Best Thermogenic Pre Workouts


Herolean by Dark Labs

Performance Enhancers
Combines DMHA and DMAA with GBB along with other fat burning ingredients in here
Thermogenic pre workout without creatine or beta alanine
High yohimbine dose may turn off some people

Dark Labs makes some of the most potent pre workouts we've seen to date. 

Herolean is their DMHA and DMAA combo with other thermogenics that make it such a strong pre workout for weight loss. 

It's made for experienced users. 

The combo of DMHA and DMAA is very strong and only a few pre workouts have both of these stimulants.

Herolean packs full dosages of exotic stimulants along with strong thermogenics.

Something like Dark Labs likes doing is combining GBB along with DMHA and DMAA. 

This creates a very heated experience where you'll sweat and have an elevated thermogenenic experience. 

There's also a big dose of eria jarensis at 250mg, which is combined with hordenine.

Having hordenine with stimulants will prolong the effects of the energy and mood.

There's also a fairly big dose of yohimbine, coming to a total of 13mg. 

So if you don't like yohimbine at high dosages, you should try something else because there's still the other stimulants in here. 

L-carnitine l-tartrate is also here to help increase endurance and enhance fat oxidation. 

In total there's 6 thermogenic non-stimulant ingredients in here along with 8 strong stimulants, making Herolean one of the strongest pre workouts for weight loss. 

We can only recommend this if you have experience with pre workouts, or start with a much smaller serving size to assess your tolerance.

Eliminate by Huge Nutrition

Performance Enhancers
Contains the best fat burning compounds
Enhances energy and thermogenesis
Effective fat burner

It's hard to find a fat burner that contains a fully dosed label with research backed ingredients.

Luckily, we have found one of the best fat burners to date. 

Eliminate is by Huge Nutrition, a well reputated company that makes high quality formula's with effective ingredients. 

It's packed with the most effective fat burning ingredients you could ask for.

It has 8 thermogenic ingredients and 4 stimulants. 

All together it packs quite a kick, as it has 1g ALCAR, 400mg green coffee extract, 300mg 5-HTP and more. 

The ALCAR is a source of carnitine and it'll help convert fat into energy, and it also contains GBB, another carnitine based ingredient. 

If this formula just stopped there, with 2 carnitine sources, you would still have a very thermogenic experience as it'll increase sweat and make you feel incredibly heated.

There's a nice small dose of theanine to help make the stimulants hit smoother, at only 100mg. 

The caffeine totals at 250mg, with 50mg coming from di-caffeine malate. 

Caffeine malate is a slow digesting form of caffeine, so this means you'll be getting both slow and fast acting stimulants, for all around energy and focus. 

There's a little dose of yohimbine, at 2mg, which should be fine for most people, but even if you're not a fan of yohimbine, this dose is very minimal, and shouldn't be felt especially seeing how there's 100mg theanine to help ease the anxiety and energy. 

All together, Eliminate makes for an strong fat burner to take before a workout. 

Huge Nutrition also has a non-stimulant fat burner called Exterminate which can be stacked with Eliminate, together you would have every single effective fat burning ingredient in one stack.

Superhuman Burn by Alpha Lion

Performance Enhancers
Has 25 full servings
Best pre workout and fat burner hybrid
Contains strong thermogenic ingredients

Alpha Lion has been at the top of it's game lately and with SuperHuman Burn, they've outdone themselves with this formula. 

SuperHuman Burn has 11 performance enhancing ingredients that'll not only help with fat loss but also with workout performance. 

And that's not including the 4 stimulants in here. 

So in total, Burn is made out of 15 potent ingredients that'll make for an intense experience. 

Starting with a nice 4g dose of citrulline, this ingredient helps with pumps and blood flow. 

The 3.6g beta alanine in here will cause some tingles but if you're already saturated with beta alanine you'll unlikely feel much of it. 

And it's a little more than the 3.2g used in studies. 

This 3.6g is fairly big and it makes SuperHuman Burn a strong contender. 

Taurine is also another ingredient that'll not only help with muscle fullness but also has some research for improving insulin sensitivity, glycogen resynthesis and time to exhaustion. 

The energy blend of stimulants in SuperHuman Burn is quite strong, although it's only made out of 4 stimulants, it's a long lasting combination especially considering some of the non-stimulant energy boosters in here. 

The 1g tyrosine will help produce more of the neurotransmitters that the stimulants release and the 1g of ALCAR will enhance alertness and energy. 

On top of that, there's 225mg theanine which will help prolong the energy boosting effects of the stimulants, allowing you have a Zen-like focus throughout the day. 

Burn wouldn't be a potent thermogenic pre workout without MitoBurn.

This is a trademarked form of L-BAIBA, and it comes with strong metabolic effects that is similar to what you would get from exercising. 

L-BAIBA also has benefits for increasing thermogenesis and fatty acid oxidation. 

The benefits continue with improving glucose tolerance, preventing bone loss and even insulin sensitivity.  

To help optimize the bioavailability of all the ingredients, Burn contains 2 absorption enhancers, Astragin and Bioperine.

Both of these ingredients are patents and they can help increase the uptake of betaine, amino acids, citrulline, CoQ10, and more. 

Burn is a super strong pre workout for weight loss and increasing performance all around.

Lean by Transparent Labs

Performance Enhancers
Improves blood flow and pumps
Helps improve glucose and insulin sensitivity
30 full servings
Citrulline malate is a moderate dose

What if you could have a pre workout with not only thermogenics, but also glucose and thyroid supporting ingredients? 

This is Lean by Transparent Labs, and it has attacks fat from all angles. 

The first thing it has is citrulline, at a moderate dose of 6g, then 2.5g betaine anhydrous for strength enhancement, along with 1.5g beta alanine.

Beta alanine isn't dosed that high, so you probably won't feel the tingles. 

There's also a bit of BCAA's to prevent muscle breakdown, which is a welcome especially if you're under a strict caloric restriction. 

Next up is the 500mg choline bitartrate, a mental enhancing ingredient that will help you on your mind to muscle connection. 

For insulin and glucose support, it has 200mcg chromium, a known mineral that's necessary to supplement with if you're exercising. 

There's also 4 other minerals which are all a must to have when you're trying to maximize your fat loss. 

In total, there's 12 ingredients that'll help with fat loss, in addition to 4 stimulants for direct energy.

The Power is one of the most urgent pre workouts we've experienced. 

So much that it works well for fat burning because it works so well for energy. 

Although the entire blend is under a proprietary blend, it still packs quite a punch. 

It's effects works well for urgent workouts, with lots of aggressiveness. 

It has a slight appetite suppression, you won't think much of food throughout the day. 

And the pumps are great, but that's likely because it contains a good blend of stimulants and ergogenic aids. 

We don't know how much any of the ingredients are dosed but we do know it'll work well.

Enhances performance and pumps
Improves glucose uptake and insulin sensitivity
Strong mix of stimulants for energy and motivation
Has 20 servings of research backed ingredients

Excelsior by Imperial Nutrition

Performance Enhancers
Strong appetite suppression and fat burning
Incredibly strong focus and energy
Contains 40 full servings

Excelsior is unquestionably one of the strongest pre workouts to hit the market over the past few years.

If you've had the opportunity to try Craze by Driven Sports back in 2013 or before, then you would know what I'm talking about. 

Now Excelsior seems like it has a small label of ingredients, nothing but innocent ingredients like caffeine, DMHA, bitter orange, and octopamine right?

Excelsior seems to be much more, and it has a amphetamine-like energy, making it one of the stronger pre workouts by far. 

But because of this, it may have a crash after a few hours of using it. 

And you'll probably feel sick at the thought of eating anything, you'll have to force food into your mouth because of how strong it's appetite suppression is.

We don't recommend this pre workout for everyone, it's best used by users who have experience with high energy and high stim pre workouts. 


Pre Workouts For Weight Loss

Not all pre workouts are created for fat burning. 

While caffeine does have some thermogenesis effects, there are pre workouts that are designed to be used for weight loss. 

The ingredients that are in pre workouts are no secret and they have research to back up their benefits. 

So avoid the thermogenic pre workouts that hide their dosages in blends and only go for fully open formula's. 

Here's what to look for in a thermogenic pre workout…

When To Take Thermogenic Pre Workouts?

Fat burning pre workouts are best taken on an empty stomach for the best results and about 30-60 minutes before a workout. 

This means waiting around 1-2 hours after eating, depending on how heavy of a meal it was.

You could take a pre workout 2 hours before your workout if you're trying to avoid taking stimulants closer to your bed time. 

But we typically suggest taking a pre workout before 3 pm, optimally before 12 pm so it doesn't affect your sleep. 

The best way to make the most out of these types of pre workouts are first thing in the morning, while you're in a fasted state so the stimulants and thermogenics will hit the hardest.

What Are the Optimal Workouts For Thermogenic Pre Workouts?

The best way to take advantage of a fat burning pre workout and get the most out of it is by exercising. 

Simple exercise will help enhance the effects of these thermogenics. 

But the best types for optimal results are the ones with high intensity or high volume or both. 

This can include cardio or weight lifting. 

You can find workouts here.

Most Effective Ingredients for Fat Loss

Stimulants in fat burning pre workouts are only 10% of where the thermogenesis comes from. 

There are useful non-stimulant thermogenics as well as stimulants that can be used in fat burning pre workouts. 

  • Caffeine
Caffeine is a commonly used stimulant, it's a must in pre workouts and fat burners. It can increase awareness and reduce fatigue. It's dosed between 150mg to 500mg, with 300mg being a common dose, anything higher can lead to more jitters and anxiety.

  • DMAA

DMAA is a strong stimulant and it's considered to be banned but it's still used in supplements. It can mimic adrenaline and enhance dopamine production

L-BAIBA can increase metabolism by enhancing fatty acid oxidation and it can also improve glucose tolerance. It's naturally generated during exercise and can be supplemented with for better results. 

  • Higenamine

Higenamine is a mild stimulant that has potential benefits for energy, focus, appetite suppression and fat loss. It's similar to ephedrine and can increase fatty acid oxidation. 

  • Yohimbine

Yohimbine is a alpha-2 antagonism that can create a environment for fat burning in the body. 

  • Citrulline

Citrulline is typically used for it's nitric oxide boosting properties. It can reduce fatigue and improve performance by expanding the blood vessels and increase vasodilation.

The worst thermogenic pre workouts typically have one thing in common, and that's proprietary blends. 

  • ENGN by Evlution Nutrition (underdosed carnitine, prop blend)
  • Vapor X5 by MuscleTech (under dosed thermogenics and choline)
  • Nitrosurge by Jacked Factory (overpriced and underdelivers)
