WHY CHOOSE THIS TESTOSTERONE BOOSTER

TO NATURALLY INCREASE YOUR TESTOSTERONE LEVELS?

Most other Testosterone-boosting supplements do not provide 1500 mg of clinically proven ingredients formulated exclusively to both increase Testosterone levels as well as stop the depletion of this key male hormone. Most other Testosterone-boosting supplements do not contain Tribulus Terrestris, Zinc & Tongkat Ali served in a potent daily dose for incredibly fast effective results. Most do not contain a clinically proven ZMA blend of Zinc, Magnesium & Vitamin B6 to stimulate Testosterone production. Most don't have a synergistic blend of herbal ingredients for enhancing Testosterone levels including Red Clover, Fenugreek and Mucana Puriens. Most do not include BioPerine® (Piperine) for increased bioavailability and speeding up results. The truth is that most Testosterone supplements do not live up to their claims. Most do not have the potency needed. And most contain ingredients such as unnecessary proprietary blends, additives, preservatives, fillers or binders.

Due to extensive research and our firm understanding of what makes an effective Testosterone supplement, we have created a product that is uniquely formulated to provide the ultimate triple-action formula to stimulate the synthesis of Testosterone, free up bound Testosterone in order to increase the amount of active Testosterone in the blood as well as to block the conversion of Testosterone into dihydrotestosterone (DHT).

Each ingredient was carefully selected, based on years of research and clinical studies. Over 20 years of safety and efficacy research has been documented on what ingredients should be included in a quality Testosterone supplement to get the very best results possible with absolutely no side effects.

In terms of quality and purity of ingredients, there is nothing else on the market that comes close to Approved Science ® Testosterone Booster.

  • Red testosterone molecule structure and label.

    STEP #1 SYNTHESIZE

    Testosterone is the key male sex hormone which wanes in men starting from age 30. This can cause a low libido, a lack of sex drive, an inability to perfom and even depression. Tribulus Terrestis is shown in clinical studies to increase Testosterone levels and improve sex drive. Tongkat Ali is used to boost libido and improve male fertility. Mucuna Pruriens contains a precursor to the hormone promoting Testosterone production.

  • Human torso with highlighted heart and blood vessels.

    STEP #2 UNBIND

    Vitamin D has been studied to release Testosterone which is bound to sex hormone-binding globulin (SHBG). Bound Testosterone is biologically inactive and cannot affect body cells. Once it is unbound, Free Testosterone circulates in the blood and is responsible for health benefits such as boosting libido, sperm production, muscle mass and bone density.

  • Needle points to low on a testosterone level gauge.

    STEP #3 SUPPORT

    Fenugreek and Red Clover prevent Testosterone from being converted into DHT resulting in more free Testosterone in the blood. Research on Zinc has shown that as its level rises, so do Testosterone levels. Zinc, Magnesium and Vitamin B6 work together to ensure the proper balance of free Testosterone in the blood.

  • Cross-section of a healthy blood vessel.

    STEP #4 BOOST

    Results are seen even faster due to the BioPerine® that is added to the formula. BioPerine® is designed to ensure that the benefits of all the natural ingredients are felt sooner and stronger to ensure maximum effect and healthy Testosterone levels.
