With 1,250 calories per serving to boost daily calorie intake, 50g high protein to support muscle growth and repair, over 250g carbohydrates helping support muscle recovery, and now with 3g added Creatine to support performance per serving, you have got nothing to lose and lots to gain.

Ready to mix the powder with protein, carbohydrates, vitamins and minerals, with sweetener Creatine increases physical performance in successive bursts of short-term, high-intensity exercise. Carbohydrates contribute to the recovery of normal muscle function after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle. This benefit is observed with a total carbohydrates intake of 4 g per kg body weight, at doses, within the first 4-6 hours following exercise.
