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:

Protein chart
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.

The old formula was great. The remake....not so much. Very chalky, doesn't mix well at all.

Don’t be fooled by the Stoppani lemmings who were asked to come on to BB and write highly favorable reviews. Do you really believe there is legitimacy in someone rating nine separate flavors 10 out of 10? Dig through these reviews and you will see the reality - somewhere around the end of last year/beginning of last year, the formula on this product was changed. What had been the best tasting protein on the market took a significant nose dive in terms of the flavor. But what’s the real issue with this? There has been no public admission of the reason for this, no explanation why, or if anything is being done about it. I can easily handle that it was done to improve the profitability. But when there is no explanation at all, and continuing pretensious tales of the flavor being better than ever, that creates a real loss of credibility and trust. What is being hidden here? Customers can handle change as long as there is transparency as to why the change and what the future direction is. That has been conspicuously missing throughout this.

Man this protein is so good. It's super clean, fills you up as a meal replacement and mixes really well. My favorite is by far the Chocolate Cookie Crunch and S'mores. I also purchased the Tahitian Vanilla Bean and if the Cookie Crunch and S'mores didn't exist, then the Vanilla would be my favorite. Low carbs, low calories, 24g or protein, its a solid protein mix.

I’ve been using Jym products for about 2.5 years on and off. Some of the flavors I love some I can’t. I do have to say that I have seen great results since I’ve been using the jym system. I started out at 230 with 27% bf now I’m 204 with 14% and never felt better. I’ve done triathlons, 5ks and other sporting events. I’m really glad the legacy flavors came back except I think the s’mores tasted better before. I think it’s missing the graham cracker flavor now.

***DONT BE A SUCKER*** This protein has gotten so much worst (not just taste) over time. I used to use ProJym religiously several time a day, now each sip irritates my stomach. What did they do!?!?!! NOW they are asking peopl from their Facebook group (which they dont allow and questioning or constructive criticism or u get deleted) e to come here and leave “authentic reviews” what a freakin joke. Try to join the “Jym Army” Facebook page and you’ll see. They make u take a test to just join the page, then if u write anything that can be interpreted as criticism, your post will not get approved by the moderator and you will eventually get deleted from the group. But back to the protein..... OWN u messed it up and freaking FiX it!!! Or there will no longer be a “army” to have your back in the future

I've taken all kinds of protein but have always came back to JYM products. Am I an expert? No, I'm not but I know what I like and I've been taking supplements for about 18 years now. Make sure you watch your nutrients and your ingredients. Take what you want but for me and my family we will continue taking what we feel is the best for us.
