True GRIT Test Booster Review

True GRIT Test Booster is, as the name implies, a Testosterone-booster by True GRIT which will be released along with 6 other products including Thermo and Pre…

True GRIT Test Booster



While Fenugreek (as Testofen) has demonstrated the ability to increase Testosterone in one study, it has failed to do so elsewhere under similar conditions. We discuss Fenugreek and its effects on Testosterone in depth in this article.

At this time, the reason for the discrepancy is unknown. So, as a Test-booster, the reliability of Fenugreek should be questioned. Like Tribulus, Fenugreek is an effective libido enhancer and may provide the illusion of increased Testosterone regardless of whether an actual increase occurs.

True GRIT Test Booster contains 300mg of Fenugreek, meaning two servings yields a clinically effective dose.

Broccoli (DIM)

Diindolylmethane (DIM) is a byproduct created during the digestion of Indole-3-Carbinol, a compound found in vegetables such as Broccoli.

A 2011 pilot study found that, when given to human subjects at a dose of 300mg daily for 14 days, DIM produced anti-estrogenic effects.

Under different circumstances, however, DIM has shown the opposite, meaning it actually has the capacity to increase Estrogen.

How is this possible? Well, it’s important to understand that the word “Estrogen” is actually an umbrella term which encompasses several different compounds. Some of these compounds tend to induce more “Estrogenic” effects than others, even though they are all considered “Estrogens”.

DIM appears to increase the level of 2-hydroxyestrogens (“weak Estrogen”), relative to the other types, 16a-hydroxyestrogens and 4-hydroxyestrogens (“strong Estrogens”), the result of which is less of an “estrogen-like” effect, even though total Estrogen (strong and weak) may technically be staying the same.

It’s unclear whether True GRIT Test Booster contains an effective dose of DIM because True GRIT only discloses the total amount of Broccoli extract (250mg).


Ashwagandha is a popular Ayurvedic herb with a relatively wide variety of health implications, ranging from cognitive support to anti-cancer effects. However, in the context of True GRIT Test Booster, the focus is on Ashwagandha’s influence on Testosterone.

A 2010 study, published in Fertility and Sterility”, found that Ashwagandha (5g basic root powder) was able to restore Testosterone levels in infertile men, though subjects did not experience spikes beyond the normal range.

These findings were replicated in a 2011 study in which it was also noted that the effects were more apparent in stressed men (Ashwagandha is a known adaptogen).

There is certainly no reliable evidence to suggest that Ashwagandha can outright increase Testosterone in non-deficient individuals, but research indicates it can help to stabilize/optimize Testosterone, and that this effect is tied to its anti-stress properties.

True GRIT Test Booster contains 125mg of Ashwagandha per serving, not exactly a clinically effective dose.

Shilajit (Fulvic Acid)

Shilajit is a peculiar resin that oozes out of a kind of rock found in the Himalayan mountains.

A 2010 study, published in “Andrologia”, found that 200mg/day of Shilajit (containing roughly 55% Fulvic Acid) was able to increase Testosterone in infertile men after 90 days of supplementation.

At this time no research has been conducted in healthy individuals, so we can’t say with any certainty that Fulvic Acid will boost Testosterone in individuals with normal (healthy) Testosterone levels, but it may be useful for maintaining optimized Test levels. So, in the context of True GRIT Test Booster, it may contribute to the overall effect.


A 2011 study, published in the “Journal of Trace Minerals in Medicine and Biology”, found that boron supplementation (11.6 mg daily) over a one week period was found to increase Testosterone to a statistically significant degree (28%).

An earlier study (1993), found that daily supplementation with 2.5 mg of boron over a 7 week periodfailed to increase testosterone levels.

The obvious reason for the discrepancy is that the 2011 study used 4-5 times as much boron as the earlier study, but more research would be needed to confirm that. True GRIT Test Booster contains 5mg of elemental Boron per serving, meaning two servings yields a clinically effective dose.

Safed Musli

Safed Musli is an Indian herb which has traditionally been used as an aphrodisiac and remedy for sexual dysfunction.

A 2011 study, published in “Andrologia”, found that mice fed Safed Musli experienced improved erectile function on par with low dose Testosterone treatment. No studies have directly tested the effects of Safed Musli on testosterone, but a 2009 study noted increased prostatic weigh in mice fed 200mg/kg/day for 30 days, indicative of increased Testosterone. Unfortuantely, this study did not measure serum Testosterone, so it can’t be definitively stated that the results were due to increased Testosterone.

Due to the lack of human studies, Safed Musli still has a long way to go before it can be considered an effective test-booster, but the preliminary evidence suggests that, at the very least, it may enhance libido and improve sexual health.

True GRIT Test Booster contains 50mg of Safed Musli, not anywhere near the concentration used in the studies above, but not necessarily completely ineffective either.

Gucos Yesiculosus

A 2004 study from “BMC Complementary and Alternative Medicine” found that Fucus Yesiculosus supplementation was associated with a decrease in circulating 17b-estradiol levels. This is thought to be attributed to fucophorethols, bioactive compounds found in Fucus Yesiculosus which possess anti-aromatase properties.

Unfortuantely, no human studies have been conducted in men, so it really isn’t clear at this time how Fucus Yesiculosus may affect Testosterone levels. In the context of True GRIT Test Booster we’d consider Fucus Yesiculosus highly speculative.

Smallanthus Sonchifolius

Smallanthus sonchifolius, also known as Yacon, is mostly used as a digestive-health-aid, but preliminary evidence suggests it may also influence Testosterone.

A recent (2013) study from “Biomolecules & therapeutics” found that 200mg/kg of Yacon extract in (healthy) mice was able to reduce the breakdown of Testosterone, ultimately resulting an increase over the course of 6 weeks of supplementation.

No human studies have been conducted at this time regarding the effects of Yacon on Testosterone and given that the dose present in True Grit Test Booster is only 50mg (compared to 200mg/kg used in the one study), any influence would likely be pretty slight.

The Bottom Line

True Grit Test Booster contains some pretty common alleged test-boosting ingredients as well as some that we haven’t come across in any test-booster before. Overall, the formula does have what it takes to keep Estrogen in check and encourage higher Testosterone levels, but users are not likely to experience any sort of massive Test-boost.
