- Excellent dose of chromium - more than we need!
- Very good serving of chili extract
- No appetite suppressant
- No green coffee bean extract
- Choline not effective for enhancing focus; must use analogues
Reflex Thermo Fusion is not a bad fat burner at all. It will probably give a lot of you some good results; you’ll see faster fat loss, higher energy levels, and better blood sugar control. However, it is far from the best fat burner we’ve ever reviewed. The formula has serous limitations. The main limitation is the lack of a proven, effective appetite controlling substance. It is also disappointing to see that Reflex have opted for straight, basic choline for Thermo Fusion. If you want optimal results, then you’re going to have to use a more advanced fat burner.
Our Thermo Fusion Review
Reflex Nutrition are one of the best sports supplement brands to come out of the UK. These guys have an amazing reputation for producing high quality, no-nonsense bodybuilding supplements. Their main selling point is the quality of the ingredients they use. Their protein powders and weight gainers in particularly are extremely popular because of the effort they put into ingredient quality.
Thermo Fusion is their leading fat burner.
So what does it claim to do?
Who is it for?
According to the Reflex Nutrition website, Thermo Fusion is primarily a chromium supplement. The main stated benefit is the fact that it delivers a large dose of high quality, highly bio-available chromium.
Reflex state that Thermo Fusion helps you maintain normal blood glucose levels and supports healthy, normal metabolism.
Clearly, this is not an extreme, hardcore, heavy duty fat burner. Thermo Fusion is not the same as many of the fat burners reviewed on this site; it doesn’t claim to do much more than help support health blood sugar control and speed up metabolism.
So, does it really work?

Thermo Fusion Formula
Let’s have a look at the Thermo Fusion formula and see what this fat burner is really capable of:
That’s quite an interesting formula – there’s certainly more to Thermo Fusion than chromium!
We don’t know why Reflex bill this as a chromium supplement with some added extras; this actually looks like quite a complete fat burner.
Thermo Fusion covers more bases than some other supplements which claim to be full spectrum, comprehensive fat burners!
There are some great ingredients in here. Taking these ingredients together will definitely increase fat loss, improve performance in the gym, and help you get through your cut much more easily.
It isn’t a perfect formula of course. There are several flaws in the Thermo Fusion formula which we think hold it back from being a truly great fat loss aid.
For example, there’s no real appetite suppressant in Thermo Fusion. Nor is there any green coffee bean extract (a staple in modern fat burners).
Reflex also used choline as a nootropic. This is probably the least efficient way to increase acetylcholine levels in the brain; it’s much better to use a choline analogue like Alpha-GPC.
We also have no idea why phenylalanine finds its way into so many fat burners – IT DOESN’T DO ANYTHING!
But aside from these – admittedly serious – flaws, Reflex Thermo Fusion is a solid fat loss aid.
Let’s go through the main weaknesses and strengths in more detail.
- Solid serving of Cayenne Pepper Extract
- Sensible Caffeine dose
- Provides plenty of Chromium
We think the Thermo Fusion formula is flawed in several ways. But that does not mean that it is a bad fat burner. Quite the contrary; we think this is a solid supplement capable of delivering real results for the vast majority of users.
Thermo Fusion has several major strengths.
The thing we probably like most about this stack is the large dose of Chromium.
Chromium is a very important mineral in the human body. It often gets overlooked; it isn’t as well-known as the likes of iron, zinc or magnesium. But that isn’t because it isn’t as important for health, fitness and performance.
Chromium’s main purpose in the body is to regulate the metabolism of fats and carbohydrates. Chromium also promotes cholesterol synthesis – which is needed for testosterone and brain tissue creation – and fatty acid metabolism (source).
More relevant to fat loss is chromium’s effect on insulin. Basically, chromium supports normal insulin function. It is needed for insulin to do its job properly. Without sufficient chromium availability, insulin can’t efficiently shuttle nutrients to your cells.
Each serving of Thermo Fusion contains 100mcg of Chromium, or 250% of your RDI. That is far more than you get from even the highest quality fat burners out today.
Another big positive of Thermo Fusion’s formula is the large dose of Cayenne Pepper Extract.
We’re sure you’re all intuitively aware of how this ingredient helps during a cut. But you might not fully grasp how consuming spicy chili can accelerate fat loss.
Caspaicin – the oil which makes chilis ‘hot’ – is an irritant. The body ‘interprets’ it as heat. So when you consume capsaicin (from cayenne peppers, for example), the body triggers a heat response. You start sweating, your blood vessels dilate, and your breathing becomes deeper.
All of this costs calories.
Lots and lots of calories.
Consuming capsaicin-rich extracts like cayenne pepper extract is a great way to turn yourself into a walking furnace. You can turn up your internal body temperature and take advantage of the extra calories your body will expend to keep cool. This effectively puts you into a deeper relative caloric deficit, which means faster fat loss without having to cut more calories!
Thermo Fusion contains 200mg of Cayenne Pepper Extract. Again, this is actually more than we get from some of the highest quality fat burners out right now.
- No appetite suppressant
- No green coffee bean
- Choline not effective at raising choline levels in the brain
Despite the major benefits outlined above, we aren’t overly optimistic about Thermo Fusion’s potential.
There are some bog gaps in the formula, and a few areas where things could be improved considerably.
The biggest problem with Thermo Fusion is the fact that it doesn’t contain a real, proven appetite suppressant.
As far as we’re concerned, preventing food cravings and combatting over-eating are two of the most basic things that a fat burner needs to do.
During every cut the thing we all struggle with the most is the hunger. Every member of our editorial team has struggled with this in the past, and we’ve all seriously hurt our progress by binge eating or giving in to food cravings.
That’s why we always look for fat burners that have some kind of appetite-suppressing component.
Ideally, we want something that safely and naturally thickens in the stomach to create a feeling of being full – this effect is similar to downing a pint of water with your meal, but we want it to last longer and be more substantial.
We don’t want something that will artificially suppress our appetite or block the absorption of any vital nutrients. Instead we just want something that will make us feel full despite eating significantly smaller meals.
Thermo Fusion doesn’t deliver anything of the kind. There’s no hunger support in this fat burner at all. This marks it out from all of the current market leaders; this is a big omission from Reflex for sure.
In our opinion, leaving out something to control appetite is a big mistake.
Reflex Thermo Fusion Side Effects – Is It Safe?
Generally speaking, Thermo Fusion looks like a safe fat burner.
So long as you follow the manufacturer’s instructions, and assuming you don’t have any pre-existing medical conditions that are relevant, you should be able to use Thermo Fusion without experiencing any adverse effects whatsoever.
However, that isn’t to say that it is equally safe for everybody.
The main risk factor for some users is the caffeine content – Thermo Fusion contains a sizable 160mg of caffeine per daily serving.
That is the equivalent of about 2 shots of espresso.
It may not sound like much, but we assure you that it is, especially if you already drink a lot of tea and coffee.
Thankfully, Reflex Thermo Fusion’s daily serving is split into 4 capsules, so you can space this caffeine dose up into equal servings throughout the day.
But that is still a significant amount of caffeine to consume on top of your existing intake. You need to carefully calculate all of the caffeine you’re currently consuming and work out if it’s safe for you to add in 160mg on top of that.
The side effects of consuming too much caffeine include:
- Shortness of breath
- Elevated heart rate
Consuming large amounts of caffeine over the long-term can significant increase your risk of having a heart attack. It can lead to dependence and chronic insomnia.
Aside from the caffeine though, Reflex Thermo Fusion looks pretty safe to us.
That said, everybody is different. You all need to consider your own unique medical circumstances and do your own research carefully before making any decisions.
It is vital that you remember the following facts while reading our supplement reviews:
- This is not medical advice
- We are not doctors
Please talk to your regular GP before you use any fat burners, even ones we deem safe for most people. You are NOT most people! You need to do your own research properly before using any supplements of any kind. You have your own unique physiology which must be taken into account. If you have any concerns, talk to a proper doctor. If you experience any side effects while using Thermo Fusion, cease use, contact Reflex, and seek medical attention asap.
Reflex Thermo Fusion Review Summary – Is It A Good Fat Burner?
We don’t know why Reflex are so quick to bill this as a kind of jazzed-up chromium supplement.
Thermo Fusion is a solid fat burner.
It is actually a lot more powerful, much more comprehensive, and a lot better value than many products out there claiming to be “hardcore” fat burners!
Each 4 capsule serving provides a large dose of Cayenne Pepper Extract, some Green Tea Extract, and lots of Chromium.
Together, these ingredients will definitely help you during your next cutting phase. They will support insulin action, help you maintain healthy blood glucose levels, accelerate fat metabolism, and put you into a deeper relative caloric deficit.
Thermo Fusion is not without flaws though.
The biggest problem is the fact that it lacks an appetite suppressant.
For us this is actually a bit of a deal breaker; every fat burner should help you avoid over-eating.
The Thermo Fusion formula is far from perfect, but it is a solid formula nonetheless. This fat burner will deliver results.
If you want optimal results and the best possible value for money, then there are better alternatives. That’s clear. But if you want to try Reflex Thermo Fusion we think you will probably see many of the results you’re hoping for.
