Can someone help me explain (to my buddy) how Tribulus terrestris and Avena sativa increase Testosterone levels. He says that taken oraly they are absorbed, broken down and passed by the liver. I’ve taken Tribex for 1 year and can feel it works ;o) just not “how it works” Thanx Mike

Tribulus stimulates the hypothalamus to release a gonadatropin releasing hormone. The gonadatropin releasing hormone (lutenizing hormone releasing hormone) then travels to the anterior pituitary where it stimulates the release of lutenizing hormone. It is the lutenizing hormone that travels to the testis and tells them to produce more testosterone.
