Medicis Fast Weight Gainer Medicis Fast Weight Gainer contains a balanced and effective blend of high quality protein, vitamins and minerals, carbohydrates and fats, which can be consumed by both men and women for healthy weight gain. Weight gainers are suitable for ectomorphic (lean) type individuals who have low body fat, but have problems with weight gain due to fast metabolism. Compared to normal food, the composition is energetic and, depending on the formulation, consists primarily of a small proportion of carbohydrates and proteins as well as fats, vitamins, and trace elements. The excess energy is partially stored as glycogen, partly as neutral fat. The high energy content can be measured individually, the preparation of high energy lifters leads to increased buildup of fat tissue during regular consumption.
