Testo Lab Pro Review: Should You Buy it? (UPDATED)

Testo Lab Pro Review: In this review, we’ll be taking a look at an exciting new male health supplement from Opti Nutra. Even though it’s a relatively new testosterone booster, Testo Lab Pro is already making waves due to its impressive quality and research-backed ingredients.

If the claims on the manufacturer’s website are accurate, Testo Lab Pro will help you:

  • Get stronger in the gym– train harder for longer, improve your PRs by 1-2 reps.
  • Feel better mentally – reduce the effects of the stress hormone cortisol on the body and mind.
  • Better Recovery – experience less soreness, recover faster from gym sessions.
  • Safe & legal test boost – provides nutrients and raw T materials for naturally enhanced production of the hormone in the testes, along with reducing estrogen, cortisol and other testosterone diminishers.
  • Improved sex life – More confidence, stronger erections, higher levels of libido.

Opti Nutra, the makers of Testo Lab Pro, are known for their extremely strict and high-standard manufacturing. Their products are third-party tested, cGMP and FDA manufactured, and free of pointless ingredients. Testo Lab Pro uses plant-based prebiotic NutriCaps® to make other ingredients highly absorbable and easy on your digestion.

So, is Testo Lab Pro worth the money? It’s got amazing reviews already, but how much truth is there behind the claims. In this Testo Lab Pro review, we look closer at the supplement and give you our thoughts.

Testo Lab Pro Review – How Does it Work?

  1. Increases the levels of both free and total testosterone – by stimulating Leydig cells in your testes.
  2. Optimizes DHT and other androgen hormones – by restoring missing vitamins & minerals required for their synthesis.
  3. Makes more space for testosterone to grow – by blocking cortisol, estrogen, prolactin, and SHBG.
  4. Enhances mental fortitude – by optimizing neurotransmitters that regulate mood & focus.
  5. Stimulates the natural release of Human Growth Hormone (HGH) – resulting in increased muscle growth and faster recovery.

Below, you’ll find more about the ingredients in Testo Lab Pro, as well as the relevant studies that support its benefits.

Who Makes Testo Lab Pro? About Opti Nutra

Opti Nutra is a UK-based specialist company that owns several well-known products in the supplement market. Their most popular formula is Mind Lab Pro, which currently sits as the #1 reviewed nootropic on most critique sites.

Opti Nutra has been around since 2015. Their team consists of fitness experts and PhD scientists. We did a little digging and found they do things a little differently from other companies. These include:

  • They only sell directly – You can only get Testo Lab Pro from the manufacturer’s website
  • International friendly – Opti Nutra ships worldwide and fast from their warehouses in the USA and UK.
  • Quality is their biggest selling point – You won’t find any fillers, artificial ingredients, or chemicals in Opti Nutra’s products. They use standardized, patented forms of ingredients to ensure maximum safety, cleanliness, and results. They even grow their own nature-identical nutrients on probiotic bacteria and yeast in strict lab conditions.
  • They are 100% confident in what they sell – You’re covered with a 30-day money back guarantee if you don’t like their products.

The main reason we like Opti Nutra is that they’ve chosen to sell their supplements for themselves rather than being pushed by bigger companies like GNC or Amazon. This way, they can keep ensuring high quality without having to raise their prices to cut in the middle man.

How it Worked for Us

Testo Lab Pro is the latest blockbuster in the testosterone booster market. You’ll see all kinds of products and blends all over the internet saying they’re “scientifically proven,” but in reality, these studies are thin and typically done on rats. Testo Lab Pro’s ingredients are based on robust human evidence, which made us curious to try it out for ourselves.

Our 3-month order from Testo Lab Pro was pricey, but it was delivered fast and with free shipping. It was actually a much better deal than choosing a 1-month package because we got 1 extra Testo Lab Pro bottle for free, and the total cost was $1.73 per serving.

1 week on Testo Lab Pro led to an increased feeling of energy and we slept a lot better. Gabriel, one of our editors, was frustrated remembering to take 4 capsules daily at first, but quickly got into the swing of it.

By 2nd week we felt like we’d been missing out by taking so many ineffective testosterone boosters. Our workouts were better, bedroom performance improved a lot too. To be honest, we were horny as hell!

By the time we finished the first bottle, we’d seen good muscle gains and unexpectedly, some belly fat loss. Our recovery and inflammation has also improved immeasurably, which is likely attributable to reduced stress hormones and increased testosterone.

To summarize our results after 3 months of using Testo Lab Pro:

  • Ivan’s test levels went from 14.5 nmol/l to 20.3 nmol/L after supplementation
  • More muscle mass and better physical performance (1RM went up in squats and deadlifts)
  • Increased sense of confidence and masculinity
  • Best sleep ever, less Delayed-Onset Muscle Soreness
  • Older editors said they felt younger again

I’d definitely recommend this test booster for any guy, young or old, who wants to boost T and feel better mentally.

The results from using Testo Lab Pro look promising, but what does the science for the ingredients have to say.

We’ve looked deeper into the formula of Testo Lab Pro to see how effective it really is, just so we know we weren’t fooled by the ‘placebo effect’.

Testo Lab Pro supplies you with the following ingredients:

  • NutriGenesis®  Zinc (30mg)
  • NutriGenesis® Magnesium (50mg)
  • NutriGenesis® Boron (6mg)
  • NutriGenesis® Vitamin D3 (2,000IU)
  • NutriGenesis® Vitamins K1 and K2 (50mcg)
  • KSM-66® Ashwagandha (600mg)
  • Mucuna Pruriens Extract (15% Levodopa) (300mg)
  • D-Aspartic Acid Calcium Chelate (600mg)
  • Luteolin (from orange) (60mg)

Right off the bat we can tell you what we like about this supplement and what they improve:

  • Vitamin D3 – Improves testosterone, strengthens bones, supports a bright mood.
  • Zinc – Prevents dips in testosterone from stress and hard exercise.
  • Magnesium – Elevates free testosterone levels.
  • D-Aspartic Acid – One of the most potent natural T boosters around.
  • Ashwagandha, Luteolin, Mucuna Pruriens – Improve mood, block the conversion of test to estrogen, and promote hormonal balance.

What’s more, Testo Lab Pro’s formula is free of proprietary blends. Supplement makers often use these blends to hide individual ingredient doses on the label, only showing you their combined amounts. This makes it very hard if not impossible to tell if a product is safe and if it works.

Apart from being 100% transparent, you’ll notice Testo Lab Pro first restores key vitamins and minerals for high T that many men are deficient in. This serves as a strong foundation for the rest of the formula to build upon.

The nutrients in Testo Lab Pro are clean cultured, nature-identical grown in Opti Nutra’s laboratory using NutriGenesis®. Plus, it’s all packed in eco-friendly, BPA-free recyclable boxes.

In the next section of our Testo Lab Pro review, we’ll check the ingredients to see how exactly they work in your body and what the science has to say about them.

NutriGenesis®  Zinc (30mg)

Commonly found in foods like oysters, clams and spinach, zinc is a great mineral in Testo Lab Pro. When supplemented it can do wonders for your male hormone.

After ingestion, zinc can be used for different chemical reactions in your brain to help make the Luteinizing Hormone (LH). LH is crucial to the process, your body uses it as a building block for both growth hormone and testosterone.

The more support your Luteinizing hormone has to grow, the more potential your body has to make HGH and T.

Studies show that zinc supplementation during 6 weeks has a significant impact on raising testosterone. Not only that, a study found that zinc can prevent drops in testosterone that are caused by stressors like hard exercise.

NutriGenesis® Magnesium (50mg)

Magnesium is another crucial mineral for testosterone. Commonly found in foods like kale, it’s great for helping your free testosterone particularly.

By free testosterone, I mean the testosterone that is available for your body to use. It’s circulating in your blood ready to be taken up by tissues. However, you also have in your blood a protein called Sex Hormone Binding Globulin (SHBG) which binds to most of your free testosterone and renders it inert.

After testosterone is bound to SHBG, it becomes unusable, without any anabolic effect. Magnesium steps in here to release your testosterone from the ‘shackles’ of SHBG by binding to SHBG itself. The result? You have more free testosterone circulating in your blood.

Just like with all other vitamins and minerals in its formula, Testo Lab Pro uses NutriGenesis® magnesium which your body recognizes as nature-identical – resulting in easy absorption and utilization.

NutriGenesis® Boron (6mg)

This is another trace mineral, a chemical found in foods such as prunes, apriconts and brazil nuts. Boron helps shuttle other minerals such as calcium where they’re needed in your body. As a result, it can reduce symptoms of bone loss, arthritis, and even help regulate cell membrane health.

As far as testosterone goes, boron seems to be extremely effective at raising it. Although we still need more studies to see just how much boron can raise testosterone, the current evidence suggests that even short-term supplementation can increase free testosterone by 14.7%, boost DHT by 10%, and reduce testosterone’s arch-enemy SHBG by 9%.

A longer study found that only 2.5mg of boron was enough to boost androgen levels in elite bodybuilders by 62% over 9 weeks!

NutriGenesis® Vitamin D3 (2,000IU)

In our eyes, this is the best natural testosterone booster in general. Vitamin D3 is so potent it’s technically a seco-steroid hormone, and acts as a precursor to raising your testosterone levels.

Not only that, D3 is found in every cell of your body which means it can regulate everything from your bone density, mood, immune system, and muscle hypertrophy (growth).

Do you want to know the issue, though? An estimated 1 billion people worldwide don’t get optimal levels of this crucial hormone. This is because your body mainly absorbs it through direct sun rays with the help of cholesterol. And most people don’t get enough bright, hot sun to synthesize optimal levels of this anabolic vitamin.

Supplementing 2,000IU of nature-identical vitamin D in Testo Lab Pro is a safe and healthy way to support your testosterone production long-term.

NutriGenesis® Vitamins K1 and K2 (50mcg)

Vitamins K1 and K2 both play an important role in regulating mood, cardiovascular function, and yes, testosterone production too. Although they’re more of a ‘silent heroes’ in Testo Lab Pro.

Vitamin K1 is abundant in green leafy vegetables. And so it’s not that hard to obtain from our diet. But vitamin k2 is found in egg yolks, liver, butter and other foods high in fat. These may not be in line with your health and fitness goals. The best solution, therefore, is to supplement vitamin K2 instead, in its cleanest and most bioavailable form, which is exactly what Testo Lab Pro has.

According to numerous studies, vitamin K complements vitamin D3 in boosting testosterone, bone health and more. Not only do K vitamins play a supportive role in ramping up your anabolic hormones, they do it directly too. One clinical trial found that supplementing vitamin K2 for just over a month led to a stunning 70% increase in circulating testosterone.

KSM-66® Ashwagandha (600mg)

Ashwagandha is a root herb from Ayurveda medicine. It was traditionally used for physical and mental vitality enhancement. Its active withanolides help boost your testosterone by:

  1. Optimizing Hypothalamic-Pituitary-Adrenal (HPA) axis and regulating cortisol, a stress hormone that can diminish T levels.
  2. Supplying targeted antioxidant protection from free radicals that damage testicular cells, sperm, and testosterone

Testo Lab Pro features KSM-66®, which is the strongest full-spectrum ashwagandha extract with 5% active withanolides. It’s also the only 100% Organic Patented ashwagandha.

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

Mucuna Pruriens, or Velvet Bean, is a male tonic plant that contains levodopa (L-DOPA). L-DOPA is an effective active compund for mental well-being and masculine health, it works by:

  1. Stimulating the brain to spurt gonadotropin-releasing hormone (GnRH)
  2. Signaling to the pituitary gland to make luteinizing hormone (LH)
  3. Promoting increased T synthesis in the testes in the presence of LH
  4. Increasing dopamine brain levels for elevated motivation & focus

Sounds impressive, right? However, Mucuna also acts as an inhibitor of the T-reducing hormone prolacting while also boosting human growth hormone. And according to studies, Mucuna is even more potent at increasing T in men with low sperm count or infertility.

Testo Lab Pro’s Mucuna Pruriens is strong. 4.2% levodopa is what’s typically found in Velvet beands. Testo Lab Pro supplies you with 15% levodopa. Therefore, one serving of Testo Lab Pro supplies levodopa equivalent to 8.6g of Mucuna pruriens!

D-Aspartic Acid Calcium Chelate (600mg)

DAA-CC is an amino acid with a strong positive effect on your endocrine system. It enhances sex hormone balance and testosterone production by:

  1. Stimulating the hypothalamus to release GnRH, which in turn raises Folicle Stimulating Hormone (FHS) and Luteinizing Hormone (LH)
  2. Stimulating the pituitary gland to spurt growth hormone and luteinizing hormone (LH); which then signals to testes to increase the production of sperm and testosterone

Testo Lab Pro’s D-Aspartic Acid is bound to calcium chelate molecules (the “CC” part) to improve absorption and digestability. You may be curious, since many other testosterone boosters use 3,000mg of more of DAA per serving, why does Testo Lab Pro only have 600mg?

The answer lies in how DAA works. You see, DAA has been shown, at higher doses, to significantly elevate testosterone but only for the short term. After a while, your testosterone goes back to baseline. As a result, higher DAA doses need to be cycled to keep the benefits coming.

On the other hand, Testo Lab Pro uses a safe maintenance dose of 600mg of DAA-CC, which maintains its effects without the need for cycling. The increase in testosterone is not as sharp as with higher DAA doses, but it lasts longer.

Luteolin (from orange) (60mg)

Luteolin is a plant antioxidant that boosts your testosterone levels indirectly, by blocking the enzyme aromatase. Aromatase turns your testosterone into the female sex hormone estrogen.

Luteoline’s bioactivity is helpful for:

  1. Stacking with D-Aspartic Acid Calcium Chelate: Luteolin boosts DAA-CC’s anabolic boosting activity to work to the maximum effect.
  2. Men over 30: Luteolin contributes to youthful estrogen-to-testosterone ratio, which slowly goes out of whack as men grow older and start experiencing symptoms like man boobs, prostate growth, and belly fat accumulation.

How to Use Testo Lab Pro

Testo Lab Pro dosage is 4 NutriCaps® daily. You should split these into at least 2 servings per day by taking 2 capsules in the morning and 2 in the afternoon/evening.

For even better results, you should aim to take 1 capsule 4 times per day. This will keep your body fueled with beneficial nutrients all day long. Annoying to remember? Yes. Does it work? Try it for yourself and see the difference!

Side Effects

We haven’t heart reports of side effects from people taking Testo Lab Pro. No one from our team had any issues with it either. The ingredients themselves are safe and well-studied, and the doses aren’t aggressive like with some test boosters.

Still, we do recommend talking to a qualified MD to help you decide whether you should take this product or not. Especially if you have any kind of condition. Remember that our posts are for entertainment and informational purposes only; they aren’t meant as advice!

Do You Need to Cycle Testo Lab Pro?

No. Testo Lab Pro doesn’t need to be cycled. As we said, the ingredients come in clinically researched doses. Even DAA comes at 600mg, making it healthy for daily use.

Don’t be fooled by marketing. Often, supplement companies will tell you to cycle their testosterone booster, implying that it somehow works similar to steroids. This obviously is not true – no natural T booster even comes close to these aggressive illicit substances!

Price and Value for Money?

Testo Lab Pro comes with excellent discounts on bulk purchases.

Buying 1 month supply (1 box) will cost you $69, but buying a 3-month supply will get you one extra bottle for free with free worldwide shipping, for the price of $207.

Breaking it down, the 3-month supply will cost you $1.73 per serving. Less than a cup of coffee but with better effects. And if you aren’t happy with Testo Lab Pro you’re covered by a hassle-free 30 day guarantee. Returning the product will get you a refund from their team quickly and easily.
