Question

Are testosterone booster dietary supplement products safe and effective?

    OPSS Answer

    These products contain ingredients such as Tribulus terrestris, Eurycoma longifolia (Tongkat Ali or Longjack), maca, yohimbe, arginine, and epimedium (horny goat weed). They claim to increase male sexual hormones such as testosterone, which affect muscle strength, endurance, and male sexual performance, but there is insufficient evidence to support this claim. Testosterone-booster dietary supplements are not drugs and should not contain drugs, but they fall in the class of high-risk dietary supplements, and FDA has found that they often contain undeclared drug ingredients, anabolic steroids, or “designer steroids” that are illegal.
