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.

Smores Projym is probably the best tasting protein I've ever had. Jim turned the industry on it's head with transparent labels a few years back, so I trust this stuff. Carmel macchiato is my second favorite, then chocolate cookie crunch.

I like Jim and his stuff..BUT...if you look at this scoop size per gram(40) and yet there are only 24 grams of protein, that tells me there is a TON of other 'stuff' vs pure protein..that is enough to make me a bit weary of this product...good tasting

I'm mixed on this product as the flavor is 10/10 for me (I drink it with milk and it makes it like a creamy root beer float flavor) and I like the macros, BUT it has ingredients known to California to cause cancer (Prop 65). This seems not to matter to most people but it matters to me so I will not be buying this product ever again.

I struggle to find a protein shake with a consistency and taste I can tolerate and I’m highly impressed with Jym. It keeps me fuller longer and I love the taste. Disclaimer: I do mix with milk for a better taste. I do have to shake it up and let it sit for a couple minutes so the consistency to even out, but that may also be due to the milk. The little marshmallows in the s’mores are probably my favorite part. It makes me feel like I’m drinking something more indulgent than a protein shake.

With out a doubt the best protein I have tasted. Mix’s very easy no weird after taste. Recommend trying it with milk and and sparkling mineral water tastes great. Like root beer float and vanilla egg cream. Love both but root beer slightly edges out vanilla

Love Jim's proteins, and that he has a lot of different flavor options to choose from. I like keeping 2 tubs at the same time and switching up when I feel like something different. Some of the flavors are even good enough to have as an evening dessert!

All I can say, is look up Prop 65. Check the warning label on this product. I won't be supporting Jym any longer

Chalk. That's all I taste. Definitely the chalkiest protein I've ever had. No chocolate taste, just crunchy pebbles and chalky liquid. Second worst protein I've ever tasted behind whey cake doughnut.

Best protein I've ever tried, I will say you need more then one scoop to get the thick strong flavor that the old formula had. But still amazing flavors no upset stomach

I bought this for a before-bedtime casein protein shake. The flavor is really good; I mix it with milk, a tablespoon of unrefined coconut oil and some Gaspari glutamine. It mixes well and literally tastes like a vanilla shake. I highly recommend this product.

I kind of have a feeling that jym 2.0 isn't that anabolic anymore also post jym. While i used the old post jym also as a pre workout because i could not handle the caffeine in pre jym. I always had a extreme pump but now i'm not even close to that. Also the taste of vanilla is dry kind of without love but a good point is that it does not cause disgusting mouth odor like jym 1.0 and also post jym 1.0. Or the reason for all that is that i ate a lot of bread and pasta in the last months and it inhibits the gut to absorb the amino acids properly.

I love Jym, but stay away from the Chocolate Mousse flavor. It tastes good but is the worst mixing protein I have ever had, has chunks that will not go away. I will keep buying Jym, but this flavor was a waste of my money.
