Burn Lab Pro vs Instant Knockout: Which One is The Best? (2023)
Here we have a comparison between two heavyweights in the fat burner market – Instant Knockout vs Burn Lab Pro. Which one is more effective at increasing your energy levels and focus, helping to control your appetite, and promoting natural fat burning? We bring their formulas face to face to give you the complete answer in this Burn Lab Pro vs Instant Knockout buying guide.
Burn Lab Pro vs Instant Knockout Summary
Both Burn Lab Pro and Instant Knockout are top-of-the-line weight loss supplements. However, between the two, Instant Knockout has a slight edge in our opinion.
It has been longer on the market (since 2015) and it boasts some of the best reviews out of any fat burner. Instant Knockout also contains more ingredients (9 vs 5), including 300mg of caffeine anhydrous to provide you with a lasting, strong, and clean “energy kick”. Burn Lab Pro is missing an appetite suppressant that is as good as the one in Instant Knockout, but it contains no caffeine.
The stim-free formula of Burn Lab Pro is still very potent though, and it might be the perfect choice for people who can’t tolerate stimulants. Both Instant Knockout and Burn Lab Pro give you excellent deals when buying in bulk, with Burn Lab Pro being just slightly cheaper.

But how will Burn Lab Pro work for you? Is it better than Instant Knockout?
Let’s find out…
Instant Knockout Overview
Instant Knockout Cut is a highly popular fat burner from the U.K specialist supplement company Roar Ambition. Instant Knockout was initially launched in 2015 as a solution for pro athletes to cut weight fast before fights. However, because it worked so well, it was later released to the general public.
In terms of how fast you can expect results from this fat burner, the answer is pretty fast. When it comes to reducing appetite, increasing focus, inducing thermogenesis, and enhancing fat breakdown, Instant Knockout is arguably the best on the market right now.
One thing that sets Instant Knockout Cut apart from other fat burners is that its formula gets updated every 6-12 months according to the latest clinical research and consultations with fitness experts. Instant Knockout is also endorsed by world-class MMA coaches and athletes such as Diego Sanchez.
It comes in a 120-capsule bottle, with a serving size of 1 capsule four times per day. This is a great way to dose a fat burner as it allows the nutrients to constantly circulate in your system – maintaining its fat-burning effects 24/7.

You may ask though, is Instant Knockout really as good as the marketing says? The best way to find out is to inspect its ingredients – and compare them to those of Burn Lab Pro!
Burn Lab Pro vs Instant Knockout Ingredients
Burn Lab Pro’s Ingredients
Here are the active ingredients in Burn Lab Pro:
- NutriGenesis® Chromium (90mcg)
- Calcium GMB (1500mg)
- ForsLean® (375mg)
- Capsimax® Cayenne Pepper Extract (75mg)
- Black Pepper Extract (3.75mg)
As shown on the label:

At first look, Burn Lab Pro looks like a really clean and impressive formula. It contains several patented ingredients, and there is no sight of fillers or unnecessary junk.
Additionally, the ingredient label is fully transparent with no proprietary blends. This is excellent!
Interestingly, Burn Lab Pro has decided to go the stimulant-free route. It uses no caffeine but still promises to give you just as impressive results as any caffeinated fat burner.
Looking at the ingredients in the formula, we believe Burn Lab Pro can indeed do what it claims.
The first on the ingredient list is chromium, an essential element that helps stabilize your blood sugars. When our blood sugar levels drop too low or shoot up too high, the result is grogginess, mood swings, lack of energy, and constant food cravings, and other annoying symptoms that some of us experience. Thanks to chromium blood sugar-balancing effects, you are far less likely to experience these issues.
Next up, we have a high-quality Coleus Forskohlii extract. Coleus Forskohlii is an Indian plant recognized for its testosterone boosting and fat-loss benefits. These effects are the result of the plant’s main active compound Forskolin. Forskolin is known to increase cellular levels of cyclic adenosine monophosphate (cAMP), a molecule that directly increases rates of fat loss. What’s more, Forskolin enhances the effects of other fat-burning compounds in Burn Lab Pro. The Coleus Forskohlii in Burn Lab Pro is standardized to 10% Forskolin. Considering its dosage of 375mg per serving, this delivers 37.5mg of Forskolin to your system, which is shown to be an effective and safe amount.
As we said, Coleus Forskohlii can enhance the fat-burning effects of other ingredients in Burn Lab Pro. This includes Cayenne Pepper Extract, one of the world’s most researched natural thermogenic. When combined with a calorie-controlled diet and regular exercise, Cayenne Pepper Extract is especially effective at raising your metabolic rate and signaling to your body to burn fat for fuel instead of glucose. And because Cayenne Pepper is thermogenic in nature, it works to keep your metabolism elevated even when you’re not exercising.
HBM is added to help protect muscle tissue from catabolism. Its neutralizing effects on muscle-wasting enzymes make it a solid addition for athletes, bodybuilders, and fitness enthusiasts who want to maintain as much muscle mass as possible naturally while cutting.
The formula rounds up nicely with Black Pepper Extract which augments the effects of other compounds in Burn Lab Pro, along with easing their digestion.
Could Burn Lab Pro’s formula be better? Sure. If they added another appetite suppressant like Glucomannan, and perhaps some caffeine to provide you with a stronger energy kick. But this is a personal preference. Many people will find Burn Lab Pro to work smoother than a caffeinated fat burner, while having a really impressive impact on fat-burning.
It’s clear the manufacturers of Burn Lab Pro wanted to develop a streamlined, no-fluff formula, and it worked out successfully in our opinion. What you see is what you get here.

Instant Knockout’s Ingredients
Here are the active ingredients of Instant Knockout Cut:
- Vitamin D3 (1800IU)
- Vitamin B6 (5mg)
- Vitamin B12 (10mcg)
- Glucomannan (1800mg)
- Green Tea Extract (500mg)
- Caffeine Anhydrous (300mg)
- L-Theanine (100mg)
- Cayenne Powder (100mg)
- Black Pepper Extract (10mg)
As shown on Instant Knockout’s label:

It’s clear Instant Knockout Cut has a larger formula than Burn Lab Pro. It contains 9 active ingredients compared to Burn Lab Pro’s 5. But is it better?
Let’s see.
One of the only ingredients they have in common is Cayenne Pepper. Which, as we said, is a highly effective thermogenic. It helps your body to burn more calories overall throughout the day.
Instant Knockout goes a step further by pairing with a strong dose of Caffeine Anhydrous (300mg). Aside from boosting our focus and energy levels, caffeine is a potent thermogenic too. The combined thermogenic effect of caffeine and cayenne pepper is synergistic – together, they produce much higher caloric expenditure than either one alone.
Speaking of ingredients that work well together, Instant Knockout has also included L-Theanine, which also works amazingly well with caffeine. L-Theanine is a compound from green tea that helps to reduce caffeine’s side effects (jitters, energy crashes, etc.) whilst enhancing caffeine’s positive effects on the mind and body.
Vitamins B6, B12, and D3 all work to support fat metabolism and keep your mood and energy levels stable throughout the day.
But possibly the greatest ingredient of all in Instant Knockout Cut (in our opinion) is Glucomannan. Also known as Konjac Plant, Glucomannan is a type of fiber that is especially effective for appetite suppression and hunger control. Upon ingestion, it mixes with fluids in your stomach to expand up to 100 times its original size. The result is a feeling of satiety and fullness that can last for several hours.
Much like Burn Lab Pro, Instant Knockout ties everything together with a high-quality Black Pepper Extract. At 10mg per serving, it works to ensure other ingredients get properly absorbed and utilized by your body, whilst enhancing the thermogenic effects of caffeine and cayenne pepper extract.

Which Formula Looks Better Overall?
In our experience, Instant Knockout Cut has a slight edge over Burn Lab Pro. Two reasons why: one is that it simply contains more of the good stuff. Vitamin D, Glucomannan, and L-Theanine are all excellent ingredients that not only help you burn fat, protect muscle tissue from catabolism, but also help you control appetite better.
Secondly, Instant Knockout has a potent dosage of caffeine to really give you a boost in calorie burning throughout the day while keeping your willpower and focus levels high to stay locked in on your goals.
That said, in the context of smoothness of effects, Burn Lab Pro probably has the edge. Even though Instant Knockout has ensured that caffeine’s effects are as clean and long-lasting as possible (thanks to L-Theanine), Burn Lab Pro may still be the better option if you’re sensitive to stimulants.
What do Others Say?
Both Instant Knockout and Burn Lab Pro boast excellent reviews online. Impressively, both supplements are endorsed by Pro athletes. In Burn Lab Pro’s case, that is Aljamain “Fun Master” Sterling, UFC’s bantamweight champion.
In the case of Instant Knockout, it features reviews from world-class athletes and trainers alike. This includes Grec Jackson, one of the world’s greatest MMA coaches.
However, since Instant Knockout has been longer on the market than Burn Lab Pro (2015 vs 2020) and since it has more positive reviews overall, we give it the slight edge in this department as well.
Burn Lab Pro vs Instant Knockout Side Effects: Which is Safer?
When it comes to side effects, there are next to no reports of Burn Lab Pro or Instant Knockout causing any, and we don’t think any will emerge. Why?
Because, both supplements use well-researched ingredients in clinical amounts. If you stick to the recommended dosages, it’s unlikely that either Burn Lab Pro or Instant Knockout will lead to negative reactions.
That said, since Burn Lab Pro contains caffeine and Instant Knockout contains 300mg of the stimulant, we think Burn Lab Pro has the edge here. If you really can’t tolerate caffeine, then it’s a no-brainer. Burn Lab Pro is as clean and as safe as supplements get!
Pricing & Value
Burn Lab Pro and Instant Knockout both come with some excellent deals. The price of a single bottle (1-month supply) is the same with both supplements – $59.
The good news is, if you decide to buy a 3-month supply of Burn Lab Pro, you get one extra bottle for free with fast international shipping, and the price drops to $44.25 per bottle.
Instant Knockout too has a 3+1 offer with fast and free international shipping, and the price per bottle is $46.25 in this case. Although slightly more expensive, we think Instant Knockout is well worth the price due to having a high number of premium ingredients that are safe, effective, and excellently dosed.
Takeaway
All things considered, which one is better: Burn Lab Pro or Instant Knockout Cut?
In our opinion, Instant Knockout has a slight edge over its competitor. Instant Knockout has been longer on the market and is trusted by some of the world’s top athletes and coaches. There’s a reason why Instant Knockout continues to be among the world’s leading fat burner supplements – it works. IKO’s formula is also being updated every year to keep it ahead of the pack. It is a tried and tested product that you can’t really go wrong with.
A similar story is with Burn Lab Pro, although we feel it’s missing that “kick” that Instant Knockout has. In addition, Burn Lab Pro doesn’t have a potent appetite suppressant like Instant Knockout. However, it does have the advantage of using HMB which is highly effective for protecting muscle tissue from destruction on a calorie deficit. Additionally, the lack of stimulants in Burn Lab Pro could be an advantage in some cases – for example, if you’re sensitive to stimulants. In that context, it could be a slightly cheaper and better option.
At the end of the day though, you can’t go wrong with either of these two. Both are highly effective for helping you to cut weight fast, whilst supporting your mood, energy levels, and appetite – setting you up for long-term success.
