Are testosterone booster dietary supplement products safe and effective?

    OPSS Answer

    These products contain ingredients such as tribulus terrestris, yohimbe, arginine, and epimedium (horny goat weed). They are purported to increase levels of hormones, including testosterone, luteinizing hormone, dehydroepiandrosterone (DHEA), and dihydrotestosterone, which explains why such products are often used to enhance muscle strength and athletic performance as well as counter male impotence, although their mechanism of action remains unclear. Many so-called “testosterone “boosters” are not drugs, but some of them are (or contain) testosterone-derived “designer” steroids and are actually illegal. For more information, read HPRC’s Dietary Supplement Classification System: Testosterone Precursors/Booster and Anabolic Compounds. Testosterone boosters fall in a class of high-risk dietary supplements that the FDA has often found to contain undeclared drugs, which could cause issues with drug screening. For drug testing results related to dietary supplements, see HPRC’s Dietary supplements and drug testing.
