Let’s face it, while being big and strong is fun, a lot of us workout to look good at the beach. We here are not afraid to say we care about our looks and like being lean. It is certainly fun being lean, however being at a lower bodyfat percentage year round is very difficult. It makes sense to simply have a period of the year to focus on building muscle, while focusing the other part of the year on cutting fat and maintaining that built muscle. This is typically seen as “bulking” and “cutting”. Of course when it comes time to cut, lifters look for an edge to help them burn more fat. This is where a pre-workout with ingredients that may help burn fat can be useful. 

For this list, we look at some of our favorite pre-workouts that can be beneficial for fat loss. This is actually a growing category, as many people simply take a thermogenic as a pre-workout. The issue with these is that they typically leave out many ingredients that are more geared to pre-workouts. These include ingredients such as Citrulline, Beta-Alanine, Nitrosigine, etc.. These fat burning based pre-workouts will surely get your energy pumping, make you sweat, help with performance, and maybe even help burn a few more calories than normal.

    #1 Unbound Supplements Unload

    Unbound Supps Unload
    • Rating: 9.0 out of 10
    • Servings: 20
    • Best For: Top Overall Product

    Pros

    • 3g Tyrosine
    • 300mg RhodioPrime
    • Great Energy
    • Strong dose of Yohimbine
    • Interesting Flavors

    Cons

    • Flavors are hit or miss
    • Not widely available

    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. 

    Who Makes It?

    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. 

    What's In It?

    One serving (2 scoops) contains:

    • 3g L-Tyrosine - aids in focus and alertness
    • 1.6g NooLVL – helps with focus
    • 2g Taurine - helps with blood flow and hydration
    • 600mg  Alpha-GPC – nootropic that improves focus
    • 500mg Zynamite - helps with energy and focus
    • 350mg Caffeine Anhydrous - Good for energy
    • 300mg RhodioPrime - adaptogen that helps with energy and more
    • 300mg enXtra - helps with energy
    • 153mg Mucuna Pruriens - source of L-DOPA
    • 139 zum XR - gives long-lasting source of Caffeine
    • 50mg AstraGin® - helps with absorption

    • 2mg Alpha Yohimbine - a crazy strong stim that aids in fat loss and energy production
    • 2mg Yohimbine HCl - a crazy strong stim that aids in fat loss and energy production
    • 200mcg Huperzine - helps with focus

    Bottom Line:

    Unlaod is certainly an easy choice for this, and you can expect to see it on other ranking guides. Not only does it have a loaded profile with impressive dosages of many ingredients, it also may help with fat burning with the additional Yohimbine.  

    #2 Merica Labz Red, White, & Boom Napalm

    • Rating: 8.5 out of 10
    • Servings: 20
    • Best For: Energy

    Pros

    • 500mg MitoBurn
    • 6g L-Citrulline
    • 25mg ProGBB
    • Transparent label
    • 350mg Caffeine
    • Strong Nootropic Blend

    Cons

    • May be too powerful

    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.

    Who Makes It?

    Merica Labz is a a powerful brand that has some very interesting marketing. Not only do they have some powerful formulas, they simply bring some awesome personality to the market. They have gone through a rebrand recently, and still bring the same awesome products. 

    What's In It?

    One serving (one-scoop) contains:

    • 6g L-Citrulline- clinically dosed Citrulline to help move blood into the muscles
    • 3.2g of Beta-Alanine  - Good for endurance
    • 2.5g Betaine Anhydrous - good for power output
    • 1g L-Tyrosine - aids in focus and alertness
    • 350mg Caffeine Anhydrous - Good for energy
    • 300mg Eria Jarensis - helps with energy and euphoria
    • 300mg AlphaSize Alpha-GPC – nootropic that improves focus
    • 100mg Halostachine - helps with energy
    • 500mg MitoBurn™ - new ingredient that may help with fat loss
    • 500mg Green Coffee Extract – helps with healthy blood sugar levels
    • 100mg Cocoabuterol® - a source of Theobromine and other antioxidants
    • 25mg ProGBB - helps promote carnitine levels and makes you sweat
    napalm

    Bottom Line:

    Napalm is a powerful pre-workout that really is not for beginners. Not only are the dosages awesome, the flavor is simply awesome. You will notice a huge amount of sweat while taking Napalm with the ProGBB and MitoBurn, and if you're looking for some help in your fat loss goals, it may help.


    #3 Alpha Lion Super Human Burn

    Superhuman Burn
    • Rating:  9.0 ​​out of 10
    • Servings: 20 Servings
    • Best For: Focus

    Use coupon code INFORMANT to save 15%

    Pros

    • Fully transparent label
    • 375mg Caffeine
    • 2g Tyrosine
    • 10mg Pregnenolone
    • Solid Pumps, Energy, and Focus

    Cons

    • Mixability due to serving size

    SuperHuman Burn is a product from Alpha Lion, and it is really becoming one of our favorite pre-workouts for the year of 2020. Alpha Lion already has multiple variations of SuperHuman pre-workouts, and they have all been impressive to us. 

    SuperHuman Burn is a pre-workout that is meant to help with fat loss, however just looking at the profile, it is much more than that. It starts off with a performance blend which consists of Citrulline, Beta-Alanine, and Taurine. All of them are at solid doses, and they can aid with pumps and endurance. Following this you get the energy blend, which consists of 300mg of total Caffeine, coming from both Caffeine Anhydrous and Infinergy (a time-released Caffeine). So you get energy immediately, and then energy that is released slowly to help prevent a crash. You also get 225mg of Theanine, which can help reduce anxiety or jitters brought on by Caffeine. 

    Next up, we have what really makes this product special. The Fat Burning Matrix starts us off with a new ingredient introduced to the market called MitoBurn™. This ingredient is a source of BAIBA, which is a myokine that your body releases when you workout. This ingredient may be good for oxidizing fat, as well as lowering blood sugar. It is what really separates this product from the rest. Along with this interesting new ingredient, you get you get a Cocoabuterol®, Advantra Z® (a source of Synephrine), and CaloriBurn GP™, which is Grains of Paradise. These are all solid ingredients and they are all dosed well. 

    Finally, this rounds out with a nootropic blend and absorption blend. You get 1 gram of Choline Bitartrate, 1 gram of ALCAR, and 1 gram of Choline Bitartrate. These are 3 ingredients that can help with focus, and all are dosed well. After this we get both AstraGin® and BioPerine® at solid doses, which may aid in absorption.

    Due to the profile and marketing, it is meant to be taken pre-workout. With that said, you could technically take it at any time of the day. This is deserving of its spot on our list easily, and we love seeing Alpha Lion not be afraid to use new interesting ingredients such as MitoBurn™.

    Who Makes It?

    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.

    What's in it?

    One serving (2 scoops) contains:

    • 4g L-Citrulline - Helps with pumps
    • 3.6g of Beta-Alanine  - Good for endurance
    • 1g Taurine - Helps with blood flow and prevents cramping
    • 225mg Caffeine Anhydrous - patented form of Ashwagandha, good for stress levels 
    • 225mg  L-Theanine - amino acid that helps with calming
    • 100mg Infinergy™ - time-released Caffeine
    • 500mg MitoBurn™ - new ingredient that may help with fat loss
    • 100mg Cocoabuterol® - a source of Theobromine and other antioxidants.
    • 40mg CaloriBurn GP™ - a fat burning ingredient with human research to back it
    • 100mg Advantra Z - a beta-agonist which may aid in fat loss
    • 1g Choline Bitartrate - may help with focus
    • 1g Acetyl-L-Carnitine - may help with fat loss and focus
    • 1000mg L-Tyrosine - a precursor to Dopamine that may aid in focus
    • 25mg AstraGin® - helps with absorption
    • 10mg BioPerine - helps with absorption
    alpha lion superhuman

    Bottom Line:

    SuperHuman Burn is a solid fat burning supplement that is is also a pre-workout. With the use of MitoBurn and other fat burning ingredients, the thermogenesis is very noticeable, and it must be experienced. It is a loaded pre-workout, and we highly suggest you try it for yourself.

    #4 Glaxon Specimen YoYo

    specimen yoyo
    • Rating: 8.8 out of 10
    • Servings: 20
    • Best For: Yohimbine

    Use coupon code INFORMANT to save 20%

    Pros

    • Fully Transparent Labe
    • 1g Tyrosine
    • lngredients dosed well
    • 2 forms of Yohimbine
    • Solid dose of Choline
    • NO3-T Nitrates

    Cons

    • Yohimbine may be too powerful

    Specimen YoYo is a powerful pre-workout from Specimen, and really it may even be too strong for us. This is different from their regular Specimen, as the YoYo means it contains Yohimbine HCl and Alpha-Yohimbine. 

    The profile starts off with Beta-Alanine at the clinical 3.2 grams of Beta-Alanine, which is the clinical dose. You also get 2 grams of Betaine Nitrate, which is a powerful dose and will certainly deliver on pumps. Specimen YoYo also contains Astrolyte™, which is a trademarked blend of electrolytes. 

    Of course you also get Taurine and Tyrosine. Taurine helps with hydration, whereas Tyrosine helps with focus under stressful situations. 400mg of Caffeine is certainly a powerful dose, and is certainly on the stronger side. It also pairs well with the 300mg of Cholinace™, which is a blend of 2 separate Choline sources. Certainly going to help with focus there. Theanine is also in here, and this time, it actually makes sense. Theanine can help calm you down, especially with the huge amount of Yohimbine in here. 

    Finally, you get 3mg of Rauwolfia vomitoria extract, as well as 2mg of Yohimbine HCl. These give you powerful energy, and can be a bit much to handle. So if you're not used to Yohimbine, better start on the lower side. 

    The flavors on Specimen are great, and this is certainly one to try out for yourself when you want to build up a sweat, feel energized, boost your performance... this is one to try out for sure!

    Who Makes It?

    Glaxon is a brand that seriously delivers more than they need to with every product. With one of the greatest formulators behind the brand, they are successful in making products perform better than they look on paper, and have made the word "synergy" great again. Expect to see their products on other ranking guides, they deserve it.

    What's In It?

    One serving contains:

    • 3.2g Beta-Alanine – buffers lactic acid which may aid in endurance
    • 2g Betaine Nitrate (NO3-T®) – helps with pumps and performance
    • 1.25 Betaine Anhydrous – helps with power output
    • 1g Astrolyte™ - helps with hydration and performance
    • 1g Taurine - helps with blood flow and hydration
    • ​​1g Tyrosine - aids in focus
    • 400mg SantEnergy™ - helps with focus and inflammation
    • 400mg Caffeine - provides energy
    • 300mg Cholinace™ - choline blend that helps with focus
    • 100mg Theanine - helps with anxiety
    • 60mg Halostachine - helps with energy
    • 3mg Alpha Yohimbine - a crazy strong stim that aids in fat loss and energy production
    • 2mg Yohimbine HCl - a crazy strong stim that aids in fat loss and energy production
    Glaxon Specimen YoYo Label

    Bottom Line:

    Specimen Yoyo is certainly a powerful pre-workout that you should try out for yourself. While some may be turned off with the Yohimbine content, we say give it a go. Worst case scenario you can only handle one scoop and you simply stick with that and save money over time. Great flavors, great product, cool brand... go for it!

    Why Should You Take A Fat Burning Pre-Workout?

    It seems obvious, doesn’t it? You’d take a fat burning pre-workout powder to aid in fat loss aka weight loss. It’s important to note the other benefits you are going to get from a pre-workout. Remember, this is not just a fat burner, but also a pre-workout powder. Yes, if you’re trying to shed fat, then a fat burning pre-workout powder is a solid option, but you will also experience other benefits,

    The best pre-workout fat burner supplements can provide you with:

    • Increased Body TemperatureThermogenic ingredients designed to raise your temperature and, literally, burn fat off your body should be the #1 quality you look for.

    • Increased EnergyThis is a pre-workout at the end of the day. You’re going to get an increase in energy from caffeine and other stimulants used for fat burning purposes. Caffeine is also a good ingredient to aid in fat loss.

    • Prolonged EnduranceNot only are you burning fat off your body through the use of an effective fat burning pre-workout, you should be getting an increase in your endurance. The longer you can go, the more fat you can burn!

    • Strength GainsAs you shed fat, you want to build muscle. Certain ingredients in pre-workouts can aid in strength gains allowing you to achieve just one more rep. That one more rep will help burn more fat and build more muscle.

    • Improved FocusYou should be focused on losing weight, hence the fat burning pre-workout, but an effective fat burning pre-workout will also improve your focus while you’re getting your pump on!

    • Massive PumpsSome, not all, fat burning pre-workouts will aid in the pump. Blood and water flow will increase into your muscles. This makes you look swole, but also helps with the recovery process.

    What to Look For In a Thermogenic Pre-Workout Supplement?

    When you’re specifically looking for pre-workout that helps with weight loss, you will keep your eyes open for different ingredients that contribute to fat loss. You may not be as concerned with focus or pump, but energy and fat burning ingredients are key. The following ingredients are key in these supplements:.

    • Caffeine: this is the king of stims (stimulants). Various forms of caffeine are the most popular ingredients used in pre-workouts. Caffeine stimulates your central nervous system. This speeds up your metabolism and eats away at unwanted fat. Effective dosages are between 150mg-300mg.

    • Yohimbine: this is an effective fat burning supplement found in a lot of great products. Some people have a hard time with this ingredient; it is important you test out your tolerance when trying a pre-workout containing Yohimbine for the first time. Effective dosages are 0.2mg/kg of body weight.

    • Hordenine: yet another effective stimulant. There may not be a lot of studies behind the stim, but supplement companies swear by it, and we can vouch for it too. Not enough evidence to support effective dosages.

    • N-Methyltyramine: add this stimulant to the list of effective fat burning ingredients added to preworkouts! Not enough evidence to support effective dosages.

    • Synephrine: also known as Bitter Orange, Synephrine is an effective fat burning ingredient used in fat burners as well as pre workout powders. Effective dosages are 50mg.

    • Lotus Leaf Extract: this has been used to treat obesity, so you know it is a solid ingredient. Recommended dosage depends on a variety of factors.

    • Rauwolscine: add it to the list of effective stim fat loss ingredients. No evidence to support optimal dosing.

    • Carnitine: this is a non-stim weight loss ingredient. This is used as a stand-alone supplement, or in one of the products mentioned below. Effective dosages are 1g-3g, but in pre-workouts it can be dosed to 500mg.

    • CLA/ALA: fatty acids like Conjugated Linoleic Acid or Alpha Lipoic Acid can be effective non-stimulants against fat. Pre-workouts that focus on fat loss include one or both of these. Recommended dosages vary, but can be 1g.

    • Capsimax (Cayenne Pepper): this is literally what the name is. This is cayenne pepper used to literally melt fat. Many use this to help increase body temperatures.

    Our Pre-Workout Supplement Testing Process

    We examined five different areas of each pre-workout supplement when we compiled our rankings:

    1. Ingredients Profile
    2. Effectiveness
    3. Taste
    4. Mixability
    5. Value

    preworkout powder in bottle

    Ingredients Profile

    When we review each pump activating supplement on their ingredient profile, we look at the active ingredients being used and their dosages.

    Many pre-workout supplements include a variety of beneficial ingredients, but under dose them proving to be non-effective.

    Effectiveness

    Effectiveness is an extension of ingredient profile. If the product uses proven ingredients at clinically suggested dosages, the product should be effective.

    Everyone is different. Everyone takes to different ingredients differently at varying dosages. We have tried and tested each of these products throughout the full duration of their container to ensure these products are effective over their life.

    Taste

    We review taste on two different components. First, how close does the muscle pump supplement taste to the actual name printed on the label. For example, does Blue Raz actually taste like blue raspberry. Second, we review it on overall taste (in our opinion) versus others in the same flavor category.

    Mixability

    Mixability refers to how well does the product mix in 8-12oz of water. The testing process for a pump activating drink we use here is a generic Blender Bottle with the chrome spiral ball. We use regular tap water with no ice.

    Value

    Value is a combination of ingredient profile, effectiveness, taste, mixability and cost. We do not just look at the price tag like a lot of others do. If a product is priced at a premium, we inform you if it is worth the premium price or not based on all the categories. We look at the overall picture of the  pre-workout supplement, and how it compares to other pre-workout supplements on the market.

    Please Note: Many of the “top 10” lists you find online are written by content writers with no in-gym or supplement experience who are paid by the word count to write an article for a website trying to generate money.

    These lists are influenced by brands who pay for placement. These lists contain pump activating supplements that are, for the lack of a better word, garbage.

    The following products on our best of list were used by the author of this article. He used the pump activating supplements through the duration of a full container. Sample packs were not used in determining the rankings of the best pump producing supplements.

    Stop relying on faulty information that is influenced by outside writers and money. This list is the real deal. Here at Fitness Informant, we don’t steer you wrong. Be Informed. Live Fit.
