Testo Lab Pro Review: How Effective Is This Testosterone Booster?

Be it the modern diet, today's hectic schedule, quality of food, or stress, testosterone levels in men have been declining for decades(1). The supplement industry is overloaded with anabolic steroids and artificial ingredients that fix something just to break another.

But, Testo Lab Pro distinguishes itself with a novel formulation and 100% natural ingredients packed with minerals and vitamins. We went through all the ingredients to discover if it positively affects testosterone levels, erectile function, muscle mass, energy, and sex drive. 

Can a product with an underdose of D-Aspartic Acid (DAA) and other uncommon testosterone booster ingredients be legit? This is our Testo Lab Pro review that holds nothing back.

What Is Testo Lab Pro?

what is testo lab pro

Testo Lab Pro T-Booster is an all-natural, science-backed testosterone supplement that claims to prevent T level decline and boost it. Manufactured by Opti-Nutra Ltd., it includes essential vitamins, minerals, and herbal extracts.

The team aims to boost 3 decisive masculine forces: testosterone, muscle, and sex. As an updated version of an older product, Testo Pro has some bold claims for men struggling with low testosterone levels:

  • Boost muscle growth and bone strength
  • Enhance athletic performance in both strength and endurance
  • Rev fat loss
  • Increase sex drive, libido, and focus
  • Improve moods and emotional imbalances

But, looking at the ingredients, this testosterone-boosting supplement contains only 600mg of DAA. Most T boosters include twice the dose found in Testo Lab Pro.

The Testo Lab Pro formula doesn't have some common ingredients, such as Fenugreek extract, L-Arginine, or vitamin B6. Let's find out if Testo Lab Pro is just another t booster experiment or a properly naturally sourced testosterone supplement.

How Does Testo Lab Pro Supplement Work To Increase Testosterone Levels in Your Body?

Testo Lab Pro consists of natural ingredients known to increase testosterone levels and prevent elements that contribute to its decline. This product stands out among T-boosters because it contains some ingredients that would be part of any healthy and balanced diet.

how does testo lab pro supplement work to increase testosterone levels

It uses Nutrigenesis to manufacture particular nutrients from natural extracts like yeast. Certainly a better alternative to anabolic steroids and their unpleasant side effects. Also, there is no need to cycle the intake since it's safe to take all year round.

Testo Pro claims to be highly potent and easily absorbed by the body. According to their website, the product has a triple effect on your testosterone levels:

  1. Increases testosterone production through restoring essential vitamins and minerals. Gonadotropin-releasing hormone, luteinizing hormone, and follicle-stimulating hormone will signal testosterone release more efficiently.  
  2. Reduces the level of testosterone killers, such as free radicals, estrogen, hormone-binding globulin and cortisol. It directly fights the conversion of testosterone into estrogen.
  3. Supports enhanced performance and boosts energy levels. All these factors keep the body optimal to produce testosterone at high levels. As they point out, high testosterone levels allow you to train harder, which helps boost testosterone levels more.

Testo Lab Pro Formula - Testosterone Boosting Ingredients

Testo Lab Pro formula is free from GMOs, soy, allergens, gluten, and synthetic additives as well as suitable for vegetarians. Regarding digestion, it deserves an A+. But men interested in boosting their t levels have one question: does it deliver on its promise?

testo lab pro ingredients

Ashwagandha Root Extract (5% Withanolides), 600mg

Few testosterone booster supplements include Ashwagandha, a root commonly used in Ayurveda therapy to boost masculine energy. Often added to stress support supplements, Ashwagandha helps balance cortisol, boosting the hormones necessary for t production.

Research shows that 8 weeks of usage significantly increases muscle mass and strength(2). Another 2019 study found that the intake of ashwagandha extract is associated with increased levels of DHEA-S and testosterone(3).

This supplement packs twice the amount used in the study, so that's a good start. You'll experience lower cortisol levels, better moods, and enhanced energy levels.

Mucuna Pruriens Extract Velvet Bean (15% Levodopa), 300mg

Mucuna Pruriens is an herb used as a male infertility manager and an aphrodisiac. Its main benefit includes an increase in semen volume and quality(4).

This extract signals testosterone release by raising dopamine, adrenaline, and noradrenaline levels(5). Testo Pro's 15% standardization delivers a significant quantity of levodopa (I-Dope) to be converted into dopamine.

Nonetheless, most studies that found Mucuna Pruriens extract beneficial for t levels were conducted on infertile men. Its effects on healthy men and their athletic performance are inconclusive.

D-Aspartic Acid Calcium Chelate - DAA-CA, 600mg

D-Aspartic acid is an amino acid which boosts t levels by raising testosterone production(6). Testo Lab Pro adds Calcium Chelate to DAA, ensuring higher body absorption.

Unfortunately, their dosage is fairly low. Studies show positive effects on the dose of 3gr for inactive men and at least 5-6gr for active men(7)(8).

On the website, Testo Pro Lab highlights that they have research showing that a larger dose of DAA-CA actually lowers t levels. Since their product is evergreen and doesn't need cycling, a lower DAA-CA dose is healthier.

Luteolin extract (100% natural orange), 60mg

Luteolin natural extract comes from orange, and its duty is to stop the conversion of testosterone into estrogen. This extract hinders estrogen biosynthesis by decreasing aromatase release and destabilizing aromatase protein levels.

More than boosting testosterone production, the luteolin extract helps to undermine the loss of it. Among synthetic estrogen inhibitors that other t boosters use, luteolin is a clean and natural alternative.

Testo Lab Pro claims that the dosage also maximizes D-Aspartic Acid's testosterone impact.

Vitamins and Minerals

Testo Lab Pro contains vitamins and minerals to restore and boost testosterone levels. These ingredients are lab-grown through Nutrigenesis - a process that mirrors nature. Thus, the body doesn't receive any artificial ingredients that unnaturally stimulate t production.

  • Zinc, 30mg
best vitamins and minerals that help produce testosterone zinc

As proven by science, zinc supplementation improves athletic performance and prevents exhaustion of total and free testosterone in highly active people(9).

After absorption, zinc also promotes the increase in Luteinizing Hormone levels, which is linked to human growth hormone and free testosterone. Overall, it's a good ingredient, especially for those with deficiencies(10).

No wonder zinc is one of the most prevalent t booster minerals. Some studies even link it with male fertility, although they're conducted on mice(11). This supplement contains enough of your daily zinc intake to fuel your male hormones and help the immune system and metabolism.

  • Magnesium, 50mg
best vitamins and minerals that help produce testosterone magnesium

Testo Lab Pro argues their magnesium dosage increases total and free testosterone count as well as promotes growth hormone production and muscle development.

How does magnesium help? This mineral essentially stops SHBG (Sex Hormone Binding Globulin) from binding to testosterone, which reduces its anabolic efficacy and levels(12).

According to NIH, the optimal daily magnesium intake for adult males should be between 400-420mg(13). Testo Lab Pro contains only 12% of the daily intake, which leaves space to take the mineral through food and other supplements.

  • Boron, 6mg
best vitamins and minerals that help produce testosterone boron
Avocados are high in boron

Boron is not a commonly used ingredient in testosterone boosters. But it has proven to have amazing effects on estrogen and testosterone levels and assisting in the absorption of magnesium and Vitamin D(14).

A study indicated a substantial rise in free testosterone in a week of boron supplementation of 6mg/d(15). By fighting estrogen, boron enhances the male hormone state and boosts testosterone production.

It doesn't stop there, boron was found to help with the growth and maintenance of bones and wound healing(16). Testo Lab Pro has the optimal amount of it, and the evidence speaks for itself.

  • Vitamin D, 50mcg
best vitamins and minerals that help produce testosterone vitamin d

Vitamin D supplementation has direct effects on muscle cells and has been shown to improve muscle strength, especially in the elderly(17).

Although some research suggests that this vitamin increases t levels, others refute it(18). For instance, in a controlled trial, vitamin D supplementation had no effect on t levels in men who were not deficient in it(19).

But, most people have vitamin D deficiencies, so Testo Lab Pro did well to include it in their formula. On the plus side, the vitamin D you'll get from Testo Lab Pro is also almost identical to the one you'll get from the sun rays.

  • Vitamin K1 & K2, 50mcg

You don't see Vitamin K in a lot of the t boosters around. But, Testo Lab Pro states they included it because a low intake may cause a drop in testosterone levels.

Based on our research, all the studies that suggest the same were conducted on rats(20). So, the issue is still unsettled for humans.

Nonetheless, Vitamin K improves the body's ability to absorb vitamin D and helps it perform its function. As we see it, vitamin K functions more as a supportive ingredient than as one directly impacting testosterone production.

Inactive Ingredients

Testo Lab Pro comes in NutriCaps, vegan capsules produced from pullulan (fermented tapioca). The capsules are filled with NuFlow, a 100% natural rice concentrate ingredient. It keeps the product safe and ensures the other active ingredients stay intact.

What’s more, NutriCaps are infused with a small amount of prebiotic nutrition, so no need to worry about your digestive health.

What Are the Benefits of Using Testo Lab Pro Testo Booster?

After age 35, the decline in t levels in men can bring a cascade of other physical, mental and emotional annoyances. Testo Lab Pro is designed to address precisely these issues. It excels at optimizing testosterone levels naturally and is neither aggressive nor too stimulating.

Here's a list of its Pros and Cons:

Pros

  • Increases muscle mass and bone density and strength 
  • Boosts athletic energy and improves body composition
  • Improves male performance at work, bedroom, and gym
  • Enhances focus
  • Helps with recovery

Cons

  • Doesn't provide a potent effect on highly active and healthy individuals

Who Should Use Testo Lab Pro Product?

Testo Lab Pro is formulated for men only. Women shouldn't take this supplement since the DAA-CA might bring severe side effects. 35+-year-old men who struggle with low t levels, poor sperm quality, infertility, muscle loss, and fatigue will benefit the most.

The dosage of DAA-CA combined with other products doesn't do much for highly trained individuals. But if you're looking for a naturally sourced product that is easy to absorb and fight back testosterone decline, you've found it.

This t booster is suitable for vegetarians and those with digestive issues. Also, it provides the body with vital minerals and vitamins.

How To Use Testo Lab Pro for Better Results?

A serving of Testo Lab Pro contains 4 capsules. You can take two in the morning and two in the afternoon or evening.

Customer Reviews and Ratings

Side Effects of Using Testo Lab Pro

According to our research, this product has no side effects because of its all-natural and easily absorbent ingredients. Also, none of the customer reviews we read mentioned any difficulties while using the product.

As they promote on their website, Testo Lab Pro might be the world's cleanliest testosterone product because they use pure ingredients and avoid unnecessary synthetic additives.

Where to Buy Testo Lab Pro?

You can buy Testo Lab Pro only on their official website. One bottle ($69.00) contains 120 capsules, with a serving of 4 daily capsules which is enough for a month's supply.

We made the math, and this T booster costs $2.30 per serving, a bit on the expensive side. But if you buy in bulk, you can get their 4-month supply package for $207.00. It contains four bottles and free shipping. 

As said, this product is safe to use all year round, and it takes a few months to deliver all the goodies. Plus, Testo Lab Pro offers the policy of a 30-day full money-back guarantee.
