Take 250 to 750 milligrams of unrefined tribulus daily with food. According to Dr. Ray Sahelian, side effects of tribulus are uncommon at doses below 500 mg daily.

Ray Sahelian recommends that his patients take tribulus for no more than two weeks at a time and cycling off for an equivalent period of time.
