Pro JYM Review – True King Of All Protein Powders?

Share for Russ:

As a kid, I remember watching Kane appear in the WWE.

pro jym review

He was monstrously big. He was scarier than his on-screen brother, The Undertaker. And he dominated everything in his way.

Child me was gobsmacked.

And in many respects, Pro JYM is the whey protein version of Kane.

It smashed its competitors into the ground with no mercy, rising through the ranks of the supplement industry faster than anything which had came before it, and became the world’s #1 best-selling protein supplement.

But in today’s Pro Jym review, it faces its toughest challenge to date – my awesomely harsh supplement rating system!

No product has every received 5 stars (this may be the first?), and no product can claim to be truly great until it has faced the unholy a**-kicking I’m about to lay down on Pro Jym to determine whether it really is the true king of whey protein powders…

Let’s get to work!

The Strange Story Of Pro Jym…


My reviews are known for being unbiased and in-depth – I know you guys appreciate that side of them – and I can’t review Pro Jym without going into the backstory behind this popular muscle builder.

When Jim Stoppani launched his product line in 2013, he changed the game.

With high quality ingredients and transparent labels, JYM was a brand you’d happily expect to pay extra for and it instantly ranked among the industry top dogs, like Optimum Nutrition.

One of the driving factors behind this was the Doc’s reputation as a good source of information for all things supplement-related. He featured regularly in Muscle & Fitness magazine, pointing out which ingredients should (and shouldn’t) be in certain products to maximize results in the gym.

Heck, at that time I’d probably have let him bang my girlfriend if he’d said it would improve my barbell squat.

So it made perfect sense when the mighty partnered with Jim Stoppani to create his own supplement line: Jym Supplement Science.

It was the perfect storm, and three months later Pre JYM was released. A great first product, you can read my review here, this pre workout set the standard that other brands are still trying to beat years later.

But shortly after the release of Pro JYM the following year, things started to get very messy for Jym Supplement Science…

First, it was suggested in an article over at PricePlow that Dr. Jim Stoppani didn’t even formulate Pro Jym, and that had simply repackaged their own store-brand whey protein drink and bumped the price up.

That sounds ridiculous, until you take a look at the labels for Pro JYM versus the now-discontinued Protogen:

Pro Jym vs Protogen
“Strange, right? It’s like someone took the Protogen formula, dropped the doses, and bumped the price up to create Pro JYM…” – PricePlow

What follows next is the Doc’s own massive case of “foot in mouth” syndrome.

When Pro JYM was released, it was billed as the world’s only whey protein supplement which doesn’t use a proprietary blend.

Dr. Stoppani has been very keen to point this out on a number of occasions, too:

“When I tell people that Pro JYM is the only non-proprietary protein powder blend available today, some state that a few other companies are already doing what I am doing.

But they’re not.

A few other companies are listing the percent of each type of protein that is in their protein blend. For example, a protein powder blend that is whey, casein, and egg protein might list that it’s comprised of 40% whey, 40% casein, and 20% egg protein…

… but that is NOT listing the exact amount of each one of those proteins!

Pro JYM is the ONLY protein powder blend that lets you know EXACTLY how much of each type of protein you are getting in every serving. If your protein powder blend is NOT Pro Jym, then it’s a proprietary blend!”

Where do I start with this?

There is so much wrong here, it could have been said by Gwyneth Paltrow.

First of all, take a look at the nutrition label for Pro JYM itself:

pro jym review

I’ve seen worse proprietary blends, sure, but this is still one.

Also, there are definitely companies out there who do not use proprietary blends. Jim is talking absolute s**t here.

NutraBio is one such company.

They’ve been around since 1996 and have been releasing high quality products with no proprietary blends at all. When one of Jim’s “fans” pulled him up on this on Facebook, he released this silly video doubling down on his belief that Pro Jym is the only product without a proprietary blend and claimed that nobody cares if smaller companies are doing it anyway, because they don’t matter.

It resulted in one of the most beautiful pieces of YouTube history, when well-respected NutraBio founder Mark Glazier responded with this absolutely devastating comeback blow:

(Warning: If you watch this video, you’ll want to buy NutraBio, not JYM.)

As if we needed things to get any crazier, Jim and then had a huge public disagreement about who the “owner” of Jym Supplement Science is, and Dr. Stoppani switched his entire product line over to GNC stores.

This disagreement lasted nearly 18 months, before JYM once again returned to and now you’re up to speed!


As you can see, despite the huge success of this line-up, it’s been a bumpy ride so far for JYM!

I hope the craziness above made for some interesting reading.

Now let’s take a look at the product which claims to be the world’s best whey protein supplement, to determine whether it really is the TRUE KING.

Pro Jym gives us a nutrition breakdown of:

  • 24g protein
  • 7g carbohydrates
  • 3g fat

The actual amount of protein in each scoop is great.

A 2009 trial published in the American Journal of Clinical Nutrition found that a serving size of 20 grams of protein created almost as much of an anabolic spike as a serving size of 40 grams, so with Pro JYM coming in at 24g per shake, it’s definitely in the right ballpark. (1)

But one issue which presents itself here is the protein-per-serving ratio.

You’re buying a whey protein supplement because you want more protein in your diet, yes? And I’m always telling you guys to look for a protein which offers you at least 75% protein-per-serving, because that means most of your scoop is the thing you are looking for – not bulls**t sugar or filler ingredients.

Given that the scoop here is 40 grams, and 24g of it is protein, that means Pro Jym has a PPS ratio of just 69%.

For such an expensive shake, that’s LOW AS F**K.

In fact, it’s one of the lowest I’ve ever reviewed!

But perhaps I can cut Dr. Stoppani a little slack here, though.

Sure, there are 7g carbohydrates and 3g fat in each scoop, and I consider these quite high for a product which calls itself an “Ultra Premium Protein Blend”, but that still only equals 34 grams total. Jym Supplement Science have added a s**tload of thickeners and sweeteners to Pro Jym to give it a nice taste.

It’s unnecessary, and it lowers the protein-per-serving ratio.

But it makes the product taste nicer, and that’s why it’s such a big seller.

When we look at the type of protein used, things begin to pick up again. Pro JYM contains a protein blend of whey protein isolate, casein, and egg. This is very solid, I’m a fan of this approach. It means Pro JYM will provide a slow and steady release of amino acids for your muscles to feed on, rather than the instant hit of whey itself.

Also, notice there is no whey protein concentrate in Pro JYM.

I don’t really mind whey protein concentrate (WPC), but if you’ve ever had lactose issues, you’ll appreciate this move.

This switch cements Pro JYM as a “premium” protein powder, because whey protein concentrate is cheaper to formulate and companies will often use it for over 90% of their “blend”. Pro Jym excludes it entirely, focusing on whey protein isolate instead.

(Hey, it’s also worth knowing that we could avoid any lactose issues from WPC by simply switching to a higher grade version of it, such as WPC80.)

Anyway, why am I a fan of Pro Jym using a blend?

I’m forever telling you guys to ditch protein powders that only provide one source of protein (i.e. whey concentrate, or whey isolate) in favor of those which offer multiple sources due to their timed release explained above. This has been shown to be more effective for muscle growth in studies versus whey alone, and these results are simply too easy to grab we don’t need to leave them on the table. (2, 3)

Pro JYM Review – The Final Verdict


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

As my Pro JYM review comes to an end, I’ve got to give you guys a final verdict and cast the dreaded score upon it…

Pro JYM won’t dominate the whey protein industry in the way that Pre JYM dominated the pre workout market.

That’s because Pre JYM was ahead of its competitors (at the time), but Pro JYM isn’t.

Not to stir the pot, but NutraBio Muscle Matrix provides a superior formula with a higher protein-per-serving ratio and less carbohydrates per scoop (yes, that NutraBio!).

That being said, Pro JYM is still a solid supplement. When I compiled my end-of-year list of the top 5 whey protein supplements, Pro Jym came in 4th spot.

Dr. Jim Stoppani has created a nice blend of fast, slow, and slower release protein which is great for building muscle and tastes like a f**king milkshake.

I’m not gonna fault that.

It receives a solid 3 star rating from me.
