    The formulation of Method Mass has been designed for gym users and field athletes who need that bit of help with weight/mass gain. Method Mass provides a high-calorie formula in the form of a milkshake style of drink, containing high levels of carbohydrates, calories and whey protein per serving. Β  We believe a ratio of 4:1 carbohydrates to protein is a sufficient amount for a weight-gaining shake. Within this carefully formulated product, there were a few key factors we aimed to accomplish. Convenience was a key factor for Method Mass, and our aim was to create a product that was highly soluble, instantiated once mixed and easy to consume. Taste was also a major factor, like most of our products we eagerly explored the area of flavour technology aiming to deliver that "refreshing milkshake" style of drink where our customers are eager to drink something that is nutritious and of benefit for muscle building and muscle recovery. Consuming Method Mass in between solid food meals will help keep your body in a positive nitrogen balance and support muscle building/weight gain We did not create this product on the basis for the consumer to replace a solid meal but as a product to be used alongside solid meals, such as in between solid meals. immediately after a meal, or pre & post-workout. The Method Mass Serving offers 55g of whey protein. 210g of carbohydrates and 1236 calories we are sure Method Mass can help you along your journey of muscle building.
