Product Overview

Pro JYM. The anabolic protein powder created and used by Dr. Jim Stoppani. High Quality Protein Blend for Maximal Muscle Growth.

"JYM Supplement Science combines real science with best-in-class ingredients and precise doses to deliver unreal results. Pro JYM is my exclusive protein blend designed to help you build muscle, recover faster, and train stronger. Whether you want to boost strength, add size, or get shredded, Pro JYM is for you. It's a powerful blend of proteins that add up to pure muscle fuel."


Grow Like a Pro

Each scoop of Pro JYM delivers 24 grams of pure, quality protein. It’s not "spiked" with single amino acids to artificially increase the protein content or made with cheap and inferior whey protein concentrate or caseinates. To make Pro JYM, I selected only the highest quality whey protein isolate, micellar casein, milk protein isolate, and egg white protein (egg albumin).

The 24 grams of protein in each scoop of Pro JYM contain the following:• Whey protein isolate: 7.5g

  • Whey protein isolate: 7.5g
  • Micellar casein: 7g
  • Egg albumin: 2.5g
  • Milk protein isolate: 7g (5.5g casein, 1.5g whey)

Since milk protein isolate is 20 percent whey protein and 80 percent micellar casein, the 24 grams of protein in Pro JYM are really broken down into three main categories:

A Blend is Best

While a high-quality protein powder should be at the top of everyone's supplement shopping list, don't make the common mistake of buying a pure whey protein powder right off the bat. Yes, whey protein is a critical staple for muscle growth, but to truly maximize growth, you need more than just whey. You need a precise blend of performance proteins.

Whey is a very fast-digesting protein. The rapid rate of digestion is one of whey's benefits, but on its own, this quality can actually be a downfall. Because whey digests so fast, it quickly boosts muscle protein synthesis (MPS). However, it only boosts MPS for a short amount of time.

Research now shows that when you add medium-digesting and slow-digesting proteins to whey, muscle protein synthesis remains elevated for longer than when using whey alone. Since muscle protein synthesis leads to muscle growth, elevating muscle protein synthesis for longer can have a significant impact on your overall gains.

In fact, research suggests that people who add slow-digesting casein protein to a whey protein shake around their workouts enjoy greater muscle growth over time than people taking whey alone. This research is the very reason I recommend taking a blend of fast-digesting whey protein, medium-digesting egg protein, and slow-digesting micellar casein.


Say No to Protein Spiking!

Many supplement manufacturers cut corners on their protein powders because high-quality protein is very expensive to make. They often use a dirty trick called “nitrogen spiking.” Nitrogen spiking, also called “amino spiking” or “protein spiking,” is a way to manipulate the test used to measure the protein content of protein powders.

The current method used to assess the amount of protein in a protein powder involves measuring the nitrogen content, which is then converted into protein amount. Nitrogen is used because protein is made of amino acids strung together in a chain, much like a pearl necklace, and every amino acid contains nitrogen. If manufacturers add loose amino acids to a powder, they can fool the test and deliver less pure protein than their labels claim.

Many people think that extra amino acids in their protein powder are beneficial. The major problem, however, is that certain amino acids are not added to make the protein powder more effective. Instead, they're simply added for their nitrogen. Most single amino acids, such as taurine and glycine, are much cheaper than whey protein, casein protein, milk protein, or egg protein. Even highly beneficial amino acids like BCAAs and glutamine are cheaper than protein powder. So, by adding a bunch of cheaper amino acids to their protein powders, supplement companies can boost their nitrogen content, which technically means they boost the amount of protein per serving, at least according to the nitrogen test.

Because the added amino acids are not complete proteins, the protein content of a spiked protein powder is not truly what a nitrogen test claims it is. For example, a whey protein powder may claim to contain 20 grams of protein per scoop. However, if the manufacturer added 5 grams of glycine per serving, then you are only getting 15 grams of actual whey protein and 5 grams of glycine, which would read as 20 grams of protein per serving.

An even bigger problem arises when proteins are spiked with amino acids that aren't used as building blocks to form proteins in the body. Taurine is once such amino acid. Taurine helps with energy production, so you might first be excited to see a high quantity of it in your protein. However, if 5 grams of taurine has been added to your protein powder that claims to contain 20 grams of protein per serving, you are only getting 15 grams of real protein and 5 grams of taurine. So the extra taurine comes at the expense of total protein.

If your favorite protein powder lists BCAAs, glutamine, beta-alanine, betaine (trimethylglycine), or creatine, you might think it’s a great product because of the additional nutrients. Yes, your protein contains these performance nutrients, but you may be getting them at the expense of the protein, not in addition to the protein. All those ingredients are nitrogen-containing compounds that count towards the total protein amount listed on the label. You might be getting up to 10 grams less protein per serving than listed on the label.

The rampant use of nitrogen spiking is the main reason why I list the precise amount of each protein in every 24 gram serving of Pro JYM. Whey protein isolate makes up 7.5 grams, micellar casein makes up 7 grams, and milk protein isolate makes up 7 grams, and the remaining 2.5 grams comes from egg white protein (egg albumen). That totals 24 grams from complete proteins with no added amino acids or filler nutrients.


The Power of Pro

As with every other supplement in the JYM line, I want you to know the exact ingredients and doses in Pro JYM. I want you to see that it contains nothing but a pure blend of high-quality proteins in the exact amounts needed to maximize growth, recovery, and repair. In short, I want you to grow like a pro.

Prepare to experience the power of real science, real ingredients, and unreal results.

Bring back chocolate cookie crunch. The new Pro JYM is disgusting. I've already started to try and find a new brand. BB.com'S response has unfortunately been basically, "Don't let the door hit you on the way back." Don't buy the new kinds, as that is the only way they will make the business decision to bring back the old flavors.

I started using the Chocolate Cookie Crunch PRO JYM and I loved it! best one ever. Recently I been forced to buy this new line....sadly it doesn't come near close in taste to the old one, reminded me of the 90's protein shake taste (old), still it is a good product in terms of its content (clean) and will do the work.

no more Cookies & Cream???!! No more Chocolate Cookie Crunch??!!!!! I have tried a few of the new flavors (including Tahitian Vanilla Bea, Red Velvet, and Caramel Machiato) and they are not even close to being as good as the "old" flavors: they don't mix well at all and, most importantly, they just don't taste that great - I kept going back to Cookies & Cream and Chocolate Cookie Crunch - I have been a faithful purchaser of Jym products the last few years; I guess it's now time to find a different company to purchase my protein from -

Where is the chocolate cookie crunch????!!!! I’m so disappointed this flavor is no longer available. I guess it’s time to find another protein brand as the other flavors are gross.

BRING IT BACK!! chocolate cookie crunch is the only protein i have found that mixes well, tastes good and works. I have tried the other flavors - the are pale in comparison. the new formula is no bueno compared to the old formula - i think the flavor ratings on the site show this - even the new vanilla - VANILLA! - doesn't even come close to the older flavors..
