Athletes and bodybuilders often turn to sports supplements for improved results. Testosterone boosters are supplements that may help athletes build increased muscle mass and strength. Testosterone boosters such as tribulus terrestris, DHEA and the mineral compound ZMA may help your body produce more of the male hormone testosterone. Keep in mind that testosterone boosters are not regulated by the Food and Drug Administration and may be unsafe for certain populations including women and adolescents.

Muscle Gain

When used in conjunction with a resistance training program, testosterone boosters may speed muscle gain. During training, muscles sustain microscopic tears which are rebuilt during rest. Increased testosterone speeds the rate at which muscles can be rebuilt, allowing athletes to work harder in the gym without overtraining. However, it is unproven that testosterone boosting supplements raise testosterone levels high enough to increase muscle gain.

Improved Motivation

One of the more common anecdotal reports from testosterone boosters is that they increase aggressiveness and motivation during workouts. If an athlete is motivated to train harder, than it is likely that they will experience faster progress. However, testosterone’s role in aggression may be exaggerated, and that those reporting more aggressive behavior may in fact be experiencing a placebo effect

Improved Sexual Function

Testosterone boosters like the herb Tribulus terrestris may play a role as a natural remedy for impotence and fertility. Increased testosterone levels are known to improve sexual arousal, especially in older men and post-menopausal women. Natural testosterone boosting supplements are thought to signal your body to produce more of its own testosterone, which may increase sexual arousal and fertility simultaneously. Consult with your doctor before using a testosterone booster for infertility or impotence. Testosterone boosters are not meant to replace prescription medications for this purpose.
