Jym Mass Jym
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.
Each serving of Mass JYM provides:
- 30g Protein (15 grams casein, 12 grams whey, 3 grams egg protein)
- 30g Carbs (15 grams low-glycemic index (GI), 5 grams high-GI)
- Nearly 5 grams of fat (1.3 grams saturated fat, 1.3 grams monounsaturated fat, 1.3 grams
- Polyunsaturated fat, including 1 gram of CLA)
Mass JYM Protein Blend
Designed to the exact specifications as my award winning Pro JYM protein – each serving of Mass JYM delivers 30 grams of the highest-quality protein powder blend available. Mass JYM delivers 50% casein from micellar casein and milk protein isolate; 40% whey protein from cold-filtered whey protein isolate and milk protein isolate; and 10% egg white protein.
This protein blend provides just enough fast-digesting whey to quickly spike muscle protein synthesis, plus adequate amounts of slow-digesting casein to keep protein synthesis elevated for several hours after ingestion. Egg white protein provides a medium-digesting protein source that also provides higher levels of sulfur-containing amino acids as compared to dairy protein.*
Research studies show that a protein blend providing more slow-digesting casein than fast-acting whey and a medium-digesting protein elevates muscle protein synthesis longer and leads to greater net protein balance than whey protein alone [1, 2].* Simply put, a protein blend is more anabolic than whey on its own.*
Mass JYM Carb Blend
Each serving of Mass JYM 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.*
Mass JYM’s ratio of low-glycemic (low-GI) to high-glycemic (high-GI) carbs is another key aspect that makes this formula a true lean-mass-gainer. I designed the carb blend in Mass JYM mainly from pea starch, isomaltulose, and oat fiber to deliver a 3:1 ratio of low-GI to high-GI carbs.
At this ratio, you won’t spike insulin (outside of a normal range) or add fat as easily as you would with a mass-gainer that uses primarily high-GI carbs like sugar, dextrose, or maltodextrin [3, 4]. It also means Mass JYM works well as a pre-workout carb source, as it provides a small amount of quick fuel followed by a larger amount of long-lasting fuel [5, 6] to help provide energy from the start of your workout all the way to the end. Research further shows that when consuming carbs before and/or during workouts, the body’s testosterone-to-cortisol ratio is higher, suggesting the body is in a more anabolic state.
Another way carbs are essential to maximizing muscle growth has to do with muscle cell volume. Glycogen, the storage form of carbohydrates in muscle, pulls water into muscle cells. The higher the muscle glycogen content, the fuller (bigger) the muscle will be. Yet maximal muscle cell volume has more to do than just looking bigger – it also places a stretch on the muscle cell membrane that can help signal biochemical pathways leading to an increase in muscle protein synthesis, which can lead to long-term increases in muscle growth.
