if your not a serious trainer then yes any old protein shake is better than nothing but dont be fooled by thinking its al the same cos its not if you drink a shitty protien drink from the lights of nutrisport you will not put on the kind of wieght you want.a protien supplement is just that you use it to supplement you food intake its al down to to calories and getting the right ones so if you eat shit calories you will put the wrong type of wieght on and the same goes for your protien powder dont even bother if your going to take a shit supplement when youve got a choice for something better.
