What’s your gritness?



The all-new True Grit Test Booster is scientifically engineered to deliver the most potent testosterone-boosting ingredients on the market today. This powerful 3-in-1 formula offers the benefits of both free and total testosterone boost as well as cortisol suppression. Using powerful clinically studied key ingredients, True Grit Test Booster works with the body to naturally increase testosterone levels while staying within the normal healthy range, so no PCT is required!



Dramatically Boost Serum Testosterone

One of the researched key ingredients in True Grit Test Booster is PrimaVie® (shilajit). This rare organo-mineral compound is obtained from the steep rocks of different formations found in the Himalayas and other high mountains! The shilajit in True Grit Test Booster is assured of optimal levels of bioactive components such as fulvic acid and dibenzo-pyrones. This powerful test-boosting compound is shown in a human clinical study to significantly increase total serum testosterone levels as documented after 90 days.


Increase Free Testosterone & Decrease Estradiol in 7 Days

Most of the testosterone in the blood is bound to a protein called sex hormone binding globulin (SHBG). Your free testosterone isn’t bound into anything, so it just circulates in your veins and can be instantly utilized by your body, which makes it very effective. So you could have very high levels of total testosterone, but if all of that testosterone is bound to SHBG, your benefits won’t be so great as the testosterone wouldn’t be in constant use by your body.

Fortunately, True Grit Test Booster makes full use of science in this regard, and includes a clinical dose of a chemical compound called Boron. Boron has been shown in human clinical research to increase free testosterone and decrease estradiol in just 7 days. With True Grit Test Booster, you not only get the ingredients you need to free up bound testosterone, but you also get the estradiol-lowering advantage to ensure your free testosterone can get the job done.

Decrease the Cortisol to Testosterone Ratio

Cortisol is the main stress hormone in the body and when it’s elevated has a catabolic (muscle breakdown) effect on tissue and is associated with a decrease in anabolic (muscle growth) hormones like IGF-1 and GH. With the body in a catabolic state — it starts breaking down muscle and storing fat!

To combat this, True Grit Test Booster has a researched dose of Sensoril® Ashwagandha (Withania somnifera), a potent compound that has been shown in human clinical research to significantly lower serum cortisol levels. Reduced cortisol levels help put your body in a more anabolic state and supports optimal testosterone levels, which is ideal for building muscle and strength.

Sensoril® Ashwagandha (Withania Somnifera) is a potent adaptogen that has been scientifically shown to significantly lower serum cortisol levels. High levels of cortisol are counterproductive to your gains because it’s a catabolic hormone, which can lead to muscle breakdown. In just one 60-day double-blind placebo controlled study involving 98 subjects using the same amount of Sensoril® Ashwagandha (Withania somnifera) found in True Grit Test Booster, researchers discovered that subjects experienced a reduction in serum cortisol.

True Grit supplements have absolutely nothing to hide. That’s why there are no proprietary blends in any True Grit product. Proprietary blends are used by some brands to hide that they are using under-dosed levels of premium ingredients. That’s not what True Grit is about. True Grit supplements contain premium, fully-dosed key ingredients, so you’ll know exactly what is in the supplement you’re putting in your body. You won’t find ineffectual doses of any ingredients in our products because we know that you don’t want to pay for a product that isn’t going to work. That’s what other brands expect you to do if they’re using minuscule amounts of key ingredients just to claim it’s on the label. With True Grit you can trust that you’re getting only the best supplements formulated using the best scientific research.
