Pre Lab Pro Review

Are you rarely motivated to get a good workout in? Do you feel like you could be getting more out of your activities when you do exercise? Have you been unimpressed with the wide range of pre-workouts available today? Do you need more than caffeine in your system to work out?

If you answered yes to any of the above questions, you have come to the right place. Most pre-workouts today feature similar formulas, and while most of them boost your energy levels, they do so with large amounts of caffeine and not enough of everything else the body needs. 

That is because most pre-workouts available today are not formulated with the right intentions. The ones that do not work are simply trying to force some money out of your pocket, and most of the ones that do work feature ingredients that are either harmful to the body or banned from use. None of them truly support muscle recovery or muscle growth. 

Today, we will be talking about a rather new pre-workout supplement that you might not have heard of before — Pre Lab Pro. We will be going into detail about everything you need to know about this supplement, including the ingredients, packaging, dosages, pricing, competitors, and more. So, let us dive into this Pre Lab Pro review to see if this pre-workout is the right choice for you!

Pre Lab Pro

What Is Pre-Lab Pro?

Pre Lab Pro is a pre-workout supplement brought to you by Opt-Nutra Ltd. It is the same company that brings you Mind Lab Pro — one of the most effective and popular nootropic supplements available today — and the rest of the Performance Lab Pro line of supplements, which includes Performance Lab NutriGenesis Multi, Performance Lab Stim, Performance Lab Energy, Performance Lab Omega-3, Performance Lab Burn, and many more. 

Their Pre Lab Pro supplement is marketed as a next-gen pre-workout formula that provides a bigger nitric oxide boost, smarter stimulation, and stronger homeostasis. It does so with the use of advanced ingredients, which provide a clean formula made with natural flavors and colors.

It is easy to whip up, it tastes like berry, it has a pink hue to it (red once mixed), and it is created with the right intentions. Their main goal with this formula is to give fitness enthusiasts of all different levels a safe and natural energy boost that supercharges their fitness goals daily, promoting bone health and helping them recover from intense and frequent workouts. 

The general ergogenic formula is one of a kind, meaning you will not find it anywhere else. It gives you the energy you need for your workout without screwing up the rest of your day, helping you achieve a new level of balance between your fitness, health, and overall lifestyle.

Pre Lab Pro-Natural Berry Flavor

Before we dive into the ingredients, let us first answer a couple of questions that might be swirling around in your brain — such as how much caffeine is too much, what is nitric oxide, what does homeostasis mean, and what’s the best way or time to take this pre-workout supplement. 

How much caffeine is too much caffeine? 

Caffeine comes in many different forms and is found in a wide range of different beverages. For example, a 12 oz. can of soda contains around 30-40mg, an 8 oz. cup of tea has 30-50mg, an 8 oz. cup of coffee has 80-100mg, and an energy drink has around 40-250mg per serving. 

Although it is not bad for you when taken in moderation and as part of a healthy diet, too much caffeine can have a wide range of negative effects on the human body. That is why you have to be careful with it. According to the FDA, we should never consume more than 400mg of caffeine in one day. 

Since most of us either drink coffee, tea, soda, energy drinks, or a combination of all four, we need to be careful when adding a pre-workout to the mix. Pre-workouts almost always contain caffeine, and most of them contain too much, so make sure you are aware of your daily intake. 

What does nitric oxide do for the body?

Nitric oxide is a molecule produced by just about every cell inside the human body. It is known as a vasodilator, which means it helps the inner muscles of your blood vessels relax and eventually widen. As a result, your blood pressure is lowered, and your blood flow is increased.

This is important when working out because it improves the delivery of both oxygen and nutrients throughout the body during exercise. This improves your performance in many different ways, ultimately helping you gain better results and have a better workout overall. 

Although supplements cannot contain nitric oxide directly, they can contain certain nutrients that help the body produce more nitric oxide. Nitrate and L-Citrulline are two of the most popular. While L-Arginine receives a lot of praise in supplements, it is not as effective as the other two.

Pre Lab Pro Ingredients

Now that we understand a little bit more about this product and what it claims to do for the body, we can start to break down the ingredients that make up the formula. This is where we get to put all those claims to the test and see this pre-workout supplement formula for what it is. 

Pre Lab Pro Ingredients

Vitamins & Minerals

For starters, we will look at the 8 different vitamins and minerals found in the formula. Each has its unique benefit for the body when improving your workouts. 

They are also all formulated with NutriGenesis technology innovation and refer to vitamins and minerals that are grown in live cultures in their very own state-of-the-art lab. They are bioengineered to be better and produce better results. 

Here is a look at what each vitamin and mineral does for the body:

  • Vitamin D – also known as calciferol, Vitamin D helps increase muscle protein synthesis, ATP concentration, exercise capacity, strength, and overall physical performance. 
  • Vitamin B2 –  called riboflavin too, this vitamin helps improve athletic performance by converting carbohydrates into ATP, which is stored as energy in muscles. 
  • Vitamin B6 – also known as pyridoxine, Vitamin B6 helps convert food into energy, creates red blood cells and neurotransmitters, and can improve mood. 
  • Vitamin B9 – commonly referred to as folate, helps convert food into energy and improves the overall function of the nervous system. 
  • Vitamin B12 – you might know it as cobalamin, Vitamin B12 helps convert food into energy, forms red blood cells, and ensures the brain and muscles communicate properly. 
  • Potassium – a mineral that regulates blood pressure, controls fluid balance, supports muscle health, improves muscle contractions, and maintains nerve function. 
  • Iron – a trace mineral that helps the body break down carbohydrates and ensures oxygen and nutrients are delivered to the areas that need it before, during, and after a workout.
  • Salt – Pre Lab Pro utilizes Himalayan Pink Salt, which improves pH balance, aids hydration, boosts circulation, reduces muscle cramps, and lowers blood pressure. 

As you can see, the vitamins and minerals listed above help the body in numerous unique ways when working out. Most of them help the body produce energy, but they also replenish certain nutrients that might be lost through sweat and promote muscle efficiency. 

Natural Caffeine – 80mg

Although Pre Lab Pro is not a stimulant-free pre-workout, it does contain natural caffeine sourced from Coffea robusta seeds, which come from the Coffea canephora plant. These seeds are heavily grown in the Eastern Hemisphere and are primarily found in Indonesia and Africa. 

Robusta seeds contain about twice as much caffeine as Arabica seeds, though they do not taste as satisfying as an Arabica seed — which does not matter in a pre-workout supplement. You will get about 80mg of caffeine from Robusta seeds in the Pre Lab Pro supplement formula.

As we all know, caffeine is a stimulant that mostly acts on the central nervous system. It increases energy and alertness, which can help you feel more awake and ready for your workout. Keep in mind that you should not consume more than 400mg of caffeine per day. 

L-Theanine – 160mg

L-Theanine is one of the few active ingredients found in green tea — along with caffeine. It is a non-dietary amino acid that is very similar to L-Glutamine and L-Glutamate. It can cross the blood-brain barrier and only takes about 30 minutes to reach the brain, where it does its job. 

You will often find L-Theanine in supplements that contain caffeine because the two work well together. L-Theanine is known to reduce the jittery effects and the crash that is associated with caffeine, which provides a more clean, calm, and relaxing energy boost that most people enjoy.

It can also lower blood pressure, boost cognitive function, boost alpha and theta brain waves, increase neurotransmitters in the brain, and protect your brain from over-stimulation. It is largely considered one of the most important nutrients anytime you consume caffeine or a stimulant.

L-Tyrosine – 400mg

L-Tyrosine is another amino acid, much like L-Theanine, and is very important when replenishing neurotransmitters that are lost when consuming caffeine. The body naturally converts L-Tyrosine into L-DOPA, which is a precursor to the neurotransmitter dopamine. 

In addition to providing a sense of reward and motivation, dopamine is also converted into two other neurotransmitters in the body — norepinephrine and epinephrine, also known as noradrenaline and adrenaline. These three neurotransmitters are known as catecholamines. 

Together, they help boost cognitive function (especially when under stress), boost the production of thyroid hormones, improve concentration, improve mood, and work synergistically with certain stimulants. It is naturally produced in the body thanks to an amino acid — phenylalanine. 

Setria Performance Blend – 2,200mg

Setria Performance Blend is a unique blend of L-Glutathione and L-Citrulline. Glutathione is one of the most effective antioxidants produced naturally by the body. Citrulline is also produced naturally and helps increase nitric oxide, as well as remove harmful substances from the body. 

Together, L-Glutathione and L-Citrulline make for a powerful nitric oxide boost with ergogenic effects on the body. It helps sustain blood flow longer than most other nitric oxide boosters, while also building and maintaining muscle mass, with a majority of the benefits coming post-workout. 

The Setria Performance Blend works well with the Red Beet Powder, which also improves nitric oxide production in the body. We will discuss more of that ingredient below, but the combination of the two allows for a nitric oxide boost now and later — a win-win situation.

Red Beet Powder – 1,500mg

Most of us know what beets are, but most of us are not aware of what red beet powder is. The good news is they are similar because red beet powder is nothing more than concentrated, dried beets that are grounded up into a powder. It is what gives Pre Lab Pro its pink/red color. 

Most of the benefits of red beet powder come from the presence of dietary nitrates. Nitrates are one of the best ways to increase nitric oxide in the body, along with L-Citrulline (which we mentioned above). They help increase blood flow and dilate blood vessels inside the body. 

Not only that, but beetroot powder helps improve heart health, maintains healthy blood pressure, improves circulation of oxygen and blood throughout the body, and improves overall athletic performance. It’s always a good thing to have some beetroot powder in a pre-workout.

How to Take Pre-Lab Pro

As you can likely imagine, a good pre-workout supplement is designed to be taken before you start your workout. It ensures you have the proper amount of physical and mental energy when you begin your workout, as well as gives you the nutrients to eventually get through your workout with flying colors. 

Since Pre Lab Pro comes in powdered form, all you need to do is mix one scoop of it in 12 ounces of water and drink it 30 minutes before your workout. It will normally take 30 minutes before you notice the effects, allowing you to time it perfectly with the start of your workout. 

If you want to, you can also take two scoops before your workout to increase the potency — just be aware of the caffeine intake and monitor the rest of your caffeine throughout the day. You can even take half of a scoop before your workout and another half in the middle of your workout for improved muscle strength. 

Pre Lab Pro works as a post-workout recovery providing your body with better muscle control while it boosts muscle recovery. Pre Lab Pro pumps your body with just about the right amount of ingredients to help prepare you for intense exercise. 

Pre Lab Pro Dosage, Packaging, and Pricing

There is something so unique and sleek about the Pre Lab Pro pre-workout packaging. It comes in your typical pre-workout tub, but it is a little more minimalistic than most. The tub is black, and the label is mostly black and grey with sleek, white block lettering. 

The front of the label states that it is a ‘Next-Gen Pre-Workout Formula,’ and the site states that it provides ‘Better Focus, Peak Performance, and Faster Results.’ It also has the ingredients listed clearly on the back, along with the dosages of each ingredient:

  • Vitamin D – 12.5mcg
  • Vitamin B2 – 500mcg
  • Vitamin B6 – 750mcg
  • Vitamin B9 – 167mcg
  • Vitamin B12 – 2mcg

Claims vs. Reality

There is not much to complain about regarding Pre Lab Pro. It has everything you need when working out but also does not contain anything you do not need — which is a major problem with many pre-workout supplements on the market today. It is an all-around excellent formula. 

The beetroot powder and Setria Performance Blend are the big go-getters in this formula, which both help increase nitric oxide production — both during and after your workout. The caffeine and vitamins help increase ATP production and give you that needed energy boost.

Since no one likes to experience jitters or crashes, which are associated with caffeine, Pre Lab Pro makes sure to add L-Theanine and L-Tyrosine to help reduce those effects. Not only that, but the Himalayan pink salt and other minerals help improve hydration and maintain homeostasis in the body.

So will Pre Lab Pro work as it promises? This pre-workout supplement does exactly what it says it will do, which is all you can ask for from a supplement. It is clean, safe, and effective for all fitness levels and goals. You can rest easy knowing that it can be used daily to help improve your workout day in and day out. 

Pre Lab Pro Competitors & Alternatives

With so many different pre-workout supplements available on the market today, you know that Pre Lab Pro is not going to be the only one that works. Despite there being so many that do not work, there are a few that you can trust outside of Pre Lab Pro, and we are going to detail some of them below. 

Of course, we would like to mention that Pre Lab Pro is one of the best. If you are looking for a new pre-workout, you definitely cannot go wrong with Pre Lab Pro. With that said, let us take a look at some of their competitors and alternatives for those that want something different. 

Energy Boost by Tone It Up

Alternative to Pre Lab Pro-Energy Boost by Tone It Up

Energy Boost by Tone It Up is largely marketed toward women fitness enthusiasts, but it can honestly be taken by men too. It is another safe, clean, and effective pre-workout supplement that comes equipped with a much simpler formula. It is a bit more expensive, though. 

The formula contains Vitamin B6, Vitamin B12, Magnesium, Sodium, and Potassium — all of which help increase energy and maintain electrolyte levels. It also has 100mg of caffeine (more than Pre Lab Pro) and 100mg of Ashwagandha Root Powder — an interesting addition.

Ashwagandha is an adaptogenic herb that helps the body deal with stress. It would have been nice to see L-Theanine added to this formula, but Ashwagandha is the next best thing. Each tub comes with 14 servings and will cost you $40, which means $80 for a one-month supply. 

Shroom TECH Sport

Alternative to Pre Lab Pro-Shroom TECH Sport

Shroom TECH Sport is a supplement brought to you by Onnit Labs. It is formulated to support both performance and endurance with the use of functional mushrooms, which are mushrooms that come with functional benefits beyond the nutritional benefits that most mushrooms provide.

The formula contains Vitamin B12, Chromium, a Shroom Tech O2 Blend, and a Shroom Tech Adaptogen Blend. The O2 Blend has cordyceps mushroom, which improves ATP production (energy). The Adaptogen Blend contains Ashwagandha, Green Tea, Rhodiola, and Astragalus. 

It is a simple formula that increases energy, relaxes the body, improves stress responses, and improves overall athletic performance. It is available in capsule form, though you have to take four capsules per serving. Each container has 21 servings and will cost you just under $60. 

Transparent Labs PreSeries STIM-FREE

Alternative to Pre Lab Pro-Transparent Labs PreSeries STIM-FREE

From the producers of Transparent Labs Bulk and Transparent Labs PhysiqueSeries Fat Burner comes Transparent Labs PreSeries STIM-FREE. So far, every pre-workout supplement we have detailed has had caffeine in it (Shroom TECH had Green Tea leaf extract), but with Transparent Labs PreSeries STIM-FREE, you can avoid caffeine and stimulants altogether. Instead, you get your energy from different and unique sources. 

The formula contains sodium, potassium, citrulline malate (nitric oxide), BCAAs, beta-alanine, betaine anhydrous, taurine, L-tyrosine, choline bitartrate, elevATP, BioPerine, and huperzine A. It is a bit more complex than the others, but it will get the job done without the use of a stimulant. 

It comes in powdered form, and each scoop is close to 23 grams of powder — almost double that of Tone It Up and Pre Lab Pro. That means it might not mix as well with water unless you mix it with a lot of water. Each tub gives you a one-month supply and will cost you just under $50.

Final Verdict: Pre-Lab Pro Review 

Pre-workout supplements can truly help you get the most out of your workout, but you must do your research and ensure that you are purchasing a safe and clean formula. The good news is that this is exactly what you get with the Pre Lab Pro formula.

It directly increases energy, helps the body produce a bunch of nitric oxide, and helps maintain overall homeostasis. That means you get your pre-workout boost without sacrificing the rest of your day to being tired, exhausted, and lazy. It is a win-win situation for everyone!

If you are looking for a pre-workout formula that stimulates muscle growth, can improve neuromuscular performance, supports all your workouts, and leads to optimal performance, all with a smooth energy boost, then this is the right supplement.

Enjoy the health benefits of Pre Lab Pro without any worries, you can get a full refund if you want.
