Emperor Mass 2500 g YAMAMOTO
Emperor MASS is Yamamoto Nutrition’s one-of-a-kind mass gainer, packed with perfectly balanced macro- and micronutrients and containing nearly 40% protein per serving. It’s theperfect solution for supporting muscle growth and maintenance, providing a substantial 520 kcal per serving, yet remainseasily digestible thanks to the addition of a specialized enzyme blend.
The protein blend used in Emperor MASS consists exclusively ofhigh-quality proteins: whey protein concentrate, whey protein isolate (produced via ultrafiltration and microfiltration), and calcium caseinate, to ensure both an immediate release of amino acids into the bloodstream (thanks to the whey proteins) and a gradual release (thanks to the calcium caseinate).
Another keyfeature ofEmperor MASSis itshigh content offree-form, instantly solublebranched-chain amino acids(BCAAs): each serving provides a full 4.8 g of BCAAs in the optimal 4:1:1 ratio, with a higher proportion of leucine to support protein synthesis and help counteract muscle catabolism after intense workouts.
The formula also contains 4.5 g ofglutamine, a conditionally essential amino acid that improves post-workout recovery, counteracts catabolism, supports muscle growth, influences nitrogen balance (reducing protein “loss”), improves immune function, and reduces intestinal permeability and inflammation, exerting a positive effect on the gut microbiota.
Another distinctive feature of Emperor MASS isits highcontent of lipids from the highest-quality sources. It containsMCT oils(medium-chain triglycerides) andflaxseed oilpowder(fromLinum usitatissimumL. seeds). MCT triglycerides supportcardiovascular health andwell-being, while flaxseeds are added to help maintain healthy levels ofblood pressure,cholesterol, andbloodglucose. They are a natural source of omega-3 fatty acids with anti-inflammatory and antioxidant properties.
Emperor MASS is alsolow in sugar: the carbohydrate component of the product consists solely ofDE6 maltodextrin, a polysaccharide derived from starch that is easily digestible and absorbable, which the body can take in without risking gastrointestinal upset. Carbohydrates are extremely important for health and muscle growth because they help replenishmuscle glycogen storesandserve as theprimary energy source for muscles.
Despite its low sugar content, Emperor MASS provides over4 g of fiberperserving, derived primarily fromFOS(fructo-oligosaccharides). FOS are soluble fibers withprebiotic properties, capable of selectively stimulating the growth of certain bacteria in the colon, positively altering the balance between “good” and “bad” microorganisms and thereby supporting gut health. These compounds also function as intestinal regulators, as digestive support in cases of dyspepsia, and as an aid in the treatment of hypertriglyceridemia and hypercholesterolemia.
The formula is rounded out by a complexblend of enzymes that support digestion and nutrient absorption, consisting of amylase, protease, glucoamylase, lipase, cellulase, lactase, pectinase, and papain (fromCarica papaya L.). This blend makes Emperor MASS an easily digestible product despite its high calorie content, and suitable for consumption at various times of the day.
Due to its high protein and amino acid content, Emperor MASS cannot simply be called a mass gainer; rather, it is a product with unique properties that is ideal for all athletes and sports enthusiasts seeking a supplement that offers a perfectly balanced mix of macronutrients and includes all essential sources.

Our recommendation:We recommendtaking Emperor MASS especially during bulking phases. With 520 kcal per serving, 41 g of protein, 60 g of carbohydrates, and very little sugar, it’s ideal for getting all the nutrients essential for muscle growth and maintenance, without causing digestive discomfort or strain. It can be taken mid-morning, mid-afternoon, or as needed, and is also useful post-workout.
Doubts Common
Can I use Emperor MASS as a pre-workout supplement?No, we do not recommend doing so: Emperor MASS is a mass gainer—a product designed to support muscle growth that is rich in calories and nutrients. For this reason, it is not suitable as a pre-workout supplement.
Can I prepare Emperor MASS in the morning and drink it a few hours later?No, we always recommend that you prepare your Emperor MASS right before drinking it. Its formula is very complex and sophisticated, and since it contains various substances derived from plant fermentation, the flavor may change if left in solution for too long without being consumed.
I have celiac disease. Can I still take Emperor MASS?Yes, every batch is tested for gluten to ensure it is always completely gluten-free.
I’m a vegetarian—can I still take Emperor MASS?Yes, this product is suitable for vegetarians. However, it is not suitable for vegans, as the protein blend used is derived from cow’s milk.
