JYM MASS JYM
JYM supplements combine scientific research with premium ingredients at precise doses to bring you the best possible results. Mass JYM is the ultimate lean mass gainer. With both a 1 scoop and 2 scoop serving, you can customize Mass JYM to fit your personal fitness goals or diet requirements. Combining only premium protein sources and a complex carbohydrate blend, Mass JYM is made for one thing: building serious size.*
Unlike most mass gainers on the market, you won’t find low-quality concentrate protein or cheap maltodextrin in Mass JYM, only the highest-quality ingredients that produce incredible results.*
What You Get with Mass JYM
30 grams of protein from quality sources. No concentrate protein.
30 grams of carbohydrates from a combination of Pea Starch, Polydextrose, Isomaltulose, Oat Fiber, and Dextrose. No maltodextrin.
Complete transparency. You see the exact gram amount of each protein and carbohydrate source.
Free from Concentrates
Protein is paramount. When shopping for an effective mass gainer, don’t make the mistake of simply looking at overall calories and total protein—there’s a whole lot more that goes into an effective gainer.
If Mass JYM’s protein blend looks familiar, that’s because the same combination of protein sources used in Pro JYM protein powder is in Mass JYM. Each scoop provides 30 grams of protein from high-quality whey protein isolate, micellar casein, milk protein isolate, and egg white protein. We skip the whey protein concentrate, which you’ll find in just about every other mass gainer on the market. Don’t sacrifice quality for calories. You can get both with Mass JYM.*
Egg albumin: 3g • Micellar casein: 9g • Milk protein isolate: 9g (7.2g casein, 1.8g whey) • Whey protein isolate: 9g
Are Blends Best?
This is a hotly debated topic within the fitness and nutrition community: Which is more effective for muscle growth and recovery, a protein blend or whey alone? While whey protein is crucial for muscle growth, whey protein alone may be coming up short. A well-engineered blend of premium proteins will help maximize muscle growth.*
Whey is a rapidly digesting protein that results in a quick spike in muscle protein synthesis (MPS), which is exactly what you need post workout. However, this quick spike lasts a short amount of time due to the quick-digesting nature of whey proteins.
Adding medium-digesting and slow-digesting proteins to whey results in an increase in MPS for a longer period of time than whey alone. Muscle protein synthesis is directly responsible for muscle growth and an increase in muscle size, so increasing your body’s anabolic response over a longer period of time can seriously impact your overall results.*
1:1 Carbs to Protein Ratio
Carbs are crucial when you’re trying to put on mass and load up on quality calories, which is why they’re a key part of Mass JYM’s ultimate lean-mass gainer formula.*
Just like protein, there’s more to the carbohydrates in a mass gainer than just the gram count. You want a specific blend of carb sources that digest at a consistent rate to avoid a rapid rise and fall in blood sugar.* The best way to assess the blood sugar impact of carbohydrates is with the Glycemic Index.
The Glycemic Index, or GI, measures carbohydrates based on how they raise blood glucose. These carbohydrate sources are ranked in comparison to reference foods. Glucose and white bread, both with a value of 100, are at the upper end of the GI spectrum. The lower the GI value of a food, the slower its carbohydrates are broken down and released as glucose into the bloodstream. Foods with a lower GI value have a positive impact on your body’s insulin sensitivity, which is a crucial component of how your body utilizes protein and carbohydrates.
There is a time and place for both high-GI and low-GI carbohydrate sources. A perfect example is the dextrose used in Post JYM Carb. Post-workout dextrose spikes blood sugar to help replace the glycogen your body just used to fuel your workout and enhances the uptake of creatine and carnitine, which you will find in Post JYM Active Matrix(link).* A mass gainer requires a precise combination of fast- and slow-digesting carbohydrate sources that will work at any time of day.*
Mass JYM can be taken in the morning, between meals, post workout, before bed, or whenever you can fit in a shake to help you hit your macronutrient targets.
Beat the Bloat
The key carbohydrate component of Mass JYM is pea starch, a very low-GI carbohydrate. It produces a steady rise in blood sugar and a correspondingly steady insulin response.* Best of all, pea starch has a very low osmolality. Osmolality refers to the concentration of solutes in a given solution, such as a protein and carbohydrate shake. A shake with a high osmolality won’t diffuse properly through the membranes of your digestive system, causing serious bloating, a very common problem with mass gainers. Pea starch is also a source of prebiotic fiber, which helps increase beneficial intestinal flora.
Dextose (3g) • Creamer/Flavor System (5.5g)
Pea Starch(14.5g) • Polydextrose(4g) • Isomaltulose(2g) • Oat Fiber(.25g)
Rounding out the carbohydrate blend in Mass JYM are dextrose, polydextrose, isomaltulose, and oat fiber. Mass JYM provides your body with both quick-digesting carbs for immediate utilization and high-quality complex carbohydrates to extend elevated blood glucose and insulin levels for optimal recovery.* You’ll find the amount of each carbohydrate source listed below along with a chart showing the ratio of low- to high-glycemic carbs, making Mass JYM the most transparent gainer on the market today. These low- and high-glycemic values were established according to the guidelines set by the American Diabetes Association, which considers a GI value of 55 or less low-glycemic, and a GI value of 70 or more high-glycemic.
Raising the Bar
Most mass gainers list the ingredient maltodextrin first or second. Maltodextrin is an extremely cheap carbohydrate source that is also very sweet and helps make a mass gainer taste good. Maltodextrin is considered a complex carbohydrate due to its chemical structure, which allows companies to list little to no sugar on the product label.* Sound too good to be true? It is.
Maltodextrin breaks down extremely quickly in the body and has a glycemic index rating higher than sugar--it’s a whopping 105! This is actually off the charts since glucose is the gold standard value of the glycemic index at 100. Some of the most popular mass gainers sold today have in excess of 100 grams of maltodextrin in one serving. This can be devastating to your digestive system and energy levels, not to mention the potential digestive irritation that can come from such a giant serving size of a low grade carbohydrate.*
Safe from Protein Spiking
The protein content listed on the back of the Mass JYM bottle is exactly what you will get in each scoop. We never add cheap amino acids to falsely inflate our products’ protein content, a process known as nitrogen spiking or amino spiking. Many of these added amino acids are advertised as beneficial. Though many of these ingredients are beneficial, it’s at the expense of grams of protein you think you’re paying for.
Make it Your Own
Mass JYM was strategically flavored to match the taste profile of Pro JYM, not only because Pro JYM is by far the best-tasting protein powder available, but also to make Mass JYM extremely versatile. Looking to make Mass JYM more protein-heavy? Try combining one scoop of Mass JYM with 1 scoop of Pro JYM. You’ll have a hefty dose of 54 grams of protein with 35-38 grams of carbohydrates.
Have a favorite Pro JYM pancake or baking recipe? Try swapping out Pro JYM with Mass JYM when you need a few extra calories. Since Mass JYM is roughly double the serving size, you’ll want to double all other ingredients as well. You’re welcome!
