Tribulus Terrestris Extract

  • Support Natural Testosterone Production*
  • Increase Lean Muscle Naturally*
  • Support LH Production*

Tribulus terrestris is a vine plant that is native to temperate climates in areas of Southern Europe, Southern Asia, Australia, and Africa. It has a long history of uses, from promoting muscle development to supporting overall health. Tribulus has been suggested to stimulate levels of testosterone and luteinizing hormone (LH), while simultaneously supporting energy levels, recovery time, and muscle gain. This effect is claimed to be mediated via steroidal saponins within the Tribulus, which allegedly block central testosterone receptors. The active compound in Tribulus is the saponin, protodioscin, which is similar in structure to dehydroepiandrosterone (DHEA).*

Many clinical studies involving Tribulus terrestris consumption in humans have produced equivocal results in regards to the effects it has on testosterone and LH levels. Regardless, Tribulus terrestris has been advocated to promote optimal hormonal levels that can potentially establish the anabolic environment necessary for muscle gain and development.*
