"You're an extreme athlete with hard goals. An athlete who brings a level of gritness to everything you do. For the days you drove through a blizzard to get to the gym...for the times you trained legs when everyone else was training chest...for the nights you trained back when you had the flu. We salute the iron warriors who are a 10 on the scale of gritness. It's for trainers like you...who fight adversity with everything they do...that we made True Grit™ supplements. To give you the edge you need to dig deeper and get grittier!"


True Grit™ is raw, unadulterated power born from advanced supplement research. True Grit™ was created using some of the most impressive scientific studies ever completed in the world of sports nutrition – clinical studies performed at leading universities and sports performance labs around the globe.* These studies represent a database of the most effective physique-altering and performance-enhancing ingredients currently available, and now, we bring them to you, as the most science-based, research-backed, fully disclosed and results-oriented supplements available.* Supplements that let your true grit show through from the gym…to the streets.


The all-new True Grit™ Test Booster is scientifically engineered to deliver the most powerful 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 balance.* Using powerful clinically studied key ingredients, True Grit™ Test Booster works with the body to naturally support testosterone levels while staying within the normal healthy range.*


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 underdosed 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 miniscule amounts of 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.*


Support 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.*

Support Free Testosterone and aid in Lowering Estradiol*

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 suggested in human clinical research to support free testosterone and aid in decreasing estradiol.* 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 powerful compound that has been suggested in human clinical research to support healthy cortisol balance. 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.*

Formula Breakdown


Trigonella foenum-graecum, also known as Fenugreek, is an annual leguminous herb that belongs to the Fabaceae family. It is grown extensively and is native to many Asian, Middle Eastern, and European countries.

What’s more, it has a long history of use as a traditional herb and continues to garner the interest of researchers around the world for its potential biological effects.

The Fenugreek used in True Grit™ Test Booster is standardized to 50% saponins.


Brassica oleracea (broccoli) powder extract supplies diindolylmethane (DIM). This nitrogen containing compound continues to be the focus of modern research. It is one of the many organic molecules in cruciferous vegetables being investigated by scientists because of its complex interactions in the body with downstream target proteins.*


PrimaVie® is a patented clinical-strength dose of shilajit, which is a rare organo-mineral compound obtained from steep rocks of different formations found in the Himalayas and other high mountains. Shilajit is obtained from carefully selected rocks and is put through a patented technology where it is purified and standardized in order to yield a consistent and efficacious form.* As a result, only PrimaVie® contains optimal levels of bioactive components such as fulvic acid and dibenzo-pyrones.*

The Fenugreek used in True Grit™ Test Booster is standardized to 50% saponins.


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.


Chlorophytum borivilianum, popularly known as Safed Musli, is an important herb in the Ayurvedic Materia Medica.



Yacon is a fiberous tuber that supplies FOS (fructooligosaccharides) and phenolic acids such as, chlorogenic acid, ferulic acid and caffeic acid. In emerging pre-clinical data, Yacon tuber extract and chlorogenic acid showed a significant inhibition effect of testosterone degradation.*


Bladderwrack, also known as Fucus vesiculosus, has garnered the attention of scientists investigating its potential for supporting healthy hormone balance.*

I have been taking this product for almost 2 years, and it has helped me increase my testosterone levels. To understand it your testosterone can be measured with a blood test. mine was low on the total testosterone and the free testosterone. i saw an increase in the total testosterone from the 37 percentile to the 67 percentile within 18 months. the Free testosterone went from the 25 percentile to the 61 percentile compared to my age group. I like this product, is not a miracle drug that one day to the next you will gain tons of testosterone. it has the ingredients that your body needs to produce testosterone.

Great energy, i take this once daily with my MuscleTech Platinum multi's, and MusclePharm's Fish Oil. I have sustained energy, great sleep, and powerful sustained strength. Everyone here that has commented about is not working don't understand that a booster will not take affect until at least 2 months later (or 45 to 60 days). People tend to have the common misconception that once you drop it down your gullet it's going to have some magical instantaneous effect.

This by far the worst supplement I ever use it smells and it taste awful had a hard time swallowing the pills because there where to big and had a bad after taste. The results at the gym where none well working out after taking the supplement my stomach just did not feel right. I use the product about a month with no results.

I agree with dheck26, this product stand alone or with Glute and PWO, BCAA and still no gains after 45 days. My "libido" has actually gone down...you know when you take something new you get excited thinking alright another good product to aid in my lifting and gains. NOT with this. Weak at best. Try at your own money risk.
