There is always going to be arguments over what protein is best etc. Theres alot of them out their! A couple of tips I always give my clients is. Avoid any protein shakes with added sweeteners, this will bulk up the carb and fat count and is going to do nothing for you, sure it might make it taste good, but thats because it will have sugar/sweeteners in to make it that way! Rule of thumb for protein generally is 1 scoop calories should be not much more than 4 x the protein, example: if one scoop is 100 calories then there should be around 25g (give or take 2 grams) of protein in the scoop, if there is much less protein then its more than likely the protein is filled out with carbs. As for the creatine, it has only been proven to cause liver problems with those who don't drink enough water along with it, which is advised with all creatine. PS: If you are looking for protein throughout the day, dont ignore foods such as tuna, chicken, lentils, peanut butter (moderation) as they are also great for you. Most people prefer protein shakes after workouts as in liquid form it can access the muscles faster, thus helping recovery. Sorry if this was a tad boring!
