As a fitness trainer, I recommend fat burners to my clients when they ask me for advice on how to shed extra pounds.

When Arsyn (Arsynist) made its way into the market, I was curious about its claims, so I spent several months researching its history, ingredient list, and the science behind it.

Is Arsyn a good choice for those striving to achieve their weight loss goals?

Keep reading and find out the real impact of Arsyn, and if it's the right supplement for you.

Who is it for?

Who is it for?

  • Athletes and fitness enthusiasts looking for a comprehensive fat-burning supplement.
  • Those who can tolerate high levels of stimulants.

Who is it not for?

  • Individuals sensitive to stimulants.
  • Those with pre-existing heart conditions.

Final Verdict

Arsyn is an effective fat burner with high-quality ingredients that boost metabolism and energy levels. While it offers significant benefits, users should be cautious of potential side effects due to the high stimulant content.

What is Arsynist?

Arsynist supplement product

Arsynist is a fairly new fat-burning supplement created by Condemned Labz, a US-based supplements company founded in 2016.

It was created to be an aggressive and powerful fat-burning agent for athletes trying to cut weight quickly.

Arsynist previously went by the name ARSYN. The main reason for the name change was trademark legalities.

However, Condemned Labz did not change the formula despite changing its name and packaging.

However, many websites still sell the old product ARSYN.

Arsynist’s Benefits

According to claims by its creators at Condemned Labz, Arysinist offers the following benefits:

  • Increases focus and energy
  • Curbs hunger
  • Enhances mood
  • Accelerates fat loss
  • Prevents fat storage
  • Boosts metabolism
  • Increases thermogenesis
  • Enhances mental acuity

Moreover, the psychological effects of using a fat burner are often overlooked, yet they play a crucial role in the journey towards weight loss. Arsyn fat burner claims to reduce mental fatigue and brain fog, which can have significant implications for your mental and emotional well-being.

You may experience mood enhancement, better mental focus and motivation, and less stress and anxiety. However, it's important to manage expectations and don't solely rely on the supplement for weight loss.

Ingredients

Supplemental facts of Arsynist

The ingredient list found in Arsynist is quite long compared to some other weight loss supplements on the market, but let’s see what kind of scientific backing lies behind those choices.

Here’s a breakdown of those ingredients:

Vitamin B12

According to an article on the National Institute of Health, vitamin B12 plays a critical role in energy metabolism and is often promoted as an energy and endurance enhancer for athletes [1].

Arsynist contains vitamin B12 in the form of methylcobalamin (at 5000% of your daily value), which is considered the most effective form of vitamin B12 used to treat complications associated with vitamin B12 deficiency [2].

We did notice some clients experienced a boost in their workout endurance about one month in.

L-Tyrosine

L-Tyrosine is an amino acid that your body produces using another amino acid called phenylalanine. An article published on WebMD says that this ingredient may effectively enhance memory and thinking skills, especially under stressful situations [3].

However, its effects on improving your physical performance are very minimal [4].

Caffeine Anhydrous

Caffeine anhydrous is a dehydrated form of caffeine made from the leaves and seeds of coffee plants. This ingredient is often found in energy bars and sports drinks, and it's known to improve athletic performance [5].

A 2016 study found that caffeine anhydrous may be an effective pre-workout before high-intensity exercise [6].

We noticed, most likely due to the caffeine, that Arsynist didn’t sit well with our clients who already had sleep issues.

Aminoisoheptane Hydrochloride Image

2-Aminoisoheptane Hydrochloride

This compound, also known as dimethylhexylamine (DMHA), is often used as an ingredient in dietary supplements to boost workout performance.

A 2018 study found that DMHA affects the body within 15–60 minutes of consumption: it heightens mental focus, increases energy, helps with appetite control, and raises feelings of wellbeing [7].

Despite its benefits, research has shown that certain stimulants appear under the guise of “2-aminoisoheptane” and may cause health risks to consumers [8].

White Willow Extract

This ingredient is obtained from the bark of the white willow tree. A 2015 study reported that willow bark is widely used to possibly increase sports performance and weight loss due to its anti-inflammatory effects [9].

However, none of our clients reported these benefits after using Arsynist.

Matcha Green Tea Powder

Matcha green tea powder is a traditional Japanese type of powdered green tea. It’s often considered the highest quality of tea.

Matcha green tea is included in the formula for the purported weight-loss benefits. A review of 11 studies showed that matcha green tea might not only help with weight loss but also maintain body weight [10].

As I’ve mentioned, some of our clients appeared to show some weight loss after being on Arsynist for a few months.

“In addition to providing trace minerals and vitamins (A, B-complex, C, E, and K), matcha tea is rich in catechin polyphenols – compounds with high antioxidant activity.”

- Dr. Andrew Weil, MD, Director of Andrew Weil Center for Integrative Medicine

Synephrine Hydrochloride

Synephrine Hydrochloride is a naturally-occurring ingredient found in bitter orange extract, and it has been linked to enhanced fat burning, energy expenditure, and fat oxidation following acute resistance training [11].

It may also help curb your appetite and increase energy levels [12].

Quite a few of our clients reported that their appetite had somewhat decreased over the testing period.

Hordenine Hydrochloride

Hordenine hydrochloride is a chemical found in barley, algae, cacti, and certain grasses. It's used in many products that label themselves as a dietary supplement because it has been linked to better athletic performance and increased weight loss [13].

Cayenne Pepper Powder

Cayenne pepper is a popular hot chili in the capsicum family, and it’s used in many traditional Ayurvedic and Chinese medicines.

It contains many antioxidants and is known to help manage weight, relieve pain, reduce swelling, and protect the nervous system [14].

Grapefruit Extract

Grapefruits may help you regulate diabetes, manage fat loss, lower the risk of stroke, control blood pressure, maintain heart health, and promote regularity [15].

A 2006 study showed that including grapefruit in your diet may assist with weight loss [16].

Yohimbine Hydrochloride

Yohimbine is a chemical extract from the native African tree Yohimbe which may also enhance athletic performance, boost weight loss, control high blood pressure, and treat dizziness [17].

“Yohimbe has been proven a potentially effective option for men. The chemical may help to improve sexual function.”

- Dr. Ahmed Zayed, MD, Founder of Zayed MD

Arsynist also contains Grains of Paradise Seeds, which have been associated with enhanced energy expenditure and the prevention of visceral fat accumulation [18].

It also contains ingredients like Vinpocetine, Higenamine Hydrochloride, and Huperzia Serrata, which have all been linked in some way or another to enhanced cognition.

To round up the list there’s Bioperine® which, in addition to possibly helping with the weight loss as well, is included to help with digestion and bioavailability of all these ingredients [19].

Pros
  • Increases energy levels and prevents extreme mental fatigue
  • Accelerates your body's fat-burning ability
  • Curbs your appetite, thereby helping you to lose weight
  • 60-day money-back guarantee if the product doesn’t work for you
Cons
  • It may cause jitters and indigestion for some users
  • Some ingredients may be considered harmful

Does Arsynist Have Any Side Effects?

Lady experiencing headache

Yes, Arsynist does have reported side effects like jitters and indigestion, which may be due to the 150 mg of caffeine it contains. If you're sensitive to this substance, consider avoiding coffee and other supplements that contain it.

Some of my clients also complained about getting sweats, feeling sick, and having an upset stomach.

Arsynist also contains some questionable ingredients like the aforementioned 2-aminoisoheptane, which may pose some health risks to consumers.

It also contains lab-made chemicals such as vinpocetine, for which, in 2019, the FDA issued a warning not to be used during pregnancy. Its status remains controversial even though it's used in dietary supplements.

There’s also a substance banned by the World Anti-Doping Agency called Higenamine Hydrochloride.

So, Arsynist might not be the best fat burner to consume before a contest.

How Does OxyShred Compare to Other Similar Products?

Here's how Condemned Labz Arsyn compares to other most popular and widely used fat burners on the market today.

PhenQ

PhenQ is one of the most effective weight loss supplements on the market.

It promotes fat loss by reducing stored body fat, suppressing appetite, blocking fat production, and increasing energy levels.

Unlike Arsynist, which contains banned substances and potentially harmful stimulants, PhenQ contains only natural enhancers and stimulants.

It may be a bit expensive, but in my experience so far it is well worth the price.

PhenGold

PhenGold

Like Arsynist, I recently explored PhenGold, a dynamic fat burner designed to fast-track weight loss through enhanced appetite suppression and thermogenesis activation

PhenGold stands out with its vegan-friendly formula that enhances weight loss through natural ingredients like green tea and L-tyrosine, supporting fat burning and energy levels.

Unlike Arsynist, it requires a daily intake of three capsules, offering convenience without the need for excessive dosing.

Its effectiveness is complemented by capabilities in boosting metabolism and energy, with the added benefits of mood improvement and appetite suppression, making it a comprehensive weight management solution.

Instant Knockout

Instant Knockout is also a fat burner that accelerates thermogenesis and metabolism to promote fat loss.

However, unlike Arsynist, Instant Knockout users have not reported getting any jitters or an upset stomach.

In my fitness career, Instant Knockout proved to be an all-around fat burner particularly loved by fitness enthusiasts, athletes, and bodybuilders, because it also appears to support muscle growth and strength.

Where Can I Buy Arsynist?

Looking through phone device to buy

You can buy Arsynist on the Condemned Labz official website.

However, they seem to not have the product in stock as of now.

But they give you the option of signing up for an email notification when they’re stocked up with enough units.

Although it’s not available on Amazon, Arsynist can be purchased from various supplement websites.

Given that Arsynist went through a recent name change, many websites still sell it as ARSYN.

If you choose to buy this product, we recommend buying directly from the Condemned Labz website.

This is because we noticed a significant difference in selling prices on the other websites.

What Do Users Have To Say?

We looked at Arsynist reviews from various websites, and the results seem to be pretty mixed:

“Curbs my appetite like crazy. I wasn’t hungry all day. I had to force myself to eat, and was full after a couple bites. Lots of energy without feeling anxious. I love it!!” - Alesia M., Arsynist Website

“I’ve used Arsyn before to help cut some weight and it helped so much during my training. It definitely curbs my hunger and keeps me focused throughout the day.” - Jay O., Arsynist Website

“I haven't seen any visible results from this product, I have been taking it for about 3 weeks. Not lost a pound and have not seen a difference in my body fat. Especially in the abdominal area. The only positive thing is that it makes me more alert. That's due to high caffeine in this product. Not so happy with this product as of today.” - Rene V., Arsynist Website

“Gives me the shakes, sweats, and sick to my stomach. Had to stop taking it” - Lora S., Arsynist Website

FAQs

Who Should Avoid Arysnist?

People under 18 should avoid Arsynist, as well as those who have a medical condition, are under any prescription drugs or happen to be pregnant or breastfeeding. Do seek professional medical advice before taking this product, especially if you have a serious medical condition.

Is It FDA Approved?

No, Arsynist is not FDA-approved even though it’s made in an FDA-registered facility.

Is It Vegan Friendly?

No, Arsynist isn't vegan-friendly. While all the main ingredients are vegan-friendly, Arsynist capsules contain gelatin.

Does It Work for Women?

Yes, Arynsist works for women too. Even though most users of this supplement seem to be men, it can also help women burn fat.

Our Verdict on the Arsyn Thermogenic Fat Burner

Having personally tested Arsyn fat burner, I noticed a mild boost in my energy and focus. Appetite suppression was another benefit, helping me manage cravings better.

However, its high caffeine content might not suit everyone, especially those sensitive to stimulants. While Arsyn is a robust supplement, I recommend considering PhenQ as an alternative, especially for those looking for a more natural option with fewer stimulants.

PhenQ has shown impressive results in fat burning and appetite control, making it a great alternative to Arsyn in your fitness journey.

It’s not a magic pill, but you’ll get to your goals noticeably quicker and without any harm to your health.
