How Does It Work?

TestoGen works by stimulating the production of testosterone in your body, naturally. Furthermore, it helps free up testosterone and slows down the conversion of these male hormones into estrogen.

Here’s how that happens:

This booster’s D-aspartic acid increases the luteinizing hormones and testosterones within 2-3 weeks. Furthermore, zinc, vitamin D, and vitamin K prevent your testosterone-forming Leydig cells from oxidative damage. As a result, these cells continue producing male hormones flawlessly.

As you grow older, more of your testosterones are bound by the sex hormone-binding globulin (SHBG) – a protein that prevents male hormones from working naturally.

TestoGen’s natural ingredients free up your testosterone from SHBG, allowing you to feel more energized, physically as well as mentally. Additionally, it aids muscle growth, speeds up the fat-burning process, and improves your mood.

Did you know your testosterone converts into estrogen as you get older? TestoGen helps slow down this conversion, letting your T levels stay high despite your age.


TestoGen is easy to administer as you just have to take 4 capsules of the supplement each morning. Another option of consuming this is by opting for TestoGen drops to experience an energy kick on the go.

How Does It Work?

From enhanced cognitive functions to boosted energy and muscle strength, Prime Male helps improve your overall well being faster! Its ingredients are carefully decided to provide all-round benefits by addressing three of the biggest testosterone production problems.

D-aspartic acid calcium chelate—a primary amino acid in Prime Male helps boost the luteinizing hormone (LH). This further increases your T levels by producing testosterone in the testes. Additionally, zinc too aids the production of LH, further enhancing your T levels.

Another essential function stimulated by Prime Male is decreasing the sex hormone-binding globulin (SHBG) from your bloodstream. SHBG binds the testosterone in your body, making them completely inactive. Prime Male consists of magnesium and nettle root that helps release the bound testosterone, allowing them to be used by your body.

Your testosterone levels may also reduce due to high estrogen and prolactin levels. These are female hormones, which may lead to lower testosterone levels if present in high quantities. Boron, luteolin, and mucuna pruriens help curb the presence of these hormones in the male body.

Besides, Prime Male also aids fat-burning, sexual performance, clears up brain fog, and lifts your spirits.


The recommended dosage of Prime Male is 4 capsules a day. However, you must not take all of them at once. Try taking one pill with every meal or a glass of juice at intervals of 3-4 hours. One bottle of the supplement contains 120 capsules, so it should easily work for a month.


Uses twelve 100% natural ingredients

Helps increase testosterone levels by stimulating natural production in the body

Ideal for men aged 30 years or older

Requires you to take 4 pills per day

Offers worldwide shipping with secure payment methods

Buyer’s Guide For Best Natural Testosterone Booster

That was an impressive list of the 5 best natural testosterone booster supplements, wasn’t it? Each of these products is highly rated by users, which is why we bring you detailed information on them. Are you still confused about which is the best one from the mentioned boosters?

Well, here is an informational guide to help clear all your testosterone supplement-related doubts.

Does A Natural Testosterone Booster Really Work?

Natural T-boosters do not raise your T levels all of a sudden. If you see any brand making such claims, know that it is a scam. Legit supplements composed of natural ingredients that boost your T levels organically, which takes time. So, yes, they do work, but rather slowly.

Each of these drugs has a unique combination of various ingredients that instill the process of natural testosterone production in your body. While D-aspartic acid boosts hormone growth in your body (including testosterone), vitamin B6 ensures you do not face a testosterone deficiency.

Besides, you need an ample amount of both vitamin D and vitamin K to ensure steady testosterone levels in your body. That is because their deficiency may reduce the levels of testosterone. Furthermore, items like fenugreek and red ginseng significantly enhance your sexual performance. That is apart from adding to testosterone production.

Other ingredients like nettle leaf and magnesium help release testosterone from the sex hormone-binding globulin that deactivates your current testosterone.

All in all, natural testosterone boosting supplements show significant results due to their pure composition. They contain the right blend of ingredients that work synergistically to improve your T levels.

What are the Benefits of Natural Testosterone Boosters?

You have heard a lot about how T-boosters work naturally, but you still cannot make up your mind. Are you still skeptical about spending your dollars on the best natural testosterone booster? Well, you will not be once you go through these fantastic benefits of a natural testosterone booster.

Muscle Mass Development

You may not be able to identify health setbacks, owing to low testosterone levels, but your body can. Boosters help increase the level of the male hormone in your body. As a result, you can quickly gain and build muscle mass with a rigorous workout. Moreover, this improvement also makes you stronger so you can reach your body goals effortlessly.

Aids Weight Loss

Believe it or not, but low T levels make losing weight relatively challenging. As a result, it gets difficult to maintain the physique you had in your younger years. Balanced or high testosterone levels let you shed off the extra pounds with greater ease. Additionally, you can work better at the gym, which further aids weight loss.

Improves Sexual Performance

Some individuals may lack interest in sexual activities, while others may perform poorly in bed. All of this is due to decreased testosterone levels. One of the prime benefits of high testosterone is improved sexual functionality and drive. Therefore, taking these boosters can help you get back in the field and perform as excellently as before (or even more).

Enhances Overall Mood

The right balance of testosterone in your body will keep you happy and satisfied, day in and day out. High T levels induce feelings of happiness and let you exercise easily. In turn, your body releases mood-enhancing chemicals like dopamine that keep your mood light and fresh.

Boosts Energy Levels

One of the first benefits that you will notice after consuming testosterone boosters is high energy levels. In fact, users report this improvement within 1-2 weeks of consuming natural boosters. That is because the natural ingredients in testosterone supplements help you regain your stamina and boost your energy levels.

Side Effects of Natural Testosterone Boosters

No drug can have only positives and no negatives, except natural products, and testosterone boosters contain only natural ingredients. However, these ingredients might also have a few minor side effects depending upon their suitability with your body.

Besides, these drugs are manufactured in FDA-approved facilities, so rest assured that they will not harm you. Still, a few minor side effects may be:


Oily skin

Hair loss

Mood disturbance

Increased red blood cells

Who Are Natural Testosterone Boosters For?

Testosterone boosters are natural products and, thus, safe for anyone to use. However, there are still a few cases where you should not take these testosterone supplements.

In case you are 18 years or younger

If you are on a severe medicinal course

In case your testosterone levels are already high

If you face any other medical conditions (consult with a doctor before taking these)

Now that you are clear about who should not take these pills, check this outline of conditions wherein you must take testosterone boosters.

Reduced Muscle Mass

Do you think your muscle mass is reducing significantly? Perhaps, you don't see the gains despite a highly nutritious diet and regular workouts. If you have any such indications, chances are you have low testosterone levels. In such a case, opting for a natural T-booster is your best bet.

Fat Accumulation or Difficulty in Weight Loss

Another sign of reduced testosterone level is fat accumulation. In case you are facing challenges shedding those extra pounds, you must instantly start taking testosterone boosters. These boosters help regain the lost energy and improve T levels that aid weight loss.

Reduced Libido Levels

Do you face problems like erection dysfunction (ED)? Are you experiencing a lack of sex drive? Low testosterone levels can considerably lower your libido levels, which can further cause stress and anxiety.

Poor Sexual Performance

If you cannot perform well in bed or sustain an erection for long enough, you might have low testosterone levels.

FAQs About Testosterone Booster Supplements

Q. Is it safe to consume a natural testosterone booster?

Natural testosterone boosters contain only natural ingredients instead of chemicals (that show instant results but are harmful). These ingredients include amino acids like D-aspartic acid, vitamins D3, B6, and K1, and multiple natural extracts.

As far as you are not allergic to any specific ingredient, the natural T-booster is completely safe for you. Therefore, you must thoroughly check the product composition before starting your course.

If you have a severe health condition or are taking some medication, you must consult your doctor before consuming these pills.

Q. How long does it take to see the results from a testosterone booster?

Most natural testosterone boosters claim to start showing effects within a week’s time. However, these are primary improvements in the form of boosted energy levels and enhanced mood. You will begin to see more significant results only after around two months of regularly using these pills.

That being said, improvements in libido and sexual drive usually take anywhere between 3-6 months. However, it is well worth the wait since these boosters are all-natural, unlike chemical shots.

Q. Is a natural testosterone booster useful for women?

Doctors do not usually recommend testosterone boosters for women as high T levels may have some severe side effects. These include unwanted hair growth, enlarged clitoris, etc.

That being said, there are some rare cases where consuming natural testosterone boosters may be beneficial for women. If you have reduced sex drive, suffer depression or fatigue after menopause, and estrogen therapy does not help, testosterone boosters can help.

Q. How can I raise my testosterone levels naturally?

Each T-booster has a distinct composition of natural ingredients. Therefore, you cannot follow the exact dosage for every supplement. The best way to administer these drugs is by following the dosage instructions mentioned on the package or the official website.

That being said, the best natural T-booster brands recommend 4 capsules per day. Though most of these pills come with dosage directions of 4 tabs in the morning, some can be taken at intervals.

In Conclusion - Which Natural Testosterone Booster Supplement Should You Prefer?

That was some detailed information on natural testosterone boosters, wasn't it? But it is indeed necessary to have all your doubts cleared before you opt for a supplement. From its composition to effects and cost to customer reviews, you have to consider multiple aspects thoroughly.

Besides, you cannot just opt for a supplement that has perhaps helped your friend. That is because you may have different requirements and allergic reactions. The best way is to compare the aforementioned best natural testosterone booster options and pick the one that meets your needs precisely. Like we did and found TestoPrime and TestoGen to be the top two best natural T-boosters.

Now that you have everything you need to know, grab the most suitable testosterone booster and watch incredible results!
