i have been looking into adding a protein supplement into my diet. i am in good shape but have been trying to gain more strength to help in rock climbing which i am just starting to learn. i go to the gym 5 days a week but i dont eat much meat and honesly my diet is not the greatest. i went to the local gnc the other day and was overwhelmed by the choices. the guy behind the counter was really not much help. he went on and on about the most expensive muscle supplement in the store and didnt answer any other questions. so basically my main questions are, can you have to much protein and although this may sound silly is there a difference between the protein supplements made for men vs womens formulas? are there all natural proteins that are just as good as the manufactured ones? any help would be appreciated since the salesman seemed more interested in making a sale then helping out
