Summary: Testogen is manufactured by a company of the same name. I have not personally used this supplement, but my review is based on how each of its ingredients go on to impact testosterone. Based on my analysis of the research, Testogen will not significantly impact your testosterone levels.

DOES TESTOGEN WORK?

I never recommend supplements as the sole means to increase testosterone levels. If you're experiencing symptoms of low T, it's likely due to your decisions regarding nutrition, exercise, sleep, and other lifestyle factors. Make sure to optimize these areas before considering any type of supplementation. Your endocrine system is way to complex to be fixed with a simple pill.

But to answer the question:

Based on my analysis of the research, Testogen will not significantly impact your testosterone levels. It has some proven libido enhancing ingredients as well as nitric oxide boosters, but no research solidifies its status as a testosterone booster.

TESTOGEN DETAILED REVIEW

The purpose of this review is to walk you through the research behind each of Testogen's ingredients so that you can make an informed decision before purchase.  

The most important part of this review is the ingredients analysis. Before taking any supplement it is important to understand how the ingredients affect your body. And for that, we need to dive in to the research. ​

Testogen Ingredients: 2.5/5

Testogen Ingredients Label

D-Aspartic Acid

​D-AA is the primary ingredient in Testogen. According to the research, D-AA is an effective testosterone booster for infertile men. If your T is currently within the normal range, then D-AA supplementation can still boost your levels, however the effect is likely to last only up to a few weeks. 

Here's a more detailed look at the studies:

  1. 23 men supplementing with a daily dose of 2g of D-AA over a period of  12 days had 42% higher testosterone levels compared to placebo (1). 
  2. Resistance trained men supplementing with 3g of D-AA over a period of 28 days experienced no changes in body composition or testosterone levels compared to placebo (2). 
  3. Impotent men supplementing with 2.66g of D-AA over 90 days were able to increase T-levels in the range of 30-60% (3). They were also able to increase fertility by 26.6%.

As you can see, the research shows mixed results.

Tribulus Terrestris

Tribulus is perhaps the most common ingredient in testosterone booster supplements. ​It is a potent libido enhancer, but this is not to say that it affects T-levels in the same way. 

Let's take a quick look at the research on tribulus and its interactions with testosterone: 

  1. Elite rugby players supplementing with a daily dose of 450mg of tribulus over 5 weeks experienced no differences in body composition or testosterone levels compared to placebo (4). 
  2. 21 men, aged 20-36, supplemented with either 10mg of tribulus per kg of bodyweight, 20mg of tribulus per kg of bodyweight, or placebo. After 24 days, no hormonal differences were noted (5).
  3. In men with low sperm count, 6g of daily tribulus supplementation for 60 days increased testosterone levels by 16% (6). 

The research is pretty clear on this: 

In otherwise healthy men, supplementing with tribulus has little/no impact on testosterone levels. However, infertile men have been shown to experience a slight increase in T.

That being said, tribulus can contribute to increasing your sex drive.

Panax Genseng (root)

Asian Panax Ginseng has been found to have positive benefits on mood, immunity, and brain function. ​As per its effects on testosterone, let's take a quick look at the research:

  1. 60 patients with low-moderate ED were given either 3g of Korean Red Ginseng (KRG) daily or placebo. After 12 weeks, the subjects receiving KRG reported stronger erections, but T-levels remained unchanged (7).
  2. Men with poor sperm mobility supplementing with panax ginseng were found to have improved markers of androgenic hormones (8).

Although the effect on testosterone seems negligible, Panax Ginseng does seem to be a potent nitric oxide booster (9), i.e. it dilates the blood vessels and improves blood flow.

Fenugreek Extract (seeds)

Fenugreek is another popular ingredient in testosterone booster supplements. It has traditionally been used in Indian herbal medicine to boost libido and masculinity, but let's dive in to what the research says:

  1. 30 resistance trained men were given either 500mg of fenugreek or placebo. After 8 weeks, the subjects supplementing with fenugreek had significantly lower body fat and higher testosterone levels (10). 
  2. 45 resistance trained men were given either 500mg of fenugreek or placebo. After 8 weeks, the group taking fenugreek experienced 9.47% lower DHT levels and no change in testosterone levels (11). 

​DHT is an anabolic hormone with more potent effects than even testosterone. The fact that fenugreek decreased DHT levels in the second study is interesting to note. 

That being said, there have been only two human studies done on the interaction of fenugreek with androgens. Whether fenugreek works or not is inconclusive based on the research. ​

Zinc

Zinc is a key mineral in the human body involved in a variety of antioxidant and immune-boosting functions. It can be consumed via animal products, dairy, and eggs. 

Zinc can significantly boost your testosterone levels (11), but the extent of this increase is dependent on your current deficiency. If you're zinc levels are fine, then topping them up even further will have no impact on T. 

Pyridoxine Hydrochloride (B6)

​Vitamin B6 plays many small key roles in the body, but has not been studied for any particularly unique benefits.

Riboflavin (B2)

Vitamin B2 hasn't been studied for its interactions with testosterone, but should be included as a part of any healthy diet. Most people have adequate levels of B2. and deficiencies are relative rare. But Examine.com recommends people in the UK to supplement with it, since food there is apparently devoid of riboflavin compared to food in US and Canada.

Calcium Pantothenate

Vitamin B5 is a very important vitamin for controlling enzyme function. It is also very important for the upkeep of energy regulation. 

As for deficiencies, they are relatively rare, and topping up levels is unlikely to have any further benefits.

Selenium

Selenium is an essential mineral in the human body for its anti-oxidant properties. There has been some research supporting its positive interaction with testosterone (12), however the impact is not significant.

Cholecalciferol (D3)​

Our skin synthesizes vitamin D upon exposure to sunlight. Vitamin D is also present in foods such as fatty fish, dairy, and eggs. 

Vitamin D is an essential vitamin in the human body and plays a part in over 1000 bodily functions. As it turns out, it is also directly correlated with testosterone levels:

Men supplementing with 3332 IU of vitamin D3 for 1 year had 25% higher testosterone levels compared to placebo​ (13). 

Like other vitamins and minerals, vitamin D will only impact your testosterone levels to the extent that you are currently deficient in it. The impact can be huge, but it can also be negligible if you already have optimal levels. ​

Testimonials: 1/5

Other than on other review websites, I was unable to find any testimonials on Testogen. They don't even have any on their own website.

HOW DOES IT COMPARE?

Now let's get into how Testogen stacks up against some other popular testosterone booster supplements. 

Testogen vs Testogen XR

Testogen-XR and Testogen are made by two completely different companies. I guess neither copyrighted the brand name. 

Testogen-XR is manufactured by Ronnie Coleman's supplement company. The primary ingredient in it is also D-AA. Some other ingredients include  Agmatine Sulfate (nitric oxide booster), AstraGin (anti-inflammatory), Horny Goat Weed, Nettle Root, and L-Carnitine. 

Given that both these products contain the same primary ingredient, they are likely to affect your testosterone levels to a similar degree.

Testogen-XR

Testogen vs Prime Male

The primary ingredient in Prime Male is also D-AA, but there are also a bunch of proven T-boosting vitamins and minerals.

Vitamin D, vitamin K2, zinc, boron, and magnesium are all scientifically proven to support optimal T. 

Some other ingredients include Velvet bean, nettle root, BioPerine (proprietary blend) and ginseng. 

Overall, Prime Male packs a punch of proven ingredients that may be very effective at boosting T-levels. Definitely one of the more superior testosterone supplements on the market. 

Prime Male

Testogen vs Nugenix

Nugenix is the #1 best-selling testosterone supplement on Amazon.com. 

The primary ingredients are L-Citrulline Malate, fenugreek, and tribulus.

L-Citrulline is an ingredient added to many pre-workout supplements for its nitric-oxide boosting properties. As for tribulus and fenugreek, you already know the research behind their interactions with testosterone.

Based on my analysis of the research, Nugenix will not impact testosterone levels to any significant extent. ​

Testogen vs Testofuel

TestoFuel is another best-selling testosterone supplement.

The primary ingredient in TestoFuel is also D-AA. 

The proven ingredient in TestoFuel is vitamin D. As you know, it's proven to boost testosterone levels. And given that Vitamin D deficiency is the most prevelant deficiency, TestoFuel has your needs covered providing 5000 IU of it per serving. 

TestoFuel also contains oyster extract. As you may know, oysters are a rich source of zinc. If your current zinc levels are low, then topping them up can have a pretty dramatic impact on your testosterone levels as well.
