The main ingredients in the natural testosterone booster formula include D-aspartic acid, vitamin D, oyster extract, ginseng, fenugreek, magnesium, vitamin B6, vitamin K2, and zinc. 

The oyster extract does not only do wonders for libido levels, but it’s also one of the best sources of zinc. TestoFuel claims that studies have shown oyster extract to inhibit the process of testosterone converting to estrogen, improving the reproductive function. 

The testimonials for this product are very impressive. Champions such as Mr. Olympia and Robby Robinson swear by this product, and it’s also praised by many all around the world. 

According to a satisfied customer from Denmark, this supplement helped him boost his energy levels, strengthen his sexual desire, and increase his muscle mass in only three months!

This is one of the best testosterone boosters that will help you unleash your inner beast. Beast Sports Nutrition’s Super Test Maximum promises to help customers become the man that they are destined to be.

This muscle-building anabolic blend helps burn body fat while maintaining lean muscle. In recovery, it elevates testosterone levels and detoxifies the kidneys and liver.

The main ingredients in this supplement are also impressive. It contains KSM-66 ashwagandha, bulbine natalensis extract, fenugreek extract, primavie shilajit extract, boron citrate, S7 nitric oxide support, estrogen defense, liver and kidney support, and DHT defense. 

According to Beast, bulbine natalensis helps enhance libido levels by increasing testosterone and decreasing estrogen. Furthermore, fulvic acid is a well-known Ayurvedic natural solution for fertility and vitality problems.

Most user reviews see this product as the best natural testosterone booster, with only three customers rating it with three out of five stars. Most customers praise Super Test Maximum for helping with increasing strength and overall mood levels.

On the flip side, one customer reported not feeling any significant bodily changes, but it’s essential to keep in mind that this person has been using it for only two weeks.

Contents per container: 30 servings per container; KSM-66 ashwagandha extract (600 mg), bulbine natalensis (600 mg), fenugreek extract (300 mg), shilajit extract (100 mg), boron citrate (10 mg), a bioactive-enhanced complex of green tea leaves, turmeric, green coffee beans, tart cherry, broccoli, kale, blueberry (50 mg), Japanese knotweed (200 mg), 3,3′-Diindolylmethane (200 mg), pumpkin extract (200 mg), stinging nettle extract (150 mg), turmeric (100 mg), cranberry extract (100 mg), BioPerine (5 mg).

We were glad to see zinc on the list of ingredients, as it is a mineral known for playing a pivotal role in testosterone formation. Moreover, many studies have shown that vitamin D improves overall testosterone levels in the male body.

As for mucuna pruriens, it gives the body L-dopa, a component that blocks prolactin, or the “girly hormone,” while boosting testosterone levels at the same time. 

Many user reviews claim that there are the best testosterone pills out there. According to Dolph Lundgren, Hollywood legend, this supplement helped him maintain his physical strength, vitality, and overall youthful appearance. 

On the flip side, some customers report mild side effects, including headaches and acid reflux. However, keep in mind that some people do not tolerate particular ingredients and that everybody’s organism is different.

The creators of this testosterone booster have got their buyers covered with a 90-day risk-free guarantee. On the flip side, this guarantee does not cover shipping costs. Also, we highly recommend purchasing this booster on the official website, as many distribute fake products with questionable ingredients.

The crowd favorite—iSatori ISA-TEST GF Testosterone Booster—also made our list.

Although this product is relatively expensive, it does contain some high-quality premium ingredients. It includes tribulus extract, epimedium extract (also known as “horny goat weed,” for improving libido), tongkat ali extract, ajuga turkestanica extract, rhaponticum carthamoides extract, and butcher’s broom extract.

Furthermore, it contains vitamin C, vitamin B6, magnesium, and zinc. Since it contains gelatin, it is unfit for vegetarians.

The user reviews for this best over the counter testosterone booster are predominantly positive. Phil B. says that the product helped him increase stamina and energy levels during workouts, while Jeff J. praises it for how well it works when combined with intense training sessions. 

All in all, we believe this product is worth checking out, especially if you are a die-hard gym goer.

Some of the ingredients responsible for its benefits include tribulus, horny goat weed, and tongkat ali. Not only that, but this supplement also doesn’t contain any soy, dairy, eggs, nuts, or gluten, and it’s suitable for vegans!

Furthermore, many praise this product for having the ability to improve a person’s overall strength and endurance during intense workouts. And although it isn’t rated as the best male testosterone booster on our list, this is still a high-quality natural product worth trying.

It’s no surprise that Nutrex’s T-Up was listed as the best testosterone booster in 2019. This highly potent natural testosterone booster claims to support muscle gain and recovery, and there is a clinical study to back this information up.

According to Nutrex, the study participants experienced a whopping 42% testosterone increase in just 12 days. Wow! 

One of the main ingredients in this testosterone supplement is D-aspartic acid, an ingredient we have previously explained to be highly effective in raising testosterone levels in men. Furthermore, this product contains vitamin B6, folic acid, vitamin B12, and zinc. Since it contains gelatin, it’s not suitable for vegans.

The reviews and testimonials for this product are excellent. The majority of users have rated T-Up with five out of five stars, while only a couple rated it with three. According to the positive reviews, this is a useful supplement with zero side effects. 

Furthermore, another user, Dwight, has been using this testosterone booster for working out, and he claims that he has been experiencing increased stamina and energy during his training sessions. As a result, he is able to train longer and harder without feeling tired. 

Conversely, some customers claim that this product wasn’t as effective as they thought it would be. However, keep in mind that many of these users have only been using this product for a month.

This product can be purchased through retailers like Bodybuilding.com or Nutrex’s official website.

Contents per container: 120 capsules per container; vitamin B6 (2 mg), folic acid (400 mcg), vitamin B12 (6 mcg), zinc (15 mg), d-aspartic acid (3000 mg).

Another best testosterone booster on the market that made the list is Muscletech’s Test HD Hardcore Testosterone Booster, that, believe it or not, claims to boost free testosterone in just seven days.

This powerful natural testosterone booster also claims to boost ATP blood levels and increase total testosterone in healthy men. Not only that, but this potent formula does not require a PCT (no cycling needed).

This relatively inexpensive testosterone booster contains ingredients such as zinc and calcium, in addition to tribulus extract, shilajit extract, boron citrate, broccoli powder, stinging nettle extract, and velvet bean extract. 

Since it contains coconut and is processed in a facility that also processes wheat, it is not suitable for people with coconut allergies or wheat intolerance. 

Most users don’t want a free testosterone booster—they want quality at an affordable price. According to one MuscleTech testosterone booster review, this product helps increase energy levels without causing acne.

This information was backed up by another user who also claims that this booster does wonders for keeping energy levels up throughout the day without nasty side effects. 

Overall, we believe that this is a splendid product for tight budgets looking for a quality booster.

his quality multi-vitamin with nighttime recovery promises to increase testosterone and reduce cortisol and estrogen—safely and naturally. The three main ingredients responsible for the AM blend’s benefits are ashwagandha, ForsLean, and DIM.

The AM blend contains powerful ingredients meant to energize you and get you ready for the day ahead, while the PM blend supports you during nighttime. Not only that, but the PM blend of this best testosterone booster for muscle gain helps you get restful sleep.
