NOW Sports Tribulus Terrestris is a single-ingredient herbal supplement: 500 mg of tribulus terrestris extract per capsule, 100 capsules per bottle, gluten free and marketed for energy and testosterone support. Tribulus is a traditional herb, not a proven testosterone booster; most clinical trials in healthy men show no meaningful rise in testosterone, so treat the label claims as marketing rather than established effect. It suits lifters who want a low-cost herbal add-on and are comfortable with modest, unproven benefits. Against multi-ingredient test boosters it is simpler and easier to dose, but it offers no supporting ingredients such as zinc, magnesium or vitamin D.
