3. AlphaTest ATP & Testosterone Booster for Men, Boost Free Testosterone and Enhance ATP Levels, 120 Count

Testosterone is the primary hormonal driver of muscle growth. In fact, when it comes to fitness, muscle growth and body composition, normal testosterone levels are essential for you to succeed at your fitness goals. AlphaTest® is scientifically engineered to deliver a powerful testosterone-boosting ingredient matrix to stimulate free testosterone, maintain a peak testosterone-to-estradiol ratio and enhance ATP levels! WHO SHOULD USE IT AlphaTest can be used by active men, fitness enthusiasts and high-performance athletes, powerlifters, crossfitters, bodybuilders, endurance athletes, and men looking to support their testosterone levels within the normal healthy range. INCREASE SERUM TESTOSTERONE LEVELS AND BOOST ATP One of the most exciting key ingredients in AlphaTest® is PrimaVie®, a patented clinical-strength form of shilajit. Shilajit in its natural state has no chemical definition. In order to yield a consistent and efficacious form of shilajit, it is obtained from carefully selected rocks and is put through a patented technology to purify and standardize it. This form of shilajit is now assured of optimal levels of bioactive components such as fulvic acid and dibenzo-pyrones. This rare organo-mineral compound has been shown in clinical research to significantly increase total serum testosterone levels in 90 days. In another study, shilajit was shown to boost ATP levels in just 15 days! ATP is a critical energy source used during workouts. ELEVATE FREE (ACTIVE) TESTOSTERONE AND DECREASE ESTRADIOL Having optimal levels of serum testosterone is important. However, it’s equally important to optimize levels of bioavailable “free” testosterone. Most of the testosterone in your blood attaches to two proteins: albumin and sex hormone-binding globulin (SHBG). Some testosterone is not attached to proteins – it’s "free." Free or active testosterone is the most bioavailable testosterone, meaning it is the easiest to absorb. AlphaTest® is formulated with boron citrate that supplies a precise dose of boron shown in a 2011 scientific research study on 8 healthy male volunteers to significantly increase free (active) testosterone levels and decrease estradiol levels after only 7 days. Reducing estradiol levels is also important, because estradiol is an estrogen that competes with testosterone for receptors in your body. When testosterone binds to an androgen receptor, it activates the receptor and you get the effect you're looking for. Estradiol also looks to bind to these same receptors, and when it does so, it blocks testosterone from binding. Estradiol does not activate the receptor, so nothing happens. With elevated estradiol levels, your free testosterone becomes less effective as too many of your androgen receptors are blocked by estradiol and your free testosterone has nowhere to go. In addition, increased estradiol levels also tell your body to create fewer androgen receptors as cells are replaced through normal regeneration. This is bad news, because in other words, not only does estradiol block the available androgen receptors, but it also causes your body to produce fewer of them in the future. As a result, keeping an optimal testosterone-to-estradiol ratio is vital! PACKED WITH CUTTING-EDGE INGREDIENTS The comprehensive AlphaTest® formula is also packed with additional support ingredients, including Brassica oleracea (broccoli) powder which supplies diindolylmethane (DIM), potent fenugreek extract that is standardized to 50% saponins, and zinc gluconate – a highly absorbable and premium form of zinc. Adequate zinc levels help maintain optimal testosterone production within the normal, healthy range.
