Tribestanol is a non-hormonal phytochemical preparation which may have an effect on the hormonal balance in the body. In males it helps optimize Lutenizing Hormone and Testosterone, while in women it helps optimize FSH ( Follicle Stimulating Hormone ) and Estradiol while only mildly effecting Testosterone levels. Simultaneously, these supported hormonal levels also help support sexual function and libido. In helping to support Testosterone, Tribestanol has shown a general stimulating action such as motor activity, muscle tone, restorative tonic for vigor, vitality and stamina. For this reason Tribestanol is suitable and successfully applied in bodybuilding and other strength sports such as sprinting and weight lifting. Toxicological studies, teratogenic and carcinogenic investigations have concluded the material used in the Tribestanol product has a very good tolerance and no undesired side effects. An important feature in the pharmacodynamics of Tribestanol is the evidence that it regulates the body hormonal balance without any interference with its functional mechanisms. What this means is that there is no aromatization to other hormones because of an imbalance and increase in testosterone. Because of its safety and desirable benefits, this is great dietary supplement for every level of physical activity.
