Tribulus from NOW foods and Supplementstogo.com.Tribulus terrestris has been used for centuries in ancient Greece, India and Africa to increase fertility and rejuvenate the body. It wasn't until the mid-eighties however, when a team of Bulgarian researchers determined that it may elevate testosterone production by increasing the blood levels of LH (luteinizing hormone) - a testosterone balancing hormone produced by the pituitary gland. The rest is history. Tribulus has been used by some of the worlds' most elite athletes, but is still safe enough for the weekend ironman.
