Testo Lab Pro Review 2024 | Benefits, Efficacy & WARNINGS

Want the honest truth? It may be hard for you to find the right testosterone booster on your own. If you are like the average consumer, you probably don’t know testosterone boosters in as much detail as an industry insider. It’s going to take you lots of experimenting and tons of mistakes to eventually land on the product that is best suited for you. You do not have such luxury of time and finances. 

I can help. It’s why I do these reviews. The goal is to give you the lowdown on the most prominent supplements in the market. Next up on this review series is Testo Lab Pro.

Testo Lab Pro

Overall Rating: 4.5/5

  • Increases muscle strength. Last longer in the gym and stave off the onset of fatigue.
  • Boosts stamina and restores virility and energy of youth.
  • Reduces stress. Arms you with a can-do attitude.

What is Testo Lab Pro?

Testo Lab Pro promises more power and more muscle to you by unlocking the inner natural virility and energy that characterized your youth. Boasting what it terms ‘the world’s most advanced anabolic testosterone support’, you should expect to go harder and longer both in the gym and the bedroom. And to top it all off, you get back that masculine aura of control and confidence. 

Sounds spectacular, right? To be fair, every single testosterone booster does make impressive claims. These don’t always pan out when the rubber meets the road. How does Testo Lab Pro fair? We start off by looking  at its benefits. Before I forget, Testo Lab Pro is made by Opti-Nutra, a UK-based supplement manufacturer.


Muscle Mass and Strength

There’s a natural decline in muscle mass and strength that’s just part of the aging process. But many men settle for this downward slide on the presumption that the speed of its progress is inevitable. Testo Lab Pro is formulated on the principle that this muscle and strength loss can be decelerated significantly. And it does that by stimulating protein synthesis in your skeletal muscle. 

By building and retaining your strength and muscle, Testo Lab Pro increases the length of your prime years.

Bone Density

If you are worried about strength and muscle loss as you age, you will probably be more concerned by the increased bone fragility. Bone loss and the resulting fractures curtail your movement. They increase your dependence on loved ones and carers, something every person dreads when they think about their life in advanced age.

Testo Lab Pro strengthens bone density and reduces the likelihood of fractures and dislocations when you experience those potentially debilitating slips and falls from middle age onwards.

Stress Reduction

Stress is a paralyzing, slow-acting poison that has serious short and long term effects on your overall health. A stressed man will not function as well as they could across all facets of life. They lack energy, cannot focus and do not have self-drive.

Testo Lab Pro stimulates the production of dopamine, the feel good hormone. The stress reduction is accompanied by an improvement in self confidence — that bold, masculine swagger of youth. You acquire a can-do attitude and have the resolve to tackle the everyday challenges that come your way.


D-aspartic acid (600 mg)

Abbreviated as D-AA or D-Asp, this amino acid is a ‘messenger’ that coordinates sex hormones. In men, it stimulates your endocrine system triggering a chain reaction that culminates in the production of testosterone and sperm cells. Testo Lab Pro’s D-AA is in calcium chelate form, a state that’s more easily absorbed than plain D-AA and does not irritate your stomach.

Ashwagandha (600 mg)

One of the best known gifts of Ayurvedic medicine to modern medicine and nutrition, ashwagandha is a natural testosterone booster and masculinity enhancer. Testo Lab Pro contains KSM-66, a more advanced formulation of ashwagandha. This Indian herb has been shown to lower stress, increase virility, lift confidence, enhance mental clarity, grow muscular strength and stretch physical endurance.

Mucuna Pruriens (300 mg)

Also referred to as the velvet bean, this plant enhances testosterone, libido, sperm health and semen volume. A fixture of ayurvedic, Chinese and Brazilian traditional medicine, mucuna pruriens’ main active ingredient levodopa increases dopamine levels. A by-product of this surge is improved sex drive and stronger erections.

Luteolin (60 mg)  

Luteolin is primarily found in leaves but also in tree barks and citrus fruit rinds. It slows the action of aromatase, the enzyme responsible for the conversion of testosterone into estrogen. Aromatase action accelerates with age so luteolin’s mitigating effect is especially important for men aged 40 and over.

Magnesium (50 mg)

Magnesium is classified as a macromineral given that the body needs it in relatively large quantities. It supports numerous processes in the body including boosting free testosterone levels and increasing muscle mass.

Zinc (30 mg)

Unlike magnesium, the body does not need as much zinc. That does not however diminish the critical role this mineral plays in biochemical processes. It’s included in Testo Lab Pro for its ability to regulate testosterone production, libido and vigor.

Boron (6 mg)

Testo Lab Pro’s formulation contains boron to increase testosterone and reduce estrogen.

Vitamin D (50 mcg)

Of all vitamins, none is as influential in fostering testosterone production than vitamin D.

Vitamin K (50 mcg)

Vitamin K supplementation has been shown to support testosterone production.

Pros and Cons 


  • Testo Lab Pro delivers more strength, muscle mass and bone density.
  • Improved endurance, stamina and power. You will last longer in the gym and lift progressively heavier weights.
  • Faster fat loss. Complements muscle growth resulting in a lean, chiseled physique.
  • Increased libido. Reignite the spark in your bedroom and give your relationship that vital physical bond.
  • Lifts self-confidence and focus. Get things done quickly and correctly the first time. Testo Lab Pro reduces stress as well.


  • A men-only supplement. The manufacturer actually explicitly cautions women against taking Testo Lab Pro as this could have a negative impact on their health.
  • Lower quantity of D-AA than peer testosterone boosters.

Customer reviews

So what do actual users of Testo Lab Pro have to say? Some customers highlight the reduction in body fat accompanied by increased muscle strength as well as an overall improvement in quality of life. Persons with a physically active lifestyle experience a surge of energy not just during exercise and strenuous activity but also when handling everyday tasks.

Side effects

Testo Lab Pro does not have any known side effects. If you go back to the ingredient list, you notice it's a combination of plant extracts, minerals, vitamins and amino acids - an all-natural blend. Some like ashwagandha and mucuna pruriens are backed by centuries of use in alternative medicine. 

You’d want to play it safe though. Just because a product is deemed as healthy does not guarantee it will have no adverse effect on you. Get your doctor’s clearance beforehand especially if you have previously been diagnosed with a long term health condition. And if something feels off once you start taking Testo Lab Pro, discontinue use immediately.

Frequently Asked Questions

How should I take Testo Lab Pro?

You take two pills in the morning and two in the afternoon or evening.

Testo Lab Pro contains a relatively small amount of D-AA? Should I be worried?

No. If anything, you should ordinarily be worried by ingredient quantities that exceed the average. As far as efficacy goes, some studies report a reduction in testosterone levels when D-AA supplementation is in very high doses (6,000 mg or more). Testo Lab Pro adopts a conservative approach by steering clear of the 1500 to 3000 mg D-AA quantity that many testosterone supplements settle for.

Should I take Testo Lab Pro if I’m on prescription medication?

Testo Lab Pro is safe and comprises what would be considered fairly mild ingredients. There is unlikely to be a problem taking it while using prescription medication. Nevertheless, you can never completely rule out the risk of interactions. Exercise caution — get your doctor’s clearance first.
