JYM SS8 Fat Burner Review – Does It Work?

Most sequels are awful.

It’s a fact.

Jurassic Park… Star Wars… Princess Bride… I could go on.

And when supplement companies release sequels to their own products, it usually doesn’t bode well either.

Today I’ll be looking at the latest supplement to try this, as Dr. Jim Stoppani’s new new fat burner SS8 is reviewed and put through my deliberately harsh supplement rating system to determine whether it’s a worthy improvement on the original (Shred JYM).

Super Shredded 8 (SS8) claims to be “the best fat burner the industry has ever seen.” So are we looking at the supplement equivalent of Terminator 2? Or are Jym Supplement Science talking s**t?

We’ll find out in my official Jym SS8 review below.

Jym SS8 fat burner


Jim Stoppani had a massive impact on the supplement industry 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.

Nowadays, every top brand follows a similar model.

The fact that Dr. Jim Stoppani used full clinical doses in most of his products had another benefit. Unlike his competitors, he’s never really had to alter the original line-up of supplements since day one, barring a minor change to his Pre JYM pre-workout in 2017.

Super Shredded 8 actually marks the first major update we’ve ever seen to a JYM product. Upon its release, Jim stated that this product would run alongside his original fat burner, Shred JYM, but one look at the ingredients show it’s designed to eventually replace it.



The formula above shows us exactly 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…

Unfortunately, many of the claims made in this video are bulls**t.

Jim states that that SS8 is such an effective fat burner because it causes a much higher calorie burn caused by the caffeine in the product.

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 is very silly, as studies clearly show that the increase in calorie burn is nowhere near significant enough to be a defining marker in weight loss. This slight increase in net calorie burn also depends on the user being caffeine naive. The main benefits of caffeine supplementation are the improvements it has on focus and energy, not weight loss or calorie burn. (1, 2, 3, 4, 5, 6)

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

By including a massive 555mg in each serving, Jim has gone “all in” with this ingredient. But once again science shows us that green tea extract doesn’t deserve it’s reputation as a so-called “fat burner” (despite the fact it’s included in every pill on the market!). There’s also much talk regarding the positive effects SS8’s green tea extract will have on metabolism, leading to weight loss. However, a comprehensive 2009 study published in the European Journal of Clinical Nutrition showed that green tea has absolutely no effect on resting metabolic rate. (7, 8, 9, 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.

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 go through all the main ingredients inside Super Shredded 8 and let you know what they do, and if the dose is sufficient to see results.

Let’s start with the main one.


I love caffeine. It’s awesome.

It can boost 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 traditional caffeine anhydrous. This alternate form of caffeine is preferred for its extended release of energy, similar to TeaCrine. (16)

That means SS8 won’t give you an instant caffeine kick, but will instead spread that 300mg dose out for up to 8 hours. Interesting, huh? ZumXR is a nice alternative to regular caffeine, but TeaCrine remains king because it has far more research behind it. (17, 18,19)

zumxr caffeine


Here’s another ingredient I love.

This one 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. With more energy and more dopamine, you can train like a Tazmanian devil.


Chromium is the next big trendy ingredient in the fat burner world.

That’s thanks to its links with appetite suppression and specifically a reduction in carbohydrate cravings. This link is genuine, too, despite sounding too good to be true. (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, not 400mcg.
  • Number 3 – despite some claims that chromium can have an effect on glucose metabolism, the experts at confirm it does not.


If you’ve ever used a fat burner 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 thoroughly debunked in the 90’s. (21)

ALCAR (for short) does have a slight effect on fatigue, so could work as a “fat burner” by enabling you to train a little harder, but the difference is so small we’d consider this clutching at straws. (22)

Nowadays, ALCAR is 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” for this, so you’ll unlock those mental focus benefits for sure. (23)


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.



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 see a noticeable spike in results.


This is Dr. Stoppani’s own patented form of yohimbine.

It contains 4.5mg regular yohimbine and 0.5mg alpha yohimbine.

It’s worth knowing that some people find yohimbine to be a sensitive ingredient, so the addition of a slightly more potent form might make you unleash holy hell on the toilet. But in terms of fat loss, improvements have only been shown in doses of 0.2mg per kg body weight. That’s 14mg or a 150lb person, 18mg for a 200lb person, and 22mg for a 250lb person. SS8 only provdes 5mg.

Yohimbine is also an aphrodisiac, so, err, yeah, be prepared. (25, 26)

ss8 fat burner vs jym shred


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

Heck, any JYM fans reading this are likely wondering what the difference is between the two anyway.

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, but there are 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). 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 tub. Meanwhile, the all-new SS8 will set you back $60 for 30 servings.

Welcome to the real world, folks.

When asked about the price hike, Jim told one Facebook commenter that it 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 that program it’s because you’re performing A LOT of cardio and the accompanying low carb diet has you drop your food intake by about 700 calories per day from start to finish.

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

How will the first new JYM product in 5 years fare in my deliberately harsh supplement rating system?

We’ve seen many popular supplements get swallowed whole by this thing, it takes no prisoners, and I consider anything above 3 stars to be a great score.

Take a look below, JYM SS8 gets 2 stars and here’s why…

First off, it’s definitely not worth the inflated price.

And second, fat burners in general just don’t work. They’ve been thoroughly debunked for many years, but 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 will be determined by calories in versus calories out, not a pill.

That being said, the ingredients in SS8 are high quality compared to other fat burners on the market, so it achieves its claim of being “the best” of a bad bunch. Is that a compliment for SS8? I guess, but it’s kinda like being the best Twilight movie.
