Hi, whey protein is just dried milk without the calcium caseinate, lactose, and fat... plain and simple. It's best to use whey protein only for pre-and-post workout nutrition. You're really better off getting the rest of your protein from real food. Drink it 30-45 minutes before working out. For post-workout nutrition it gets a little trickier because the mixture depends on your goals. The post-workout shake is made from skim milk, whey protein. Use one cup of skim milk and a full scoop of whey protein. I hope this helps.
different supplements have different types of use.... It is usually wriiten on the back of it .. But if it isn't any instructions then usually we take one scoop with a cup of water or milk .. You can also take this twice a day if u want serious mass..!! good luck ( feel free to ask any question ... m paki as well ) :)
