 Tribulus 625 from Optimum Nutrition


Optimum Nutrition's Tribulus 625 is powered with a super potent extract of the Tribulus terrestris plant. The herb tribulus has long been used in traditional medicine to treat a variety of health conditions such as low testosterone levels, impotence, infertility and depression. Tribulus 625 is standardized to 40 percent of physiologically active furostanol saponins (protodioscin and protogracillin). Research suggests that Tribulus' saponins boost testosterone levels by stimulating the anterior pituitary gland. This promotes the production of Leutinizing Hormone (LH), which increases unbound, free-testosterone levels.

Top athletes and bodybuilders have used Tribulus as an effective anabolic (muscle building) agent to raise testosterone levels, increase muscle mass, enhance strength and support athletic performance. Independent studies suggest that Tribulus extract increases testosterone and can promote healthy blood pressure and sexual health.

One study involving 212 men suggests that tribulus supplementation supports healthy libido (sex drive), healthy cholesterol levels and improved mood. No adverse side effects were noted. Since testosterone levels peak in early adulthood and then progressively decline with aging, tribulus may help aging men regain a leaner, more muscular physique and improve sex drive.


Optimum Nutrition's Tribulus 625 is a non-androgenic, non-hormonal formula that supports natural testosterone levels without the use of prohormones. Tribulus can be safely used without the hormonal side effects associated with other testosterone boosting supplements.

The nutrients in Tribulus 625 have the following benefits:

  • Boosts natural testosterone levels
  • Promotes lean muscle mass
  • Enhances muscle tone and strength
  • Improves sex drive
  • Supports athletic performance


Research suggests that tribulus is safe with few side effects. However, pregnant or lactating women, men under the age of 18, or those with a serious medical condition should not supplement with Tribulus 625

Be aware that some drugs may interact with Tribulus 625 including:

  • Antidepressants (such as MAO inhibitors)
  • Stimulants
  • Allergy medications
  • Medications for high blood pressure
  • Medications for heart conditions
  • Diuretics
