LeanFire™ XT | GNC

Product Information



Whether you’re trying to drop a few pesky pounds from your stomach or get lean and cut for your next figure competition, burning calories for both men and women centers around a few simple concepts. You want clear energy and motivation, mental endurance and focus, and a heightened ability to efficiently melt fat – all in a single formula to maximize results without compromise. That trifecta of benefits is exactly what the three premium blends in LeanFire™ XT deliver, in a scientific symbiosis we call thermovigilance.

Burning fat and sculpting a lean body necessitate increasing thermogenesis – literally producing more body heat. LeanFire™ XT’s Fat Incineration Weight Loss Blend now contains safe and natural Verilean™, a highly bioavailable jitter-free ingredient clinically shown to help you lose weight quickly, reduce BMI, and most importantly, burn more fat relative to muscle during your workouts.

This powerful compound is combined with catechin-rich green tea leaf extract to spark the biological processes that speed metabolic function. Rounding out this blend are L-carnitine, a powerful amino acid, and cayenne pepper, which naturally increases body heat, to help you keep pace with the increased energy expenditure generated by LeanFire™ XT’s cognitive enhancement system.

The ingredients in this system can be found in the Metabolic Mind Matrix, the most critical component of effective thermovigilance. Each LeanFire™ XT capsule contains a precise 150mg dose of caffeine, specifically engineered to stimulate your central nervous system, bolstering concentration and generating laser focus. Nothing works better than caffeine to help suppress appetite and deliver a serious jolt of energy. This increases stamina and endurance, pushing you to run that extra mile or power through that final set.

Caffeine is notorious for generating a post-workout crash, but key ingredients in LeanFire™ XT work specifically to mitigate this problem. To combat the energy downsides synonymous with caffeine, the innovative Metabolic Mind Matrix incorporates L-theanine, helping to eliminate the peaks and valleys of LeanFire XT’s caffeine energy boost. In other words, L-theanine works synergistically with caffeine to deliver a smoother, less jittery energy unlike anything you may have felt before.

The Pure Energy Complex supports the physical and mental boost from the two other LeanFire™ XT blends in several critical ways. Yohimbine, a next-generation stimulant that encourages thermogenesis, works to enhance the effects of the Fat Incineration Weight Loss Blend. Yohimbine helps increase resting energy expenditure, which is vital to achieving the lean physique you crave, while TeaCrine® provides a controlled, stimulant-free lift in energy with premium clarity, improved focus, and virtually no crash.

Nearly every fat burner claims to deliver the same benefits: increase thermogenesis, boost metabolism, and intensify the body’s demand for energy so that stubbornly stored fat can be destroyed. But too many s top there. They load you up with high-stimulant energy and forge completely about the cognitive component – the mind-body connection critical to helping you reach your goals.

LeanFire™ XT is different. It considers the real needs of your body and mind as you work to burn fat and sculpt a new physique, producing clean energy while helping to reduce the nervous anxiety that too often accompanies even t he best en durance boosts. It contains an explosive fat-burning thermogenic complex, unlike anything you’ve probably experienced, but the real magic can be found in the unrivaled Metabolic Mind Matrix.

Thermogenesis, at its core, is about raising your body’s temperature to trigger and accelerate fat oxidation. But as anyone who works out knows, burning fat is more than simply a physical challenge; it’s as much mental as it is physiological. A boost in energy should be paired with improved focus, premium clarity, and peak awareness to be truly useful. And that’s what LeanFire™ XT is all about.

So stop settling for “just another fat burner,” and let LeanFire™ XT show you how the proper dosages of hand-picked, scientifically engineered thermogenic intelligence ingredients can make a difference in your workouts.

Really works!
This is actually something that does in fact work. However, for best results you still need to diet and exercise, but it will curb your appetite and drop pounds way faster than traditional measures!

Makes you jittery
Makes you jittery and you feel light headed and heart races. Only used it for a couple days and now it sits in cabinet.

Not impressed
After reading the reviews here, I was really excited to try XT. Unfortunately it did not deliver on it's promise. Despite taking it as recommended and working out (weight training and aerobic exercise) i saw little, if any, results. It also did not help with my level of alertness, it did not help me power through my workouts.

No thank you
I am returning them to the GNC store. After taking one pill I developed sweats, shakes, jitteriness, nervousness and an unwanted buzz.

Give this a try. But make sure that you take it properly. It shall work for you if you do so.
I have taken it as directed. But taking a pill on an empty stomach properly. You must go four hours without eating in order for it to work properly. Go two hours without eating prior to taking it. Then wait two hours before you eat anything. If a person does something. They shall see results. I have lost seventeen pounds in the last two months simply by taking one per day.

Better than advertised for me
I didn't even take the recommended dosage of two capsules per day. I took one per day before lunch, and then went to work. I work in Operations. It provided me energy, focus, and I dropped 16 lbs in about 2 months. I wasn't hungry, but would still eat about 1800-2000 calories a day. Since I have stopped taking, I have gained 5 lbs back.

Is nausea common using this ?
A shopper on Jul 12, 2018
BEST ANSWER: It contains caffeine so if you are sensitive to that, taking it on an empty stomach or waiting too long before you eat after taking it I have had some nausea. But that can be avoided easily.
