Testo Lab Pro is a new performance-boosting and testosterone-enhancing supplement from Opti-Nutra.

This Testo Lab Pro review covers all the essential insights you need to make an informed buying decision.

Before diving straight in, first, here’s a little bit of background info.  


Unlike other health supplements in the segment, Opti-Nutra’s Testo Lab Pro uses 100% all-natural testosterone in its formulation. You won’t see any synthetic or artificial ingredients. Instead, Opti-Nutra has relied on state-of-the-art tech and evidence-backed ingredients. This reliance is the secret behind what they call their natural three-strategy testosterone boosting.

So what’s this three-strategy found in Testo Lab Pro?

Strategy One:

Acquire optimal testosterone levels by restoring essential minerals and vitamins, such as Zinc, Magnesium, and vitamins K1, K2, and D.

Strategy Two:

Eradicate free radicals and feminizing synthetic estrogens found in plastic, food, soil, and water.

Strategy Three:

Raise testosterone levels using multiple masculinisation pathways.


Testo Lab Pro has multiple certifications, including those for being:

  • Good Manufacturing Practices
  • Vegetarian
  • Non-GMO
  • Non-irradiated

Furthermore, the health supplement is gluten-free, with no additives, caffeine, artificial preservatives or coloring.

Testo Lab Pro has also been tested and passed as containing no banned substances, an essential consideration for anyone competing professionally and athletes.

So what’s in Testo Lab Pro?

Vitamin D (via NutriGenesis – 50 micrograms 250%)

Low levels of vitamin D are typically linked to erectile dysfunction, low sperm activity, and a reduced sperm count. Higher levels of vitamin D are customarily associated with enhanced muscle strength.

Boosting vitamin D intake restores a vital sex vitamin. It has been shown to improve testosterone levels, including bioactive and free testosterone. Vitamin D also assists sex hormone binding in the blood (SHBG), which boosts bioactive testosterone availability.

Vitamin K1 & K2 (via NutriGenesis – 50mcg 42%)

Some studies are suggestive of low vitamin K levels reducing testosterone levels.

Magnesium (via NutriGenesis – 50mg 12%)

Like vitamin D, Magnesium helps SHBG in raising the availability of bioactive testosterone.

Magnesium also helps sustain free testosterone and has been demonstrated to increase overall testosterone in sedentary males and athletes.

It’s also necessary for healthy muscles and suitable for post-workout muscle recovery.

Zinc (via NutriGenesis – 30mg 272%)

A zinc deficiency can cause low testosterone, shrinking testicles, declining virility, and man-boobs. Zinc plays a vital role in boosting testosterone production and maintaining the release of testosterone.

Optimal zinc levels enhance athleticism and maintain testosterone which typically declines during exercise.

Boron (via NutriGenesis – 6mg †)

Research has shown that Boron:

  • Increases testosterone by 28%
  • Reduces estrogen by 38%
  • Blocks SHBG
  • And raises antioxidants necessary to safeguard testes against free radicals.

Boron is considered essential for muscle function and development.

KSM-66® Ashwagandha (Withania somnifera Root Extract – 600mg † 5% Withanolides)

Ayurvedic herbalism uses this root to enhance the male sex drive and virility. It has been demonstrated to increase sperm count (167%), sperm activity (57%), and semen volume by 53%.

Tests have also proven that this ingredient increases testosterone by 17% and boosts by 34% luteinizing hormone. It is also known to reduce cortisol by 57%, a hormone that kills testosterone.

Furthermore, Ashwagandha is responsible for strength and muscle size gains and improving endurance, stamina, and oxygen use. And accelerates muscle recovery while reducing soreness.

D-Aspartic Acid Calcium Chelate  (600mg †)

This ingredient is responsible for stimulating testosterone production and release. It also prompts the release of muscle developing growth hormone and the release and increased production of hormone FSH, promoting sperm formation, sperm count, and activity.

Mucuna Pruriens Seed Extract (300mg † 15% levodopa)

This seed extract, L-DOPA, converts to dopamine, which triggers

testosterone production, boosts male sex drive and virility. It also improves both sperm quality, sperm count, and the volume of semen.    

As well as stimulating growth hormone, Mucuna Pruriens has been noted in combating the feminizing impact of xenobiotics. And credited with boosting antioxidants to protect the testes and adaptogen herbs to reduce cortisol.

Orange Extract (Luteolin – 60mg †)

This fruit extract blocks testosterone converting to estrogen, strongly overpowers xenobiotics and protects against free radicals.

The Daily Values are based on a 2,000 calories per day diet.

† Daily Value not established.

How To Take Testo Lab Pro

The recommended dosage is four capsules daily, preferably two in the morning and two later in the day. For best results, you should take Testo Lab Pro regularly in conjunction with exercise. This combination will naturally up testosterone more than the supplement alone.

Why Do We Need Testosterone?

Testosterone is the male sex hormone and plays a key role in regulating libido, bone and muscle mass, strength, fat distribution, and the production of sperm and red blood cells.

What Are the Symptoms of Low Testosterone?

Testosterone levels drop slowly and progressively from the age of 30. Symptoms of low testosterone are therefore subtle. The rate of the decline in testosterone depends on several variables, including genetics, fitness levels, body composition, etc.

However, several diseases and conditions can suppress testosterone production. These include tuberculosis, histiocytosis, sarcoidosis, HIV/AIDS, pituitary disorders, Kallmann’s Syndrome, radiation therapy, surgery, some medications, and obesity.

More apparent signs of low testosterone include the loss of body and facial hair, fatigue, lower energy levels, decreased muscle mass, low sex drive and erectile problems, irritability, and depression. 

Are Testosterone Supplements Necessary?

There is no definitive answer. However, there are indications backed by science that indicate a 22% decrease in men’s testosterone levels in the past two decades. It’s now thought declining testosterone can affect men as young as 22.

Researchers have shown that potentially one in every four men has a testosterone deficit.

If in doubt, always consult your doctor, as a blood test will determine if your testosterone level is low.

Will I Notice a Difference?

As a sports nutrition expert and personal trainer, I took Testo Lab Pro for two months as an experiment. I can’t say I noticed anything different.

I am committed to training and eating healthily, but since hitting 30, the last few years have been a battle. My muscle mass and strength have declined, but I feel I have been going backward despite my best efforts.

There is also a male family history of CMT (Charcot-Marie-Tooth) disease. One of its primary symptoms is muscle loss and weakness. While I am not medically-qualified to dispense health advice, I am very aware of the need to prevent muscle loss or, at least, slow it.

However, should a testosterone-supplement help push up my testosterone and help me stay strong, then I’m willing to investigate the potential long-term benefits.

* Note: As well as Testo Lab Pro, I was simultaneously taking Performance Lab’s multivitamins and minerals and their SPORT protein.

Final Verdict: Is Testo Pro Lab a Good Buy?

Health supplements cannot be regarded as substitutes for a healthy diet and lifestyle. However, they are great nutritional insurance and convenient if you believe diet and exercise alone are not providing everything you need.

There are numerous ways to naturally raise your testosterone levels, such as:

  • Rest and good quality sleep
  • A healthy, well-balanced diet
  • Incorporating strength training into your workouts
  • Multivitamin and mineral supplements
  • Minimising stress to reduce cortisol levels
  • And avoid estrogen-acting compounds.

If, though, you feel your testosterone is low despite your actions or the result of aging, you may wish to consider a testosterone-boost supplement.

As a result of my personal research on testosterone-boosting health supplements and the various options currently available, I have no hesitation in recommending Testo Lab Pro. They produce one of the best products on the market today. 

They adopt a cutting-edge, no-hype approach in using only natural ingredients in potent volumes. There are no synthetic ‘fillers’ you often find in cheaper and inferior products. This is what distinguishes Testo Pro Lab from the rest.

Give It a Go

If you are planning to supplement with a T-booster, I would personally recommend Testo Pro Lab.

Why not give it a go if your muscle mass and strength are in a slow, steady, and worrying decline? 

Especially, if like me, as you age, you find diminishing returns by merely eating well, working out, getting good quality sleep, and limiting stress. 

There is no financial risk involved with Testo Pro Lab. Such is their confidence and commitment that they back their product with a 30-day money back guarantee. If you cannot see any results or are not 100% satisfied, you get your money refunded.
