AI Sports Nutrition TestoPRO XT is an all natural testosterone-booster that uses only the most scientifically proven ingredients to elevate testosterone levels. You can expect more strength leading to heavier lifts, more muscle mass increase, lots of natural energy, and a libido that will go absolutely through the roof.
TestoPRO XT is the culmination of several ingredients, proven by science to be beneficial in raising testosterone (Testofen, and Divanil), naturally, as well as other ingredients proven by science to promote positive estrogen modulation towards the beneficial metabolites (Indole-3-Carbinol).* And finally, two ingredients that have been shown to aid in the absorption and bioavailabity of the package as a whole (Quercetin, Bioperine®).
Testofen is an extract of fenugreek seed containing the steroidal saponins, sapogenins and furostanol saponins, which are important precursors for the synthesis of a number of sex hormones. This extract has been proven in human studies to raise free testosterone (the biologically active form) by an amazing 98.81 percent.*
Divanil is a compound tried, tested and scientifically proven to enhance free testosterone by binding to sex-hormone binding globulin (SHBG). SHBG keeps your testosterone bound, and by adding in Divanil, much more testosterone is free in your system, and you can reap its positive effects.*
Indole-3-Carbinol is a compound found in high concentrations in Brassica family vegetables, including broccoli, cauliflower, brussels sprouts, and cabbage. Indole-3-Carbinol has several effects, ranging from anti-cancer, to anti-oxidant, and finally the reason AI included it in this formula - estrogen modulation. Metabolism of estradiol results primarily in either 2-hydroxyestrone or 16a-hydroxyestrone, and to a lesser extent 4-hydroxyestrone. It is known that 16a-hydroxyestrone causes proliferation of some breast tumor cell lines, while the alternative metabolite, 2-hydroxyestrone, demonstrates anti-estrogenic and anti-proliferative activity. Indole-3-Carbinol helps the body to modulate estrogen to degrade into the healthier of the alternatives, as opposed to the other.
