- ISOLATE BLEND – Scientific studies have shown that a blend is considerably better for maximizing muscle-build than standard whey protein alone, this blend contains whey protein isolate, micellar casein, milk protein isolate, and egg white protein.
- 1:1 RATIO – This super mass gainer has a patent pending fat blend that delivers 30 grams of carbs and 30 grams protein blend for lean steady gains. It's the worlds first true "lean mass" gainer developed by Dr. Jim Stoppani.
- LEAN MUSCLE GROWTH – Mass JYM contains real macros for lean muscle growth: 15 grams casein, 12 grams whey, 3 grams egg protein. For both men & women, this blend supports your natural strength, energy, endurance & recovery during muscle weight gain.
- GREAT TASTE – No other protein powder surpasses the great taste, texture, and nutrition of Pro JYM. Simply mix with water, milk, almond milk or add other ingredients for a delicious high protein shake or smoothie. It also comes in vanilla.
- VERSATILE USE – The mass powder is great for a meal supplement when on the go or as a serious mass gainer. The blend of fast, medium and slow digesting proteins elevates muscle protein synthesis for longer and supports rebuild.

About JYM Supplement Science
Founded in 2013 by renowned sports nutrition and supplement expert Jim Stoppani, PhD, the JYM brand is based on real science, the highest quality ingredients and, above all else, full transparency.
JYM transformed the supplement industry by educating consumers on questionable marketing and manufacturing tactics like protein spiking, proprietary blends and ‘concentrated’ formulas.
The Science of Mass JYM
Mass JYM formula is the first mass-gainer to use a non-proprietary protein blend (Pro JYM) along with a non-proprietary low-glycemic carbohydrate source, and a non-proprietary healthy fat source. Unlike like most mass-gainers that include twice as many carbs as protein, Mass JYM contains a 1:1 ratio of anabolic protein to low-GI carbs for “clean” gains.
It takes all three macronutrients working in harmony to truly maximize muscle size. Mass JYM delivers the most anabolic protein blend, quality carbohydrates, and healthy fats to promote lean growth. Use Mass JYM as a post-workout shake and/or a snack between meals.
Mass JYM’s specific protein blend of 50% casein, 40% whey, and 10% egg white (same as Pro JYM) elevates muscle protein synthesis for longer periods and is more anabolic than whey protein on its own. As a result, your muscles will recover better, and grow bigger, after hard workouts.
Fat is a critical macronutrient for increasing muscle strength and size. Mass JYM’s 1:1:1 ratio of saturated to monounsaturated to polyunsaturated fats – including 1 gram of the omega-6 fat conjugated linoleic acid (CLA) – will help you optimize testosterone levels and grow bigger and stronger.

About the Mass JYM Protein Powder: Supported Goals: Muscle Growth – Strength – Energy – Endurance – Recovery – Refuel. Mass JYM is a revolutionary mass-gain formula that has taken years to perfect. It’s the first of its kind, a true non-proprietary mass-gainer that fully discloses the specific types of protein, carbohydrates, and fat contained so that you know exactly how much of each macronutrient you’re consuming. It’s not enough to know just the total amount of protein, carbs, and fat that a mass-gainer provides – you need to know the precise amounts of each type of protein, each type of carb, and each type of fat. Otherwise, you won’t know if it’s a lean-mass-builder or just another “fat-gainer” made of cheap protein concentrate and sugar. I essentially designed Mass JYM to be Pro JYM plus an equal amount of carbs – primarily low-glycemic and the perfect (and patent-pending) fat blend. Designed to the exact specifications as our award-winning Pro JYM protein – each serving of Mass JYM delivers 30 grams of the highest-quality protein powder blend available. Each serving of Mass JYM also contains 30 grams of carbohydrates to deliver a 1:1 ratio of protein to carbs. This is critical. Consume too many carbs, and you’ll gain body fat in addition to muscle.* Take in too few carbs, and you won’t optimize muscle growth.*The 1:1 ratio of protein to carbs helps keep the gains lean and steady.
