Performance Lab Burn Review

Obtaining a fit body is much easier said than done. It takes extreme grit, determination, dedication, and will. While some people have an easier time obtaining and maintaining the body they want, others have a much more difficult road to success when losing fat and toning their bodies.

It’s frustrating when you feel like you’re doing all the right things, taking the proper steps, and making the necessary lifestyle changes to effectively burn fat, but aren’t met with the expected results. If this sounds like you, don’t be ashamed to seek help from supplements.

Today, we’re discussing one of the most popular fat burners available — but it doesn’t work like most fat burners. Let’s take a look at what makes this stimulant-free fat burner so special in this review of Performance Lab Burn.

What Is Performance Lab Burn?

Performance Lab Burn is one of those 9 supplements and is designed to help you burn fat — the right way.

Now that we understand a little more about the company, let’s start to take a look at the science behind what this product is supposed to do.

How Does The Body Burn Fat? 

To give you a simple answer, the body burns fat when more calories are burned than consumed in a given period of time. Since a fat cell’s primary responsibility is storing fat for future use, your body is forced to make more fat cells the more you eat a calorie-rich diet.

Generally, fat storage is a good thing when moderated. We all need fat on a daily basis because it ensures we have energy when glucose isn’t available. They’re also required for keeping the body warm and protecting organs.

Too many fat cells — as well as enlarged fat cells — eventually starts to damage the normal function of the fat cell, which causes it to release energy at a lower rate and release other hormones at a higher rate. This begins a frustrating cycle that leads to more fat cells and a higher risk of obesity.

The easiest way to combat this is by eating a healthy diet and ensuring you lead an active lifestyle, which causes fat cells to use the stored energy in fat cells and eliminates the need to store that much energy in fat cells for the future.

Unfortunately, most people in today’s society do the opposite by eating unhealthy foods and spending large amounts of time sitting or lying down. This teaches your body to store fat because it knows you won’t be needing it anytime soon.

Why Do Most Fat Burners Use Caffeine? 

While most people turn to fat burners when trying to lose any excess fat, they’re often met with adverse side effects that aren’t worth the trouble. This is why most people feel stuck with the body they’re given, especially when they’ve tried everything else.

One of the main reasons fat burners can be dangerous is because they generally aren’t regulated by the FDA and often contain large amounts of caffeine. While caffeine speeds up your metabolism and causes you to use stored energy, it’s not a reliable way to lose fat and won’t be sustainable.

In fact, caffeine won’t effectively help you lose fat or weight unless also met with a healthy and active lifestyle. That’s why fat burners don’t work for most people — people stop doing all the other right things that are necessary for success.

In addition to that, most of us already consume enough caffeine as it is. We don’t need to add any more to our diets and are actually better off limiting the amount of caffeine we consume on a daily basis.

Can Performance Lab Burn Be Used With Fasted Training?

In addition to being a stimulant-free supplement, Performance Lab Burn is also the perfect addition to your fasted training regime. Fasted training has become extremely popular in the new decade, but it’s difficult to find supplements that cater to this.

Fasted training is when you work out on an empty stomach. It forces the body to use stored fat as energy since there’s no blood sugar or glucose to function properly. This promotes fat loss and weight loss when working out, especially since energy demands are much higher than normal.

Performance Lab Burn works to not only maximize the effects of fasted training, but also limit the various downfalls to fasted training — including the reduced intensity and increased muscle degradation.

What Other Claims Are Made About Performance Lab Burn?

In addition to being free of stimulants and excellent for those that love engaging in fasted training, Performance Lab makes a wide range of claims about their supplement that consumers should be aware of.

To ensure you make an informed buyer’s decision when shopping for this supplement, we’re going to take a look at the other claims made.

  • Helps build muscle and improves body composition
  • Promotes the breakdown and mobilization of fat
  • Helps burn more calories when working out
  • Free of allergens, banned substances, gluten, soy, synthetic additives, and caffeine
  • Non-GMO, non-irradiated, GMP-certified, and vegan-friendly
  • Regulates blood sugar and appetite, while limiting fat storage

As we move through this review, we’ll be able to clearly see whether or not Performance Lab hits home with any of these claims — allowing you to decide whether or not it’s worth your hard-earned money.

Performance Lab Burn consists of six main ingredients — calcium, chromium, HMB, ForsLean, cayenne pepper extract, and BioPerine. We’ll take a closer look at each ingredient individually to see what they are and how they’re supposed to help the body burn fat.

Performance Lab Burn Dosage, Packaging, & Pricing

Performance Lab Burn features a rather simple packaging design, but it’s synonymous with the rest of their product line and helps increase how recognizable it is. The bottle is white with a gray label, while the box it comes in is all gray.

There’s a big square on the front of the bottle and box that’s a red-orange gradient color, with the name of the supplement — Burn — listed below. All the ingredients, nutrient facts, and directions are located on the back of the box and bottle.

Here’s a look at the dosages of each ingredient per serving:

  • Calcium – 175mg
  • Chromium – 60mcg
  • Forslean – 250 mg

Each serving is two capsules, and each bottle comes with 60 capsules inside, meaning one bottle lasts you a month when taking two capsules per day. It’ll cost you $50 per bottle, but you can receive a free bottle when you purchase three.

Performance Lab Burn Pros vs. Cons

Performance Lab Burn does an excellent job of helping the body burn fat and also helps solve a lot of the issues people run into with most fat burners on the market today. Still, that doesn’t mean this supplement is perfect and without flaw.

To ensure you understand everything there is to like and dislike about Performance Lab Burn, we’re going to discuss the major pros and cons of this fat burner. It’ll also act as an accurate summary of everything we’ve discussed up to this point in the review.


  • Performance Lab is a credible supplement company that uses research-backed ingredients
  • They ensure their products are safely and properly made by complying with rules, regulations, and certifications
  • BioPerine is proven to help increase nutrient absorption
  • Chromium plays a role in insulin action and metabolism
  • Cayenne Pepper increases energy expenditure and fat metabolism
  • Foskolin has studies suggesting it improves fat loss and muscle gain
  • HMB helps improve the fat-burning process and decreases muscle damage
  • Can be used daily and paired with other Performance Lab supplements
  • Overall, helps burn fat and improves the way the body uses fat — opposed to storing it
  • Utilizes prebiotic-infused capsules that help improve digestion
  • Great for those who love to fast and are looking to avoid caffeine or other stimulants
  • Free of allergens, banned substances, gluten, soy, synthetic additives, and caffeine
  • Non-GMO, non-irradiated, GMP-certified, and vegan-friendly


  • Can be expensive when buying one bottle at a time
  • Need to take two capsules per serving, instead of just one
  • Can’t be used as a replacement to exercise and a healthy diet
  • Won’t see results right away

Claims vs. Reality

Performance Lab is known for being careful, honest, and transparent with their supplement formulas. Things are no different with Burn, as it boasts an extremely safe and effective fat burner to help people reach their weight or composition goals.

The Forskolin and HMB are the major players here. While more research is needed to further cement these two nutrients as highly-effective fat-burners, there are studies suggesting positive signs for both muscle growth and fat loss.

The mixture of Chromium, BioPerine, and Cayenne Pepper add to the metabolic, thermogenic, and digestive benefits this formula offers.

Unfortunately, this product won’t do what most people assume it does. It won’t act as a replacement for eating healthy and living an active lifestyle. Instead, it must be used in accordance with these two things in order to be effective.

The good news is Performance Lab Burn won’t claim to be a replacement — consumers assume it’ll be and then get angry when they don’t see results.

Other Performance Lab Burn Supplements

Most fat burners on the market today either feature large amounts of caffeine or other supplements. The ones that boast a stimulant-free formula generally cut corners elsewhere in the formula. With that being said, it’s difficult to find a fat-burner that compares to Performance Lab.

Instead of discussing competitors and alternatives, we’re going to highlight some of the other Performance Lab supplements you can use in conjunction with their Burn supplement — that way, you get an enhanced experience when aiming for the body of your choice.

Performance Lab Stim

Performance Lab Stim

As we mentioned above, Performance Lab Burn is a stimulant-free supplement and provides an energy boost indirectly — unlike caffeine. With that being said, some people enjoy stimulants when working out, and they can be helpful when taken as directed.

Performance Lab Stim combines 50mg of natural caffeine from Coffea robusta seeds with L-Theanine (reduces jitters and crash), and L-Tyrosine (focus and concentration). It also utilizes several different vitamins essential to the energy process.

What I like about this stimulant supplement is it does much more than provide energy. With the vitamins, L-Tyrosine, and L-Theanine, your body receives relief from the side effects of caffeine to further balance and recover yourself. It’ll stack well with Performance Lab Burn.

Performance Lab MCT

Performance Lab MCT

MCTs are commonly found in coconut oil and have become an extremely popular ingredient in keto supplements. It’s also commonly used by people who frequent fasted training regimes due to its ability to raise ketone levels in the body and brain.

Performance Lab MCT Oil comes in oil form and can be added to just about any beverage, smoothie, or taken directly. Every 15ml contains 7.1 grams of caprylic acid and 5.1 grams of capric acid. It’ll also contain 130 calories.

Each bottle lasts you about a month and can be purchased online for $34 per bottle. It’ll stack well with Performance Lab Burn, allowing you to improve your fat loss and weight loss progress — especially when following a keto diet and engaging in fasted training.

Performance Lab Pre & Post

When we workout, we want to know that we’re getting the most out of every workout possible. Otherwise, what’s the point, am I right? Unfortunately, this can be difficult to maintain on a daily basis without the right supplemental help.

Performance Lab Burn can definitely help with the fat loss and weight loss, as well as providing a natural energy boost, but your body can use even more of a boost to get you through your workout properly.

If you’re searching for a muscle-pumping, muscle-preserving, fat-blasting sensory workout regime tailored for success, combining Performance Lab Pre and Post supplements can help you get there. It’ll also work well with your Burn supplement.

Performance Lab Post

Final Verdict: Performance Lab Burn

There’s a lot to like about Performance Lab Burn. It’s safe and utilizes ingredients that focus on burning fat without the use of a stimulant. It follows all the core values of an effective fat-burning supplement and easily blows its competitors out of the water.

If you’ve already made all the right lifestyle changes but aren’t seeing the type of results you were hoping for when trying to lose fat and weight, Performance Lab Burn could be the missing link to all your issues.

Not only will it help train your body to use fat as energy instead of storing it for later use, but it will improve the way your entire body functions and promote an improved wellness all-around. Use Performance Lab Burn with their other supplements to maximize the amount of benefits you receive when working out and eating healthy.
