin to DHEA. In a study with mice, Tribulus was shown to enhance mounting activity and erection better than testosterone cypionate. This however, is not as convincing as one might think. Although an OTC supplement outpacing a pharmaceutical is big news, testosterone cypionate is a synthetic ester of testosterone engineered for its longer activity. To be effective, its level must build up in the system of the animal using it.
