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.

My all time favorite protein. The blend is perfect for building more lean muscle and it keeps me fairly full after workouts. The vanilla peanut butter flavor is incredible.

I ordered Vanilla Peanut Butter Swirl due to the high ratings, but it does not have a good taste, probably the worst compared to other flavors. Smores is 10/10 is the best flavor.

When the Tahitian Vanilla Bean flavor first came out I bought it and absolutely loved it. Can easily say it was the absolute best vanilla protein shake I have ever tried and believe me I've prob tried them all. Tasted almost exactly like a vanilla milkshake from the ice cream truck. Tried it again very recently and something is definitely OFF. Not saying it's bad; on the contrary, it's still pretty good (hence the 8 rating) but the first time I tried it it was an absolute 10 out of 10. The vanilla flavor is now a little more generic. Has Jym changed the formula?? Chocolate cookie crunch was also fantastic back then; hopefully it hasn't changed as well

Tahitian Vanilla Bean is by far the best flavor I've had. I had high hopes for the Vanilla Peanut Butter Swirl but not a fan of it mixed in a shake (I used milk). I do think it would be great for baking though.

No joke this taste like a ice cream milk shake with reeces peanut butter cups and oreo cookies. I always feel nauseous after having protein shakes because of their off-flavours, but this one goes right down like a god ol milkshake

Rocky Road and Smores are two of THE BEST protein powders I've ever tried. I like that it's a mix of whey and casein too. I'm not sure about all the hype on the vanilla peanut butter swirl. To me, it does taste like those two flavors but it has this vitamin taste to it that I can't overlook. It messes it up for me. Can't wait to try some of the other flavors like Cookie Crunch and Tahitian Vanilla Bean!

Hands down the best tasting protein I’ve tried. If you like the taste of Nutter Butter cookies, you’ll love this. I have to have my shakes very cold and this powder dissolves with ease in very cold water. Typical Jym product!!
