Best Fat Burners For 2021: Strongest Thermogenics
Transparent Labs makes two fat burners, one is in a pre workout form and the other is in pill form.
The difference between the two, while they both contain thermogenics, Lean (pre workout form) contains nitric oxide booster and ingredients to help with performance and gains.
The Fat Burner contains a ECA type of a formula, with caffeine, white willow and synephrine, it's nature's formula of ECA (ephedrine, caffeine and aspirin).
And that's not all.
It also has a big dose of Forslean and green tea, followed by tyrosine and theanine.
Here's the pill form ingredient label:
120mg Caffeine Anhydrous, 60mg White Willow, 50mg Cayenne Pepper, 25mg Synephrine HCl
250mg Forslean (Coleus Forskohli), 200mg Green Tea, 150mg 5-HTP, 150mg L-Tyrosine, 120mg L-Theanine
The formula may look simple, but it's generously dosed and it has proven to work ingredients. In fact, this same formula has been a top pick at Transparent Labs for years now without needing to change or tweak it's formula.
Another option is stacking Stim-Free Fat Burner with any pre workout for the ultimate thermogenic stack.
But if you need a thermogenic focused pre workout with pumps and strength support, Lean is your choice.
It's got 6 grams of citrulline, combined with 1.3 grams of taurine and 60mg of norvaline, you'll definitely get some nice volumization going.
It's also got 1.5g grams of beta alanine, 2 grams of BCAA's, 2.5 grams of betaine anhydrous, and a whole lot more.
Lean is one of the best fat burning thermogenic powders available today.

When it comes to non-stimulants, Eliminate combines some of the best fat oxidizing ingredients.
Starting with a punch with a full gram of ALCAR, Eliminate contains a big blend of thermogenics that will force the body to use fat as energy.
Not only will these ingredients loosen up fatty acids and release them into the blood stream, but the carnitine forms in here will help transport these fatty acids for energy to help with ATP production.
The 400mg of green coffee extract is standardized to chlorogenic acid, which is benefical for fatty oxidation.
And there's even more ingredients that will help shuttle fatty acids like the 10mg of Gamma-Butyrobetaine Ethyl Ester, which is in it's patented form Lean GBB.
The combination of forskolin extract, paradoxine and theophylline will help with fat metabolism and enhance energy since Theothylline can block adenosine receptors so you don't feel tired (like caffeine).
Isopropylnorsynpehrine in here will help free up fatty acids as well, which can turn it into energy.
Huge Nutrition clearly have strategized Eliminates formula to maximize fat loss and to force the body to use fat as energy.

Atlas Labs makes DMAA based formulas and they use a fairly straight forward, but strong formulas.
There's two supplements here that can be used as fat burners, one being a fat burner pill based supplement, the other is a pre workout.

Phenta Burn doesn't only have a high dose of DMAA along with other stimulants but it also has 6-Paradol, a super non-stimulant thermogenic.
One of the best and long selling DMAA fat burners is Phenta 1,3.

What will make you really sweat on top of these stimulating ingredients is the big 500mg dose of Dandelion extract. This will boost thermogenesis, even if it was taken with everything else in this formula.
Apart from these ingredients there's vitamins and Chromium, which are all essential for when you're on a strict diet.
To help with cortisol levels, ashwagandha is included at a full 600mg, which will not only decrease stress and anxiety, but it will also maximize testosterone production.

Going beyond just a boatload of caffeine, Napalm has 4 ingredients that will make you sweat, and that's not including the 350mg caffeine.
It doesn't have any downsides or side effects, so it can be used for months without really needing to be cycled.

Chaos Fat Burner is a green tea first formula that uses 300mg caffeine, 300mg dandelion root extract, and a huge dose of Paradoxine.
This the biggest dose of Paradoxine we've seen yet.
Typically, this dosed anywhere from 25-50mg in fat burners.
That's epic and we've only seen it in Chaos.
The 8 ingredients, as you can see, are generously dosed, and it has 60 servings. Meaning it'll last you 60 full days, as each serving contains the full recommended serving.
It also has 30mg GBB and 300mg dandelion extract, both of these are non-stimulant thermogenic but are going to make you sweat way more than any stimulant can. They are also both potent thermogenics.

Condemned Labs have been around for a while now and they are best known for their pre workout Convict, a pre workout powered by 225mg DMHA, 300mg caffeine and more.
You'd assume right that their fat burner is also just as strong.
Arysn contains 300mg caffeine along with 200mg DMHA.
This formula contains the 3 ingredients needed to mimic ECA (ephedra caffeine and aspirin), which is white willow.
White willow is nature's answer to Aspirin as it has salicin, something that reduces pain and increases mobility.
It also uses a green tea extract, in the form of matcha, along with 50mg synephrine, 50mg higenamine, 25mg cayenne, 25mg grapefruit, 5mg vinpocentine along with yohimbine.
Luckily the yohimbine is dosed at a small 3mg.
But what do those ingredients all do together?
They help increase blood flow, pumps along with increasing breathing capacity as higenamine works as a brochodilator.
It's even banned by the World Anti-Doping Agency because it's considered to be a performance enhancer and a brochodilator.
It's also powered by 12.5% Paradoxine, a strong thermogenic that'll make you sweat buckets.
Arysem is a potent DMHA fat burner that'll help with weight loss, energy and appetite suppression.

Alpha Lion has been making premium supplements for a few years now and they haven't slowed down making potent formulas.
There's two versions of fat burners that Alpha Lion makes.
The first is Superhuman Burn, a pre workout focused formula with a thermogenic part to it. For the best bang for your buck, we'd recommend this.
The second is Cheetah Burn, a thermogenic-only formula. It's a bit cheaper as it doesn't have any ergogenic aids aside from stimulants and thermogenics.
Superhuman Burn has a properly dosed formula and the ergogenic includes 4g citrulline and 3.6g beta alanine.
So if you don't want the tingles and could care less about the pumps, then you could skip out on this and get the Cheetah Burn.
However the thermogenic formula is still pretty strong in Superhuman Burn.
It has 225mg caffeine, 225mg theanine, 100mg Infinergy and 100mg Cocoaburtoral.
This is going to lead to some potent energy, that'll be long lasting and you'll feel in the zone for hours at a time.
It also has 500mg Mitoburn, 100mg Advantra Z, and 40mg CaloriBurn GP.
These are potent patented ingredients and they'll make you sweat buckets, it'll suppress appetite and force your body to use fatty acids as energy.
And there's still more with 1g choline, 1g alcar, 1g tyrosine 25mg astragin and 5mg bioperine.
These are potent nootropics, you'll feel long lasting focus along with the strong energy that's already in here.
Superhuman is strong and it doesn't even need banned substances, making it a great choice for those looking for a clean fat burner that doesn't contain anything banned by sports and competitions.
The price difference between Superhuman Burn and Cheetah Burn is around $6.

Herolean is a ultra strong fat burner.
This not only has a big dose of DMHA but it also has DMAA, Eria Jarensis and a whole bunch of thermogenic compounds.
The scientists over at Darkside put this formula intelligently with the perfect dosages and have not overdone it.
Yohimbine is in this formula, and it's dosed a bit high at 10mg, which is something to be aware of if you're prone to the anxiety that may occur from this stimulant.
In Herolean, you're getting 100mg DMAA, it's on the higher side. Anything over 70mg might lead to elevated blood pressure and heart rate but with more pre workouts containing 100mg DMAA, we're starting to think this is becoming the standard for the strongest high-stim formulas.
We find taking something like agmatine or theanine alongside a high stim formula like this subsides the common side effects.
And there's more…
It contains 200mg DMHA, a huge dose considering it also has 300mg caffeine and 250mg eria jarensis.
This is a strong formula. There's still thermogenic ingredients but with just these stimulants, you'll get a strong rush of energy that is both smooth and hard hitting.
Luckily, Herolean is in powder form, you can take less than a full scoop to get closer to the safer range of stimulants.
The other ingredients include the sweat inducing GBB (gamma-butyrobetaine), synephrine, hordenine and yohimbine.
This is something that could be taken at half a serving or even less, and you'd still be sweating buckets with tons of energy to spare.

Thermal Spark has excellent focus, appetite suppression and mood enhancement.
It possibly has the strongest thermogenic effects, it's even comparable to the real ECA stack.
The reason for this is because of it’s stupidly strong appetite suppression.
You won’t feel a slight appetite after taking a scoop, it’s that strong.
Food is hard to chew on after taking Imperial Spark.
It's that strong.
What was once delicious food is now feeling like a chore to chew on.
It's the exact same feels as the OG Craze…
Euphoria, the drive and motivation, and everything else that made Craze what it was is what makes Thermal Spark (and Excelsior) exactly the same.
There's no doubt it will be among the legend of pre workouts when it's inevitably banned.
Thermal Spark is pill version of Excelsior and it has the same ingredients and feels, but without the nitric oxide boosters like citrulline and betaine.
The cost per serving might seem high, but it is similarly priced to what other pre workouts with DMAA might be priced at.
A full serving might still be too strong for most people.
If you try Excelsior, try half a scoop or even less if you want to test out your tolerance, and who knows, you might find half a scoop to be your sweet spot.

Stack these fat burners with supplements that cover your foundation for minerals and vitamins like ZMA (ZMO is a good choice) and creatine for strength / muscle support.
The Stimulants To Look For
There are quite a few stimulants but the main 3 that can power a fat burner's energy blend are:
Here's some info on these stimulants…
Caffeine is a well researched stimulant and known for increasing alertness and energy. It also has potential as a nootropic. Doses of 300mg is proven most effective at burning fat and increasing performance.
DMAA's chemical structure resembles an amphetamine. It can increase focus, mood and fat burning while suppressing appetite Works best when combined with caffeine. Doses of up to 90mg is proven to be completely safe.
DMHA, is known as the milder version of DMAA, it has 80% of DMAA effects and works similarly as it can increase dopamine and noradrenaline levels. Doses of 100mg to 150mg is comparable to 35-50mg DMAA.
What about the other ingredients?
There are a number of ingredients that can help burn fat and boost metabolism but most burners make the mistake of mixing them without giving them much thought.
When properly combined though, these ingredients provide a synergistic effect that help increase your metabolic rate and decrease fat storage without the risk of harmful side effects.
And even if you find a fat burner that have the “best ingredients”, they may have under-dosed ingredients or could be made from low quality sources.
The combinations of supplements are endless, it's especially beneficial to do this with fat burners.
If you're already taking a pre workout you'll need to be careful as fat burners already contain a bunch of stimulants.
Before you consider another supplement, you should check a few things like your diet (calories, macros, proteins, fats, carbs) and then your training (frequency, lifts, etc).
If you're eating more than you burn then you'll struggle losing weight, no matter how hardcore a fat burner may seem.
The advantage with fat burners is that they help suppress appetite, increase energy and thermogenesis.
If you want something without exotic stimulants, check out Eliminate, a fully dosed and disclosed formula with strong thermogenics (use 15% discount code FITFREK).
