Pro JYM™

Building Muscle Never Tasted So Good!

To make improvements in the gym, high-quality protein powder should be on the top of your shopping list. When designed properly, protein powder is truly a triple-threat – it can be used to get bigger, stronger, and leaner.* Plus, it's fuel – food that feeds hungry muscles, while also satisfying the occasional (or regular) sweet tooth, not to mention replacing snack foods that can derail your progress.

Blends Are Best

Pro JYM's three types are absorbed in the body at varying rates – whey extremely fast, casein very slowly, and egg at a “medium” pace. This is exactly how you want your protein to act to ensure that the muscles get an immediate supply of amino acids (the building blocks of protein) as well as a steady trickle of them in the hours following.*

Research now shows that when you add medium-digesting and slow-digesting proteins to fast-digesting whey, muscle protein synthesis remains elevated for longer than when using whey alone.* And muscle protein retention is higher, as well. That means that more protein is being built in the muscle, which is what leads to long term gains in muscle size and strength.*

Pro JYM Digestion Timeframe

Pro JYM Feeds Your Muscles Longer

Pro JYM's exclusive protein blend extends the process of building, repairing and retaining lean muscle well beyond that of Whey Protein Isolate.* As shown in chart 2 above, Pro JYM harnesses the fast-acting benefits of Whey Isolate (red line) and then extends these benefits up to 3-hours longer with micellar casein (green), and egg (blue). It's the protein that works as hard as you do.

All-Day Protein Source

Before and after workouts are two great times to take Pro JYM, but your body needs high-quality proteins throughout the day to repair and build muscle. The fast-digesting whey in Pro JYM makes it a great first-thing-in-the-morning protein source to help stop catabolism, and the slow casein is ideal to take before bedtime to provide the muscles amino acids while you sleep.* Pro JYM also functions well as a snack or as an addition to any meal that needs a protein boost.

Build and Recover*

It takes ample protein to build new muscle and gain strength and recover after hard workouts* – plain and simple. Getting all that protein from whole foods would be a quite a chore, but Pro JYM makes it easy... and delicious!

Best-Tasting Protein You Ever Had

You can't underestimate taste and texture when it comes to your protein. Seriously, if you're going to have multiple protein shakes every day, don't you want it to taste great?! With Pro JYM, just as much attention is paid to flavor as the protein blend formula. I want to mix my protein in water or milk and have it literally taste like a milkshake – and Pro JYM does! With amazing flavors like Chocolate Cookie Crunch, Rocky Road, Chocolate Peanut Butter, and Tahitian Vanilla Bean – plus a thicker, creamier texture than whey-only powders – you'll look forward to your Pro JYM shake every day!

No Proprietary Blends

A proprietary blend is any supplement that doesn't list the precise dose of every single active ingredient it contains. This isn't only prevalent with pre-workouts and fat-burners – a vast majority of protein powders on the market are proprietary blends as well because they don't tell you the exact amounts of proteins in the formula. Pro JYM, on the other hand, lists the exact amounts on the front of the container of all three types of proteins in their four distinct forms: whey protein isolate (7.5 grams), micellar casein (7 grams), egg albumen (2.5 grams) and milk protein isolate (7 grams = 5.5 grams casein + 1.5 grams whey).

No Protein Spiking

Nitrogen spiking (aka “amino spiking” or “protein spiking”) is an unscrupulous and widespread technique that allows some supplement companies to put in less protein than what's listed on the label (without getting caught) as a means of slashing costs and increasing their profit margins – at the user's expense. Getting a “spiked” protein means paying for, say, 24 grams of protein but getting only 18 grams of actual whole proteins. With Pro JYM, you get all 24 grams per serving, guaranteed. Pro JYM has and never will be spiked with cheap fillers.

Complete The JYM System With Pro JYM

Pre JYM and Post JYM (BCAAs+ Recovery Matrix) take care of all the individual amino acids and other performance- and recovery-boosting nutrients you need around workouts.* With Pro JYM, you're getting complete proteins to help fuel the muscles and maximize recovery.* Take Pro JYM along with both Pre JYM before workouts and Post JYM afterward.

No BS, Just Science

I've been studying nutrition and supplement science both in the lab and in the gym for decades. I've done the research, and I've converted it into real results for millions of real people just like yourself. I began educating hard-training men and women worldwide through the pages of Muscle & Fitness, FLEX, and Muscle & Fitness Hers magazines before finding a home for my programs, articles, and videos here on, as well as my own website I created Pro JYM because I was fed up with seeing nothing but whey-only protein powders. Now consumers have an ideal protein blend to maximize gains in size, strength, and even fat loss.*

Tasteful and no much sugar. Fast digesting without problem. Egg protein% is very low. For muscle gains, there are better brands.

I’ve tried most of the big name brands and ProJym is definitely my favorite. It’s not Isolate so you are getting some carbs and fats here but you’ll absolutely love the taste. I can’t remember the last time I actually had a S’mores, so I can’t really speak to how close it resembles that flavor...but what I can say is that is by far the best tasting “chocolate based” dessert-like flavor I have ever tried. There is no vitamin after taste at all like some proteins have. And it really satisfies the sweet tooth. There definitely is a subtle Graham cracker vibe and I really dig the little marsh mellows. I’ve also mixed it with some kodiak cakes pancake mix and the pancakes turned out good. I highly recommend it. I take 2 servings per with breakfast and one with the post workout meal..,or I’ll save it for a night time snack on rest days. But be’ll definitely want more than 2 servings a day. It’s that good!

Whey protein usually upsets my stomach but this is such high quality stuff, I have no problems with it. Only Jym Stoppani could make plain vanilla my favorite flavor. It tasted just like vanilla bean ice cream. So good and such high quality protein.

Honestly, JYM products are excellent and I am a huge fan. But, whoever formulated "Chocolate Cookie Crunch" should be relieved of their duties effective immediately. This goes for the "Vanilla peanut butter swirl" as well.

Great tasting protein powder that mixes well with water, oat milk, almond milk, you name it. I drink a shakeinthe morning mixedwith my black coffee and oat milk and you have a tasty and nutritious way to break your morning fast. Post-workout (around 930pm) I mix it with my oatmilk to keep me satisfied throughout the night. Excellent protein powder that I can only give my highest recommendation!

Yum!! This flavor is delicious and has small crunchy chunks in it, which I thought I wouldn’t like but I do. I mix it with 12 oz of Unsweetened almond milk and it shake it up. I use it for a snack and post workout, I even make protein coffee with it sometimes. I can’t wait to try other flavors. :)

I am Stoppani disciple -- use pre and post jym with this protein and get great results from all three. I am a member of his site and regularly rotate my programs with his workout programs with, again, great results. My beef, however, and reason for the 7 rating can be summed up in the words "Acesulfame and Sucralose." That stuff messes with the food cravings center of the brain. I realize it is in most bodybuilding supps except for a line of Optimum Nutrition natural products, but if you are having trouble managing your hunger cravings then those two artificial sweeteners may be the culprit. There is also anecdotal evidence for other bad things that artificial sweeteners may be responsible for. C'mon, Doc, you are a man of science. You have to be aware of that. Natural sugar in low amounts or stevia is probably way better for you health wise. So, yeah, basically, I am lobbying you, Doctor Stoppani, to clean up the formula with a different sweetener. .
