Testogen Review: Ingredients
Testogen contains 11 ingredients common to testosterone supplements, such as D-aspartic acid, fenugreek, zinc, and Korean red ginseng.
Rather than directly providing testosterone, the supplement supports your overall health and the body’s natural production of testosterone. Scientific research links ingredients to effects, though research is often preliminary or inconclusive.
As a result, Testogen, and other testosterone boosting supplements can help improve symptoms of low testosterone, increase sex drive, improve lean muscle mass, and increase muscle growth and energy levels, but the results will vary between individuals.
D-Aspartic Acid
D-Aspartic acid is an amino acid that increases levels of luteinizing hormone. Luteinizing hormone directly affects testosterone synthesis, so it is thought to stimulate testosterone production [1].
In researching for our Testogen review, we found that D-aspartic acid has also been shown to increase sperm quality, although these studies have only been conducted in animals [2].
Fenugreek Extract
Fenugreek contains soy saponins, plant-derived compounds that prevent the conversion of testosterone to estradiol. While all free testosterone in the bloodstream is broken down and converted at some point, delaying this process improves overall levels [3].
A 2020 study on the effects of fenugreek showed that the supplement has a clinically significant effect on total serum testosterone levels. This study was conducted using a small sample size, so more research is needed to provide definitive evidence [4].
Zinc
Testosterone deficiency is directly correlated with zinc deficiency. Studies show that men with normal testosterone levels also have significantly higher serum concentrations of zinc, so it makes sense that zinc supplementation might help increase testosterone production [5].
Vitamin D3
Several human and animal studies show that vitamin D status impacts the production of sex hormones. However, it’s unclear whether it plays a direct role in testosterone production. At a minimum, it does have a stimulatory effect on testosterone production [6].
While vitamin D may not directly increase testosterone levels, vitamin D deficiencies can create a host of health issues. Decreased energy levels, higher percentages of body fat, and mood changes are all vitamin D deficiency symptoms.
Korean Red Ginseng Extract
This herbal extract is believed to improve sexual performance, enhance libido, and boost testosterone levels. Some studies also show that ginseng improves sperm production [7]. Unfortunately, the quality of these studies is limited and more investigation is needed to draw any firm conclusions.
While researching this Testogen review, we found the effects of Korean red ginseng may be determined by external lifestyle factors, like diet and exercise. A 2020 study showed that the extract decreased testosterone levels immediately after resistance training. This could be due to the stress hormone cortisol, produced in large concentrations following intense exercise [8].

Boron
Boron supplementation has been shown to increase free testosterone levels after resistance training. Studies have shown results in healthy males taking 6 mg of boron daily for at least one week [9].
Magnesium
Supplementation with this natural mineral shows potential for increasing free and total testosterone levels. While these increases occur in all males who regularly supplement with magnesium, more significant increases occur in men who exercise periodically [10].
BioPerine 95% Piperine
BioPerine is commonly known as black pepper extract. Regular supplementation with BioPerine is reported to increase the body’s ability to absorb nutrients and increase their bioavailability in the bloodstream.
When writing this Testogen review, we saw this compound is included as a way to increase the supplement’s effectiveness and boost its absorption. Unfortunately, the only supplement studied in combination with BioPerine supplements is iron. Black pepper extract does increase the absorption of iron in the body by making it more bioavailable.
While more research is needed on the absorption of other nutrients, the results are promising [11].
Vitamin K1
Vitamin K deficiency has been linked to decreased testosterone production in animal studies. Recent studies show that dietary supplementation with vitamin K inhibits inflammation and helps the body maintain adequate levels of testosterone [12]. Vitamin K1 appears to be one of the essential vitamin K compounds in the production of sex hormones.
Vitamin B6
Vitamin B6 increases the body’s sensitivity to testosterone and other anabolic steroids. Animal studies show subjects with a diet deficient in vitamin B6 show a significant reduction in blood concentrations of testosterone. Subjects supplemented with vitamin B6 significantly increased testosterone uptake, along with prolonged retention of the hormone in the bloodstream [13].
While more research is needed on the effects of vitamin B6 on testosterone concentrations in humans, preliminary research indicates that B6 supplementation is associated with increased sensitivity and response to testosterone therapy.
Nettle Leaf Extract 4:1
Nettle leaf extract plays an indirect role in increasing testosterone levels. Nettle roots contain lignans that bind to the sex hormone binding globulin (SHBG). While this doesn’t increase testosterone concentration, it does increase the amount of testosterone available to use by the body.
Research shows supplements containing nettle leaf extract can improve athletic performance and increase lean muscle mass. This is thought to be due to the greater availability of testosterone in the bloodstream [14].

Does Testogen Really Work?
Based on our Testogen review research, we saw the official website offers over 80 scientific studies to support its effectiveness. However, there are some limitations to the research.
All studies reference the individual ingredients in Testogen rather than the unique combination contained in the formula. While most results are promising, more specific studies on testosterone boosters are needed to prove their efficacy.
Most studies are only conducted on animal subjects, so the results aren’t always applicable to humans. Another concern is the age of the studies. Approximately one-third of the research is over ten years old, with one study over 40 years old, dated 1981 [15].
Our Testogen review research also led us to cite a concern. Many studies are conducted using men with illnesses or specific vitamin and mineral deficiencies. This means the results may not be relevant to individuals without these conditions.

Testogen Customer Reviews
Testogen reviews are mixed, but most report that taking Testogen increases energy. Others report no difference at all from taking the supplement.
Testogen Results: What to Expect
This Testogen review wouldn’t be complete without mentioning benefits. The primary benefit of taking Testogen is increased testosterone levels. Assuming that the product does so, you can expect to receive all of the benefits associated with healthy testosterone levels.
Testosterone is the primary male sex hormone, and it regulates several functions within the male reproductive system. Free testosterone levels affect libido, bone density, fat distribution, lean muscle mass, strength, and sperm production. Testosterone booster supplements are often taken to enhance workout performance and lose weight and body fat.
Increased testosterone levels have also been shown to improve symptoms of erectile dysfunction and elevate mood, indicating that there may be improvements in overall mental health as well.

How To Take Testogen Testosterone Booster
Testogen is available in capsules and booster drops. The recommended dosage is four capsules daily before eating. The booster drops can be used one to three times per day to deliver immediate results and enhance the efficacy of Testogen capsules.
According to our Testogen review research, supplements like Testogen work best when taken regularly over several weeks or months to allow the ingredients to build up over time. It is recommended to take Testogen for at least 30 days to see full results. The Testogen booster drops can be used as directed to see results sooner.

Testogen Review: Side Effects
As of our Testogen review’s writing, there have been no reported side effects from anyone taking Testogen. However, some of the ingredients can cause certain effects.
Side effects related to Testogen’s ingredients include:
- Fenugreek can cause nausea and vomiting. When taken in large doses, there is a risk of low blood glucose levels.
- Zinc can interfere with the absorption of antibiotics.
- High ginseng doses can cause sleep disturbances, headaches, and loss of appetite.
While the FDA warns against using testosterone products to treat low testosterone levels, Testogen does not contain any testosterone. It is a natural supplement designed to trigger your body to produce testosterone on its own, so this warning doesn’t necessarily apply.
Our Testogen review research also shows that excessive dietary and herbal supplements can cause drug-induced liver toxicity. This occurred primarily in individuals with pre-existing liver disease, but it’s worth noting that most toxicities occurred when supplements were used in conjunction with other medications.
If you are on prescription medications or are taking other dietary supplements, consult a health professional regarding any potential interactions.
Testogen Review: Contraindications
In writing our Testogen review, we also included possible contraindications. Testosterone supplements, including Testogen, are not recommended for men diagnosed with breast cancer or prostate cancer.
While this recommendation has been standard practice for decades, contemporary literature has shown that moderate increases in serum testosterone levels have no impact on prostate tumor progression.
Other research advises extreme caution as the studies surrounding T-supplementation in men with prostate cancer have small sample sizes. A follow-up investigation is needed before changing current recommendations.
Popular Alternatives to Testogen
In this section of our Testogen review, we show popular alternatives to the testosterone supplement. None of the following supplements claim to reverse symptoms of clinically low testosterone levels. If you are suffering from low testosterone, this may be better treated using prescribed testosterone replacement therapy.
