Tribulus terrestris has been used for centuries in ancient Greece, India and Africa to support fertility and rejuvenate the body. Recent scientific studies indicate that, although it actually contains no hormones, Tribulus helps to support healthy hormone production and male reproductive health. Tribulus has been used by some of the world's most elite athletes, but may be used by the recreational athlete as well. Our minimum 45% saponin content makes NOW Tribulus one of the most potent formulas available.

Good but can be better as well!

Tribulus Terretris is known to boost testosterone level naturally without steriods. It is great way to boost muscle, athletic performance, libido, fertility, motivation to work hard, performance, energy level, lift mood, improve concentration and etc. I take it more for the libido boost and I am glad it works well. The minimum 45% saponin ensures that it’s high potency. The tablets are vegetarian and large (horse pill size so some people might have trouble swallowing). Note that there is an undisclosed amount of calcium carbonate (worse form of calcium) is in the other ingredients. Calcium carbonate is used as filler or creates bulk in tablets. Considering that the tablet is large, surely they can help to reduce the size by removing the unneces sary calcium carbonate and make it smaller thus making the bottle smaller as well. I would recommend taking 2 tablets daily and it will still last for 3 months. Pricewise, it is very cheap! It is best to take breaks from this in order to maximise the boosting effects.
