Let's get to the best…

Best Fat Burners For 2021: Strongest Thermogenics


Herolean by Dark Labs

on nutritionalsupplementshop
Performance Enhancher

2g L-Carnitine L-Tartrate, 300mg Olive Leaf Extract, 300mg Rasberry Ketones, 150mg Green Coffee Bean Extract, 25mg GBB, 10mg Black Pepper Extract


300mg Caffeine, 250mg Eria Jarensis, 200mg DMHA, 100mg DMAA, 50mg Synephrine, 50mg Hordenine, 10mg Yohimbine, 3mg Alpha Yohimbine

Enhances energy and perfect as pre workout
Mixes exotic stimulants with strong thermogenics
Mood elevation and appetite suppression
High dose of yohimbine

Update: Herolean seems to be sold out everywhere for now.

The best alternative would be combining Caliente by ASC Supplements and Crack by Dark Labs

When it comes to exotic stimulant formulas, there's one company that is consistent with it.

Dark Labs is one of our favorite companies for formulas that contain DMHA or DMAA, sometimes both!

Herolean in this case has both, a big dose of 200mg DMHA along with 100mg DMAA.

And besides this there's strong thermogenics that'll force fat to be used as energy, as well as being able to improve insulin senstivity.

But the downside to this formula is that it has 13mg of yohimbine.

If you can handle this much yohimbine in addition to DMAA and DMHA then this might be worth a try for you.

But it's strong.

I mean even if you handle the yohimbine, the mix of exotic stimulants is hard hitting.

You should start with half a scoop, or even less, and you'll likely enjoy it.

Vanquish Hardcore by MuscleForce

Performance Enhancher

30mg Paradoxine, 200mcg 3,5-Diiodo-L-Thyronine, 5mg Bioperine


250mg Caffeine, 100mg DMHA, 100mg Eria Jarensis, 100mg B-Pea, 75mg Octopamine, 50mg Theobromine, 30mg Hordenine HCl, 1.5mg Alpha Yohimbine

Works well as pre workout
Reduces appetite for hours
Strong energy and focus

Fat burners that pack a punch with potent energy without making you feel like it's the point of just being unproductive and too strong are hard to find.

But Vanquish Hardcore has done it well.

In fact, this is as strong or even stronger than some pre workouts.

It has strong energy and gives some nice urgent type of feeling like you need to get things done.

This is stronger than most fat burners but it only lasts for a few hours.

It also has appetite suppression that is similar to Thermal Spark, in that it can reduce your cravings for junk food for a good while.

The focus is also quite good although it doesn't have any nootropics, it gives some nice elevation for mental enhancement for a while.

The highlight is definitely the energy as it's one of the strongest for it's stimulation.

Lean by Transparent Labs

on transparentlabs
Performance Enhancher

6g Citrulline Malate, 2.5g Betaine Anhydrous, 2g BCAA's, 1.5g Beta Alanine, 600mg N-Acetyl L-Tyrosine, 500mg Choline Bitartrate, 360mg L-Theanine, 200mcg Chromium, 75mg Guggulsterones, 5mg BioPerine

Decent pumps and nitric oxide boosters
No creatine
Well designed pre workout for fat loss and performance enhancement

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, you'll get some nice muscle fullness 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.

Eliminate by Huge Nutrition

Performance Enhancher
Big 13 ingredient formula
Frees up fatty acids and uses them for energy
Excellent thermogenesis effects

When it comes to thermogenics, 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 Theophylline can block adenosine receptors so you don't feel tired (like caffeine).

Isopropylnorsynephrine 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.

The entire formula makes up 13 ingredients, which is impressive.

If that's not enough and you want to maximize your fat burning, then you can check out their Shredded Stack or their other fat burner, Exterminate

Ripper / Adrenaline by Dark Labs

Adrenaline Ingredients
Ripper Ingredients
Increases energy and mood
Ripper has high yohimbine dose, while Adrenaline has half the dose
Combines exotic stimulants with GBB for ridiculous thermogenesis
High yohimbine dose with DMAA may cause anxiety

There's 2 versions here from Dark Labs.

They are quite similar to each other, but one has DMAA, while the other has DMHA and eria jarensis. 

Honestly I prefer Adrenaline because it has less yohimbine, and it'll be preferred for most people.

Ripper has 15mg of yohimbine.

While I can handle this dose, the majority will find it causes too much anxiety and jitters, especially when combined with DMAA.

Adrenaline will have more of a mood uplift thanks to the addition of 125mg eria jarensis, which is mild compared to DMHA compared to energy, but quite good when it comes to euphoria. 

Both of these formula's have GBB, synephrine and yohimbine. 

But Adrenaline has only 7mg (half the dose) of yohimbine, compared to Ripper's 15mg.

And combining GBB along with either DMHA or DMAA will result in some really nice thermogenic effects.

In simple terms, you'll sweat with either of these, like you've never sweated before. 

You can get these straight from, or Ripper from this store, using discount code FITFREK for both options.

Napalm Thermogenic by 'Merica Labz

Performance Enhancher
Strong stimulant blend
Suppresses appetite and forces fat to be used as energy
Optimizes glucose uptake and helps with blood sugar

When it comes to fat burning pre workouts, ‘Merica Labz has delivered the ultimate choice.

Napalm Thermogenic is one of the best, if not, the best thermogenic pre workout we've seen yet.

It takes the best out of both worlds, from pre workouts and fat burners, and combines it into one product.

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.

On the thermogenic side, it has 500mg MitoBurn, which forces fat to turn into energy, along with 500mg green tea extract, and 100mg Cocoabuterol, and 25mg ProGBB.

This blend is named “Sweat like a lady of the night in church” which is hilariously but yet accurately named.

These 4 ingredients are powerful for fat burning, and they have a wide range of benefits from improving insulin sensitivity, preventing bone loss, to improving mood and suppressing appetite.

The muscle building ingredients are properly dosed, with 6g citrulline, 3.2g beta alanine and 2.5g betaine anhydrous.

The fun part is in the stimulant blend, as there's 350mg caffeine, 300mg eria jarensis and 100mg halostachine.

All in all, Napalm Thermogenic is an intense pre workout for fat burning, energy and mood enhancement.

Demonio Fat Burner by ASC Supplements

Performance Enhancher
Great range of stimulants
Great thermogenesis support
Various forms of caffeine and minimal use of yohimbine
Prop blend

Demonio has a mix of stimulants that makes it one of the longer lasting fat burners on here. 

Combine it with a diet and decent program, you'll be dropping fat much more efficiently. 

While it's formula is potent, it doesn't leave you too overly stimulated, it has just the right amounts of stims. 

It has 3mg of two forms of yohimbine, but still keeps it under a moderate amount. 

Demonio uses some well researched ingredients like Innoslim, which is backed by around 20 studies. 

In fact, all the ingredients are backed by research and will provide all kinds of support from metabolic rate, to insulin sensitivity and more. 

Hordenine is included to help the big mix of stimulants last longer as there's not just caffeine, but also eria jarensis, octopamine, halostachine and beta PEA.

You'll likely be able to stretch this bottle out to 50 servings if you take only one pill, but if that's not enough, then there's just 25 servings. For most people, one pill should be more than enough.

Demonio Fat Burner by ASC Suppleements

Performance Enhancher
Uses effective and scientifically proven ingredients
Increases energy through different stimulants
Big doses of strong thermogenic compounds
Simple stimulant blend
Huge dose of Paradoxine
Increases thermogenesis without relying on stims

If you were looking for the strongest supplements that didn't just use stimulants, you'd go to Apollon Nutrition.

This company has made many reviewers happy with their ultra strong formula's and they don't even need exotic stimulants to satisfy the stim junkies.

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.

But 225mg?

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.

Chaos is an epic formula and without any banned substances, it can be used without worrying about using something with banned substances.


Thermal Spark by Imperial Nutrition

Performance Enhancher
Strongest appetite suppression
Same exact feels as OG Craze
Intense focus, amphetamine feel
Increases energy and motivation
Various stimulants without being overly dependent on caffeine
Unique blend of stims
Prop blends
Can affect sleep quality

Update November/2021: You won't find Thermal Spark anywhere unless it's priced $150 and it's on eBay. You can either get Phenta Plex, or you can pay around $100 for Excelsior or Hydrazine.

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.

If you're in the UK, get it here.

Alternatively you can check out Hydrazine, which is the exact same as Excelsior and Thermal Spark. 

Or alternatively, check it out at Nutricartel.


Fat Burner and Thermogenic Buying Guide

There's no doubt you're struggling to find the best fat burner…

Lucky for you, we've collected the best here.

And I know you've tried a few by now. 

Fat burners that promise big changes, you'll even see advertisements that show a shredded to the bone guy with an overweight guy as the before picture. 

Does it really work that well, you ask?

Probably not.

In fact, most supplements out there are plain garbage. 

And fat burners are one of the worst out there.

I know how you feel though, you've gone through all the Googling you can handle and you want the non-BS, non-biased picks of what really works out there.

So we've picked out the best fat burners, separated them with what they are best for (focus, appetite suppression, euphoria, energy, etc).

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.

You can buy DMHAEria Jarensis and DMAA in bulk powder so you can add them to any pre workout or fat burner (just don't overdo it!). Check them out here.

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.

Natural anabolics like Laxogenin will help enhance muscle growth but make sure you cover your basics first like ZMAprotein and creatine

In the list below, you'll find a range of thermogenics, from ones that don't contain exotic stimulants to the strongest with DMAA and DMHA

If you want something without exotic stimulants, check out Eliminate, a fully dosed and disclosed formula with strong thermogenics (use 15% discount code FITFREK).
