JYM Mass Gainer Protein Powder


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.
