Tribulus is sheer crap. Even if it did work it would only help you get your test level back to normal if it was low to begin with. Stop reading all the B.S. ads out there on how Tribulus, horny goat weed, wheat grass or any other crap got someone huge. It's all about "selling" you a product. If there ever was a product that actually did raise your natural test effectively then it would sell itself and would also NOT be over the counter. Amen.
