What is Grenade Thermo Detonator?

Grenade Thermo Detonator is a fat burner supplement designed for both men and women. Manufactured by Grenade, a UK-based sports nutrition company, Thermo Detonator claims to aid in weight loss, energy, power output, and focus when used in conjunction with a healthy diet and regular exercise.

Pros and Cons

Before diving into the details, let’s take a quick look at the pros and cons of Grenade Thermo Detonator:


  • Contains green tea, green coffee, and cayenne pepper
  • Strong doses of proven fat burners
  • Well-established company
  • Mostly positive customer reviews


  • Potential side effects

The Ingredients: A Closer Look

To determine the effectiveness of Thermo Detonator, it’s essential to examine the ingredients. Let’s take a closer look at the six key ingredients found in this fat burner:

1. Green Tea (500mg)

Green tea is an effective weight loss aid due to its high concentration of catechins, potent antioxidants that trigger the production of norepinephrine, a fat-burning hormone. The increased presence of norepinephrine means that even while resting, your body is burning through fat. Additionally, green tea contains L-theanine, a compound believed to improve concentration and sleep quality. However, the quantities of L-theanine in Thermo Detonator may not be high enough to make a significant difference.

2. Bitter Orange Extract Powder (420mg)

Bitter orange extract is included for the presence of synephrine, a phytochemical structurally similar to ephedrine, which has been banned from use in dietary supplements. Synephrine raises blood pressure and can cause cardiovascular stress, particularly in overweight individuals who are a large part of Grenade’s target market. Furthermore, the efficacy and safety of bitter orange powder are questionable, as many studies touting synephrine’s metabolism-boosting properties involve mice, and its effects may be more pronounced in rodents than in humans.

3. Caffeine (225mg)

Grenade Thermo Detonator contains a hefty dose of caffeine to boost energy, focus, and metabolism. While studies show that caffeine may promote weight and body fat reduction, the amount in Thermo Detonator could be too high for some individuals. With a total daily caffeine intake of 450mg (two servings per day), users should be cautious of their additional caffeine consumption from other sources.

4. Cayenne (200mg)

Cayenne pepper contains capsaicin, a compound with thermogenic properties that help speed up metabolism and suppress appetite. By raising the body’s core temperature, capsaicin triggers a cooling response, leading to increased calorie burning throughout the day.

5. Phenylalanine (25mg)

Phenylalanine is an essential amino acid thought to promote focus, improve mood, and stimulate whole-body fat oxidation. However, the results of studies involving phenylalanine are tentative and involve small sample sizes. Additionally, the dosage in Thermo Detonator is significantly lower than those used in research, leading to questions about its effectiveness.

6. Green Coffee (10mg)

Green coffee beans contain high concentrations of chlorogenic acids, which help lower glucose levels in the liver. As a result, the body turns to fat stores for energy instead. Although studies show moderate weight loss benefits from green coffee, the 10mg dosage in Thermo Detonator is considerably lower than the amounts used in research.

How to Use Grenade Thermo Detonator

Each serving of Grenade Thermo Detonator consists of two capsules. The manufacturer recommends taking one serving in the morning on an empty stomach and another serving just before lunch or a training session. For first-time users, it is advised to start with one capsule at a time for a week to assess the body’s reaction.

Effectiveness: Does Grenade Thermo Detonator Work?

Grenade Thermo Detonator may boost metabolism and aid in fat burning due to the presence of green tea and cayenne pepper. However, its overall effectiveness is limited by the dosages and other ingredients. Green coffee and phenylalanine, for instance, may be present in quantities too small to make a significant impact. Additionally, the inclusion of bitter orange raises concerns about both its efficacy and safety.

The lack of a proven appetite suppressant and essential vitamins and minerals, such as zinc and vitamin D, are also potential drawbacks. High caffeine content and the risk of blood pressure issues from bitter orange extract may pose safety concerns for some users.

Customer Reviews

Grenade Thermo Detonator reviews on Amazon are mostly positive, with many users reporting impressive weight loss within months of using the product. However, some individuals claim it yielded no benefits, even when used alongside a healthy diet and regular exercise. Others note poor customer service from Grenade.

It appears that Grenade Thermo Detonator may not be suitable for everyone, as some customers complain of health issues after using this weight loss supplement.

Safety: Is Grenade Thermo Detonator Safe to Use?

Though Grenade is a reputable company that manufactures its products in GMP-certified facilities using natural ingredients, there are some safety concerns regarding Thermo Detonator. Pregnant or lactating women, individuals with high blood pressure, and those using prescribed medications should avoid using this product.

The high caffeine content may cause jitters and sleep disturbances for some users, while the presence of synephrine in the bitter orange extract is linked to high blood pressure and heartburn. It is essential to start with a lower dosage to assess tolerance before increasing to the recommended serving size.

Cost and Availability

A box of 100 Grenade Thermo Detonator capsules typically costs £45, with free UK delivery on all orders over £35. Discounts may be available, and bulk purchases can offer additional savings. Unfortunately, there is no money-back guarantee for this product.

Grenade Thermo Detonator Review: Final Thoughts

Grenade Thermo Detonator was a trendsetter in the weight loss supplement market when it first launched over a decade ago. While it does offer some benefits for individuals looking to lose weight and increase lean muscle mass, the product may not be the best choice compared to other fat burner supplements available today.

The main active ingredients are easily obtainable from everyday sources, while other potentially beneficial ingredients, such as green coffee and phenylalanine, are present in insufficient quantities. The lack of appetite suppressants and essential vitamins and minerals, along with the high caffeine content and potential safety concerns from bitter orange extract, may limit the product’s overall effectiveness.

Individuals who are already in good physical shape may not see significant benefits from using Thermo Detonator, while those who are overweight or have other health issues should carefully consider the safety aspects before trying this product.
