All about Testosterone Boosters

To start off, it is important to have an idea about what testosterone boosting supplements actually are.

What is Testosterone?

A very basic, but necessary FAQ to get out of the way- what is testosterone? Typically considered a male or ‘androgen’ hormone, it is also present in women, albeit at significantly lower levels.

Testosterone is the hormone that gives men the typically ‘male’ attributes, whether it be the deeper voice and facial hair, musculature, strength and endurance, or libido and the growth of the reproductive organs.

Why are Fitness Enthusiasts Concerned about Testosterone Levels?

Remember when I mentioned testosterone levels govern the quality of your musculature, strength, and endurance? That is exactly where your testosterone levels come into play if you are a fitness enthusiast or athlete, particularly if you are training for mass gain.

To bulk up efficiently and increase your muscle mass beyond a point, you need your testosterone levels to be boosted. To sustain working out as vigorously as you need to, your body needs to keep up.

Boosting your testosterone would also enhance your strength and endurance, and how well you respond to the taxing and regular strength training you must be subjecting your body to.

What are Testosterone Boosting Supplements?

Testosterone boosting supplements, as the name suggests, are supplements that help boost your body’s testosterone levels. It is important to remember, these testosterone boosters are not the same as injectable or transdermal testosterone boosters involved in testosterone replacement therapy (TRT) which is a medical and pretty hardcore treatment that replaces your body’s natural testosterone.

Testosterone boosting supplements simply boost the levels of the testosterone that your body already produces. They are much more conducive for regular consumption, with negligible side effects, and show consistent results.

Apart from enhancing your athletic performance and performance at the gym, testosterone boosters also improve your sex drive and sexual performance and also serve as a great mood and energy booster.

What is Testo Lab Pro?

Testo Lab Pro is the new testosterone booster launched by Opti Nutra, a UK-based supplement company. This genius formula contains a well-researched blend of 6 testosterone boosters and performance enhancers along with Opti Nutra’s patented nature-identical nutrients for testosterone enhancement created using their unique NutriGenesis® nutritional technology.

About the Makers: Performance Lab

Opti Nutra is definitely not a new name in the world of nutritional supplements, and has been in our radar for a while now. This UK-based supplement brand has cemented its position as one of the most trusted and go-to brands for fitness enthusiasts and athletes thanks to their stringent attention to quality and manufacturing standards.

Furthermore, all their supplements are devoid of any additional unnecessary filler ingredients, are third-party tested, and are ratified by cGMP and FDA. You might have heard of Opti Nutra before in connection to their leading supplement, Mind Lab Pro, which also happens to be the world’s most trusted and bestselling nootropic supplement. 

The landslide success of their Mind Lab Pro was followed by a number of other well-received premium nutritional supplements, and Opti Nutra has pretty much become synonymous with state-of-the-art innovations in the world of supplements aimed at high performers.

In keeping with Opti Nutra’s uncompromising attention to the quality of their products, the brand only sells from its own website, nixing the possibility of any tampering by a third-party seller. 

Opti Nutra’s prioritization of the consumer experience and premium quality products has ensured that pretty much every product from the brand has been ranking in the relevant charts.

Who is Testo Lab Pro For?

TestoLab Pro booster

Testo Lab Pro, since it is a testosterone booster, caters specifically towards men. Men across ages may consider this product as a safe way to naturally enhance your testosterone levels.

If you are looking to increase your muscle mass, athletic performance and recovery, mental fortitude, virility, and libido, Testo Lab pro is the perfect supplement for you to place your bets on.

It has also proven to benefit professional athletes in their performance, as well as men over 30 who may be experiencing a disbalance of androgens to female hormones.

Testo Lab Pro Review

TestoLab Pro Benefits

The impressive claims about the performance of Testo Lab Pro, and the raving consumer reviews backing them, definitely makes Testo Lab Pro a supplement to consider investing in.

Let’s have a look at what the brand promises about Testo Lab Pro, and whether it ticks the right boxes:

● Stronger Lifts

One of the main benefits of any testosterone booster is that it enhances your performance in the gym. Strength training typically benefits the most from a T-booster. Testo Lab Pro definitely delivers on this front by ensuring you can train intensely and for longer periods, without your body giving up.

● Enhanced Recovery

For successful muscle gain, how well you recover is just as important (if not more) as to how much you work out. When you work out harder and push your limits, your muscles suffer some wear and tear.

As they repair themselves, the muscles grow and expand. Testo Lab Pro improves this recovery process, thus contributing to more effective mass gain without suffering a physical burnout. The T-booster reduces the soreness of your muscles after an intense workout, so you can get back to your weights pronto and further push your limits further.

● Fat Loss

An interesting benefit of Testo Lab Pro is that while enhancing mass gain, it also encourages fat loss. The resultant effect is that of solid musculature and brawn, with no flab.

● Mental Health

While the effect of stress on your body is quite evident, stemming from a fast paced modern lifestyle as well as your intense fitness regime, mental stress can be a silent killer.

We often don’t consciously register or pay heed to the effect of stress on our minds, but it can be the root of a major burnout and breakdown. Testo Lab Pro addresses this issue by not only alleviating physical stress, but also alleviating the stress on your mind.

● Safe Testosterone Boost

Testosterone boosters can sometimes end up toeing the line of safety and legality, due to the testing procedure. Testo Lab Pro is completely safe and legal in its stimulation of the testosterone production in the testes. Additionally, it also suppresses the levels of estrogen, cortisol, and other known T-killers.

● Better Sex Life

A natural effect of any testosterone booster is the boost in libido and sexual performance. Testo Lab Pro effectively gives your sex life and self-esteem a boost, and makes you much more confident in the sack.


  • The packaging of Testo lab pro is very eco-friendly. The bottles are 100% recyclable and BPA-free
  • The ingredients are completely safe and backed by extensive research and testing
  • The recommended 4 servings a day ensures you get the benefits through the entire day, and you can split the number of capsules you are taking at a time based on your convenience
  • It boosts anabolic hormones leading to mass gain, aids in fat loss, reduces stress, and enhances your libido and virility
  • Opti Nutra is a very well reputed brand that is trusted by consumers across the world


  • You cannot consume Testo Lab Pro on an empty stomach. You have to coordinate it with your meal times
  • It is a tad expensive, but there is a price to pay for premium ingredients, manufacturing and brand value
  • The supplement is only available on Testo Lab Pro’s website, though the excellent customer service and worldwide shipping don’t make it too much of an issue

Testo Lab Pro Ingredients

Testo Lab Pro contains a potent blend of ingredients that work superbly well in tandem with each other to bulk you up effectively, but there is no unnecessary bulking of the ingredient list.  When you are settling for a nutritional supplement meant for daily consumption, the simpler the formulation, the better- too many cooks, as they say, spoil the broth.

The formulation of Testo Lab Pro comes encased in Opti Nutra’s trademark NutriCaps®. These are premium quality plant-based capsules that are infused with prebiotics and get easily digested, and consequently absorbed, into your body.

You would also see a lot of NutriGenesis® nutrients in the blend. This patented technology of Opti Nutra creates nature-identical vitamins and minerals right in the lab that are clean-cultured and highly absorbable.

Any Appealing Features?

One of the most appealing features of the Testo Lab Pro ingredient list is that it does not contain any proprietary blends, which ensures that formulation maintains 100% transparency to us consumers. A lot of popular nutritional supplements often resort to proprietary blends and therefore do not show the exact composition of the product- they show the combined amount instead, which may be an issue when determining how safe the product as well as its efficacy.

Testo Lab Pro meticulously lists out every ingredient and their exact dosage on the label, so you can check for yourself its stellar efficacy and whether you find a particular ingredient to be unsuitable for you.

To break down the formulation of Testo Lab Pro at a very empirical level- the product has a solid foundation of nutrients (yes, their classic NutriGenesis® ones) to replenish certain key ones that men often fall short on, along with t-boosters and performance enhancers, for optimum results.

Let us now delve deeper into the ingredient list and go over each constituent’s specific benefits to complete our Testo Lab Pro Review.

1. NutriGenesis® Magnesium (50 mg)

The primary function of magnesium in the formula of Testo Lab Pro is boosting the ‘free testosterone’ levels and total testosterone levels, thus enhancing the levels of human growth hormone (HGH) and muscle mass.

‘Free testosterone’ is essentially the testosterone circulating in your blood and available for use. It is in a conducive state for your tissues to absorb. The problem arises because of the presence of Sex Hormone Binding Globuline (SHBG) in your blood as well. SHBG is a protein that binds, and renders inert, your free testosterones.

When bound to SHBG, the testosterone cannot be absorbed by the tissues without an anabolic effect.

Here is where magnesium comes into play. Magnesium exchanges its position with the testosterone that is bound to SHBG. While it itself binds to SHBG, the testosterone is free once again and can circulate in your blood to be absorbed by the tissues when needed.

Typically, magnesium can be found in foods such as kale, spinach, pumpkin seeds, almonds, quinoa, etc. Testo Lab Pro contains NutriGenesis® magnesium which is nature-identical, and can therefore be absorbed efficiently and quickly by your body and properly utilized.

2. NutriGenesis® Zinc (30 mg)

In a nutshell, Zinc is a nutrient that boosts testosterone production in the body and optimizes its release, therefore improving your libido and virility.

Lutenizing hormone, or LH, is an important hormone which is utilized by the body in the creation of growth hormone (HGH) as well as testosterone. When you consume zinc, it aids in the chemical reactions taking place in the brain to secrete more LH.

Typically, zinc is found in food items such as spinach, beans, crabs, lobsters, oysters, etc. and Testo Lab Pro’s NutriGenesis® Zinc emulates this powerhouse nutrient.

3. NutriGenesis® Boron (6 mg)

The function of boron in Testo Lab pro is to increase the predominance of the male hormones, by increasing T-levels while suppressing estrogen and SHBG.

According to research, consistent boron supplementation (even if it’s over a short period of time) contributes to increasing testosterone by 14.7% and dihydrotestosterone (DTH) by 10%, while reducing SHBG levels by 9%. Thus, boron makes your male hormone levels soar.

According to a study on elite bodybuilders, a daily dosage of just 2.5 mg boron over 9 weeks caused their androgen (male hormones, including testosterone) levels to climb by 62%.

Boron also works wonders to maintain the health of cell membranes, and to counter bone loss or arthritis.

Boron is a trace mineral that is found naturally in foods such as apples, apricots, coffee, dried beans, prunes, potatoes, brazil nuts, etc. Testo Lab Pro contains nature-identical NutriGenesis® Boron which enhances the formulation.

4. NutriGenesis® Vitamin D3 (2,000 IU)

Improving total testosterone levels and the levels of bioactive and free testosterone, Vitamin D3 is possibly one of the best natural T boosters out there.

As you can tell, vitamin D3 is a pretty important anabolic vitamin. However, over a billion people across the world fall short of this nutrient. The reason? Unfortunately, vitamin D3 is not naturally synthesized in the body. It can only be absorbed through exposure to direct sun rays with the help of the cholesterol in your body.

Testo Lab Pro offers the perfect solution by recreating the potency of naturally occurring Vitamin D3 in the lab using NutriGenesis®, and therefore amping up the potency of the formulation considerably.

5. NutriGenesis® Vitamins K1 and K2 (50 mcg)

Vitamin K, in this case K1 and K2, are great for raising testosterone production levels as well as regulating cardiovascular functioning and your mood. It is one of those ingredients that don’t usually get much hype, but actually contribute towards amping up the formulation of Testo Lab pro considerably.

Vitamin K complements vitamin D3 and increases its efficacy in maintaining bone health and increasing T levels. Along with supporting other anabolic hormones, they themselves contribute towards the same directly as well. In fact, according to research, vitamin K2 supplementation for around a month can contribute towards a 70% boost of circulating testosterone. Pretty amazing, isn’t it?

While vitamin K1 is quite easily available in food sources such as leafy greens such as kale and spinach as well as other green vegetables such as broccoli, cabbage and Brussels sprouts, vitamin K2 sources such as butter, egg yolks, and liver, often fall under various dietary restrictions.

Adding NutriGenesis® vitamins K1 and K2 into the Testo Lab Pro formula was definitely a genius move by Opti Nutra.

6. KSM-66® Ashwagandha (600 mg)

Ashwagandha is an adaptogenic root herb popular in Ayurvedic medicine which is used commonly for the enhancement of physical and mental vitality.

This indigenous ingredient contains withanolides which help boost testosterone by regulating cortisol (a stress hormone that can be a testosterone killer), optimizing the Hypothalamic-Pituitary-Adrenal (HPA) axis, and supplying antioxidant protection against free radicals to testicular cells, sperms, and testosterone.

KSM-66® is the strongest full-spectrum Ashwagandha extract and it contains 5% active withanolides. KSM-66® is also the only Ashwagandha extract that is patented. Testo Lab Pro incorporates this variant into the ingredient list, thus enhancing muscle size and strength, mental fortitude, and virility.

7. Mucuna Pruriens Extract (15% Levodopa) (300 mg)

Mucuna Pruriens, commonly known as Velvet Bean, is another herb which serves as a male tonic. It contains Levodopa (L-DOPA) which is a compound that enhances masculine health (sexual health and performance) as well as mental health.

While the naturally occurring concentration of L-DOPA in Velvet Bean is approximately 4.2%, Testo Lab has a potent concentration of 15% Levodopa which is equivalent to that in 8.6 gm of Mucuna Pruriens.

8. D-Aspartic Acid Calcium Chelate (600 mg)

D-Aspartic Acid Calcium Chelate, or DAA-CC, is an amino acid which boosts the functioning of the endocrine system, and thus improving the sex hormone balance and testosterone production.

DAA-CC encourages the hypothalamus in your brain to increase the production of GnRH, therefore contributing to the increase of Follicle Stimulating Hormone (FSH) and LH levels. It also stimulates the pituitary gland to increase the production of HGH and LH, thus enhancing the production of sperm and testosterone in the testes.

The calcium chelate (CC) bond of the DAA present in Testo Lab Pro improves the absorption and digestibility of the ingredient. The 600 mg dose present in Testo Lab pro is a safe and moderate amount which ensures that there is a consistent cycling of the DAA-CC in the blood consistently boosting testosterone, instead of spiking it for a short while and dropping again.

9. Luteolin (60 mg)

Luteolin is an antioxidant sourced from plants (oranges, in the case of Testo Lab Pro), which indirectly boosts testosterone levels by suppressing the enzyme aromatase which converts testosterone into estrogen (the female sex hormone).

It is a bioactive ingredient which pairs well with DAA-CC by boosting its anabolic function. It is also great for men aged over 30, by ensuring they maintain the testosterone-estrogen ratio of a man at his prime.

This is essentially, because as you might have noticed, men often develop man boobs, and belly fat accumulation due to the increase of estrogen levels as they grow older. The luteolin in Testo Lab Pro nixes this.

How to Use Testo Lab Pro

The recommended dosage of Testo Lab Pro, according to Opti Nutra, is 4 capsules daily. Splitting the dosage through the day ensures optimum cycling of the nutrients in the body throughout the day.

You could consume 2 capsules in the morning and 2 in the evening, or consume 1 capsule four times a day to spread it out further. Of course, you cannot see results overnight. The supplement should be consumed consistently over a period of time to see best results, just like any other nutritional supplement.

Stackability of Testo Lab Pro 

The transparency of the ingredient list and simple composition ensures that you can stack Testo Lab Pro with any other nutritional supplements that you may be taking.

Though it is very unlikely, to be on the safe side, double check the ingredients of the other supplements you intend on taking to make sure you don’t end up suppressing any of the benefits.

Testo Lab Pro Side Effects

TestoLab Pro side effects

As I mentioned, the ingredient list of Testo Lab Pro is very minimal and fuss-free. Every ingredient is well-researched and the dosages are optimized and moderated to make sure you get the safest formulation possible.

Though a relatively new kid on the block, Testo Lab Pro has definitely flown off the racks and has a wide consumer base- yet there have been no reports of adverse reactions that I came across while looking up the product.

Nobody in the team who tried out this product had anything but good things to say about it, and there were no side effects to complain about. However, like all other supplements, it is best to consult your doctor before committing to the product- especially if you have any medical conditions.

Clean Formulation

Testo Lab Pro not only has a uniquely safe formulation due to the stringent quality checks during manufacture and a cGMP and FDA approved ingredient list, but it is also a very versatile product that can fit into your routine regardless of your dietary restrictions.

The product is non-GMO and non-irradiated, contains no synthetic additives, artificial colours, preservatives, or any banned substances. It does not contain most known allergens such as gluten, wheat, soy, egg, fish, dairy, tree nuts, peanuts, shellfish, etc. It also does not contain caffeine.

Often, manufacturers hide sketchy ingredients under the ‘other ingredients’ tag listed in the ingredients. Testo Lab Pro scores brownie points by not only disclosing what these ‘other ingredients’ are, but the only ingredients you would find listed here are NuFlow® (a very safe rice concentrate which helps make the manufacturing process efficient by serving as a natural flow agent), and Opti Nutra’s patented NutriCaps® capsule encasing.

Pricing and Cost Efficacy

Testo Lab Pro is an excellent product to bet your money on, literally, because of the great discounts the website offers on bulk orders. While a single box (a month’s supply) is priced at $69, you can get an excellent discounted price of $207 along with an extra free bottle and free worldwide shipping if you purchase 3 months’ supply at a go.

This is a brilliant deal, as it would imply a single serving of Testo Lab Pro would cost you $1.73- definitely a better investment than the overpriced sugar-laden coffee you can get at the same price!

Furthermore, Opti Nutra has excellent customer service, and you can get a complete refund without any fuss if you are not satisfied with the product, thanks to their 30 day money back guarantee.

Final Thoughts: Does TestoLab Pro Match Up to the Tall Claims?

According to our Testo Lab Pro Review, the product definitely delivers on its promises, and more. Everyone who tried the product in our team had nothing but raving reviews, even within the first month of using it.

Spiked energy and better sleep was the common consensus when reporting on the first week or so of using the product. The workouts were reportedly better, and the recovery was astonishingly fast.

The team also confessed that their performance in the sack was definitely enhanced. Within the first month of usage, we could corroborate all of Testo Lab Pro’s claims, whether it be muscle mass gain, endurance, belly fat loss, libido and virility, or mental clarity.
