Anyone have any experience with being on course and using protien drinks? Ive heard the speal on how the big bulky Mr. Clean built guys with there protien drinks cant perform in the field because there body isnt getting the usual amount of calories as opposed to when ur just going to the gym and all that. But i want to know if it will be harmfull to my health or field performance if I start drinking around one protien drink a day. Im on SQ so i have the 5 day field ex comin up.
