Product Overview

Best Tasting Supplement of the Year Exclusive Bodybuilding.com Products
pro-jym-bag

High-quality
protein blend
for maximal
muscle growth

JYM combines real science with best-in-class ingredients and precise doses to deliver unreal results.* Pro JYM is our 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

Every scoop of Pro JYM delivers 24 grams of quality protein.

The 24 grams of protein in each scoop of Pro JYM contain the following:

  • 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.*

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.

I had never had a protein that had a mix of casein and whey together but this protein was one of the best tasting proteins I've ever had! After the first few shakes it was thick but I assessed the amount of fluid I needed to get a good mix and I can have no complaints with the results!

I have all the respect in the world for Jim and I am sure his product is technically what it should be but the flavor Smores was awful. I have not used it consistently because the taste is so bad. I see somewhat put down it tastes like graham crackers. I wish it did. It tastes almost burnt to me. I will most likely try another flavor of his. To me, today there is no reason for a bad tasting protein powder.

This review is long overdue. I have been taking projym for months now. I can say this is the best product I have used. I have noticed substantial gains to my physique. It has helped me pack on muscle and helped with recovery. I don't see myself switching to any other product. I just wish is was a bit cheaper.

The mini marshmallows are a nice touch. Tastes more like graham crackers than anything else, but it's still the most delicious protein shake I've ever had. I saw really good improvement in my muscle growth, as well as weight loss, while using this as a meal replacement/supplement.

Not a fan of this product. Does not mix well, even one scoop to 30 oz. of water. Clumps stay suspended and will not mix,even added ice cubes and still clumps and sticks to shaker top. Has a gritty flavor and an almost a chemical taste that is just not right. This is a very cleverly marketed product asking top dollar but let's be real its not worth it if you don't look forward to drinking it. Alot of hype that missed the mark. Reality, I did not feel or notice a single difference using this product after using this protien the way described by Jim Stoppani for months except bubble gut and bad taste left in mouth. Save your money. I went back to BSN mixes easily, blended protein, and everyone knows that the flavors are some of the best.
