Best Fat Burners at GNC

After extensive research, here is my selection of the best fat burners at GNC.

1. Jym SS8

When updating this article in 2021 we noticed that GNC had added the Jym SS8 fat burner to their selection.

This changes everything for the rankings of this article.

Jym SS8 contains many great ingredients in good dosages.

The formula has a hefty caffeine dose of 300mg per day.

Along with 500 mg dose of acetyl-l-carnitine which helps the body use fat cells as fuel.

The formula also has cayenne pepper fruit extract which helps increase the metabolism and calories burned throughout the day.

We also see that it has the green tea leaf extract which is included in most top fat burners.

(HEADS UP! Even though it’s #1 at GNC, doesn’t mean it’s the best one on the market. Click here to jump to the best fat burner on the market.)

Jym SS8 Key features:

Contains proven fat burners in good dosages
Has the acetyl-l-carnitine and cayenne pepper extract
No proprietary blends
Thermogenic effect
High caffeine dose – 300mg (may cause side effects)

If you are limited to buying something at GNC, Jym SS8 is probably the best option in 2021

2. Universal Nutrition Animal CUTS

This supplement may be one of the best fat burners at GNC for guys seeking that totally shredded appearance.

With a massive formulation of 38 ingredients (all of which are hidden in eight different proprietary blends), it aims to hit every aspect of weight loss to really accelerate cutting cycles.

Part of its working processes includes:

Reducing the fat-inducing stress hormone cortisol with ashwagandha.¹
Lowering water retention through the utilization of dandelion root.²
Boosting the metabolism with the inclusion of the stimulant caffeine.³
Improving mood with huperzine to alleviate “comfort eating”.⁴

3. MuscleTech Hydroxycut

These weight loss pills (as opposed to a fat burner powder) concentrate on the process of thermogenesis to elevate fat loss by boosting the metabolism.

Its key ingredients are:

Caffeine—an essential thermogenic fat burner ingredient, although the 270 mg dose may be too intense for some.
Green coffee—boosts the metabolism and can slow down the rate fat is absorbed from food.⁵
Coleus forskohlii—acts both as a thermogenic and creates enzymes which break down fatty acids—although, at a dose of 100mg, it’s less than half what’s required for fat loss.^{6 7 8}
Yohimbe—boosts energy levels and helps with fat burning.⁹

It’s a solid fat-killer with scientifically proven ingredients. But, with just six active compounds, it’s not as potent as the best weight loss products available elsewhere.

4. C4 Ripped

Possibly one of the best fat burners at GNC for guys looking to both drop weight and gain the power of a pre-workout supplement.

For weight loss, this GNC thermogenic product includes:

Caffeine to boost the metabolic rate.
Cayenne pepper which both burns calories and helps with fat oxidation.¹⁰
Coleus forskohlii to boost fatty acid breakdown.

Additionally, to enhance workout performance, it contains:

Tyrosine—increases energy levels, boosts focus, and relieves stress.¹¹
Velvet bean—can enhance protein efficacy and improve recovery times.¹²

Sadly, despite containing some proven ingredients, they’re all hidden in proprietary blends—hence their effectiveness is debatable. The GNC weight loss pills reviews for this supplement report underwhelming results.

5. Cellucor SuperHD

Like the Ripped product above, this is another weight loss supplement from Cellucor. While it remains one of the best fat burners at GNC—yet again, every one of its 11 active ingredients is unquantified.

With a total proprietary blend dose of 521 mg—it’s unlikely that these ingredients will pack enough power to really accelerate weight loss.

This supplement sticks with the usual fat-burning ingredients of yohimbe, caffeine, and green tea—but also includes the novel compound of blue whiting protein hydrolysates.

This fish extract has been shown in some studies to reduce the appetite—although further research is required.¹³

6. Grenade Thermo Detonator

At #5 in this best fat burners at GNC list is a product which claims to declare war on fat. The company behind it says it will increase energy, prevent stimulant crashes, and help to shed unwanted weight.

The truth is, many of its 14 ingredients are proven and effective pound-shedders, including:

Citrus aurantium—a legal alternative to the banned GNC diet pills with ephedrine—it boosts energy levels and burns fat through thermogenesis.¹⁴
Raspberry ketones—can increase the rate of lipolysis (fat breakdown).¹⁵
Green tea extract—elevates fat oxidation, has a thermogenic effect, and stimulates enzymes which breakdown fatty tissue.^{16 17}

Despite its effective ingredients, combining them all together in its “Thermo Detonator Proprietary Blend” means that all doses are hidden. Probably because they’re too weak to be productive.

7. Heat Hardcore For Him

This supplement, made by DAS Labs, could be one of the best fat burners at GNC for guys looking for a male-only supplement.

This product not only requires male physiology but also a high stimulant tolerance—as it contains a massive dose of 275 mg of caffeine. This is likely to cause unwanted GNC fat burner side effects in some guys.

Working to burn fat through thermogenesis, this supplement also includes the metabolism-boosting cayenne and chromium. Furthermore, in accordance with its male-orientated marketing, it contains DIM (diindolylmethane).

This compound is claimed by some to elevate testosterone levels (which can help fat loss), yet recent research shows it has the opposite effect. ¹⁸

8. Burn X12

If you’re looking for a supplement with the minimum of ingredients—this may prove one of the best fat burners at GNC for you.

This is due to the fact that it only includes three active compounds, which are:

Caffeine—to boost energy and raise metabolism.
Cayenne (as Capsimax)—works as both a thermogenic and can prevent carbs from becoming fat.¹⁹
Black pepper—increases the absorption and therefore efficacy of the other two ingredients.²⁰

On the plus side—the formulation is quantified and at effective doses. The downside is that with just three ingredients, its weight-loss powers are severely limited.

9. Platinum Garcinia Plus

This is one of the best fat burners at GNC for guys who want the numerous fat loss properties of garcinia Cambogia.

This Indonesian plant has the ability to:

Burn fat through thermogenesis.²¹
Suppress the appetite—the less you consume the fewer calories you need to expend to lose weight.²²
Inhibit the function of citrate lyase—which can otherwise turn sugar and carbs into fat.²³

Additionally, this supplement includes the proven weight loss ingredient of green coffee extract.

Undoubtedly this supplement has a fat-burning ability with its two proven (and quantified ingredients). But with such a small number of active compounds, it’s not as effective as the most potent available.

10. BPI CLA+ Carnitine

This may be one of the best fat burners at GNC for guys looking for an all-around bodybuilding supplement.

It contains two grams of carnitine. This amino acid has been scientifically proven to drop fat—by improving the utilization of existing fatty acids for energy production.^{24 25}

Additionally, carnitine has the ability to:

Improve brain function to boost focus—enabling you to obtain more from your workouts.²⁶
Lower blood pressure.²⁷
Reduce fatigue and elevate energy—the longer your training sessions the more calories you’ll burn.²⁸

Indeed, it contains quantified and proven ingredients—but with only two active compounds (the other being conjugated linoleic acid) results may be disappointing.

11. XenaDrine Pure

I believe this is one of the best fat burners at GNC for those who suffer from stimulant-induced side effects.

This is because this weight loss supplement is completely stim-free. Instead, it aims to drop the pounds through its inclusion of:

Apple cider vinegar—may reduce the appetite and assist with fat burning.^{29 30}
ALA (alpha-lipoic acid)—while some studies have indicated it elevates weight loss, the results imply this is only to a small degree.³¹
Turmeric—raises the internal temperature of the body which can boost the metabolism to burn calories.³²

Although this supplement does contain compounds that research indicates can reduce weight—there are much more potent ingredients with higher efficacy.

Best Fat Burners on the Market

While the above are the best fat burners at GNC—they’re not the strongest weight loss supplements on the market.

Hence, let me reveal the two most phenomenal fat burners known.

Summary

While the best fat burners at GNC may help to boost fat loss—they’re far from the most powerful on the market.

The majority of them lack sufficient ingredients, are underdosed, or hide away their quantities in dubious proprietary blends.

If you’re looking for the ultimate in weight loss and in the shortest time possible—there is one that stands above the rest.

Forget the best weight loss pills GNC—head over to the official ShredFIERCE website for the most phenomenal results.
