The 5 Best Fat Burning Pre-Workouts In 2024 Our Tested Reviews

Unload is a powerful pre-workout that not only impresses with pumps, energy and focus, but thermogenesis. It is really a solid option for people who want a loaded pre-workout, that will hit hard in just about every category. It starts off with Tyrosine at 3 grams, which is more than twice as much as the dosage in many other brands. This is then followed by NooLVL, an ingredient that can aid with pumps as well as focus. You get a clinical dose of NooLVL, which is nice to see. You then get Alpha GPC and Zynamite. Alpha GPC is great for focus, and Zynamite is good for energy as well as power output. 

A generous dose of Caffeine is also in Unload, because you get 350mg, which is a little above the  industry 300mg standard. You also get RhodioPrime, which is a source of Rhodiola with a high standardization of salidrosides. This is a powerful adaptogen, and very underrated as an ingredient. You also get enXtra, which can help with energy, as well as zum XR. Both can help with energy, and help present a crash. 

AstraGin, has been added to aid with absorption, which is then followed by Rauwolscine and Yohimbine. These two stimulants can really help with energy, and have fat burning properties. The formula is then rounded out by Huperzine A, which can help with Choline levels in the brain.

Unbound Supplements is a new brand on the market that is a retail exclusive brand from the same people who brought you NutraBio. They have some of the most impressive formulas on the market, and seem to always be a good option for any goal. 

Napalm is a powerful fat burning pre-workout from Merica Energy. It is easily the most powerful on this list when it comes to energy. The formula starts off with three proven ingredients that are very common in pre-workouts. You get 6 grams of Citrulline, 3.2 grams of Beta-Alanine, and 2.5g of Betaine Anhydrous. Citrulline can help with pumps and performance, whereas Beta-Alanine can help with endurance. These really make it a pre-workout to us.

Following this you get a powerful nootropic blend which consists of Tyrosine, Caffeine, and Alpha GPC. Tyrosine can help with focus under stressful situations, whereas Alpha GPC can increase Acetylcholine levels in the brain. Certainly a solid focus formula, and the 350mg of Caffeine is certainly on the higher side. Now we some to what really makes this product so powerful, and that is the Eria Jarensis as well as the Halostachine. Both are exotic stimulants that can give you feelings of euphoria as well as energy and focus. These will certainly be felt during your workouts. 

Not we come to what really make this a fat burner. The interestingly named "Sweat-Like-A-Lady-Of-The-Night-In-Church Thermogenic Blend, which starts off with MitoBurn. MitoBurn is a solid fat burning ingredient and you get the clinical dose in here with 500mg. You get the expected Green Coffee Bean and Cocoabuterol, but you also get GBB as ProGBB. GBB will seriously make you sweat, and it is certainly felt in Napalm.

Alpha Lion is a newer company, but with clever marketing and solid products, they have burst onto the scene. With awesome products, cool product names, great flavoring, if you haven't tried Alpha Lion yet, it is worth it.

HWMF is a potent pre-workout supplement from A&S, designed for those who crave intense, hard-hitting energy with a possible bonus of fat-burning effects. Despite its high-stim nature, it doesn’t neglect other critical performance aspects.

The profile kicks off with 6g of Citrulline, which enhances blood flow and delivers better muscle pumps. Next is 2.5g of Betaine Anhydrous, supporting power output and helping you push through tough workouts. Taurine is included to promote hydration and improve blood flow, ensuring sustained performance. Alpha GPC follows at 600mg, providing a high-quality form of choline, which is a precursor to acetylcholine, a neurotransmitter crucial for mental focus and cognitive function.

When it comes to energy, HWMF doesn’t hold back. It contains 325mg of Caffeine Anhydrous, delivering a fast-hitting jolt of energy that surpasses the average 300mg found in many pre-workouts. To sustain this energy, it also includes 75mg of ZumXR, an extended-release form of caffeine that keeps you powered throughout your workout. Additionally, 100mg of CognatiQ enhances brain-derived neurotrophic factor (BDNF) levels, contributing to cognitive health and focus.

For those looking for fat-loss support, HWMF has three heavy-hitting ingredients. Citrus Aurantium Extract provides synephrine, a mild beta-agonist often used in fat burners for its energy-boosting and fat-loss potential. The inclusion of both Alpha Yohimbine and Yohimbe ramps up energy and aids in fat loss. However, these potent stimulants may cause anxiety in some users, so starting with a lower dose is advisable.

Overall, HWMF is a powerful choice for those who want to skip Beta-Alanine and focus on pure, intense energy. Expect a serious boost in energy, noticeable sweating, and a transformation into a true HWMF. This pre-workout is not for the faint of heart but is ideal for anyone ready to take their training to the next level.

Who Makes It?

Axe & Sledge is a blue collar brand making supplements for the hardest workers. Axe & Sledge continues to gain popularity and growth through their formulas and culture that the brand is building. The poster child and founder Seth Feroce represents a lot of what is good about bodybuilding and fitness: grinding and doing the MFing work. 

GHOST Legend All Out could easily be side-by-side our #1 ranked as it is that damn good. GHOST did not have a higher stimulant pre-workout until they launched All Out. This is the most hardcore pre-workout supplement the brand has ever released, but it is 100% compliant and won't cause your heart to beat out of your chest.

The pre-workout contains key ingredients for improved pumps, focus and energy. Citrulline and Citrulline Nitrates as NO3-T are added for improved blood flow. 

Alpha GPC and Tyrosine are added for improved focus, both at higher dosages than we are typically used to seeing (a full 600mg dosage of Alpha GPC and 2,000mg dosage of Tyrosine).

The big thing here for GHOST was the stimulant complex. GHOST elected to go with 400mg of total caffeine from Caffeine Anhydrous and zumXR extended release caffeine. We love the ratio as well. Caffeine Anhydrous is the source of caffeine that hits first, followed by the tapering off impact of zumXR. Users get 300mg from Caffeine Anhydrous and 100mg from zumXR. The combination doesn't make you want to blow your heart out of your chest.

For this particular list, we have to say that it may aid with fat loss due to the Bitter Orange Extract. This is a source of Synephrine. This acts as a mild beta-agonist, and is common in fat burners. 

GHOST adds in Theobromine and Bitter Orange as well for a little extra kick in terms of energy. To round it all out, you get 50mg of AstraGin®, which may help with the absorption of some ingredients. Users will for sure feel the energy burst from GHOST Legend All Out.
