Bottom Line

Update: Herolean is back in stock, but probably not for long.

You’ve probably never seen a fat burner with this potent of a formula before.

It contains typical thermogenic stimulants with DMAA and DMHA on top of the ingredients. 

It combines these hardcore stimulants with GBB, a sweat inducing non-stimulant and it is strong to say the least.

However if you’re not a fan of yohimbine, then Herolean may not be for you since it has a big 10mg yohimbine dose along with 2mg alpha-yohimbine.

Ready to sweat?

Ready or not, Herolean is one of the most potent formulas for fat burning.

It will forcibly kick your behind with it’s potent thermogenic formula. 

It’s strong. 

The combination of ingredients here are never before used together, like GBB along with DMAA and DMHA. 

Dark Labs is known to deliver hardcore formulas, this is on the same level as their limited edition Crack. 

Although Crack Reloaded is another pre workout that packs a punch as well. 

So if you’re in for such a fat burner / pre workout hybrid, then let's dig into it…

In case you can't find Herolean in stock:

The best alternative would be combining Caliente by ASC Supplements and Crack by Dark Labs or any pre workout. 

What To Expect

Herolean is a strong thermogenic formula that’s similar to the pre workouts that Dark Labs makes.

The combination of the thermogenic compounds and exotic stimulants is unique and it’s a rare one.

But the downside is the yohimbine dosage.

It’s a big dose of 10mg along with 3mg alpha yohimbine.

If you can handle the yohimbine, then this might be one for you to try.

The entire formula is going to be hard to use at full dose, and most people will enjoy it at half or less a scoop because of the potency.

Flame is a pre workout formula with 500mg eria jarensis, 300mg DMHA and more...


The entire formula here is made out of stimulants, nearly. 

The 300mg caffeine along with 200mg DMHA, 100mg DMAA and 25mg GBB is a never before seen combination of ingredients. 

DMAA along with GBB will make you sweat, and the yohimbine on top will just make you drench and your fat will cry away. 

It may be hard to workout on this because of the level of jitters and energy that this provides but taking this for a simple cardio session may just be perfect. 

However, taking this and not moving alone will be hard.

Herolean is strong and we don’t recommend it for beginners. 

Even advanced users will enjoy half a serving, which gets you 100mg DMHA, along with 50mg DMAA and more.


L-Carnitine L-Tartrate (2g)

This is a common ingredient to see in fat burners, at least some form of carnitine. 

L-Carnitine L-tartrate can enhance recovery by reducing the muscle damage done by resistance training while improving insulin sensitivity. [1]

It can also help fatty acid metabolism and increase focus.

It works like a transporter, moving free fatty acids to the mitochondria in the cell, converting it to energy. 

Which makes it important to have enough l-carnitine to increase fatty acid oxidation. 

While caffeine and other stimulants can help free up fatty acids, without sufficient carnitine, they will unlikely be used to create ATP (adenosine triphosphate). 

There’s a few different forms of carnitine, but this is faster acting and has better absorption. [2]

Dark Labs has gone with the clinical dose here of 2g, which is the same used in studies.

Olive Leaf Extract (300mg)

This extract is extracted from Olea europaea tree leaves and has several benefits including being anti-inflammatory and it’s a strong antioxidant. [34]

Olive leaf has research showing that it has a high concentration of polyphenols like oleuropein and hydroxytyrosol. [56

Because of the antioxidant propeerities, it can prevent oxidative stress caused on cells done by reactive oxygen species (ROS). [7]

ROS is produced because of thyroid hormones like thyroxine which is involved with metabolism. [8]

And reactive oxygen species can damage the DNA, RNA, and proteins of a cell because they are highly reactive molecules, which can lead to cellular death.

Antioxidants like olive leaf extract can reduce free radicals and improve cellular health.

Herolean contains a nice dose here of 300mg olive extract. 

Dark Labs releases limited editions of their Crack pre workout every once in a while…

Caffeine (300mg)

Without caffeine, there is simply no point.

Caffeine is always the go to stimulant for any pre workout.

It’s one of the most researched and proven stimulants to work for increasing performance and strength. [910]

In Herolean, it’s paired with DMAA, DMHA and eria jarensis to create a potent synergy of energy, fat burning and more.

Caffeine stimulates thermogenesis in  the body and it gives you more energy even if you’re in a calorie deficit. [11]

At 300mg, you’re getting more than enough to get the energy and fat burning you need.

Green Coffee Bean Extract (150mg)

Green coffee bean extract (GCE) is basically raw coffee beans that haven’t been roasted yet.

The benefits of this extract come from the chlorogenic acid.

Problem is, most fat burners that contain this extract don't have standardized chlorogenic acid which is where the benefits come from.

It’s a natural and safe compound for fat loss and because it’s in its raw form, the beneficial compounds are going to help with fat loss as it has potent lipolytic activity.

GCE has several benefits that range from being anti inflammatory, to anti diabetic, anti oxidant and even anti-carcinogenic. [12]

It can help with glucose metabolism and regulate lipids. [13]

Researchers have found that GCE helps synthesis cholesterol and downregulate fatty acids while increasing fatty acid oxidation. [14]

Even without caffeine, CGA can free up fatty acids within fat tissue and it will help keep glucose levels in check. [15]

Standardardized to 50% chlorogenic acid

Eria Jarensis (250mg)

Everyone loves the euphoria that comes from some pre workouts.

What brings that mood on is typically from some form of PEA.

However the problem with pure PEA is that it breaks down quickly by the MAO enzyme.

But Eria Jarensis, which is what is used in Herolean, has a longer half life as there's two alkyl groups attached to the PEA part of this molecule.

Eria Jarensis activates the euphoria and enhances mood for hours at a time.

Now this is combined with a big dose of DMHA of 200mg, along with 100mg DMAA.

So this 250mg dose is fairly big, and you can expect some nice waves of euphoria for hours at a time.

And thanks to the 50mg hordenine, this will help prolong those effects for even longer.

DMHA (200mg)

DMHA is well known now to be the alternative and safer version of DMAA.

It's known as 2-aminoisoheptane and it belongs to a group of molecules known as aliphatic amines. [16]

There isn't much research behind this fairly new stimulant but it's similar to DMAA, in that it can increase euphoria by releasing catecholamines and it decreases the speed of reuptake of those same neurotransmitters. 

While the dose here is big at 200mg, there's still 100mg DMAA along with eria jarensis and more. 

The euphoria, energy, and fat loss will be intense, and perhaps too intense for most people at full scoop.

DMAA (100mg)

DMAA or 1,3-Dimethylamylamine, is a hardcore stimulant that was intially introduced as a nasal decongestant.

Since it's been used in supplements in 2006, it's marketed as a weight loss and energy booster.

DMAA ignites the brain's reward system and boosts adrenaline by activating the fight or flight response.

The downside to DMAA is it's potential risk for elevating blood pressure and heart rate. 

But this usually only occurs when the dose is over 75mg. 

And here we are getting 100mg along with DMHA and eria jarensis. 

So it's needless to say, Herolean is not a joke and it's a strong fat burner with intense energy.


Dark Labs has a line up of pre workout formulas that are super strong…

Synephrine (50mg)

Synephrine is a popular stimulant to see in fat burners.

It basically makes the body free up the fatty acids and uses it as a source for energy. [17]

Found in bitter orange, syphrenine has similar effects to ephedrine, but without the harsh side effects. 

The difference is that it’s much safer.

It frees up fatty acids by functioning as a Beta-2 and Beta-3 adrenergic receptor agonist. Like hordenine, it uses fat for energy while sparing glycogen stores in muscles. 

Synephrine is also great for improving mood and energy as it’s been seen in research to have antidepressant effects. [18]

Hordenine (50mg)

When you have PEA ingredients, you need something to prolong the effects. 

Luckily Dark Labs has thought of this and has added 50mg here. 

It will work as an MAO inhibitor, prolonging the effects of the PEA compounds, as well as the mood boost that comes from both DMAA and DMHA. [1920]

It also functions like a beta-2 adrenergic receptor, meaning it'll make the body use fatty acids as energy. 

The 50mg dose here is standard.

GBB (25mg)

This is an ingredient that makes you sweat. 

We’ve never seen it paired with both DMHA and DMAA, so if you tend to be a sweaty person, this will amplify it!

GBB is gamma butyrobetaine and it’s an ingredient that has been shown to increase metabolism. [21]

The body uses this ingredient to create L-carnitine through the gamma-butyrobetaine dioxygenase enzyme (BBD). [22]

As we touched upon with L-carnitine L-tartrate, using carnitine will help shuttle fatty acids into mitochondria that will be used for ATP production.

Research has proven that using GBB will increase the body’s L-carnitine stores, which will increase thermogenesis. [23]

Yohimbine (10mg)

Yohimbine is traditionally used for weight loss and for it's stimulatory properties. 

It works by blocking alpha-2-adrenergic receptors, creating a fat burning environment. Studies show that yohimbine can reduce appetite, increase fat loss and improve male fertility (10-12). [242526]

However the stimulants here are loaded, with 300mg caffeine, 250mg eria jarensis, 200mg DMHA, 100mg DMAA and more, the yohimbine is dosed huge at 10mg with 3mg alpha yohimbine. 

Needless to say, if you're sensitive to yohimbine, you may not want to try Herolean. 

A similar pre workout can be found here if you're looking for something with little to no yohimbine.

Alpha Yohimbine (3mg)

Similar to yohimbine, alpha-yohimbine works by blocking alpha-2-adrenergic receptors, creating an optimal fat loss environment. 

But unlike pure yohimbine, alpha yohimbine is much more mild in side effects, as it doesn’t increase anxiety or jitters. 

However, it’s combined with pure yohimbine, so if you’re sensitive to yohimbine, you may want to go for another pre workout. 

If you like yohimbine, you’ll like Herolean.

I personally have used 15mg yohimbine with a pre workout and have not had any issues.

Black Pepper Extract (10mg)

To help enhance the absorption, black pepper extract is included. 

It enhances the bioavailability of the nutrients and basically every ingredient it’s taken with. [27]

Herolean is a big formula with lots of ingredients that will help with fat loss, so this will help you make the most out of every ingredient in here. [28]

The bioavailability enhancing properties come from the piperine as researchers theorize that this ingredient can increase permeability in the intestinal wall, which allows the other nutrients it’s taken with to enter the bloodstream easily. [29]

How To Take

Herolean is meant to be a pre workout but it’s also great as a pre cardio drink as it has some solid thermogenic ingredients. 

It may be too intense to be taken on a leg day, it’s definitely not going to be easy on the heart, this is going to be as potent as their limited edition Crack.

If you take half a scoop you can still get some strong energy and it will still be stronger than most pre workouts available. 

With half a scoop, you’re getting 100mg DMHA, 50mg DMAA, 150mg caffeine and more. 

A full serving will be hard to handle even for the most experienced stim junkie!

Flame has the best mood support with 500mg eria jarensis and more…


Currently there’s 2 flavors, green apple and tropical punch. 

Dark Labs is quite good with flavoring so expect these to taste really good. 

We don’t really care about flavoring, but Dark Labs is actually one of the better companies for tasty flavors. 


Fat burner powders are far and wide but Herolean is one of the best for its potency on energy and thermogenesis. 

It burns fat through both non-stimulant ingredients and stimulants. 

We’ve never seen GBB used with both DMHA and DMAA, so you will certainly be sweating even if you’re sitting still!

Dark Labs is known for creating strong formulas and this is easily going to be one of their legendary ones if it ever discontinues. 

Try out Herolean if you don't mind the yohimbine dosage in it. 

Since Herolean seems to be out of stock for a while, the best alternative would be combining Caliente by ASC Supplements and Crack by Dark Labs or any pre workout.
