In humans, testosterone functions as a sex hormone. Although both sexes secrete it, most of it is found in male reproductive organs, specifically the testicles. The production of testosterone influences physical attractiveness, sexual maturation, sperm production, and a man’s desire to have sexual relations. According to a 2008 study,[1] the decrease in testosterone secretion is frequent in older men. More than half of males over 80 have low testosterone levels. Men may also have low testosterone levels if they suffer from hypogonadism, also called testosterone deficiency syndrome. However, you can treat low testosterone in a variety of ways. The use of herbal and dietary supplements like Testogen that promise to increase testosterone levels in those with the illness is rising. In our Testogen reviews, we will analyze its functions, components, health benefits, how to take it, potential side effects, and much more.

How Does It Work?

The manufacturer claims that the combination of these 11 ingredients in Testogen can benefit men’s health. 

Testogen has “little to no clinical data proving their usefulness,” says Jillian Kubala, MS, RD. Due to insufficient evidence supporting its effectiveness, Kubala does not advocate Testogen or similar supplements.

While “the dosages utilized are far lower than the levels believed to be beneficial,” there are components in Testogen that have been shown to aid with low testosterone levels.

Examples include fenugreek, one of the herbs in Testogen, with only little evidence that it can raise healthy testosterone levels in men. Even though it has been shown to have positive effects in some research, the 40 mg dose present in the supplement wouldn’t impact the average user much.

A 2017 study came to the same conclusion as the 2010 study cited above, finding that 500 mg of fenugreek significantly can boost testosterone levels in subjects.

Testogen Ingredients List

The manufacturers of Testogen claim that the product contains ingredients that have been medically shown to efficiently and safely enhance testosterone levels.

D-aspartic acid, an amino acid, is the main ingredient in Testogen. It stimulates the pituitary gland to produce luteinizing hormone (LH). Both sexes produce LH, but only males’ testes are affected by it. When released, it causes testosterone production to increase. The amount of D-aspartic acid in Testogen is 2,352mg.

There are also 200 milligrams of magnesium in Testogen. It has been suggested that magnesium, one of the most common elements in the human body, may improve athletic performance, combat depression, and reduce blood pressure, among other benefits.

Magnesium has been shown to improve physical function in males with magnesium deficit and testosterone shortage in both observational and intervention trials.[2] However, the findings may not apply to males with average or elevated magnesium or testosterone levels.

Fenugreek is a herb used in Indian cooking and traditional Chinese medicine to treat skin issues, and Testogen contains 40 milligrams of this extract. Breast milk may be a healthy choice for infants, and preliminary evidence suggests it may also improve men’s testosterone levels and libido.

A 2010 study[3] showed that 500 mg of fenugreek seeds increased lower and upper body strength in males who frequently engaged in resistance exercise, while additional research is needed to conclude how fenugreek seeds affect testosterone synthesis.

Testogen also contains zinc, vitamin D3, Korean red ginseng extract from Korea, boron, nettle leaf, vitamins B6 and K1, and BioPerine (a type of black pepper).

D-Aspartic Acid

As an amino acid inhibitor of luteinizing hormone production in the pituitary gland, D-aspartic acid (DAA) is crucial to testosterone production. Testosterone is produced by the Leydig cells in the testes in response to the luteinizing hormone; therefore, one may expect an increase in testosterone levels if DAA levels were raised.

Clinical investigations in rats led to studies in human athletes showing that D-aspartic acid supplementation increases testosterone concentration. Unfortunately, humans complicate things a little bit.

DAA supplementation has impacted strength gain but not basal or free testosterone levels in a few modest clinical trials. Furthermore, additional research has shown that DAA raises low testosterone levels in sedentary males.

More research is needed to clarify DAA’s true efficacy as a testosterone-level enhancer, but regrettably, this misinformation is typical in the natural supplement sector. Those with low testosterone levels are more likely to benefit from DAA, while those with normal or above-normal levels will see less increase.

Fenugreek Extract

Fenugreek extract contains many beneficial compounds; one of these compounds stimulates testosterone production. Saponins in the extract block the conversion of testosterone to estrogen. Inhibiting this conversion allows natural T levels to be restored while also countering the effects of elevated estrogen, making it simpler to lose body fat and gain quality muscle.

In contrast to many other herbal extracts, fenugreek has substantial scientific support, making it one of the few ingredients with medically tested effects on low testosterone levels in men. According to a recent meta-analysis of multiple clinical studies, the total testosterone serum concentration in men is affected by fenugreek extract.

Vitamin D3

Your skin converts ultraviolet light into vitamin D3, a natural fat-soluble vitamin your body makes. Normal immune function and calcium and phosphorus absorption regulation are two of vitamin D’s primary roles.

Increased fatigue, bone weakness, muscle pain, and osteoporosis are all shockingly common symptoms of vitamin D deficiency. Low vitamin D levels have been linked to low testosterone and a weakened male reproductive system.

Testogen Review: What Do Real Users Say?

There are a LOT of testosterone-boosting supplements out there, so I did research before buying any. Normal testosterone levels in men my age should be between 300 Ng/dL and 900 Ng/dL…mine was at 256 Ng/dL. Before trying testosterone injections (which can cause serious side effects), I first wanted to try a non-prescription supplement.

After taking them for 2 months, my levels went from 256 ng/dL to 352. There is also plenty of research that shows Testogen to be one of the most effective testosterone supplements.

A key thing to remember is that it will only raise t levels in men who have low levels. It’s not going to make you ripped, it’s not going to make your body transform into a bodybuilder. It just raised levels enough to where I felt more confident and improved my mood, my facial hair started coming in thicker again, and I just felt more like a man than an introverted boy like before.

Testosterone is the hormone that makes men manlier, while estrogen causes feminine characteristics. So if you’re looking for a supplement to turn you into a bodybuilder, you will be disappointed. If you want to feel more confident and more assertive and “manly,” then you will be satisfied with the results in my opinion.

Nathan in the United States of America

Hello. I’m a 35-year-old male. Recently, I’ve noticed decreased energy levels, decreased libido, and overall lower energy. I read many positive reviews about Testogen online so I figured I would try it. I’m on my third day and I’ll tell you what: This stuff is amazing. I already feel more energetic, and more focused, I’m sleeping much better at night and my libido has already dramatically improved. No wonder you guys get away with charging $60 a bottle. This stuff works! Just wanted to say thank you.

Chris in the United States of America

I like the product. I’ve only noticed subtle changes as I’m not taking a full dose. I only do one tab a day. Didn’t notice anything at all until after my second week. Maybe that’s because of the dosage. No complaints. I will continue to use this product and I may up my dosage on my second go around.

Is Testogen Safe?

While Testogen is relatively safe when used according to the dosage, some of the components in Testogen may be dangerous especially when combined with other drugs. For example, the supplement’s ingredients list includes Korean red ginseng, which is known[4] to have negative interactions with many regularly used drugs.

Keep in mind that the FDA has not approved Testogen or any other dietary supplement (FDA). marketed as a safe and natural approach to enhance testosterone levels, there is no research backing this claim.

Is Testogen A Steroid?

One cannot classify Testogen as a steroid. The supplement claims to be made from “100% natural components,” yet little clinical data supports its usefulness or safety.
If your doctor determines your low testosterone levels, they may suggest another testosterone therapy. Remember that these drugs are not the same as steroids. Misuse of anabolic steroids has been linked to endocrine disturbances, such as low testosterone levels.

Where To Buy Testogen?

If you want to buy Testogen, your only option is the manufacturer’s website. You can save money by buying bulk and knowing you’re getting a genuine product. Testogen can be tried without danger because the website provides free international shipping and a substantial refund policy.

Recommended Dosage

It is recommended that four Testogen capsules be taken in the morning, 20-30 minutes before breakfast. Testogen capsules are recommended, but the manufacturer also suggests using the liquid Testogen Instant Booster Drops, which give you a burst of energy and stimulate your body to produce testosterone to get the full benefits.

Final Thought

Low levels of the male hormone testosterone are quite prevalent. However, due to a general lack of data, we do not advise utilizing testosterone-boosting pills like Testogen to treat the issue.

Instead, you can try taking natural supplements that have been shown to help with low T symptoms and are backed by science. Other effective testosterone therapies include regular exercise, reduced excess weight or belly fat, and adequate sleep.

Frequently Asked Questions

How long do testosterone boosters take to kick in?

The producers of Testogen state that within 2 weeks, consumers may begin to see relief from low T symptoms. However, there is an absence of reliable clinical data to back up these assertions.
However, you may start noticing improvements with testosterone replacement therapy as soon as three to four weeks. According to a 2011 analysis of credible sources, optimal benefits may not be seen for 9-12 months.

How can I boost my testosterone naturally?

Your doctor may prescribe testosterone replacement therapy drugs if your T level is 300 ng/dL or lower. Some lifestyle changes may also help increase testosterone levels.

Can Testogen be used with pre-workout supplements?

Testogen’s all-natural components have been shown to increase testosterone production in the body. When combined with other nutritional aids, it causes no adverse reactions. On the other hand, Testogen could potentially interact with your medicine and pose a health risk if you already have a pre-existing medical problem. Using Testogen further necessitates a trip to the doctor to establish the supplement’s safety.

Is Testogen FDA Approved?

No, not at all. The Food and Drug Administration does not yet approve treatment with Testogen for low testosterone levels. Only their manufacturing facility is FDA-approved. Since it’s classified as a dietary supplement rather than medicine, the government doesn’t monitor it.

Does Testogen Increase Size?

Designed to aid in muscle development and growth, Testogen is sold as a nutritional supplement. While there is little feedback concerning this from user reviews, this product’s components have the potential to aid with muscle growth.

Is Sex Hormone Binding Globulin (SHBG) bad for testosterone?

It’s also normal for SHBG levels to decrease with older age as the production of sex hormones also decreases. If your SHBG levels are too high, it likely means that less of your total testosterone is free testosterone that’s available for your tissues to use. So, your tissues may not be getting enough testosterone.
