Blackstone Lab’s Fat Burners (Review)

Blackstone Lab’s Fat Burners (Review)

Selecting a fat burner can be a hard decision. There are a lot of factors that play into what makes a fat burner good; and what makes it good for you. But Blackstone Labs made it easier by creating a fat burner for levels of stim-tolerance. In this weight loss guide we’re going to go over Blackstone Lab’s 3 stimulant-based fat burners: Paraburn, Viper X and Arson Fat Burner. 3

If you want to jump ahead:

But if you’re in the market for a non-stim fat burner we would recommend checking out Trojan Horse.


You may be wondering:

‘Whats the big deal? The stronger the fat burner, the better the results right?’

Wrong. We are all different, and our experiences and results will differ as well. Because of this, what works for some individuals may not work for you. That’s why we like to see brands with a variety of products to select from.

The FDA recommends healthy adults to consume a max of 400mg of caffeine in a day. (1) This is equal to about four 8oz coffees. Now there are products (like pre workouts) that have 400mg of caffeine per serving. That’s not including the other stimulants.

This is why we recommend you assess your tolerance to stimulants. As well as go on routine “breaks” to allow you body to regain it’s sensitivity.

Blackstone Labs Paraburn: Beginner Level

Blackstone labs weight loss guide paraburn

PARABURN blackstone lab weight loss guide

Paraburn is Blackstone lab’s beginner level fat burner. Don’t let that feign you away, you can still have promising results and weight loss without all the stims.


The Label

As you can see by the label, it’s a pretty simple ingredient list. Starting from the top we have:

  • Caffeine
  • Achyranthes Aspera
  • Theobromine
  • Capsaicin
  • 6 Paradol
  • 3,3 Diiodothyronine
Stimulants/Appetite Suppression

In this category we have Caffeine and Theobromine.
Caffeine is a good base stimulant to set the foundation for the more stimulants. Caffeine and Theobromine are both found in cacao plants and tea leaves. In a fat burner, they provide energy and may help shed water weight. Like other stimulants, theobromine and caffeine also may aid in appetite suppression. (2,3)


In Paraburn we have a couple of different thermogenic ingredients. First we have a classic ingredient Capsaicin. Capsaicin is an active component of chili peppers, and other peppers. Through increasing your metabolism, Capsaicin helps your body burn more calories. Like Capsaicin, Paradol is the active flavor component of the seeds of Guinea pepper. Thus increases weight loss through thermogenesis.(4,5)

What Makes It different?

There are two ingredients that we don’t see often in other fat burners that are in Paraburn:

Achyranthes aspera and 3,3′-Diiodothyronine

Achyranthes aspera comes from a plant species native to tropical climates. This ingredient may increase calorie burning by enhancing thyroid function.
The last ingredient is 3,3-Diiodothyronine. 3,3-Diiodothyronineis a metabolite of thyroid hormone necessary for metabolic functions.(6,7)

What To Expect

Paraburn isn’t your stim-heavy fat burner but you can still expect some energy. We expect the appetite suppression and energy to be the most prominent effects.

Blackstone Labs Viper X: Intermediate Level

Blackstone labs viper x weight loss guide

VIPER-X-FAT-BURNER Blackstone labs weight loss guide

Viper X is Cobra 6P’s replacements. So if you were a fan of that formula this is the product for you.

The Label

As we mentioned above, Viper X is the replacement for Cobra 6P. But the formula isn’t exactly the same. There are 3 noticeable differences.

First, Viper X is full disclosed like most of Blackstone labs’ products. Whereas Cobra 6P was a prop blend. So although they share a lot of the same ingredients we wouldn’t be able to tell you if it’s at the same dose.

Second, Viper X contains more mg of active ingredients than Cobra 6P. Where Cobra 6P had 675mgs, Viper X has 720mg.
Lastly, the only ingredient swap between these products is:

Yohimbine → Eria Jarensis

Eria Jarensis a plant in the orchid family. And it is the only plant (that we know of) to supply N-phenethyl dimethylamine.

The rest of the ingredients in Viper X are:
  • Caffeine Anhydrous
  • Achyranthes Aspera
  • Hordenine
  • N-Methyl Tyramine
  • Theobromine
  • Teacrine
  • Advantra Z
  • Bioperine
Stimulants/Appetite Suppression

Because Viper X is an intermediate fat burner, you can expect more stimulants. This includes the Caffeine Anhydrous and Theobromine like we saw in Paraburn. As well as, Teacrine, Advantra Z (Synephrine), N-Methyl Tyramine and Eria Jarensis. (8,9,10,11)

Mood Support/Focus

Unlike in Paraburn, Viper X has ingredients with the purpose of improving your mood and focus. These include cross over ingredients from the stimulant section:

N-Methyl Tyramine and Eria Jarensis

Both N-Methyl Tyramine and Eria Jarensis relate to the PEA (“feel-good” alkaloid).


We have a couple of ingredients with thermogenic properties. This includes Advantra Z, N-Methyl Tyramine and Hordenine. Synephrine helps kick start lipolysis and stimulates metabolism. While Hordenine ramps up the body’s natural fat burning abilities. It does this by stimulating norepinephrine release.(12)

Lastly we have the Achyranthes Aspera, as we saw in Paraburn, and Bioperine. Bioperine may increase the bioavailablity of the other fat burning ingredients.(13)

Noteworthy!VIPER-X-POWDER blackstone labs weight loss

Viper X comes in both a pill and powder form. So if you’re not crazy about taking pills or rather use it as a pre workout, there’s an option for you.
The powder form does have variations in the formula. Which includes a good chuck of stimulants.
Instead of :

  • Eria Jarensis
  • Hordenine
  • TeaCrine
  • N-Methyl Tyramine

We have:

  • Higenamine
  • Deng Zen Cao

Higenamine exhibits similar fat oxidation effects to that of ephedrine. But without all the risks. With the fat oxidation, you’ll also get some energy and focus.(14)

Deng Zen Cao is a mild diuretic related to the Juncus Effusus plant. So this ingredient is going to help with shedding water weight and decrease bloating. (15)

Flavors: Watermelon and Kiwi Strawberry

What To Expect

Viper X is definitely more stimulant based than Paraburn. So with that we expect there to be more energy and more appetite suppression. But Viper X contains more thermogenic ingredients as well. Thus there may be more calories burned during workouts and may even help you sweat more in the gym.

Because the powder has less stimulants it may not be as intense as the pill version. But including the diuretic may result in some more immediate “weight loss”. Of course this would be most likely from water weight, not fat loss. If you take this product before the gym, you may sweat more than from the pill.

*With any fat burner you need to make sure you’re drinking plenty of water to stay hydrated. With this version of Viper X , we want to emphasize this.

Blackstone Labs Arson Fat Burner: Advanced Level

ARSON FAT BURNER blackstone labs weight loss guide

ARSON-INGREDIENTS blackstone labs weight loss guide


Our last fat burner, is also our newest and strongest addition; Arson Fat burner.

The Label

Just by looking at the label you can see Arson Fat Burner contains a lot more ingredients than the others. For a total of 601mgs of active ingredients per servings you’re getting two prop blends.

In our first blend we have:

  • Eria Jarensis Extract
  • Caffeine Anhydrous
  • 2-Aminoisoheptane HCl
  • Theobromine Anhydrous
  • Green Tea Extract

Based off this section alone, Arson contains not only a lot of stims, but potent ones. Arson is a prop blend, but Blackstone confirmed there is 125mgs of 2-Aminoisoheptane.

2-Aminoisoheptane HCl, also known as DMHA, is the potent stimulant used to replace DMAA. In fact, 2-aminoisoheptane shares similar structures to that of DMAA. DMAA and 2-aminoisoheptane actually work in the same fashion. They both boost dopamine and noradrenaline uptake, while slowing down re-uptake.(16)

Also we have Green Tea Extract. Now don’t let the lack of a cool scientific name throw you off. There are a ton of research on Green Tea’s effect on weight loss. (17)

To name a few of the benefits:

  • May improve your body’s efficiency at burning calories (18)
  • May help improve exercise performance (19)
  • Can help reduce visceral (belly fat) and inflammation(20)

.. and the benefits continue.

The second blend is where the heat come ins.arson-fat-burner-citrus-compressor

The Citrus-Rx Blend contains:

  • Citrus Nat Sudaidai Hayata Extract
  • Citrus Junos Siebal
  • Ex Tanaka Extract
  • Citrus limonium Extract
  • Citrus Aurantium Extract
  • Cayenne Pepper Fruit Extract (Capsimax®)
  • Yohimbe Extract
  • Grains of Paradise
  • Black Pepper extract

In the Citrus-Rx Blend we have 5 citrus extracts. Citrus Aurantium Extract (Synephrine) is the most common extract we see in fat burners. But what’s more important is that there is a ton of research backing up the effect of it.
In general, citrus extract will help kick start lipolysis and suppress your appetite. While also providing an energy boost. (21, 22)

All the following ingredients are also common in a fat burner. But not typically seen together. Which is one more way we know Arson is going to be an intense thermogenic.

First we have Cayenne Pepper Fruit Extract which contains Capsaicin. So this is going to promote thermogenic effects and boost your metabolism.

Next up we have the Yohimbe Extract. Which supplements use for a lot of things such as impotence, performance aid, weight loss, and more.(23)

Our last different ingredient is Grains of Paradise also known as Paradoxine. Grains of Paradise contains the active compound 6 Paradol, as well as other compounds. This and Bioperine Black Pepper Extract, were both seen in Blackstone’s Paraburn and Viper X.(24)

Now for the question everyone wants to know..

Is It Like King Cobra?

King Cobra contained a proprietary blend consisting of 785mg of active ingredients. Compared to Arson’s 601mg of active ingredients, Arson falls a little short.

But lets compare the ingredients!Arson Fat Burner King Cobra viper x paraburn

In King Cobra we had :

  • Ilex Guayusa Extract
  • Green Tea ExtractArson fat burner paraburn viper x check
  • Theobroma Cocoa ExtractArson fat burner paraburn viper x check
  • Eria JarensisArson fat burner paraburn viper x check
  • Aframomum Melegueta Extract (as Paradoxine)Arson fat burner paraburn viper x check
  • CapsimaxArson fat burner paraburn viper x check
  • Bioperine Black Pepper ExtractArson fat burner paraburn viper x check
  • Erythropalum Scandens Ethanolic Extract
  • 1,3 Dimethylamylamine HCl
  • Citrus Aurantium ExtractArson fat burner paraburn viper x check
  • Yohimbe ExtractArson fat burner paraburn viper x check

As you can see, we’ve already checked off all the ingredients shared between the products. So whats left is:

  • Ilex Guayusa Extract
  • Erythropalum Scandens Ethanolic Extract
  • 1,3 Dimethylamylamine HCl

Ilex Guayusa Extract comes from the Holly Tree and is a source of caffeine. In fact you may recognize it in the form of tea; Guayusa tea. Its actually very similar in benefits to Green Tea and Yerba Mate. (25) We don’t have a direct ingredient to compare this to, Arson does have simple and reliable Caffeine.

Next up we have Erythropalum Scandens Ethanolic Extract in King Cobra. Which is generally useful as a anti-inflammatory/ anti-obesity ingredient(26). Again we don’t have a direct comparison for this ingredient. But it would be the most like the Citrus Extracts in Arson.

And finally, we have 1,3 Dimethylamylamine HCL (DMAA) in King Cobra. As we mentioned above DMAA and DMHA are very similar. So these ingredients would be the most comparable. And most products that once contained DMAA, now feature DMHA (like Dust X).

What To Expect

Right off the bat we expect Arson Fat Burner to be strong. So if you have low tolerance to stimulants, this is not the fat burner for you. Will it be as good as King Cobra? We expect it to be in that neighborhood of intensity. Appetite suppression, energy and focus are likely to be high due to the amount of stims. We also expect the thermogenesis to be pretty strong as well due to all the Citrus extracts. Based on the label, Arson is one of the (if not the) strongest fat burners we carry. But it’s up to you let us know how it compares to what you’ve already tried. So if you do checkout Arson Fat Burner, don’t forget to leave a review!
