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.*

The flavor and mixability are impressive. The combination of egg, whey; casein protein is interesting; and likely beneficial for muscle development. The overall ingredients, including mini-marshmallows, lowers my rating a bit.

One of the best tasting proteins! I love cookies, so the Chocolate Cookie Crunch flavor hits the spot. This protein also blends well without adding volume to my smoothies. --BBcom Employee

Best testing quality protein I’ve ever had and I’ve tried a lot. 8-9 years of training in the gym consistently and I can tell you these products are quality and effective at building muscle and strength. Take advantage and buy them while they’re on sale, they are rarely marked down.

I am rating this as 7 because of what it is, this will be the last time I trust American reviews on flavours, absolutely disgusting, gritty, like drinking weetabix with sugar cubes, now I'm stuck with 1.8kg worth of powder. It's fine, I can suck it up, but you guys have too low standards if you think this flavour deserves to have the most stars, I dont even want to know how awful are the rest of them.

I've been using this for a little over a week now and I'm loving it! I'm starting to feel great while using it to get some extra protein everyday and the flavor is excellent. Chocolate Mousse tastes like an actual milkshake when used with milk and with water you get a chocolate milk-like flavor.

I’m not sure what I am doing wrong with this stuff, but it does not mix worth a dang, at least compared to my Gold Standard. It doesn’t matter if I mix it with water, milk, use a blender bottles, or a blender, it doesn’t mix. My workout alone could be just mixing this stuff. Even in my blender, after I run it, there is protein mix stuck to the side of the blender. It turns into a paste. It has good flavor, but the little chunks don’t really help. I don’t get it. I was excited to try this but I was disappointed. I guess I’m glad it works for others.

Great product. Buy far the best tasting protein I have ever had. The vanilla is the first vanilla protein that I have had a actually tastes like vanilla. The Rocky road is my favorite so far. I just wish you could buy it in larger amounts like a 10 pound bag.

When will the vanilla peanut butter swirl be available again? It's the best one in my opinion. Can't wait to buy it again

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