Overview
Instant Knockout Cut was first developed for fighting sports such as boxing and MMA, where aggressive cuts (dropping body fat) are a crucial part of the pre-fight training. Fighter’s need to operate in a calorie deficit, they need to train hard and focus.
Cut allows this to happen. Not only does it help to rev up your metabolism and reduce your appetite, but it also devotes itself to boosting your mood and increasing focus. It offers:
- Appetite suppression
- Metabolic boost
- Fat oxidation during exercise
- Boosts mood and focus
- Fully dosed ingredients
Why the Formula Works
Cut contains a lot of smart ingredients. Most of the work is performed by the 300 mg of caffeine and the 1800 mg of glucomannan. There is also 500 mg of green tea extract, and 1800 IU of vitamin D. Cayenne pepper is effective at raising your metabolism and improving insulin sensitivity [1]. The caffeine is well dosed, but due to the serving being split into four pills you should not see any side effects from it.
The green tea is well dosed and should help with fat burning as well as improving blood flow. It can also help to increase HDL (good) cholesterol while lowering LDL (bad) cholesterol [2]. Black pepper extract is added to increase absorption, and l-theanine is added to improve your mood, reduce stress [3], and due to its synergistic relationship with caffeine.

How to take
For best results, you want to take one capsule four times per day. For example, one at 8am, one at 11am, one at 2pm, and one at 5pm. This helps to increase the amount of time that your body is burning fat and reducing hunger, it also helps to prevent side effects from the caffeine and cayenne pepper extract. If you go to bed early, then take your fourth pill before 3pm rather than 5pm as it contains caffeine.
Pros
- Well chosen ingredients that are properly dosed
- Suppresses appetite, making it easier to maintain a calorie deficit
- Boosts metabolism to help you burn calories
- Theanine reduces stress and anxiety
- Caffeine helps you to focus
- Glucomannan helps you feel fuller for longer
Cons
- Only available from official website
Conclusion
Instant Knockout Cut is a powerful fat burner, and a superb appetite suppressant. It allows you to function and thrive while in a calorie deficit, making it easier to maintain your diet for as long as required. Its mood enhancing and cognitive benefits are a real game changer, and the improved focus and concentration will seriously improve your experience.
Overview
Hunter Burn has a very different approach to fat burning than Instant Knockout Cut, and it really depends on what your goals are as to which supplement suits you best. Hunter Burn places most of its emphasis on appetite suppression.
Using konjac root extract and white kidney bean extract to reduce appetite, improve digestion, and lower cholesterol. While using matcha green tea and cayenne pepper to increase fat oxidation and burn more calories. Hunter Burn also packs its formula with 3000 IU of vitamin D, which has been shown to burn fat in overweight and obese people [4].
Hunter Burn is packed full of powerful ingredients, which provide the following benefits:
- Effective carb blocking ingredients
- Reduced cravings between meals
- Raises your metabolism via thermogenesis
- Supports healthy hormone production
- Relaxes and reduces anxiety
Why the Formula Works
The ingredients in Hunter Burn are split into three categories: Hunger neutraliser, thermo-burn, and energy unlock. The first category contains konjac root, also known as glucomannan, which has the ability to help you feel fuller for longer, and to reduce cravings between meals. Then there is white kidney bean extract, which works as a carb blocker. Helping to prevent your body from extracting as many calories from carbs as usual.
The thermo-burn category contains cayenne pepper and matcha green tea, which can boost your metabolism and help to burn more calories by temporarily raising your body temperature. Energy unlock contains a decent serving of vitamin D, and l-theanine, an amino acid that has stress relieving properties.

Overview
Burn Of The Gods: Ultimate Shred differs from the other options on this list in that, while the other entries come in capsule form, it is a powdered drink mix. This makes it ideal for people who have issues with or don’t like swallowing capsules. Available in a range of flavours that include Athena’s Mixed Berry, Atlas Apple, Gaia’s Passion Melon, Gryphon’s Grape, Medusa’s Lime, Rhea’s Raspberry, and Zeus’s Orange, there are options to suit all palates.
Burn of the Gods: Ultimate Shred is designed to make your weight loss journey more achievable, energising, and empowering. It aims to help you stay focused, eliminate cravings, give you insane energy to complete the kind of long, hard workouts required for weight loss, and even keep you healthy as you march towards the results you’ve earned. This is while being free from artificial additives or fillers.
- Provides a significant energy boost
- Helps keep cravings in check
- Doesn’t require you to swallow any pills or capsules
- Promotes direct fat burning
Why the Formula Works
The Burn Of The Gods: Ultimate Shred formula relies heavily on 4 ingredients: apple cider vinegar powder (1,500 mg per scoop), saccharomyces cerevisiae (DNF-10)(500 mg per scoop), L-tyrosine (400 mg per scoop), and caffeine (100 mg of Zum XR Caffeine Extended and 100 mg of Zum XR Caffeine Instant per scoop).
The high-acetic acid Apple Cider Vinegar boosts your metabolic rate, DNF-10 helps with appetite control, and caffeine provides long-lasting energy and focus, while burning fat directly. The two different types of caffeine have been included to prevent the jitters and crashes that often occur when using high-dose caffeine supplements.
The formula then supports its main ingredients with smaller doses of green tea powder, Theobroma cacao powder, juniper berry fruit powder, Siberian ginseng root powder, blueberry powder, Aframomum melegueta fruit powder, black pepper powder, chromium, vitamin B5, vitamin B12, and vitamin C. These are included to both enhance the effectiveness of the main ingredients while helping keep your body healthy as you lose weight.

How to take it
Burn Of The Gods: Ultimate Shred can be taken in servings of either 1 or 2 scoops, which should be mixed with 250ml to 300ml of water. For best results, it should be taken roughly 30 minutes before a workout on training days or as early in the morning as possible on rest days. This is to prevent its high caffeine content from causing sleep problems.
Pros
- Contains many proven natural fat-burning ingredients
- Does not require you to swallow any pills or capsules
- Available in a choice of flavours
- Provides a significant energy boost
Cons
- Many of the ingredients still need more research
- Requires a lot of work on your part to see great results
Conclusion
Burn Of The Gods: Ultimate Shred is a unique weight loss supplement, as it doesn’t require you to swallow the pills or capsules that traditional supplements in this niche do. It is also a great option for those seeking a supplement that doubles as both a fat burner and a pre-workout, as it provides the energy to power through long, tough workouts, burning fat and calories, while accelerating fat metabolism on its own.
That is not to say it is a perfect product or one suitable for everyone, though. Not only does it require a lot of work on your part to produce truly impressive results, but it also contains many ingredients that require far more research to prove they are actually beneficial for weight loss.

Transparent Labs Fat Burner Stim-Free is a good stim-free option and contains a well-studied formula. The natural fat burning ingredients combine to boost the rate of thermogenesis and lipolysis, whilst dealing with the way your body handles stored fat. By amplifying the rate at which you use fat for fuel, you may experience some good fat loss with this product. It’s a great option for anyone sensitive to stimulants and those who struggle with low mood and motivation when on a calorie restricted diet plan.
Overview
The final fat burner on our list is Burn Lab Pro. Another stim-free fat burner, which focuses on appetite suppression and raising your metabolic rate via capsicum and chromium. The number one focus for Burn Lab Pro is to help you to maintain muscle and energy levels while dieting, which is a unique approach, and one that will suit some people really well.
The ingredients list is interesting, and offers the following benefits:
- Natural fat burning
- Thermogenic, to boost your metabolism
- HMB preserves muscle while in a calorie deficit
- Controls appetite and optimises insulin
Why the Formula Works
The main ingredient in Burn Lab Pro is Coleus Forskohlii. There is evidence that it can help to burn fat and may help to boost natural testosterone production in overweight males [9]. That same study saw a minor increase in lean muscle mass alongside the fat burning and testosterone boosting effects.
Coleus Forskohlii also appears to improve cholesterol levels, increase energy, and improve bone density. All of these benefits were noted in the same study, and it would be useful for there to be more follow up studies in the future. We’ve looked at capsicum in the previous entries, and we like it as a fat burning ingredient.
You’ve also got HMB which has some good evidence for burning body fat, a study on female judo athletes found statistically significant drops in body fat over a 7 day period [10]. Burn Lab Pro also provides chromium, which can help to reduce appetite (particularly for carbs) and also has mood boosting properties [11].

Want to try Burn Lab Pro?
How to take it
The website recommends taking Burn Lab Pro 15 minutes before you exercise and says you should take 2-4 capsules. The idea is to preserve your muscle and increase fat burning during the workout itself.
Pros
- Preserves muscle mass during weight loss
- Carb and food cravings suppressed
- Fat burning from capsicum and HMB
- Improved bone density
- Good price
Cons
- Doesn’t burn much fat compared to others
- Too reliant on Coleus Forskohlii
- No mood enhancing ingredients
Conclusion
There is a lot to love about Burn Lab Pro, it puts a lot of effort into preserving muscle mass during a weight loss period, and it is designed to work well with exercise. But for a fat burning supplement it doesn’t do enough to actually burn fat! Capsicum is a decent ingredient, but the other supplements on this list use it alongside other well-known fat burning ingredients. Whereas Burn Lab Pro is over reliant on it.
It also puts a lot of faith in Coleus Forskohlii, which admittedly has a lot going for it, but not much scientific evidence, just one creditable study. This makes it hard to assess, because usually you want a bit more evidence backing your ingredient before you place it as the number one ingredient in your supplement.
