What Is GNC Pro Performance Thermo Burst Hardcore?
GNC Pro Performance Thermo Burst Hardcore is said to be “powered with 400mg of caffeine and micronized l-carnitine for explosive energy.” It gives you what they call clinically proven endurance and athletic performance to allow you to burn 12 times more calories after your workout than diet and exercise alone.
Is GNC Pro Performance Thermo Burst Hardcore Clinically Proven?
GNC Pro Performance Thermo Burst Hardcore introduces a clinical study that they say proves that their formula, not their main ingredients, is clinically proven to promote powerful weight loss and calorie burning results. They describe 25 subjects spending time on a treadmill 2 times, once with GNC Pro Performance Thermo Burst Hardcore and once without, all leading to 12x the calorie burning.
But then they tell you that it averages out to 278 extra calories. In an hour’s cardio workout, one could easily expect to burn 500 calories. 278 would be a little over 50%, not 1200%. This study will not be found on any other website or through any legitimate source. It has never been recognized by legitimate scientific organizations.
But is GNC Pro Performance Thermo Burst Hardcore more powerful than these misgivings would suggest?

Breakdown Of GNC Pro Performance Thermo Burst Hardcore
GNC Pro Performance Thermo Burst Hardcore has a blend that includes a major fat burner known as black tea. Black tea is rich in caffeine, and it can provide a powerful thermogenic fat burning effect. And it also provides natural antioxidant benefits. But while they provide individual amounts, it may be to their detriment. Any form of caffeine requires at least 400mg. They only have 100mg.
Outside of this, they have a myriad of other ingredients. But not one of them is actually capable of promoting weight loss benefits. The other ingredients in some cases have been tested for weight loss. But ingredients like yerba mate and guarana have effectively been disproven.
