Grenade Fat Burner Facts

  • Made in the UK and marketed by an award winning British company
  • Available in two sizes; 44 capsules or 100 capsule containers
  • This supplement contains high levels of stimulants

Whether you work out at the gym, are a bodybuilding fanatic or are simply looking for some support in order to lose a few pounds, a fat burner can seem appealing. Fat burners contain stimulants that increase the metabolism and the rate at which you burn off excess weight. As an added extra, fat burners also reduce the appetite and perk up your energy levels.

Grenade Thermo Detonator Fat Burner contains high levels of caffeine and green tea extract in doses that you will probably notice and will give you this speedy energy enhancing effect. Green tea is rich in antioxidants and can promote fat burning by thermogenesis as well as providing some real health benefits.

Grenade should have stopped at that point because more worryingly, Grenade Thermo Detonator Fat Burner contains bitter orange powder that is well known for side effects and has a proven effect of increasing your heart rate and blood pressure.

This makes it unsuitable at first glance for people who may have health issues but has also been linked with causing strokes and heart attacks in people who are young, fit, and athletic.

Bitter orange extract contains a chemical called synephrine, which is used as a replacement to ephedrine – a chemical that was once the mainstay of fat burning pills. When ephedrine was made illegal in 2003 because of its proven links with causing heart attacks and strokes, the diet pill industry looked to synephrine as a replacement.

Synephrine is not any safer although it is legal and causes many of the same health issues. See our Watchdog video about the dangers of synephrine.

How to Use Grenade Thermo Detonator Fat Burner

To use Grenade Thermo Detonator Fat Burner, take 2 capsules on an empty stomach upon waking with water. Take 2 capsules 30 minutes prior to lunch with water.

To assess tolerance consume 1 capsule twice per day for the first 7 days. For an explosive workout, take 2 capsules prior to training.

Drink at least 8 glasses of water per day. DO NOT exceed 4 capsules per day.

Grenade is a British company who are based in Coventry. It is run by husband and wife team Alan and Juliet Barrett who have just picked up an award at the Midlands Entrepreneur of the Year show.

Grenade is a rapidly expanding company who are reaching a global market. They are a British success story and very reputable.

Grenade will not trick you into any scams such as auto billing. They sell a range of products including Black Ops – an fat burner which we covered in a previous review, as well as amino acids supplements such as Defend, Engage – a Creatine supplement and other various products including snack bars like Reload Protein Flapjacks and similar.

Grenade Thermo Detonator Concerns:

  • Does taking stimulants really help you lose weight?
  • This supplement may cause unpleasant potentially dangerous side effects
  • Isn’t packaging a diet pill in a plastic hand grenade a bit embarrassing?

What Does Grenade Thermo Detonator Claim To Do?

According to the advertising;

Grenade is a weight-management product that combines perfectly with your high-protein, calorie controlled diet and exercise routine to “Declare War on Fat”

The advertising explains the green tea content too:

With a massive 500mg of Green Tea extract per serving, Grenade packs just about the biggest punch in the industry with regard to this proven ingredient.

Carefully processed green tea extracts contain specific levels of molecules called “Catechins” – these are chemical polyphenols that have been shown to have positive effects on body weight and measurements and to have strong antioxidant and health-supportive properties

Not so impressive is this comment about the bitter orange extract!

The advertising states that;

Grenade delivers the highest Bitter Orange Powder levels of any major weight management product on the market!

“Why only use a sprinkling of effective ingredients, when you can deliver the goods with a proper dose?

…there is an easy answer to that statement. It is because Bitter Orange powder is dangerous!

However the advertising goes on to say;

A full 420mg of Bitter Orange – has been deployed. Most people who’ve been around the block know that this stuff packs a punch!

Yes, it can pack a punch – and it sounds good if you put it like that. The truth is that a punch is not quite as sexy if it increases your risk of a stroke or heart attack!

So What Is Grenade Thermo Detonator and What Are The Ingredients For Grenade Thermo Detonator?

Grenade fat burner is a diet pill that may help increase the speed of your metabolism and help you burn off fat.

Each serving is two capsules and quoted contents are per serving of 2 capsules.

  • Green Tea (500mg): This has proven health benefits and the antioxidants (ECGC and polyphenols) found to have anti obesity and fat burning properties because of the effects upon the metabolism.
    According to some clinical investigation, Green tea combined with resistance training may lead to a decrease in body fat.
  • Bitter Orange Powder (420mg): Bitter Orange also known as Citrus Aurantium contains synephrine, which has an effect upon adrenaline and can put your body into a stressed fight or flight response.
    This response raises the heart rate and increases blood pressure, which is potentially dangerous. This ingredient can decrease the appetite by making you feel too stressed to eat but the danger is that it is linked to heart attacks and strokes. There have been cases of otherwise young fit and healthy people suffering heart attacks following taking bitter orange supplements.

  • Caffeine (225mg): Most diet supplements contain caffeine and it is ideal for giving you a quick energy boost. It can increase the speed of the metabolism and help fat burning but the effects are often short lived as you become accustomed to use. When used in combination with green tea it may enhance the fat burning effect. A cup of instant coffee contains around 100mg of caffeine so this serving size is the equivalent of just over two cups
  • Cayenne (200mg): When taken in sufficient quantities, some research has indicated that high levels of capsaicoinds, the compound that causes the fiery sensation of cayenne, increases the metabolism and promotes fat burning. One clinical test carried out in Thailand found that after eating 5g of chilli peppers the metabolism was increased for 30 minutes after ingestion.
  • Phenylalanine (25mg): Amino acid found in protein including eggs, meat, fish and milk.
    The body may use L Phenylalanine to make chemical messengers but it is unclear how it works or even if it does. Can increase blood pressure.
    Source: WebMD resource
  • Green Coffee (10mg): Much touted ingredient after exposure on the Dr Oz show that can promote some weight loss. Research indicates that weight loss is minimal.
    Scientists report that,

    More rigorous trials are needed to assess the usefulness of Green coffee as a weight loss tool


So What Does All This Mean?

You will probably notice the effects of Grenade Fat Burner. It contains high levels of stimulants that may see you bouncing off the walls when you first try it. The product information advises that you build up gradually to taking the full dose and therein lies one problem.

The body can quickly become accustomed to taking caffeine so you may find that this aspect of the energy boosting and weight loss wears off.

However, this does not take away the fact that bitter orange extract and Phenylanine affects your adrenaline levels and puts your body into stress mode. This is not healthy and can put strain upon the heart and blood pressure. You may notice a decrease in appetite as a result. You may notice side effects if you are sensitive.

According to the Grenade information, Bitter orange has been proven safe in a recent scientific journal but most clinical evidence suggests otherwise. Until there is as much evidence that proves this ingredient is safe as there is that proves it is dangerous, we cannot believe it.

Does Grenade Thermo Detonator Have Any Side Effects?

Yes, it may cause side effects for some users.

One customer reported;

Made me more hungry than usual! Extremely thirsty with a sore mouth and throat. Stopped taking them for a week thinking I was coming down with something. When I started taking them again all the symptoms returned!

Sickness and nausea is also an issue for many;

I’ve been on it for a week and all it’s done is make me feel sick as hell to the point where I can’t face food and last night after training I passed out then threw up

Water seems to help reduce this problem, according to some customers. One reported:

Did nothing but give me heartburn which goes when you drink lots of water.

Many customers have likened the effect to drinking too much coffee,

only took one in the morning and one at lunch and it just feel like you have drank lots of coffee, difficult to concentrate at work and to warn you the SWEATS are awful.

This same customer went on to say;

I found I got the caffeine crash at 4pm.

Potential side effects may include:

  • Headaches
  • Nausea
  • Vomiting
  • Jitteriness
  • Sweating
  • Energy crash
  • Insomnia
  • Increased heart rate
  • Palpitations
  • Increased risk of heart attack
  • Elevated blood pressure
  • Increased risk of stroke

Caution: Avoid if you are pregnant or breast-feeding. Grenade advises that you should avoid if you suffer from high blood pressure or any kind of medical condition related to the heart or thyroid.
Seek the advice of your doctor if you \are diabetic or are taking medication for a medical condition due to the risk of drug interactions. Do not take if you suffer from glaucoma or depression
If you are not used to caffeine products such as coffee, you are advised to proceed very slowly with this supplement.

Any Grenade Thermo Detonator Reviews From Customers?

There are plenty of reviews and there is a range of opinion from genuine customers.

Some people like this supplement.

It does what it says it’ll do and it really does give you that extra boost during your work out!


These are a good training aid to help lose some weight, however you have to train with them you can’t take them and sit on your arse and expect results

Are typical positive comments.

Many customers have struggled to open the grenade shaped container:

Be careful when opening the tub, I bet first time you open it the tabs go everywhere!

Many customers mention the importance of drinking water:

Great product been using it for a month now and can see the difference already. One thing is you must drink plenty of water ….would recommend this product thumbs up

Not everyone is as pleased;

Will not work on its own. There is no magic in weight reduction. Haven’t found yet an alternative to calorie reduction and exercise.

Terrible product. Followed instructions to the letter, all I was left with was a racing heart and the sweats. Wouldn’t advise taking this, in my opinion, they are dangerous.

So Does Grenade Thermo Detonator Work?

It depends on what you want it to do! It will undoubtedly have a stimulant effect but whether this will equate to weight loss is not quite as clear-cut. However, caffeine combined with green tea does have some evidence that it helps fat oxidation.

One clinical test found that Green tea has thermogenic properties and promotes fat oxidation beyond that explained by its caffeine content.


Caffeine also has an effect upon fat burning in its own right. It increases the metabolism so helps you burn off fat at a faster rate than normal.

The problem is that the body soon becomes accustomed to the effects and although you may experience initial weight loss this effect usually slows down.

After all plenty of very overweight people drink coffee all day, so caffeine obviously does not work for everyone!

Grenade claim that their bitter orange extract is safe and that the health concerns about this ingredient have been exaggerated. The trouble is that they appear to have based this viewpoint on a “recent scientific journal” but have failed to provide any evidence.

Bitter orange is listed as a potentially dangerous supplement ingredient with very real side effects around blood pressure and heart. There is no evidence that it increases weight loss.

Where Can I Buy Grenade Thermo Detonator?

You can buy Grenade Thermo Detonator Fat Burner direct from the Grenade website.

If you live outside the UK, you need to contact Grenade to find your local stockist although more likely this will be international shipping costs. We can see obvious problems in posting a copy of a hand grenade to a war zone for example.

Watchdog Verdict

With its novelty packaging, and army themed advertising style, Grenade Thermo Detonator Fat Burner is certainly memorable! Some consumers have felt that it has helped with their weight loss and work out regimes but not everyone is as pleased because there is a high level of negative feedback mainly around the various side effects.

Grenade Thermo Detonator Fat Burner is expensive which will not suit everyone, even if you do get a free tee shirt! However, our concerns are mainly around the ingredients and in particular the bitter orange content.

Despite Grenade’s assurances that this ingredient is safe, we feel that you should err on the side of caution. There is a lot of evidence that shows that bitter orange is linked with potentially dangerous side effects and is it really worth taking a risk with your health in order to increase your fitness?

We don’t think it is and mainly for this reason, we have no other choice but to reject Grenade Thermogenic Fat Burner.
