anyone use Isopure Protien. I know this is a bit redundant but I am trying different kinds and not sure what to get. Was recomened Isopure. I am not looking for weight gainer. Just protien to feed the muscle. I have lost about 50 pounds and really cut up. Now I feel due to diet I am starting to lose muscle so I really want to up my protien to about 300 grms per day food and shake. Any help would be appreciated. Also was looking into pro blend 55. Thanks. I am not a big fan of the way protien tastes and It has to be thin for me to be able to drink so no thick shakes.
