Dark Labs asked…

How do you like eria jarensis?

Now how does 220mg eria combined with 220mg DMHA sound?

Dark Labs has redone and reformulated Flame 3 times now.

This is the 3rd version.

They've pushed limited with CrackHerolean and now Flame.

They’ve made holiday special editions of Crack, like Halloween and Christmas.

And now Crack Reloaded is another pre workout that's been released. 

Flame breaks all kinds of records.

It’s packed with 220mg eria jarensis, 220mg DMHA, 400mg caffeine, it’s a monster of a pre workout. 

This is a pre-workout that you get if you want the mood and energy, without the banned stimulants like DMAA.

What To Expect

With the giant doses of exotic stimulants here, you’ll be sure to get waves of euphoria, energy and motivation all day long. 

Unlike the hard hitters, like Excelsior, the uplift in mood lasts for hours, you won’t even notice it when it starts to wear off after 8 hours as it’s not as severe of a crash. 

And if you’ve tried Herolean and didn’t like the high doses of yohimbine, you’ll like Flame as it has just under 1.5mg instead of 10mg.


Flame is a monster of a pre workout. 

You’ve probably seen every type of pre workout. 

High doses DMAA, mixed with both DMHA and DMAA, or even all 3 including eria jarensis.

Flame takes what people like the most and uses high doses of it.

On top of 400mg caffeine, there’s 300mg DMHA, and 500mg eria jarensis

The energy is just top notch here and the euphoria is long lasting.

Not to mention, there’s no other pre workout that uses this much eria jarensis. 

People who have taken 300mg eria jarensis will probably be able to handle this much.

Agmatine (1g)

Agmatine is best known for it’s nitric oxide boosting enhancements. 

It acts like a defense when it comes to N.O. and it also has some nootropic benefits as it can uplift mood. 

Agmatine can stimulate nitric oxide synthase, meaning it will elevate nitric oxide production, leaving you with more pumps that last for long periods of time. 

It can also prevent the breakdown of arginine, but since there isn't a source of citrulline in Flame to increase arginine, you’ll still have nasty long lasting pumps here. 

It features a full gram of it here, and along with pumps, it has some nice mental function enhancing benefits.

Arginine AKG (500mg)

Arginine Alpha-ketoglutarate (AAKG) is a compound made from the amino acid L-Arginine and Alpha-ketoglutarate, a substance formed in the body's energy-generating process.

It's often used in pre-workout supplements due to its potential benefits for athletic performance and muscle building.

L-Arginine, a component of AAKG, is a nonessential amino acid, meaning the body can produce it on its own. It's also found in many foods.

L-Arginine is known to help build muscle mass and improve performance.

It plays a crucial role in nitric oxide synthesis in the body, which is essential for blood vessel dilation.

This dilation can enhance blood flow to the muscles during workouts, potentially improving workout performance and muscle recovery.

Alpha-ketoglutarate, the other component of AAKG, is a key player in the Krebs cycle, a metabolic pathway involved in energy production and the breakdown of nutrients like proteins and carbohydrates.

While there's limited research on Alpha-ketoglutarate's direct benefits for exercise performance, its role in energy metabolism suggests it could potentially support sustained energy levels during workouts.

Check out this list if you want to find more pump supplements.

Beta Phenylethylamine (300mg)

Beta Phenylethylamine is a naturally occurring compound found in some foods like chocolate.

It is also a central nervous system stimulant that increases levels of several neurotransmitters in the brain, such as dopamine, norepinephrine, and serotonin.

These neurotransmitters play an essential role in regulating mood, focus, and energy levels.

Beta Phenylethylamine is similar in structure to other stimulants like DMAA and PEA. It's often used in pre-workout supplements for its mood-enhancing and focus-boosting effects.

However, it's worth noting that high doses of Beta Phenylethylamine can potentially lead to mood swings and other side effects.

Caffeine (300mg)

Caffeine is the grandfather of all stimulants, as it has decades of research proving it’s worth for physical and mental enhancements.

There’s a big 300mg dose of caffeine here, and on top of that is 100mg citrate. 

Caffeine citrate is a much faster absorbing form. 

Several studies show this stimulant as an effective performance booster for both high and low intensity exercises. [2]

So on top of 300mg of caffeine, you'll get rapidly absorbing caffeine citrate.  

DMHA (220mg)

DMHA is traditionally known as 2-aminoisoheptane, and it's a hardcore stimulant that belongs in a class of stims called aliphatic amines. [6]

This stimulant is often referred to as a king of stimulants because of how strong it is, and it helps being globally available, with the exception of Australia banning the sale of it.

DMHA provides a strong source of focus and energy by releasing catecholamines and it slows down the reuptake of these neurotransmitters. 

At 300mg, you'll want to expect some strong energy and focus especially considering how there's 500mg on top of this.

Eria Jarensis (220mg)

Eria is known to increase energy by working as a potent neuromodulator, and while there isn’t enough research on this ingredient, we know it binds to the receptor of the brain. 

It's believed to increase levels of dopamine and noradrenaline in the body, which can help to improve mood, focus, and energy levels. However, high doses of Eria Jarensis can potentially lead to side effects like rapid heart rate, increased blood pressure, and shortness of breath.

It functions as a neurotransmitter and releases dopamine with the receptors that it activates. 

Euphoria, energy, and motivation are what you’ll get with eria jarensis. 

Typically, pre-workouts will have anywhere between 150mg to 250mg on average.

While some push it to 300mg, as Dark Labs has with the Gold edition of Crack, this is the first we’ve seen with this big dose at 500mg. 

You’ll get some intense waves of euphoria and lots of energy at this big of a dose.

Caffeine Citrate (200mg)

Caffeine Citrate is another form of caffeine that is often used in pre-workout supplements like Flame by Dark Labs.

The key difference between caffeine citrate and regular caffeine (caffeine anhydrous) is the speed at which it is absorbed into the body.

Caffeine citrate is known to act faster than its anhydrous counterpart, providing a quicker energy boost.

This can be particularly beneficial in a pre-workout context, where users are looking for an immediate increase in energy and focus.

However, there's a trade-off. While caffeine citrate acts faster, it provides less actual caffeine per milligram compared to caffeine anhydrous. Specifically, 20mg of caffeine citrate only delivers 10mg of active caffeine.

This means that, milligram for milligram, caffeine citrate provides 50% less caffeine than caffeine anhydrous.

Therefore, the dosage of caffeine citrate in a supplement might be higher than that of caffeine anhydrous to achieve the same total amount of active caffeine.

In Flame by Dark Labs, the inclusion of 200mg of caffeine citrate is designed to provide a rapid onset of energy, helping users to start their workouts with a bang. This quick hit of energy can be crucial in high-intensity workouts, where a fast start can set the tone for the entire session.

Isopropylnorsynephrine Hcl (50mg)

Isopropylnorsynephrine Hcl is a less commonly known compound and there is limited research available on its effects, especially at the dosage of 50mg.

It is believed to be a lipolytic agent, which means it may help to break down fat in the body. However, due to the lack of extensive research, the potential benefits and risks of this compound are not well-understood.

Naringin (25mg)

Found in grapefruits, naringin is a polyphenol that has brought all the marketing in the grapefruit diet. 

It helps with weight loss but nothing to write home about. [8]

Naringin has great energy effects as it can inhibit phosphodiesterase (PDE) enzymes [9] which works in the body as energy inhibitors. 

Inhibiting PDE enzymes will allow energy production to function at it’s highest so it provides uninterrupted energy while increasing metabolic rate.

Alpha Yohimbine (1.5mg)

Alpha Yohimbine is nearly the same as regular yohimbine, in that it can block alpha-2-adrenergic receptors to help create a fat burning environment.

It can also reduce appetite, enhance male fertility [10]

The 1.5mg is quite good as it's already paired with strong stimulants. 

Unlike yohimbine, it doesn't have the same negative effects of anxiety, headaches, nervousness and irritability that people often complain about. [11]

And it has a range of benefits from increasing energy to improving mood, libido and even appetite suppression. 

Although Flame isn’t made to be a fat burner, don’t be surprised if you lose a few pounds after going through a container.


Flavors shouldn’t matter, it’s the last thing we consider. 

But if it tastes good, we’re all up for it. 

So far there are 3 flavors:

  • Blueberry Lemonade
  • Rainbow Candy
  • Refreshing watermelon

I wouldn’t be surprised if they release much more flavors.
