BSN has introduced a new testosterone-boosting supplement: Evotest.

Evotest is purported to use cutting-edge ingredients to increase exercise and muscle performance, mainly through cutting-edge ingredients like d-aspartic acid and magnesium oxide.

Let’s look at the details to see if Evotest lives up to BSN’s claims.

Evotest Supplement Facts

Here are key ingredients in Evotest:

Vitamin D 400 IU. Vitamin D is usually known for its antioxidant properties, but one study found it also influences testosterone levels in men.

Men with vitamin D deficiencies and low testosterone supplemented with 3,332 IU vitamin D, resulting in a significant improvement in testosterone. Researchers concluded vitamin D may be an effective treatment but advised more controlled trials. [1]Evotest Side Effect

The study used nearly 8 times the amount contained in Evotest; but, the product may still provide testosterone increases.

Magnesium Oxide. Magnesium is well documented to affect testosterone levels. One study tested sedentary individuals and athletes and found 10 mg magnesium daily increased testosterone in both, but greater increases were found in those who exercise. [2]

Evotest claims magnesium oxide, a compound form of magnesium with completely different properties, is a breakthrough testosterone supplement; however, I cannot find any reliable studies showing it influences testosterone levels more than magnesium. [3]

N-Acetyl L-Cysteine. One study found antioxidant defenses, like those from n-acetyl l-cysteine, regulate cell death and promote male germ cell health and longevity. [4]

Another study similarly suggests n-acetyl l-cysteine (600 mg) treats male infertility and low sperm count due to serum testosterone level increases. [5]

It is likely Evotest contains high enough levels of n-acetyl l-cysteine to produce testosterone increases.

D-Aspartic Acid. Researchers who supplemented sub-fertile male subjects with d-aspartate found the amino acid greatly impacts testosterone regulation and treatment of infertility.

Results indicate testosterone levels improved enough to boost the rate of pregnancy among the subject’s partners. [6]

Using 3.12 g d-aspartic acid, males showed increased testosterone release and synthesis. [7]

Evotest may contain enough d-aspartic acid to help regulate and synthesize testosterone.

Evotest Customer Reviews

Most customers seem very satisfied with Evotest, even if they dislike the taste. Here is what real people are to say:


“if you’ve ever wondered what Orange Pine-sol tastes like, this is the product for you.. literally had to gag every ounce of this product down, only taken it one day so I don’t know if the effects are good or not.. but the taste is absolutely horrid..” – avdehe,


“I like this because it doesn’t provide sporadic energy, or get you hyped up like on a sugar rush, but it gives you that natural high you get when adrenaline pumps.” – robin215,


“sry folks, couldn’t even get through one serving it tasted so bad. i’ve choked down all kinds of bad tasting protein, creatine, and other types of supplement powders but this was by the far the worst ive tasted. i was excited about a test booster in powder form because i get sick of taking 4-8 pills a day of the other products. this stuff was just so disgustingly sweet, it’s hard to explain because i’ve not tasted anything else like it. i gave it to my buddy and he couldn’t choke it down either. anyway, i’ve always been a fan of bsn so i ordered the evo-test in pill form.” – uwspmgc,
