Although such products are typically combinations of ingredients that include tribulus, rather than tribulus alone, the scientific evidence for product effectivenenss is typically lacking. At this time, Supplement watch does not view tribulus extract ( on its own) as a valuable dietary supplement for muscle building. As a support ingredient contained in a wider supplement blend, tribulus may provide some benefits to those individuals interested in maintaining testosterone levels in the normal range (overtrained athletes and dieters). Tribulus terrestris extract can produce statistically significant increases in levels of testosterone, dihydrotestosterone and dehydroepiandrosterone, and produces effects suggestive of aphrodisiac activity. On the other hand, one recent study found that T. Terrestris caused no increase in testosterone or LH in young men, [9] and another found that a commercial supplement containing androstenedione and herbal extracts, including T. Terrestris, was no more effective at raising testosterone levels than androstenedione alone
