GNC Pro Performance Thermo Burst Hardcore Review

gnc thermoburst hardcore

GNC Pro Performance Thermo Burst Hardcore is described as the powerful and effective way to change your own life! When you use GNC Pro Performance Thermo Burst Hardcore, supposedly you will be able to get a clinically proven, thermogenic blend that improves endurance and athletic performance.

This blend is designed to improve physical activity and energy with 400mg caffeine and l-carnitine.

Additionally, manufacturers make references to a study conducted on 25 subjects, exercised 2 separate times: once with GNC Pro Performance Thermo Burst Hardcore and once without.

But will it work?

GNC Pro Performance Thermo Burst Hardcore Ingredients

GNC Pro Performance Thermo Burst Hardcore ingredients includes the following ingredients:

gnc thermoburst hardcore supplement factsGinger root extract

Yerba mate extract: This South American stimulant interacts with the central nervous system to give you a temporary boost in energy so you can burn more fat.

Guarana seed extract: A plant-source of caffeine, Guarana offers more caffeine per serving than a cup of coffee. It also increases energy levels and stimulates thermogenesis.

Capsimax capsicum extract: Extracted from spicy peppers, Capsimax is a thermogenic ingredient that increases the body’s core temperature for a more efficient calorie burn.

Black tea leaves extract: More fermented than green tea, black tea contains stimulating compounds (such as caffeine) to increase energy levels.

Micronized L-carnitine: This essential nutrient acts as a transport for fats and fatty acids, moving them to the mitochondria of cells where they are broken down into energy.

Dill weed extract: Dill weed is related to the parsely family and is a great source of vitamins, minerals, and flavnoids. It has anti-inflammatory and antiviral propreties, and studies have shown that it can even lower cholesterol.

Grape seed extract: There is strong evidence to suggest that grape seed extract may be able to improve cardiovascular healthy by reducing swelling and eliminating free radicals.

The Validity Of The Study

Manufacturers conducted one supposed study on this formula, which they reference frequently, but the study has never been published, and it’s extremely biased due to the fact that it was conducted by GNC.

There are multiple studies that have shown that ingredients like black tea promote weight loss. However, other ingredients in GNC Pro Performance Thermo Burst Hardcore have been proven not to promote weight loss results.

Risks and Side Effects

With so many stimulants found inside the formula, it’s only natural to expect a few negative side effects along the way:

• Dizziness
• Nausea
• Fainting
• Vomiting
• Insomnia
• Jitters

If you are sensitive to stimulants, you’ll want to avoid purchasing this product.


This dietary supplement is meant to be taken three times a day. Many consumers found better results when taken one hour before intensive exercise – and some suggest that 2 pills is enough to give you results while keeping the side effects to a minimum.

You’ll want to avoid consuming any caffeine from other sources as well, including coffee, tea, and soda. Additionally, it’s important that you stay hydrated throughout the day and drink plenty of water.

Consumers who love Thermo Burst tend to take it on a long-term basis (1-3 years) rather than for a few short weeks. I’m honestly surprised at seeing such die-hard fans clinging to the formula.

Product Price and Guarantee

Interestingly enough, GNC is no longer selling this formula, so if you want to buy this thermogenic fat burner, you’ll have to turn to second party distributors. I managed to shop around and find Thermoburst hardcore for about $24.99 on and for $24.47 on

Currently there is no money-back guarantee associated with this product.

The Taste

Even though Thermo Burst is designed to be swallowed whole (rather than chewed), many consumers pointed out that the supplement tasted a lot like ginger. If you’re not a fan of the ginger flavor, you probably will have a hard time choking it down each day.


GNC Pro Performance Thermo Burst Hardcore claims to help you to see the best possible weight loss results, and judging from the consumer reviews, you’ll definitely get a great boost in energy – which is a definite plus when it comes to pushing through an intense cardio workout.

While simply increasing energy levels may be just what you need to motivate yourself to workout more and lose weight, GNC Pro Performance is not very well balanced when it comes to reducing appetite or detoxifying the body of harmful toxins. If you want a more well-balanced approach, then you might want to try leading fat burner and appetite suppressant Apidextra instead. You can read more about Apidextra here at this in-depth review.
