you can only increase size and mass when your body is in a calorie surplus; therefore, at the end of each day, you must have fed your body more calories than you have burnt. This can be achieved via consuming regular energy-dense meals and snacks that are high in quality protein sources to help build muscle mass and size. Myprotein’s newly formulated Impact Weight Gainer is a convenient choice of supplement for all gym-goers striving to increase mass as it ticks all those important macronutrient boxes!This new formulation now boasts 33g of fast and slowly digested proteins per 100g serving, making it perfect for post-exercise recovery as well as a slow-sustained delivery of proteins throughout the day. On top of this, a combination of oat flour and maltodextrin supply 50g of carbohydrates per serving, which will provide the body with a complex source of carbohydrates. This unique formulation is also a source of fibre to support a healthy balanced diet.
