EVL Test is EVLution Nutrition’s test-booster which contains just four key ingredients…FIND IT HERE
D-Aspartic Acid has become extremely popular as a Test-booster in recent years, with research suggesting it is indeed effective, at least in the short term.
A 2012 study from “Advances in Sexual Medicine”, the subjects of which were infertile men (initially low Testosterone) found that 2.66g of D-Aspartic Acid was able to significantly increase Testosterone levels when measured after 90 days of supplementation. These results were in-line with those of an earlier study from 2009 in which D-Aspartic Acid supplementation raised Testosterone by 42% after 12 days in healthy men (initially normal Testosterone).
However, a 2013 study published in “Nutrition Research” found that athletes who supplemented with D-Aspartic Acid for 28 days showed no difference in testosterone levels.
The researchers in the failed study noted abnormally high levels of D-Aspartate Oxidase, the enzyme which degrades D-Aspartic Acid, indicating that prolonged supplementation in individuals with healthy Testosterone levels may cause “negative feedback”.
In the context of EVL Test, D-Aspartic Acid may serve as a means of increasing Testosterone in the short-term, but this short-term boost is likely to fade in individuals with initially healthy Testosterone levels.
Tribulus has a well-documented history of use as an aphrodisiac and overall vitality booster, but as a Testosterone booster it has failed to live up to the hype.
A 2005 study, published in the “Journal of Ethnopharamcology” found that 200mg daily (60% saponin content) had no effect on Testosterone in healthy men.
These results were replicated in a 2007 study in which 450mg of Tribulus extract daily failed to influence Testosterone levels in male athletes.
Even a 2012 study, this time testing the effects of 6g of Tribulus extract on infertile men, found a less than significant trend towards increased Testosterone.
The research is pretty clear about Tribulus: it won’t boost your Testosterone levels beyond the normal range. It may enhance libido, mimicking the partial effects of increased Testosterone, but will not induce Testosterone-like gains in strength and lean mass. EVL Test contains 750mg of Tribulus which has become a sort of industry standard (the term “clinical dose” doesn’t really apply here).
Fenugreek has become one of the most popular “natural” Testosterone-boosters out there, so we had a feeling we’d end up seeing it in the EVL Test formula. 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. EVL Test contains 500mg, yielding 250mg saponins (bioactives), which is actually a clinical dose.
Diindolylmethane (DIM) is a byproduct created during the digestion of Indole-3-Carbinol, a compound found in vegetables like Broccoli which is also pretty common in test-boosters these days.
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 possibly? 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.
The Bottom Line
EVL Test definitely has what it takes to encourage a favorable hormonal environment although how much it will actually increase Testosterone depends on the individuals initial Testosterone levels (i.e. low vs. high). The formula does contain clinical doses of key ingredients, so assuming it’s priced similar to competing products, EVL Test is a pretty solid option.
