JYM SS8 Fat Burner Review – Does It Work?

Here’s a fact: most sequels are terrible.

Jurassic Park… The Star Wars sequels (and prequels?)… Princess Bride 2…?

Hey, that’s because most sequels fail to build upon the strong original content, offering us very little in the way of new ideas.

And when supplement companies release sequels to their own products, it usually doesn’t bode well either. It likely means they’ve had an ingredient flagged up and needed to change the formula.

Occasionally, though, we get a supplement company who develop a new version of a product simply because they believe they’ve created a better, more effective version.

(It’s the supplement industry equivalent of, say, Terminator 2, or Aliens)

And that’s precisely what Jim Stoppani claims to have done with his new product, SS8.

Super Shredded 8 (SS8 for short) is the brand new fat burner from Jym Supplement Science, and today it’s going to be put through my deliberately harsh supplement rating system to determine whether it truly is, as it claims to be, the best fat burner in the supplement industry bar none.

Are you ready for my official Jym SS8 review? Then let’s do it…

SS8 Is The First New JYM Product In 5 Years?!

Jym SS8 fat burner

Jim Stoppani changed the supplement game forever when he launched JYM Supplement Science back in 2014.

There were already a few companies using fully dosed, non-proprietary blends in their products at the time, but Jym did it on such a massive stage that it made the whole industry sit up and take notice.

Of course, nowadays it’s the done thing, and that shows the impact it had.

Also, the fact that Dr. Jim Stoppani has mostly used full clinical doses in his products means that, unlike many competitors, he’s never really had to alter his original line-up of supplements since day one, barring a very minor change to his Pre JYM pre-workout back in 2017.

Super Shredded 8 actually marks the first major update we’ve ever seen to a Jym product.

Jim originally stated that this product would run alongside his original fat burner, Shred JYM, but one look at the ingredients shows it’s designed to eventually replace it.

The JYM SS8 Fat Burner Review


Check out the formula above.

That’s what’s inside the new fat burner from Jym.

Check out this video of the doc explaining the formula, and then I’ll cut through the details…

In this video, Jim claims that that one of the main fat loss benefits to using SS8 is the increased calorie burn you’ll experience.

Unfortunately, this is largely bulls**t.

Sure, caffeine does have an effect on net calorie burn, but we’re talking about a minuscule effect. Relying on it as your key factor in weight loss would be very silly indeed – studies clearly show that the increase in calorie burn is nowhere near significant enough to be a defining marker in weight loss, and this slight increase in net calorie burn also depends entirely on the user being caffeine naive.

(Meaning once you adapt, you lose it anyway.)

The main long-term benefits to caffeine are the improvements it has on focus and energy, not weight loss / calorie burn. (1, 2, 3, 4, 5, 6)

The same rings true for another SS8 ingredient – green tea extract.

You know, 555mg is a decent sized dose of green tea extract, but science shows us that it definitely doesn’t deserve it’s reputation as a so-called “fat burner” (despite the fact it’s included in every pill on the market!). (7, 8, 9)

There’s also much talk regarding the positive effects the green tea extract found in SS8 will have on metabolism, leading to weight loss. However, a comprehensive 2009 study published in the European Journal of Clinical Nutrition expertly showed that green tea has absolutely no effect on resting metabolic rate. (10)

Green tea does have health benefits, for sure, but it’s not a fat burner.

It’s also cheap as f**k, but I’ll get to that later…

JYM SS8 – Ingredient Breakdown

Jim Stoppani SS8 fat burner

Many of you who read my supplement reviews say this is your favorite part of each article, so enjoy.

This is where I quickly run through all the main ingredients inside Super Shredded 8 and let you know if they actually do anything at all.

300mg Caffeine

I love caffeine.

It’s great for boosting energy output, mental focus, and has a very slight effect on calorie burn. There are also strength training benefits to be had, too, but they require a very large dose of 400mg. (6, 1, 11, 12, 13, 14, 15)

The SS8 fat burner includes 300mg of ZumXR caffeine, as opposed to the commonly used caffeine anhydrous. This alternate form of caffeine is preferred for its extended release of energy, similar to TeaCrine. (16)

zumxr caffeine

That means SS8 won’t give you an instant caffeine kick, but will instead spread that 300mg dose out for up to 8 hours.

ZumXR is a nice alternative to regular caffeine, but TeaCrine remains king. (17, 18,19)

500mg L-Tyrosine

I’m a huge fan of this ingredient.

That’s because it works as a precursor to dopamine, meaning we can train harder. (25)

The combination of l-tyrosine and caffeine here will work for Super Shredded 8 in much the same way they work for the awesome AML Pre Workout, albeit the doses are much smaller here.

400mcg Chromium

Chromium is fat becoming a major player in the fat burner world.

That’s thanks to its links with appetite suppression and specifically a reduction in carbohydrate cravings. And despite sounding too good to be true, the link is genuine. (20)

But there are three very important things to remember with chromium…

Number 1 – if you don’t have a chromium deficiency, you’ll see absolutely no benefits from supplementing with it.

Number 2 – if you do have a deficiency, a clinical daily dose is actually 1000mcg.

Number 3 – despite marketing claims that chromium has an effect on glucose metabolism, the experts at confirm it does not.

1.5g Acetyl-L-Carnitine HCL

If you’ve ever used fat burner capsules before, you’ll already know about Acetyl-L-Carnitine.

This ingredient was the fat burner of choice back in 1985, and has continued to thrive in the supplement industry despite being debunked in the 90’s. (21)

ALCAR does have a slight effect on fatigue, so could work as a “fat burner” by allowing the trainee to train a little harder, but the difference is small and we’re clutching at straws. (22)

Nowadays, it’s typically added to pre workout drinks due to it’s cognitive benefits, and we’d require a dose of 630mg-2500mg to see those. Jym SS8 falls right in the “sweet spot” between the two, so you’ll unlock those benefits for sure. (23)

555mg Green Tea Extract

Green tea extract does NOT speed up your metabolism.

There. I said it.

There are studies which literally prove this, I’ve shown you them already, but supplement companies continue to push green tea extract as a “fat burner” due to the myth that it somehow has an effect on our metabolic rate.

It does not.

50mg Cayenne Pepper

Speaking of nonsense… I bring you cayenne pepper.

Spicy foods are often labelled as fat burners for their ability to increase the thermic effect of food, but we’d need to consume a crazy amount in order to create a noticeable spike.

5mg AdrenaJYM

This is the doc’s own patented form of yohimbine.

It contains 4.5g regular yohimbine, and 0.5g alpha yohimbine.

Some people find yohimbine to be a sensitive ingredient to begin with, so the addition of a slightly more potent form may be enough to make you unleash holy hell in your bathroom. In terms of fat mass, improvements have only been shown in doses of 0.2mg per kg body weight (18mg for a 200lb person), but we’re only seeing 5mg here. It’s also an aphrodisiac, so, err, yeah, there is that. (25, 26)


ss8 fat burner vs jym shred

I won’t review SS8 without comparing it to Shred JYM…

Heck, any Jym users reading this are likely wondering what the difference is between the two?

If you take a look above, you can see that Jym’s new Super Shredded 8 fat burner is basically a charged up version of Shred Jym.

Many of the ingredients are the same, with a few new additions.

The form of caffeine has been changed (as mentioned above) and increased from 200mg to 300mg, green tea extract increases from 500mg in Shred Jym to 555mg in SS8 (has the exact same dose of “active” compounds, though), and synephrine is removed entirely, and we have the inclusion of AdrenaJYM.

Oh, and then there’s the new price…

Shred Jym (still available here, btw) costs around $30 for a 40 serving supply. Meanwhile, the all-new SS8 will set you back $60 for a 30 serving supply.

Jim told one Facebook commenter that the big difference in price comes down to the extra quality of the advanced ingredients in SS8, and the fact that it was created exclusively to get results alongside his popular Super Shredded 8 workout program.

I’m a big fan of this particular program, it’s fun to do.

But please don’t be fooled that a fat burner is what’s getting you results with that.

If you see results with it, it’s because you’re performing a LOT of cardio and the accompanying diet has you drop your food intake by about 700 calories per day from start to finish.

JYM SS8 Fat Burner – The Final Verdict!

ss8 fat burner review

It’s the moment you’ve been waiting for.

The first new JYM product in years, how will it fare in my deliberately harsh supplement rating system?

We’ve seen popular products swallowed whole by this thing, it takes no prisoners, and consider anything above 3 stars to be a great sign…

… Jym SS8 earns 2 stars.

And here’s why…

First off, it’s definitely not worth the price (see above).

And second, fat burners in general just don’t work. It’s the one section of the fitness world which has been thoroughly debunked yet people continue to fall for it year after year. Any links to weight loss are very, very weak and the overriding factor in your success comes down to calories in versus calories out, not a pill.

That being said, the ingredients in SS8 are high quality and are definitely a cut above any other fat burner pill on the market, so it achieves its job of being “the best” of a bad bunch.

Is that a compliment for SS8? I guess. It’s kinda like being the best Twilight movie.
