Summary: Test Freak is a testosterone booster that packs in a bunch of ingredients that have limited evidence surrounding their effectiveness at boosting T. Based on my analysis of the research, supplementing with Test Freak will not have a significant impact on your T-levels. 

Verdict: Not recommended. View my rankings of the top 10 test-boosters.

Disclaimer: My review is NOT based on personal experience with Test Freak. Rather, I've gone through the research on each one of its individual ingredients. 

DOES TEST FREAK WORK?

Test Freak contains a bunch of proprietary blends that are NOT proven to impact testosterone levels. 

What really shocked me was the DHT support complex. DHT (dihydrotestosterone) is a hormone that is derived from testosterone but is 3-10x more potent in its effects. Yes, high DHT has been associated with hair-loss, but all the benefits you associate with high testosterone levels have a lot to do with high DHT as well, since the two go hand-in-hand.

The estrogen support complex may help reduce estrogen levels in your body, but the effects have not been studied in humans and only in animal and petri-dish studies.

So to answer the question:

Based on my analysis of the applicable research, Test Freak will not impact your testosterone levels to any significant extent. 

If you want to dive in to the research that led me to this conclusion, then keep reading.

TEST FREAK DETAILED REVIEW

My aim with this review is to provide the information to help you make an informed decision before purchase. 

The main component of this review is the ingredient analysis. Once you understand how each one of the ingredients goes on to affect the human body, you'll get an unbiased view of what the supplement actually does. 

Test Freak Ingredients: 2/5

Test Freak contains a ZMA formula (B6, magnesium, zinc) along with a bunch of proprietary blends.  

The Testosterone Support Complex, DHT Support Complex, and Estorgen Support Complex each include different ingredients that are meant to help with the overall goal of increasing testosterone levels.

Test Freak Ingredients

Vitamin B6

​Vitamin B6, aka pyridoxine, is a B vitamin that has an important role in a number of bodily functions. B vitamins are most known for their involvement in energy regulation, nerve function, and liver health. 

Vitamin B6, particularly, is used by the body in functions such as movement, memory, and blood flow.

Although B6 intake is very important, there are no unique benefits that come with supplementation (1). Also, B6 deficiencies are very rare in the western, developed world. 

The fact that Test Freak provides 525% of your daily requirement for B6 doesn't hurt, but it won't provide any further impact on testosterone levels. ​

Magnesium

Magnesium is a key mineral that partakes in over 300 bodily functions. It is involved in stuff like synthesizing protein, regulating muscle and nerve function, and controlling blood pressure. 

Optimal levels of magnesium are associated with increased energy, a healthy heart, and strong bones. 

When it comes to testosterone levels, magnesium has also been found to be very important. Let's take a quick look at the research:

  1.  After analyzing the blood work of 399 men over the age of 65, researchers concluded magnesium levels to be independently and strongly correlated with testosterone levels (2).
  2. Athletes and sedentary subjects supplementing with magnesium experienced significant increases in testosterone. The increase was greater in athletes (3).
  3. Untrained subjects lifting weights supplemented with 8mg of magnesium per kg of bodyweight. After 7 weeks of supplementation, they gained significantly more strength than placebo (4).

So it's clear that maintaining optimal levels of magnesium is a key component in maintaining optimal levels of testosterone. But also keep in mind that if you're currently getting enough magnesium through your diet, then topping up your levels even more is not likely to impact your testosterone. 

Test Freak provides 23% of your daily magnesium requirement, which is quite a bit higher than some other supplements that I've come across in the past. ​

Zinc

Zinc is another mineral that is crucial for our survival. It plays a part in a number of functions: hormone balance, growth and development, immunity regulation, and digestion are just a few of the many processes it is involved in.

Zinc deficiency is definitely something you want to avoid. If you don't have enough zinc in your diet, then you'll get sick more often, always feel tired, have difficulty focusing, and develop an inability to heal wounds. Although zinc is not a common deficiency in the western developed world, it's still something to keep in mind. 

Let's take a quick look at the research:

  1. Elite wrestlers supplementing with 3mg of zinc per kg of bodyweight for 4 weeks had significantly higher testosterone levels compared to placebo (5).
  2. Sedentary subjects exercising on a stationary bike were given 3mg of zinc per kg of bodyweight. Placebo experienced reductions in T due to the exercise, but the group supplementing with zinc was able to avoid these reductions (6). 
  3. Male patients on kidney dialysis supplemented with 250mg of zinc daily for 6 weeks after which they had significantly higher testosterone levels (7). 

Zinc impacts testosterone levels the same way as magnesium. If your current zinc levels are below the optimal range, then topping them up can have a pretty dramatic impact on T-levels. However, if your current zinc levels are already good, then increasing them via supplementation is not likely to increase testosterone. 

Test Freak provides 200% of your daily requirement for zinc.

Fenugreek

Test Freak contains two trademarked forms of fenugreek: Testofen and Trigotest. I don't know why they included two different forms of fenugreek, and there's not much information about what exactly the difference is, but I'll discuss the impact that fenugreek has on testosterone. 

 Fenugreek is a herb native to India where it has traditionally been used as an aphrodisiac. ​Recently, it has found its way into the ingredient profile in a some of the most popular test booster supplements. But does it actually work? Let's take a look at what the research says: 

  1. Resistance-trained men supplementing with 500mg of fenugreek for 8 weeks had significantly higher testosterone levels compared to placebo (8).
  2. Healthy men supplementing with 600mg of fenugreek for 6 weeks had significantly enhanced physiological markers of libido compared to placebo (9). No significant impact on testosterone levels were found. 
  3. 45 resistance trained men supplementing with 500mg of fenugreek for 8 weeks experienced a decrease in DHT by 9.42% (10). 

We cannot make any conclusions about fenugreek based on these studies, as each of them reveals a different result. The first shows a significant increase in T, the second shows an increased sex drive with no change in T, while the third shows a decrease in DHT. 

More research is needed to explore how fenugreek goes on to affect the human body.

Tribulus Terrestris

Tribulus is a herb that has traditionally been used in India for male health. It is perhaps the most common ingredient found in testosterone supplements today. 

There are a bunch of mixed reviews about tribulus online, but let's get to the root of what it's actually about based on the research: ​

  1. Elite rugby players supplementing with 450mg of Tribulus for 5 weeks experienced no changes in testosterone levels, muscular strength, or body composition compared to placebo (11). 
  2. Healthy subjects were divided into two groups and supplemented with either 10mg of or 20mg of Tribulus per kg of bodyweight. After 4 weeks, no differences in testosterone levels were noted (12).
  3. Infertile men supplementing with 6g of tribulus daily for 60 days experienced improved markers of penile performance as well as an increase of T by 16.3% (13). 

The evidence is pretty clear on this: 

Tribulus supplementation has no impact on hormonal concentrations in humans. So why then has it developed the reputation of being a test booster?

Well the reason is because supplement companies have been using animal and test-tube studies to demonstrate its results and claim that it is scientifically proven to work. But as it turns out, the same results don't carry to affect humans the same way. Obviously they leave that part out. ​

Saw Palmetto Extract

Saw Palmetto is the first ingredient in Test Freak's DHT Support Complex.

As I mentioned earlier, DHT is a derivate of testosterone with 3-10x the potency. Many of the benefits you associate with high testosterone levels can actually be tied back to high DHT levels, since the two go hand in hand. 

Let's take a quick look at the research:

  1. Men supplementing with Saw Palmetto experienced a 32% decrease in DHT after 6 months of use (14).
  2. Men supplementing with 320mg of Saw Palmetto for 3 months were found to have higher testosterone levels but significantly lower DHT levels (15).
  3. Healthy men supplementing with 80mg of Saw Palmetto over a week failed to experience any differences in testosterone or DHT levels (16). 

Supplementing with Saw Palmetto may impact testosterone levels positively, but it does so by inhibiting T's conversion into DHT. This is definitely something we don't want.

Stinging Nettle Extract

Stinging Nettle is a plant that is another common ingredient in testosterone booster supplements.

There's been only one human study using Stinging Nettle and it was performed using patients suffering from an enlarged prostate. Supplementing with Stinging Nettle helped alleviate the symptoms these patients were experiencing, without impacting testosterone levels (17). 

​The one animal study in which stinging nettle was found to boost testosterone was in a rat study in which the rats were already being given testosterone injections. The Stinging Nettle just pushed up their levels a bit more. 

Given that there's been only one human study using Stinging Nettle, and that even on subjects suffering from a condition, we definitely need more research to back up the claims. ​

Hesperidin

Hesperiden is a compound found in orange peels that seems to improve blood flow and has protective effects on the heart and brain. 

It is included as the first ingredient in the Estrogen Support Complex as a means to improve the testosterone to estrogen ratio in your body. As you know, lower estrogen means higher testosterone.

Hesperidein has been shown to have anti-estrogenic effects, but the only research to back this up has been performed in test-tubes or on mice (18, 19), so we can't be sure whether these effects carry on to impact us in the same way.  

(source)

Resveratrol

Resveratrol is the compound in red wine that's associated with better heart health and improved blood flow. 

Once again, no human studies have been performed on resveratrol's interaction with estrogen, but test-tube studies show that it has aromatase inhibiting effects (20). 

Aromatase is the enzyme that converts testosterone into estrogen. Less aromatase means more testosterone allowed to remain in its free form.

HOW DOES IT COMPARE?

For this portion of the review, let's see how Test Freak stacks up against some other test boosters. 

Again, I will go off of the research behind the primary ingredients rather than any subjective measures. 

Test Freak vs P6

P6 Ergogenic Testosterone Booster is manufactured by supplement company Cellucor. 

The primary ingredients in P6 are contained within a proprietary blend of many different herbal extracts. ​Ashwagandha is the first ingredient in the list, which means that it is probably the highest dose. 

Ashwagandha is proven to impact testosterone positively. ​

Even though I wouldn't recommend either of these supplements (because of the proprietary blends), P6 is better in my opinion because of the Ashwagandha. 

Winner: P6

p6

Test Freak vs Nugenix 

Nugenix is a best-selling testosterone booster supplement. 

The primary ingredients in Nugenix are L-Citruline, Fenugreek, and Tribulus.

So the active ingredients in Test Freak and Nugenix are more or less the same, with the exception of L-Citrulline.

I quite like L-Citrulline due to its​ powerful nitric oxide boosting effects. Now, I don't recommend either of these supplements, but Nugenix takes it here in my opinion. 

Winner: Nugenix

Test Freak vs Testofuel

The primary ingredient in Testofuel is D-Aspartic Acid. Like with fenugreek, D-AA is an ingredient that is included in some of the most popular test boosters, but has not been clinically proven to impact testosterone. 

But Testofuel also has a very potent micronutrient formula (including 5000IU of vitamin D) that is proven to impact T-levels positively. So, I'd say that it comes out on top in this case as well. 

Winner: Testofuel

Test Freak vs Animal Stak

​Like with Test Freak, Animal Stak is manufactured by a popular bodybuilding supplement company. They don't specialize in creating hormonal support supplements, but I guess since its a huge market, they wanted to get a piece of the cake as well. 

Animal Stak also contains a bunch of proprietary blends with the primary ingredient coming in the form of Tribulus Terrestris.

Tribulus is included within Test Freak as well, and you already know about the research in terms of its interaction with T, i.e. negligible.

Since Fenugreek has at least one study backing up its testosterone boosting abilities, I'll say that Test Freak takes it in this case. 

Winner: Test Freak

Animal Stak
