Grenade Thermo Detonator Review

Alan and Juliet Barratt wanted the world to have an iconic weight loss product, which is why they created their explosive (like a grenade!) formula that is Grenade Thermo Detonator. It combines all-natural plant compounds, amino acids, and a boatload-and-a-half of caffeine into convenient capsules that they claim will light up the fat even better than all the other similar products on the market. 

Let’s see if they’re right in this review of Grenade Thermo Detonator!

About Grenade Thermo Detonator

Grenade Thermo Detonator combines energizing compounds, potent antioxidants, and caffeine along with more caffeine in a formula meant to ignite a blazing inferno of fat in you. It does this with the thermogenic effects of stimulants and other compounds, along with helping you have more energy to burn more energy. 

No, it isn’t for those sensitive to caffeine or other stimulants, though for those who aren’t, get ready to flit around like a bumblebee as you watch the pounds melt away.

Grenade Thermo Detonator Benefits

Increases Energy

When you combine energizing amino acids, herbs containing synephrine (similar to ephedrine), and enough caffeine to make a horse dance like a dragonfly, you get…increased energy! This helps you lose fat both by revving up your metabolism as well as giving you the motivation to hit the gym, running trails, pool, or wherever you go when you can’t sleep and feel too jittery to do anything other than work out. 

Grenade Thermo Detonator Supplement

Helps You Meet Your Lean Physique Goals

With its energizing and metabolism-boosting thermogenic compounds, Thermo Detonator is designed not just to increase your body’s fat burn, but to get you moving, which helps you build more muscle. 

In fact, since bitter orange is a good source of synephrine—a stimulant that’s similar to the recently banned ephedra—and phenylalanine provides energy from within, you’ll have multiple sources of get-up-and-go compounds to have you working out like a fiend. 

Increases Focus

Caffeine, more caffeine, and other stimulants don’t just get you up and moving; they get you mentally locked into whatever it is you’re doing, be it working out or just reading a book if you’ve got the patience despite all the stimulants in you. 

This makes the product an excellent addition to long study sessions, drives, or any other tasks that require endless concentration and focus. 

Reduces Junk Food Cravings

If you’re interested in losing body fat, pills alone aren’t the answer since you also need to eat right, drink plenty of fluids, get enough sleep, etc. But along with cranking up your metabolism to complement your diet of lean proteins, healthy fats, and plenty of fresh, multi-colored fruits and veggies, Thermo Detonator can help you meet your dietary goals by reducing your cravings for sugary, salty, starchy processed foods. 

Remember that your body craves the fuel it’s running on, which means as you light up the fat stores, sugar, in particular, becomes less appealing in favor of healthy fats, and losing body fat also boosts your body’s production of androgens while lowering stress-induced, sugar-loving cortisol. This makes eating right easier and more attractive than when stress hormones and the cravings for junk they cause are in control. 

Grenade Thermo Detonator Ingredients

As we mentioned, Grenade Thermo Detonator is heavy on caffeine. In addition to that, it also includes green tea, bitter orange powder, cayenne, phenylalanine, and green coffee. Below we will take a more thorough look at each of these ingredients and their benefits.

Grenade Thermo Detonator Supplement Facts

Green Tea 500 mg

It’s in all the other fat burners on the market, so why not include it in this one? It has potent antioxidants, can help balance your stress hormones, and contains soothing, mood-elevating L-theanine to balance out all the caffeine in Thermo Detonator—including the caffeine in green tea.

Bitter Orange Powder 420 mg

Just in case you miss getting wired to the teeth on the speed-like ephedrine, which used to be legal and readily available in gyms everywhere, you can still get similar effects with bitter orange extract. 

That’s because it contains a compound similar to ephedra—synephrine—which, while not as intense, still gives you a strong boost of clean energy. 

And yes, like ephedrine, use enough, and your scalp will tingle!

Caffeine 225 mg

It’s the most readily available legal stimulant in the world, and it has thermogenic properties that can boost your metabolism like gasoline on a campfire…well, maybe not quite that drastically, but we’re having fun with the analogies here…so why not?  

It can also help you avoid sleep, keep your blood pressure in the stratosphere, and can put the L-theanine and other focus-friendly compounds in Grenade Thermo Detonator to good use. Remember, not only does the product contain 225 mg of raw caffeine, but it also contains green tea and green coffee, both of which add yet more caffeine. So that altogether means there’s enough in the product to cause a frenetic state of mind. Keep in mind this amount of caffeine is high, even for a fat burner. So if you’re sensitive to caffeine, you may want to consider an option that has less, such as Skald with 110mg or, if you really want to avoid it altogether, Burn Lab Pro contains no caffeine.

Cayenne 200 mg

If you love the heat, you’re in luck since capsaicin—the stuff in hot peppers that makes ‘em hot—has thermogenic properties that can rev up your metabolism and help control your appetite. 

Of course, if you don’t love the heat, you’ll be happy to know that you can get the same effects without hitting the taste buds on the way down by popping it in a capsule. That way, you get the warming effects inside without the scalding effects on your tongue, though this doesn’t mean it won’t cause a burning ring of fire on the way out. Probably nothing to worry about, though some may be sensitive…

Phenylalanine 25 mg

This essential amino acid is necessary for the production of many hormones, especially epinephrine and norepinephrine, which are energizing “fight-or-flight” hormones. It also boosts dopamine, which in addition to being your “reward” hormone that helps you feel good, has an influential relationship with testosterone—a hormone known to help you burn fat. 

Together this means the phenylalanine in Thermo Detonator both energizes you to work out more and boosts hormones that help you burn fat, recover more quickly, and energize you. 

Green Coffee 10 mg

Much like green tea, it’s almost like a requirement that every fat burner on the market includes a sharp dose of green coffee extract. 

And, like everyone else, Grenade adds its obligatory ration of this Dr. Oz special to their formula (yaaawwn). But there is evidence that much like coffee that’s been roasted, green coffee may help you burn fat, just that it hasn’t been roasted. 

It is green, though, so there’s that….

Does Grenade Thermo Detonator Work?

Yes, Thermo Detonator will accelerate your body’s ability to burn fat, though as with any fat burner, you need to do your part: get enough exercise (which loads of caffeine will help you do), eat a balanced whole food diet that’s high in protein, complex carbs, and good fats, drink plenty of water, lower your stress, and be sure to get enough quality sleep each night. Do all that, pop a few pills, and shazam! Away go the pounds. 

Well, maybe not quite that easy since popping a couple of these critters will likely eliminate your ability to get enough sleep, and there’s that whole thing about caffeine increasing your body’s production of stress hormones, but other than that, it works!

Who Is Grenade Thermo Detonator Best For?

Anyone 18-or-over who’s not pregnant, nursing, or sensitive to caffeine can benefit from this product. This includes college students cramming for finals, truck drivers, and anyone else who needs sharp concentration and mental energy.

For athletes, the product can boost energy and performance, although it’s advised that you check with your sport’s governing bodies for legality since the synephrine in bitter orange has been banned in some sports.

Claims vs. Reality

They claim their product is explosive like a grenade, and since it’s got about as much caffeine as a grenade has gunpowder, we believe them. No, it isn’t an end-all solution that will light up the fat stores without some effort from you, though it is a beneficial complement to a good diet, plenty of exercise, and sleep like you can’t get after popping caffeine pills. 

Is Grenade Thermo Detonator Safe?

Okay, do we really need to remind you of all caffeine’s safety and side effects, such as that it raises blood pressure, causes insomnia, makes you jittery and causes dads to be short-tempered with their cute little children? 

The product also shouldn’t be used by pregnant or nursing women, or anyone even thinking of taking more than 2-capsules in a day. Doing so will not only cause you to run around chewing down trees like a beaver, it will cause your heart rate and blood pressure to soar, your kidneys to feel like they’re going to explode, and can cause irregular heartbeat, dizziness, nausea, vomiting, and more.  

And finally, if you have high blood pressure, check with your doctor first—or better yet, work on lowering your blood pressure by not using a stimulant-laden product such as this—and of course, if you’re on any medications, always consult with your doctor before using this or any other supplement.

Where To Buy Grenade Thermo Detonator

Thermo Detonator sells for around $40 for 100-capsules, or about 50-days-worth if you’re a fiend. That’s a LOT more caffeine than Starbucks will sell you for the cost, so there is some good value here, and Starbucks doesn’t typically add bitter orange or green tea to your mega-vanilla-super-foo-foo-tofu-latte-special, so there is some decent bang-for-your-buck when it comes down to it. 

If you think you’re up for the explosive fat burn Grenade claims Thermo Detonator will deliver, it can be purchased through many retailers, both online and brick-and-mortar, including GNC, Amazon,, and The Vitamin Shoppe. Strangely, it isn’t available on Grenade’s site in the US, though many of their other quality workout products are.
