Russian Bear 5000 Weight Gainer provides over 2600 calories per serving with over 184 grams of protein, 391 grams of quality glycogen-replenishing carbohydrates and 46 grams of medium chain triglycerides (MCTs). When mixed with a gallon of whole milk, Russian Bear 5000 Weight Gainer provides 5000 calories consisting of 292 grams of protein, 567 grams of carbs, and 128 grams of nutrient dense fat. It’s long been known that whole milk puts on muscle mass faster and more efficiently than any other type of food. Whole milk is rich in both whey and caseins, and so is Russian Bear 5000 Weight Gainer. Vitol suggests mixing 1 full serving of Russian Bear 5000 with 1 gallon of whole milk at the beginning of the day and drinking it steadily throughout, so your body has time to properly assimilate all of the protein and muscle-building nutrients.
