Tribulus Terrestris is a vine plant that grows in moderate and tropical climates in the United States, Mexico, Eastern Europe, India and China. It is used as a tonic and aphrodisiac and known more widely for it's perceived ability to increase levels of the male hormone 'Testosterone'. Testosterone is known for its ability to build muscle and to increase fertility and libido. Our Tribulus comes to you in the rawest possible form and the reason for this is simple; too much refinement will undermine it's powerful properties. You have two choices in our range of Tribulus, our famous liquid form; it tastes terrible but doesn't everything that is good for you! Or if you are after something a little easier on the taste buds you can opt for our Tribulus tablets containing Wild Yam and Epimedium. Both the liquid and the tablets come in a 80 tablet/80 day supply.
