arsynist review

Fat loss can be a tough process. Not only is it difficult to maintain a caloric deficit over time, you often deal with other confounding factors like brain fog, irritability, and low energy.

But now there are fat loss supplements out there designed to specifically address all obstacles in the fat loss process so you can limit those mental and physical barriers as much as possible.

And Arsynist, by Condemned Labz, claims to be one of those comprehensive fat burners. So go ahead and dive deep into our full Arsynist review to see what specific benefits this fat burner has and if it’s better than other options out there!

About Arsynist

Arsynist is advertised as a comprehensive fat-burning supplement, crafted by Condemned Labz. The formula contains many different stimulants, such as caffeine, synephrine, hordenine, and yohimbine. 


As a result, it’s meant for only the most dedicated individuals who want a highly potent fat-loss formula to get shredded as quickly as possible. 

But it’s more than stimulants too, as it also includes appetite suppressants like cayenne and general ingredients to boost mood, including Huperzine A. Put it all together, and Condemned Labz Arsyinist was created to make your fat loss journey less of a grind and easier to complete. 

Arsynist Benefits

Arsynist is specifically formulated to give users the following benefits:

  • Increased Fat Burning
  • Diminished Fat Storage
  • Heightened Mood
  • Appetite Control

Increased Fat Burning

So many people struggle to shred fat, even if they think they’re working out hard and eating right. The truth is, sometimes you need a little more help to really jumpstart your metabolism.

And Arsyinist claims to naturally increase fat-burning by using a number of metabolic enhancers, such as caffeine anhydrous, synephrine, and yohimbine. These are designed to synergistically ramp up calorie-burning and fat loss. 

Arsynist For Fat Burning

Diminished Fat Storage

Another problem people have is their body tends to store fat quite easily, rather than use it as fuel. 

Condemned Labz Arsynist is advertised to halt this fat storage process so you can get rid of stubborn body fat from all areas. Some of the ingredients designed to do this are grains of paradise and matcha green tea, among others.

Heightened Mood

Going through a cut can definitely put you in a bad mood. You may experience irritability, brain fog, or excess stress that really makes fat loss seem like a grind. 

Arsynist claims to heighten your mood and cognitive function, not only with caffeine and natural energizers, but also with various nootropics such as Huperzine A. 

Appetite Control

Hunger pangs and cravings are other huge obstacles when losing fat. And unless you have ironclad discipline, you’re bound to give in at some point.

Condemned Labz Arsynist is advertised to give you the power back over your appetite so you can healthily manage cravings and get through even the toughest fat loss diets. This is all thanks to cayenne, hordenine, and other natural appetite suppressants. 

In sum, these four benefits are what most people look for when trying to lose fat. 

But does Arsynist really work for fat loss? 

You’ll have to read on to find out!

Arsynist Ingredients

Condemned Labz Arsynist has 16 active ingredients. It’s a mix of amino acids, vitamins, stimulants, and herbal extracts. 

Below are all of the Arsynist Ingredients:

  • Vitamin B12
  • Tyrosine
  • Caffeine Anhydrous
  • 2-Aminoisoheptane Hydrochloride
  • White Willow Bark Extract
  • Matcha Green Tea Powder
  • Synephrine Hydrochloride
  • Higenamine Hydrochloride
  • Hordenine Hydrochloride
  • Cayenne Pepper Powder
  • Grapefruit Seed Extract
  • Paradoxine Grains of Paradise Extract
  • Vinpocetine
  • BioPerine Black Pepper Extract
  • Yohimbine Hydrochloride
  • Huperzia Serrata
Arsynist Supplement Facts

Vitamin B12 (300mcg)

Arsynist has a really high dose of vitamin B12, which is one of the B-complex vitamins. We’re glad to see it’s in methylcobalamin form, which is the most bioavailable. 

This vitamin is critical for energy production and metabolism. And research shows you need to get enough of it in order to be at a healthy weight.

However, it’s not clear if supplementing in huge doses has any clear benefits if you’re already getting enough.

L-Tyrosine (375mg)

L-tyrosine is an amino acid that helps to create dopamine and norepinephrine. These are neurotransmitters (brain chemicals) that increase alertness, motivation, and energy levels. 

However, they can be depleted during stress, which includes dieting. Some evidence shows that tyrosine supplementation may help to improve brain performance when under stress, mainly by making sure those brain chemicals stay at solid levels. 

So basically it may help to reduce brain fog and keep you mentally stable. 

Caffeine Anhydrous (300mg)

There’s 300mg of caffeine anhydrous in Arsynist, which is more than you get from 3 cups of coffee. 

This is one of the most well-known stimulants out there. It ramps up brain and nervous system activity which may increase alertness, energy, and mental well-being.

But its stimulating effects might also speed up your metabolism and the body’s natural fat-burning processes. So it’s a one-two punch for energy and fat loss

White Willow Bark Extract (100mg)

White willow bark is a common herbal remedy mainly used for pain. In fact, salicin and other compounds in it do have some pretty strong anti-inflammatory and analgesic effects

There isn’t much evidence for fat loss though, although it could theoretically boost metabolism. 

Matcha Green Tea Powder (50mg)

Matcha green tea is a unique form of green tea that’s rich in many health-boosting compounds.

For one, it contains EGCG and other catechins that offer anti-inflammatory effects and may also improve blood sugar and metabolism.

Plus, the caffeine and theanine in it may work synergistically to support cognitive function and brain health. 

The problem is Arsynist doesn’t have a very high dose of it.

Other Stimulants

Arsynist also includes other stimulants that have very similar effects. These include 2-aminoisoheptane, synephrine, hordenine, higenamine, and yohimbine. 

Basically, all of these compounds increase noradrenaline, which has stimulatory effects and may increase fat burning and fat metabolism. Their effects on energy also make them useful for pre-workouts, which is why 5150 Pre-Workout and other supplements use them. 

None of these are very well-researched though, and yohimbine is really the only one with any clinical research. 

Cayenne Pepper Powder (25mg)

Cayenne peppers are not only good for making your mouth burn like crazy. They also contain capsaicinoids, which are compounds that may increase fat-burning and metabolism.

Plus, cayenne pepper seems to be able to reduce appetite and cravings. Overall, the effects of cayenne are likely not huge, but it still seems like a nice additive for weight loss

Grapefruit Seed Extract 10:1 (25mg)

We all know grapefruit as a healthy food. And you may have even heard of that crazy grapefruit diet fad that was popular a while ago.

And in general, grapefruit does seem helpful for weight management. There isn’t much research on grapefruit seeds specifically though. One study showed that grapefruit seeds may increase fat metabolism and decrease fat storage, but that wasn’t done on humans. 

Paradoxine Grains of Paradise Extract (15mg)

Paradoxine is a trademarked form of grains of paradise extract. This is an herbal extract which may be able to stimulate brown fat levels, which ultimately turns body fat into energy in a process called thermogenesis.

Simply put, Paradoxine may increase your body’s ability to burn for for energy rather than storing it as body fat. 

If you want a particularly high dose of Paradoxine, Steel Shredded AF is a good choice since it has 50mg instead of just 15.

Vinpocetine (5mg)

Vinpocetine is a compound found in the periwinkle plant. It is often used as a nootropic since it can increase brain blood flow and decrease brain inflammation.

Some research shows vinpocetine may also improve memory, but there isn’t much evidence for brain fog or other cognitive symptoms. 

BioPerine Black Pepper Extract (5mg)

BioPerine is a trademarked form of black pepper extract. It’s often used alongside other ingredients because the piperine in it can increase nutrient absorption and bioavailability

Huperzia Serrata (300mcg)

Huperzia serrata (or toothed clubmoss) is a natural herb with a high concentration of Huperzine A. This compound can increase acetylcholine levels and may protect the brain from damage.

Whether or not it actually increases cognitive function in healthy people is still up for debate though. 

Does Arsynist Work?

Overall, Arsynist seems likely to work, particularly for increasing metabolism and fat burning.

Arsynist is filled with caffeine and other stimulants that likely ramp up metabolism and help the body burn fat for energy. These may also naturally improve mental energy levels too.

It also has some ingredients that may be beneficial for brain function, such as tyrosine and Huperzia serrata, although these aren’t dosed very high.

Also, keep in mind that many of the stimulants haven’t been researched thoroughly, so their benefits are mainly hypothetical.

Claims vs. Reality

Condemned Labz doesn’t make any huge claims about Arsynist, so these are generally supported.

After all, Arsynist should very likely aid fat burning, decrease fat storage, increase energy/mood, and reduce appetite. But the degree of effects varies from person to person. 

Most fat burners are capable of helping you lose a few extra pounds over the course of several weeks, not 10 to 20 pounds in a matter of a week, so be realistic too.

How Does Arsynist Compare?

Compared to other fat burners, Arsynist definition focuses more on stimulants and has higher doses of these.

This is fine if you’re someone who likes all of these effects. But it also increases the likelihood of side effects, which we’ll talk about below. 

It could’ve been better by using a more well-rounded line-up of ingredients. But again, it still might be good for you especially if you like stimulant-based fat burners. 

What’s good about Arsynist is that it has a fully transparent label. And this is especially important when you have high-stim ingredients. This sets it apart from other supplements, such as Synedrex, which has very similar ingredients (e.g. caffeine, synephrine, hordenine, higenamine) yet jams all of them into a proprietary blend. 

Another similarly formulated supplement is Huge Supplements Exterminate. It contains a much higher dose of green tea extract at 600mg per serving, along with stimulants such as synephrine and hordenine. These may offer benefits for metabolism, fat burning, and energy. Plus, it includes T2 for additional metabolism support and huperzine A for cognitive support. Exterminate and Arsynist are likely both good choices, and they cost somewhat similar too ($49.95 and $44.99, respectively). 

Who is Arsynist Best For?

Arsynist is best for people who want a high-stim supplement to increase metabolism and fat-burning and would like to lose fat faster and more easily. 

It is also a good choice for people who really want to reduce cravings and appetite too, as the stimulants and other ingredients may help with that. 

How to Take Arsynist

Arsynist comes in capsule form. Condemned Labz recommends taking one serving (two capsules) on training days with 8 to 12oz of water after waking. 

Some individuals may prefer to take it with food due to the potency. 

On non-training days, you can take it after waking too, but you might not need as high of a dose.

Is Arsynist Safe?

Unfortunately, Arsynist has some potentially concerning ingredients. This is especially true for hordenine, higenamine, yohimbine, and synephrine. In fact, higenamine is on the WADA-banned substance list. And other ingredients in Arsynist are on the monitoring list.

These are all stimulants and they aren’t very well-researched in humans. Due to their stimulating effects, they may cause:

  • Agitation
  • Anxiety
  • Increased blood pressure
  • Tachycardia (fast heart rate)
  • Sweating
  • Trouble sleeping

Other possible side effects of Arsynist are:

  • Headache
  • Heartburn
  • Other digestive issues
  • Allergic reactions or sensitivities

Condemned Labz Arsynist is made in the USA in a cGMP, FDA-registered facility. They don’t list any info for allergens or dietary restrictions.

Verdict: Arsynist Review

Arsynist is a pretty powerful fat burner, at least as far as its stimulant content. That’s why it’s only for a certain portion of the fitness community that wants to take a high-stim fat burner.

This supplement definitely has the potential to deliver big increases in metabolism and fat-burning. But also be aware that the risk of side effects is higher than most fat burners that are out there.

Ultimately, it comes down to personal preferences and goals. And if you tolerate it, Arsynist certainly could help elevate fat loss, give you more energy, and make you lose weight a bit quicker.
