Instant Knockout vs Performix SST

Our Instant Knockout vs Performix SST pits two big brands against one another.

When it comes to fat burning, a famous brand doesn’t always mean a safe and effective product. It should be noted that some great options in this area come from surprising sources and we have found a lot of exciting brands to be big let downs.

So, which category will these two fall into today?

In order to impress, they need to do the following well:

  • Burn fat effectively
  • Be safe
  • Suppress appetite
  • Increase energy

Anything less than this will not be good enough.

Let’s start by getting to know them a little.

Instant Knockout vs Performix SST: Who Makes These Fat Burners?

Roar AmbitionInstant Knockout fat burner supplement review

Here we have the company behind Instant Knockout.

Based in the UK, they have built up an excellent reputation online. With so many before and after profiles, there is enough evidence out there to suggest that they are the real deal.

We like that they review and amend their ingredient profiles regularly. This means the customer is getting an up to date version at all times.

This product comes with a big 90 – day money back guarantee. This means you get the chance to try it on for size and makes purchasing risk free.

They also have some impressive endorsements. UFC fighter Diego Sanchez puts his name to Instant Knockout, he uses it to make weight before a bout.

Former Mr. Universe Robby Robinson endorses their T Booster TestoFuel.

The second company today are proud of their TERRA beads time-release capsules.

This is their method of delivering their nutrients throughout the day. Although it sounds good, it hasn’t caught on and appears to be a bit of a gimmick. There isn’t a lot of solid evidence behind it really.

They have some endorsements but these aren’t the biggest of names unless you are really in the know in the industry.

Performix says that they ”pride ourselves on the use of novel, disruptive technologies that make our products more effective’’. With a good selection of products, they have everything from male performance enhancers to products for tone and shape.

There is even the opportunity to receive regular packs of their products and save 10%, we will find out if this is worth doing soon.

Instant Knockout vs Performix SST Ingredients

Now we can really see which is the better product.

The early signs aren’t great for Performix though. Their use of a proprietary blend means we don’t get to see a lot of the dosages.

Also, their advise of taking 2 capsules once a day doesn’t spread out the benefits in the same way as Instant Knockouts one capsule 3-4 times a day.

Mutual Ingredients

Caffeine Anhydrous

A good start from both.

This is certainly an ingredient you see in fat burners and the energy boost you will get is a good place to start.

If you are using fat burner alongside a diet that restricts calories then this will be very welcome. Not to mention the added benefits for your gym workout.

It will speed up metabolism and get the body burning fat. It has so many uses that it wouldn’t be out of place in a nootropic or pre-workout supplement. It is good that both products have included the anhydrous version.

This means it is a powdered form that is easily absorbed and fast acting. It is a popular ingredient in energy drinks for this reason.

Still, you need the dosage information here. Although it will increase your focus and make you more alert, you want to know if you are getting a safe amount.

In Instant Knockout, we know that we are getting a great 350 mg across 4 servings. This will spread out the effects and also ensure it is well tolerated.

The lack of dosage information from Performix SST means you could be at risk from potential side effects from too much Caffeine. These include anxiety, jitters, high blood pressure, irritability, insomnia, upset stomach and more.

Black Pepper Extract

A good ingredient, if the other nutrients are worth consuming.

This is because it doesn’t burn fat directly, but enhances the capabilities of other ingredients.

As long as these products get their formulas right, it is a good inclusion.

Vitamin B12

A good B-vitamin that stops us from storing as much fat.

It isn’t something we can create naturally so supplementing it can be a good idea. This is, even more, the case for vegetarians and vegans because prominent sources are fish, meat, and dairy.

The 10 mcg in Instant Knockout is all you need. We aren’t given the dosage for Performix SST.

Individual Ingredients

Instant Knockout

Green Tea Extract

One of the best natural fat burning ingredients going.

It works as a thermogenic. This means it heats the body on the inside, causing it to burn fat to cool itself down again.

The catechins in Green Tea are particularly beneficial. They act as antioxidants and help to fight against disease. With help for weight management as well, they are great for all round fat burning. back this notion by saying they are anti-obesity and anti-diabetic which makes this ingredient even more impressive.

WebMD says that it is a milder stimulant than Caffeine Anhydrous and contains just 2-4% Caffeine. The added focus and alertness are just two things you gain from this.

The 500 mg in Instant Knockout is a big and optimal amount that will really work.


Another proven fat burner.

It is a dietary fiber that acts as an appetite suppressant. It works because it absorbs water and swells in the stomach. This makes you feel full and means and therefore less likely to reach for a snack in between meals.

The 500 mg is yet another big and optimal dosage that will really help.


Another effective nutrient.

WebMD advise that Chromium can decrease LDL (bad cholesterol) levels in people who have lower blood fat levels.

There are even studies that have shown it to be able to communicate with the brain to tell the it that the body is full. So, already we have two appetites suppressants making it an excellent start from Instant Knockout.

The 100 mcg is a good amount.

Cayenne Powder

More natural fat burners that work.

Cayenne Pepper is great because it works in more ways than one. It is another thermogenic so you will be burning even more fat as you rest.

WebMD advise that Cayenne Pepper is also good for appetite suppression. They say that it has been found to curve appetite, especially in those who do not already eat spicy foods.

A supplement is a great way of getting the benefits without enduring the heat.

The 100 mg is another effective dosage.

Green Coffee Bean Extract

Another proven ingredient.

Essentially, Green Coffee Extract is just coffee before the color has been roasted out and before a lot of the chlorogenic acid has been as well.

This acid is what we after here as it prevents the body from storing as much fat and keeps blood sugar levels down.

WebMD discusses one study that looked into adults with obesity found that taking Green Coffee Extract for between 8 to 12 weeks resulted in more weight loss for those when compared to others taking a placebo.

With 100 mg you are getting a dosage.

Vitamin B6

B6 is going to be put to good use as it works like many of the B-vitamins to help the body to make energy from food.

It converts food into glucose so it can then be used for energy. At 5 mg we have another good top up.


Another ingredient that will stop us from storing as much fat but also a mood enhancer according to

The 10 mg is another great dosage.

Performix SST


Basically, this is Vitamin B3 and you will see it more and more often in fat burners.

This is because it is a useful addition to a supplement as it can help with insulin levels. Like other B-vitamins, B3 has a role to play in how we create energy. It helps to break down carbs to use them for fuel. advise that you need around a gram of it for it to be effective. The 10 mg included here is well short of that.


You are more likely to find this in a nootropic because of its usual benefits but it makes its way into supplements that contain a lot of stimulants.

It helps the user to cope with the effects of anxiety and leaves you feeling relaxed.

Without reducing the effectiveness of the stimulants, it can help you to feel in control when they start to take effect.

Ashwagandha is believed to also be able to increase physical output so it does have some good traits to offer.

The dosage is needed really to see if it can be effective. The proprietary blend is already starting to cause problems.

Bitter Orange

The second stimulant but the first controversial ingredient.

The safety concerns around Bitter Orange or Synephrine as it is also known should not be ignored.

A banned substance in various sporting organizations the likelihood of side effects is increased when consumed alongside Caffeine (as it is in this product).

WebMD comment that it can be unsafe when taken as a weight loss supplement.

They also go on to say that the potential side effects include dizziness, burning, stinging, blurred vision, drowsiness and more.

One to stay clear of. If you are the subject of testing from your sporting organization we advise that you check before you take any product that contains this ingredient.

This product also contains Synephrine HCI. This makes it even worse. The HCI stands for hydrochloride which is a way of making it water-soluble and easily absorbed.

A worrying element is that we don’t have the dosage either.

Huperzine A

Another ingredient that is better suited to a nootropic.

Again it increases alertness and helps the user to focus, all cognitive boosters are decent inclusions.

The problem really is that for every stimulant they include, they have to also make sure they add a calming ingredient to counter the effects.

Added focus is always a good thing and it can increase muscle strength according to some sources. Still, what we are after is proven fat burning ingredients. Huperzine does protect the brain by helping to break down neurotransmitters.

Given the level of stimulants, this might be very useful. With potential links to fat loss, it could be better than it sounds, but this is based on potential.

Yohimbine HCI

Another controversial inclusion.

It does have some fat burning benefits, appetites suppression and being able to speed up the way we burn fat are just two of them.

The problem is around its safety.

WebMD tells us that when taken orally, it is possibly unsafe. They go on to say that Yohimbine has links to reports of severe side effects that include heart attacks and seizures.

Because it is actually illegal to sell the man-made yohimbine hydrochloride version in the USA as a dietary supplement it is one to keep an eye out for.

Without the dosage, it is hard to say if the user can be assured of their safety.

Other potential side effects of Yohimbe include irritability, sleep issues, and irregular heartbeat.

Mucuna Pruriens

Another common supplement ingredient, just not for fat burners.

It is an ingredient suited to T Boosters because it can reduce estrogen levels.

There do not appear to be any benefits from supplementing it for fat loss making it a pointless inclusion.

Conjugated Linoleic Acid

Made from dairy products, it is essentially just a group of chemicals that have links to fighting diseases. Some sources have shown how CLA has been used to treat obesity so it just might be a useful ingredient.

WebMD tell us that it is a safe ingredient and advise that it can aid fat loss. This does come under their ‘possibly effective for’ area meaning that more research is needed to prove its uses further.

One of the better ingredients in this product, at least it is safe to consume.

Medium Chain Triglycerides

This ingredient is also found in their nootropic supplement and is found in Coconut Oil.

There are loose studies that suggest it could help to boost cognition.

Some dispute this though.

Instant Knockout vs Performix SST Side Effects

It is easy to say that Instant Knockout is safe because of the natural ingredients and sensible yet effective dosages.

The same can’t be said for Performix SST though.

Yohimbine and Synephrine (or Bitter Orange) are two that come with potential side effects.

Without knowing the Caffeine dosage, this also puts you at risk of potential side effects.

For Bitter Orange, these include dizziness, burning, stinging, blurred vision, drowsiness and more.

Also, heart attacks, seizures, irritability, sleep issues and irregular heartbeat from Yohimbine.

Then there is anxiety, insomnia, jitters, high blood pressure, irritability, upset stomach from consuming too much Caffeine.

Of course, they may be dosed low enough to be fine, but we cannot guarantee this.
