Performix Iridium SSTi Review – Bloated Prop Blend…With Rosemary?!

Iridium SSTi









  • Over-stretched prop blend
  • Contains blatant fillers
  • Rosemary? SERIOUSLY?!


Full Performix Iridium SSTi Review


Performix is one of the biggest sports supplements brands on the market right now. Most major supplement retailers stock their supplements, and they run their own independent online store. They have an enormous range of products; they make everything from whey protein powders and pre-workouts to cognitive enhancers and multivitamins.

Their products have some of the most confusing names on the market, too. It’s really hard to figure out what each product does just by looking at the name. Their Iridium range, for example, includes SSTi, IONi, and so on. This might impress some people, but we’d prefer it if things were more straightforward!

So what is Iridium SSTi all about?

What does it do?

Who is it designed for?


Performix Iridium SSTi Review


If you look at the box, you’ll see that you’re promised three big things if you use this fat burner:

  • Ballistic body energy
  • Accelerated fat metabolism
  • Cognitive priming

More and more fat burners are providing some kind of cognitive-enhancing component. This makes a lot of sense; dieting cripples your ability to focus and think clearly. This is true both in and out of the gym. You don’t want to find yourself zoning out during an important meeting or losing track of your sets in the gym because you’re tired and hungry.

Increased energy levels and accelerated fat metabolism are two absolute must-haves for any fat burner nowadays.

So this looks like a really great fat burner…if all of this is true, that is.

Does Performix Iridium SSTi really do all of this stuff?

Is it safe? Will it cause side effects? What about long term risks?

How does it compare to our current top rated fat burners? Is it a good purchase?

Find out by reading our detailed Performix Iridium SSTi review below. We work our way through all of these questions, giving you as much useful information as possible. If you have any more questions at the end of the review, then let us know in the comments.


Iridium SSTi Formula

Check out the Performix Iridium SSTi ingredients list, as it appears on the label:


Performix Iridium SSTi formula


That does not look like a very appealing product to us!

We have one, big, bloated proprietary blend here. Performix might have divided it into three sections on the label, but that doesn’t mean anything. All of these ingredients are lumped together in the same capsule, and we have no idea how most of them are dosed.

All we know is that the total serving size is 1,151mg. We’re given the serving size for caffeine, but that’s it.

This is a real problem. There are more than a dozen other ingredients in this fat burner.

There are some great ingredients, and some obvious ‘filler’ candidates.

Overall, this is not a good fat loss supplement. We think it represents poor value for money, as well as posing significant side effect risks. 


Main Problem – Proprietary Blend

We absolutely hate proprietary blends.

They are never justifiable.

There is no good reason for any manufacturer to hide their formula specs behind a prop blend. They often claim that they need to do this to prevent anybody else from stealing their formula.

But in our experience, this NEVER happens. 

There are countless supplements out there which show each ingredient’s serving size on the label. Nobody steals those formulas. The manufacturers make millions of dollars a year.

If anything, the best supplements use their ingredient doses as a major selling point – they don’t stop talking about it!



Iridium SSTi major issue - proprietary blend


If they can do it, then everybody else can too.

So why do people use proprietary blends?

We think there are only two possible explanations.

One explanation is that they are naive and genuinely scared. This doesn’t matter to us of course. As consumers, it’s not our job to feel sorry and make allowances for manufacturers. It’s not our job to wonder why they can’t compete. If they can’t offer the transparency offered by other supplements, then we’re obviously not going to buy their product. Simple.

Another explanation is that they are trying to hide the fact that their formula is stuffed full of cheap ‘bulking’ or ‘filler’ ingredients. We think this is most often the case where proprietary blends are concerned. Most manufacturers know that nobody is going to steal their formula. They know that the ingredients they’re using are all well understood and widely used; there’s never any special secret to steal. They just don’t want us to know that the best ingredients are all under-dosed.

This is why all proprietary blends are to be avoided. Other supplements are happy to tell us the individual ingredient doses. Why would we opt for anything else?!


Major Problem – Blend Over-Stretched

The Performix Iridium SSTi proprietary blend has some really specific problems.

A major problem is the fact that the blend is seriously over-stretched.

The blend is 1,151mg in size.

It comprises 15 ingredients in total.

That gives us an average serving size of 76mg.

However, we know that the caffeine is dosed at 200mg.

This gives us 951mg split between 14 ingredients, which means we have an average serving size of 67mg. 

This doesn’t mean that every single ingredient is dosed at 67mg.

It means that, for any ingredient dosed over 67mg, another ingredient has to be dosed below 67mg.

Does that sound like a reasonable dose to you?

Do you think 67mg of Ashwagandha is going to do anything when the typical dose is over 300mg?

Do you think 67mg of Citicoline is going to do anything when it is typically consumed in amounts in excess of 200mg?

Either some of these ingredients take up 70% of the formula, or they may as well not be here at all.


Major Issue – Obvious ‘Fillers’

A major red flag for us when looking at a prop blend is the use of cheap ingredients that don’t do the things stated on the bottle. These are almost always acting as ‘fillers’ – bulking out the formula so the manufacturer can skimp on the exciting (and expensive) ingredients.

We see a prime candidate in Performix Iridium SSTi: Rosemary.


rosemary Iridium SSTi ingredients


We have no reason to think that rosemary helps with fat loss.

We’ve never read a study which found that rosemary has a noticeable, meaningful effect on lipolysis, muscle retention, appetite, or anything else for that matter.

The label lists all of the amazing compounds that the Performix rosemary extract contains. But we don’t see why these substances should be added to a supplement designed to accelerate fat loss.

We think it’s possible that rosemary has only been added to bulk out the formula. This would allow the manufacturer to cut back on the more expensive ingredients. It doesn’t add anything to the stack; it doesn’t help you achieve the goals written on the bottle. Why else is it here?!

Iridium SSTi Side Effects – Is It Safe?

Performix is a very reputable company. They care about their brand, so it’s clear that they aren’t going to risk serious hurting their customers for the sake of a fast buck. 

That said, there are some serious side effect concerns presented by this product. 

The main risk factor, in our opinion, is the caffeine content. Each serving of Iridium SSTi contains 200mg of caffeine anhydrous. This is about the equivalent of 2 large, fresh brewed black coffees. For some users, this will be fine so long as you aren’t already consuming a lot of caffeine throughout the day anyway. For others, it will cause side effects.

Common side effects of caffeine consumption include, but are not limited to:

  • Anxiety
  • Hypertension
  • Irritability
  • Jitters
  • Dizziness
  • Headaches
  • Sweating
  • Shaking
  • Energy crash
  • Insomnia

You need to think carefully about how much caffeine you’re already consuming before you add in an extra 200mg through supplements. 

We are not doctors, and this is not medical advice. You must do your own research and consult a medical professional before continuing. These supplements are NOT a cure for obesity. They are meant for serious athletes who need help maximizing results during a cut.


Performix Iridium SSTi Review Conclusion – Is It Worth A Try?

In our opinion, not really. 

Any product hiding the formula behind a proprietary blend just wreaks of “scam” to us.

The most successful supplement manufacturers all show their formula in full on the labels. They aren’t being ripped-off left, right and center. The best supplements use their formulas as selling points. If they can do it, then so can everyone.

When someone doesn’t share their individual ingredient serving sizes, then we’re always deeply suspicious. 

The Performix Iridium SSTi proprietary blend has serious problems of its own, but the huge, over-stretched prop blend is enough to put us off.

If you want some decent bang for your buck, not to mention reliable, predictable results, then you’re better off using a more transparent fat burner.
