A major priority of the health and fitness plans I put together for my clients is reducing fat cells and BMI, and Burn Lab Pro Fat Burner is a product that is frequently recommended to me for exactly this purpose.

When coupled with a careful diet plan, regular exercise, and even some intermittent fasting, fat burners can speed up the process of achieving your body composition and weight loss goals.

In this Burn Lab Pro review, we’re going to look at its mechanism, the ingredients and science behind it, and how/if you should take it yourself to burn fat and gain muscle mass.

Also, to avoid confusion, they recently got rebranded to Burn Lab Pro; the old name for these supplements was Performance Lab. So whenever you encounter Performance Lab or Performance Lab Sport, bear in mind that is the old name, but the same fat-burning supplement.

What Is Burn Lab Pro?

Burn Lab Pro Product on a table

Burn Lab Pro is a fat burner that may optimize fat loss without sacrificing muscle mass. It was previously known as Performance Lab Sport Burn Manufactured by UK-based Opti-Nutra in a GMP-certified facility.

Opti-Nutra calls Burn Lab Pro innovative. Its formula of plant-based ingredients promises to provide a calorie-burning boost, lean muscle growth, and accelerated recovery when combined with diet and exercise.

Burn Lab Pro can pass a banned substance test and contains no synthetic additives, artificial colors, or preservatives.

Burn Lab Pro is only available for purchase on the official website.

How Does Burn Lab Pro Work?

Burn Lab Pro works by triggering thermogenesis and lipolysis, which can start the fat-burning process in your body.

Generally speaking, body fat breakdown and weight loss will only happen if your energy expenditure is higher than your energy intake on a consistent basis.

That means that your exercise, training, and normal body functions need to use up or burn more calories than you take in through food. Only then may you burn fat and start getting that lean muscle mass.

The metabolic functions that target the storage of fat cells are called thermogenesis and lipolysis, and we’ll take a look at how this caffeine-free fat burner helps your body lose fat.

1. Thermogenesis

Opti-Nutra is a UK-based company, and they claim to have created a stimulant-free thermogenic supplement.

Essentially, this process involves slightly raising your body temperature resulting in more calories burned, which can lead to fat loss (1).

2. Lipolysis

Lipolysis is generally triggered through fasting and exercise. When your dietary energy doesn’t support all your energy needs for physical activity, then your metabolism will first target glycogen, and then fat (2).

9 Key Benefits

The Burn Lab Pro Fat Burner is a high-quality fat-burning supplement that helps you lose weight without losing muscle growth.

Besides the powerful weight loss formula, this supplement is beneficial for your health.

The regular use of this supplement can result in some of these benefits:

  • Blood sugar levels are stabilized
  • Thyroid function is improved
  • Improves the body's hormonal imbalance
  • Prevents fats from being stored in cells
  • Aids in the regulation of appetite
  • Increases the amount of energy you have
  • Fat oxidation and breakdown are maximized
  • Weight loss is maximized
  • Increases muscle mass

What Are The Ingredients?

1. HMB (HMB ß-Hydroxy ß-Methylbutyrate)

Supplement Facts for Burn Lab Pro

This abbreviation stands for ß-Hydroxy ß-Methyl butyrate formula, and you only need to remember it as HMB, often found among the ingredients in similar products.

This is the headline active ingredient, and the claim is that it can trigger the same fat loss processes as fasting [3].

Burn Lab Pro uses the calcium form of HMB (HMB-Ca), which is known to have higher absorption. However, it seems that recent studies confirm that the free acid form of HMB (HMB-FA) has better bioavailability and absorption than HMB-Ca [4].

HMB is a naturally occurring byproduct of leucine breakdown. It behaves similarly to leucine in the body; both independently increase muscle protein synthesis and inhibit muscle protein breakdown, though leucine is better at causing protein synthesis, and HMB is better at inhibiting protein breakdown and also mitigating muscle damage in response to training.

2. Coleus Forskohlii

Coleus Forskohlii

The ForsLean® or coleus forskohlii root extract has been added to a thermogenic fat burner claiming that this ingredient triggers thermogenesis and helps regulate metabolic hormones [5].

One study conducted in 2015 showed that when combined with a calorie deficit, coleus forskohlii or ForsLean can help regulate metabolic rates, which is why it is commonly used in supplements.

3. Cayenne Pepper Extract

Cayenne Pepper Extract

Now, before you think that Capsimax cayenne pepper, like any other chili pepper, will burn away your taste buds and cause all sorts of stomach upset, this extract will do no such thing [6].

Cayenne pepper extract in all its nutrient forms has long been known to work well as a fat burner and an appetite suppressant, but a recent detailed study was able to draw a scientific link with its ability to burn fat.

That's why you'll find this chili pepper extract as an ingredient in some of the best weight loss supplements.

4. Black Pepper Extract

Black Pepper Extract

Similar to cayenne, BioPerine black pepper is known to stimulate thermogenesis, but this ingredient has a little weight-loss bonus attached to it. One study has shown that BioPerine black pepper extract can inhibit a process that leads to excess energy being stored as fat [7].

Combined with all the other ingredients, this means that thanks to the BioPerine ingredient, you’ll be more likely to lose weight and keep it off at the same time.

5. NutriGenesis® GTF Chromium

This trace mineral, presented as Glucose Tolerance Factor (GTF), is known to enhance insulin activity, promoting significant fat loss. It contains whole-food cofactors that can boost its absorption and bioavailability for faster results.

Research shows that it may improve insulin sensitivity, which can help regulate appetite, stabilize energy, and improve endurance to cause fat loss. It is also proven that among different forms of chromium, GTF performs the best in reducing insulin resistance [8].

  • Quick results, with proper diet and exercise, seen in as little as two weeks

Burn Lab Pro Side Effects

All the ingredients are generally classified as safe to take. Unless you have a known allergy, there shouldn't be any reason for this product's concern and potential side effects.

Based on reading hundreds of reviews, my clients' experience, and my test results, one side effect did show up.

It messed up my bowel movement and caused an upset stomach. This experience was evident during the first few days of trying it out.

If you're considering taking this fat loss supplement, I suggest taking it at a lower dose for a few days and just avoiding taking it whilst fasting.

Who is Burn Lab Pro Right For?

Burn Lab Pro is right for athletes and people who are willing to put in the most effort. It is a program that is designed to improve your body composition in a real and apparent way.

If you're not driven to work hard in the gym and eat well, this product is probably not for you. Burn Lab Pro is not a game for the faint-hearted.

But, if you're the type of person who is prepared to put in the effort and use Burn Lab Pro, you'll get the same outcomes that so many others have.

When Should You Take It?

You should take two capsules of Burn Lab Pro 15 minutes before you start training for maximum benefits. This allows your stomach to absorb the active ingredients for them to start kicking into action in time.

The idea behind combining it with a training session is that your body will trigger normal fat-burning processes through physical activity, and Burn Lab Pro burns more calories that will give your moves that little bit of an extra boost.

How Long Does it Take to See Results?

It takes 10 to 14 days to see first results, if you take the recommended dosage combined with a proper diet and exercise routine.

In general, you'll see effects after two weeks, with fat loss steadily increasing after that. It may take an extra week or two for you to detect changes on the scale, but you should notice a significant transformation after a few months of use.

Where To Buy Burn Lab Pro?

Where To Buy Burn Lab Pro?

You can buy Burn Lab Pro from the company website. While Amazon has plenty of offers, you won’t get a better bulk offer per bottle than directly from Opti-Nutra.

It’s also the only way you can really guarantee you’ll receive the real product. There are so many counterfeit products out there, and when it comes to something that you put in your body, there’s no way you should take any risks.

Burn Lab Pro Pricing & Guarantee

Burn Lab Pro is, without a question, the most advanced fat burning supplement on the current market. It has everything you'd want: it is safe, made with tested ingredients, and has a great reputation.

There are numerous purchasing options available on the official website:

  • $59.00 for one month's supply
  • $118 for a two-month supply
  • $177 for a four-month supply

Your first fat burners purchase comes with a 30-day money-back guarantee, regardless of what you buy. If you don't see any results, you'll get a complete return of your money.

Fat Burner Alternatives

PhenQ

phenq

PhenQ is considered one of the most effective fat burners that use ingredients that are 100% natural to target five angles to lose weight: reduce stored body fat, suppress appetite, block fat production, increase energy levels, and boost focus and motivation.

Unlike Burn Lab Pro, which uses HMB and Coleus Forskohlii, it contains caffeine to boost metabolism, L-carnitine to enhance energy, and nopal to regulate your appetite.

These fat burners are a bit pricier than Burn Lab Pro, but it's a 5-in-1 weight loss pill that's proven to work for both regular people and bodybuilders.

LeanBean

Leanbean

Similar to Burn Pro Lab, LeanBean is a 100% vegan-friendly, all-natural fat burning supplement that aims to boost thermogenesis and control appetite for a more effective weight loss.

It contains a small dose of natural caffeine, thermogenic ingredients like green coffee bean and turmeric, appetite suppressants like glucomannan and chromium, and B vitamins for reduced fatigue and immunity support, which you won’t see in Burn Lab Pro.

The only downside is you would need to take 6 capsules per day, compared to just 3 with Burn Lab Pro.

But apart from that, it’s a female-friendly fat burner and appetite suppressant that can help women shed excess fat and curb cravings.

Instant Knockout

Instant Knockout Box

Instant Knockout Cut, like Burn Lab Pro, is a 100% vegan-friendly fat burning supplement that accelerates metabolism and thermogenesis to lose weight.

But unlike Burn Lab Pro, which only targets fat burning and appetite suppression, it contains caffeine and green tea extract to promote thermogenesis, glucomannan to curb appetite, and L-theanine to improve memory and focus.

It’s originally formulated for bodybuilders and performance athletes, which can explain why almost all its ingredients are in high doses compared to those in Burn Lab Pro.

Is Burn Lab Pro Worth Buying?

Based on all the research I've done, along with many hours of carefully browsing through pros and cons, reading online review comments, and some personal experience, I have to say that ​Burn Lab Pro Fat Burner is a decent product.

However, I'm on the fence about whether it is one of the best fat burners, as it did cause a few digestive issues when I tried it out. One best fat burner that, by far, hasn't disappointed me nor caused any adverse reactions is PhenQ.

As long as you use the PhenQ fat burner alongside a healthy diet, some intermittent fasting, and continue to push it in the gym, this product can work in conjunction with your body to shed excess weight. This weight loss supplement is designed to help you burn fat cells the right way.

  1. I’ve had a similar experience with this product, too. Even if you ate something before taking it, it still unsettled your stomach, made you feel sick and made you feel like you were about to vomit. According to the instructions, start with one capsule. I attempted to increase to the required two twice a day but felt worse and dizzy as if I were lying down and not exercising.

    1. Thanks for taking the time to share your experience, Thomas. I’m sorry to hear that you had a negative reaction to Burn Lab Pro. I guess we’ve all had some unique side effects from this. Like all supplements, it works in one body and it does not with others.

  2. So far, I’m pleased with the outcomes. I went from Burn XT to Burn Pro series, and it appears like I’m still progressing. Feel more slender. It effectively suppresses my appetite. I haven’t felt sick at all. It is a lot of tablets to swallow, but it isn’t a big deal.
