no its not muscle milk.. ive tried all kinds of muscle milk and I have to say Ive found something better... HDT Problend 55 vanilla... by itself it kinda is boring.. but I add about 30g of dextrose and about 5 frozen strawberries.. this tastes even better than muscle milk's strawberry IMHO.. also its more protein and a cheaper price.. i may try isomatrix next and see how that is...
