Deliciously flavoured pure whey protein concentrate - our Core Pure Whey Protein delivers all of the essential amino acids necessary for building and maintaining lean muscle mass. A great protein source providing you with an abundance of amino acids (in particular Leucine) which initiate muscle protein synthesis. Whey protein will help to promote muscle tone, ensuring that you are able to maintain your endurance ability and performance. Taking whey proteins along side your training enhances the acute muscle protein synthesis - basically the more you do the better your body becomes at absorbing protein and converting it into muscle mass. If you are overtraining and not fuelling your body with the correct balance of carbohydrates and proteins you may notice a decrease in your muscle mass - daily protein shakes will avoid this and ensure when you are training you are building muscle rather than burning muscle.
