Pro Jym Review: Is Jim Stoppani’s Protein Blend Better than Whey?

Pro Jym is part of the supplement line formulated by Dr. Jim Stoppani, who aside from having a Ph.D. in cellular and molecular biology, has edited popular bodybuilding magazines such as Muscle & Fitness, and FLEX.

He created Pro Jym based on scientific research that shows while whey alone is useful, it is not enough to maximize muscle growth or training adaptations. After hearing good things about the formula, we decided to give it a try for ourselves.

In our straight-talking Pro Jym review, you will soon find out how it faired across the whole supplement spectrum. We talk taste, ingredients, and benefits, to tell you all there is to know.

Pro Jym Nutrition Facts

Pro Jym operates on the "blends are best" motto, containing 3 types of protein which in order of dose are whey, casein, and egg white. As I'll explain in just a minute, there are actually 4 protein sources if you include milk protein isolate, which seems to confuse people for some reason.

Pro Jym is a little higher in calories than other supplements, but not by much. Making up the 150 calorie total are some carbs (6 g) and a few grams of fat (4 g), of which there is only 1 g of sugar and 0.5 g of saturated fat, making it a pretty lean formula.

There's a remarkable 32% of the RDI for calcium, as well as smaller amounts of sodium and potassium, which are minerals, and is no surprise given it's a whey and casein blend.

Making up the rest of the ingredient label are sweeteners (sucralose and acesulfame potassium), which are typical of supplements in this category, sunflower lecithin, which is used to aid mixability, and cellulose gum which is naturally found in some plants, and is used as a thickening agent to give Pro Jym a creamier taste.

Pro Jym Ingredients

There are 4 types of protein listed on the front of the tub, but when you break it down, there are really only 3 primary sources. Let's start with the type that seems to cause people the most confusion.

Milk Protein Isolate (7 g)

Much like fresh milk, it has a ratio of around 80% casein and 20% whey. The difference is, unlike the liquid you buy at the grocery store, milk protein isolate is filtered to remove the lactose, which creates a leaner, purer protein source.

On average, it has less than 3% fat, over 90% protein, and can be suitable for those who are lactose intolerant.

Whey Isolate (7.5 g)

Typically, WPI has a protein concentration of around 90%. Unlike whey concentrate, whey isolate is processed to separate the protein from the fats and carbs, which includes lactose, and cholesterol to some extent.

Because no pesky fats and carbs are lining up to be digested, whey isolate is absorbed rapidly, and damaged muscles can repair sooner. Now, if only there were a slow digesting protein source to complement it…

Micellar Casein (7 g)

Unlike whey isolate, the protein molecules in casein are digested really slowly. It's the perfect addition to pro Jym because as the best effects of whey begin to wear off, the most significant benefits of casein are only just kicking in.

It is typically taken before bed but can be used any time of the day to prolong protein synthesis, which means you don't need to slam down a shake every 2-3 hours.

Egg White (2.5 g)

Often called "egg albumen," egg whites are one of the most bioavailable protein sources in existence, and with no lactose, can be consumed by those who don't tolerate or enjoy dairy.

Who Can Benefit From Taking It?

Anyone seeking to add more protein to their diet, or supplement their fitness regime, can benefit from taking Pro Jym regularly. Being a non-amino spiked powder, you can drink it in the knowledge that you are getting only high-quality protein and no unnecessary fillers.

However, those who will enjoy Pro Jym the most, are those seeking more muscle growth, and those who do not fancy buying whey and casein separately.

After training, our muscles are screaming for amino acids, and whey protein can do a decent job at supplying the demand. The best effects of whey peak very early, and after a few hours, our muscles are one again, aching for amino acids.

But by adding casein into the mix, we effectively ‘drip feed' our muscles with a steady supply of amino acids, which elevates the anabolic state for longer, and can lead to more muscle growth.

How To Properly Use

  • Add between 6-12 oz of either cold water or milk of your choice into your shaker cup.
  • For 2 servings, double the liquid.
  • Add in a scoop of Pro Jym and shake well.
  • Drink and enjoy

When To Take Pro Jym

The directions recommend taking 1-2 scoops at a time. Jym Supplement Science advise taking it in the morning and before bed, as well as pre and post workout if you want to maximize muscle growth.

We agree that these are all excellent times to use the supplement. However, based on its blend of whey and casein, we believe that taking it post-workout and before bed, is the best choice. Why?

Before bed, and after training, you are in the peak of the anabolic window, which is the period where your muscles are most receptive to amino acids. If you trained the day before, you may well still be in the anabolic window by the time pre-workout roles around.

However, you will enjoy the best effects of the anabolic window in the hours immediately following the training, which are post-workout and before going to sleep. Protein is not as useful when your muscles are not stimulated.

Sizes, Servings, And Scoop

It is available in two different sizes, which are each suited towards lower and higher budgets, but also how often you use protein powder.

  • 2 pounds (23 servings)
  • 4 pounds (46 servings)

Each serving consists of one scoop which weighs 39 g and is quite large in size compared to other protein shakes that we’ve tried.

Pro Jym Flavors And Taste

In total, there are 9 flavors to choose from, some of which like "Gingerbread Cookie," isn't your typical protein shake flavor. We were torn between Chocolate Mousse and Tahitian Vanilla Bean, but being chocoholics, we plumped for the Mousse option.

Here's what we thought:

It's a very thick shake compared to some others we've tried. Even with plain water, there was no funky aftertaste, and the consistency was very smooth. Having a natural sweet tooth, I, Bernie, went ahead and mixed it with almond milk first which really intensified the creaminess.

I drank it with regular milk later, but being so thick, I ended up using around 12-14 oz, which might be a problem calorie-wise for some people. If I used 2 scoops, then my shaker bottle would be filled to the brim with milk, which although delicious, would be calorically expensive.

Overall Review

This is an excellent supplement in many ways. Helping people grow more muscle they otherwise would, and just generally increasing their quality protein intake, we rate Pro Jym highly among the best in the business.

The combination of whey, casein, and egg whites deliver a rapid, yet sustained release of amino acids to the muscles. Having 3 types of highly bioavailable proteins, Jym Supplement Science removes the need to buy separate batches of whey and casein.

With one scoop, your muscles will reap the rewards of both fast, and slow-digesting proteins.

Ideally taken post-workout and before bed, Pro Jym keeps amino acid levels topped up, with a creamy formula that can help to prevent muscle catabolism. If you are serious about building muscle or recovering faster, then go ahead and give Pro Jym a try to see how this unique approach to protein can benefit you.

We hope you enjoyed our Pro Jym review. Hopefully, it helped you decide which brand to add to your stack.
