Tribulus terrestris is a testosterone booster. Instead of being a testosterone precursor, like prohormones, it 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, so you can see why it has been used to increase fertility and help with impotence.

Tribulus Terrestris is a powerful plant extract, favorable for its ability to greatly enhance LH which signals production of testosterone. Research studies evaluating the results of male subjects taking 750mg per day of Tribulus Terrestris reported a huge 72% increase in LH. Perhaps more importantly, biologically active free testosterone dramatically increased by 41%! What's more, Tribulus Terrestris does not harbour any adverse side effects.
