By the way, I ordered ION Whey Isolate (4 lbs) from PF and it arrived in a plastic bag. Save some old empty containers to put it in when it arrives in the mail.
Sorry about the earlier post. The whey is faster absorbing and the caseinate is slow digesting. I have had great success with ordering from The Protein Factory.
Go to the articles section, and look up the formula for the "psycho bodybuilder". Buy this formula, and add an equal amount of carbs, use it post workout only. My friend and I both did and noticed a difference in recovery. The formula consists of hydrolyzed whey, hydrolyzed casein, CFM whey, glutamine peptides and glutamine. I added dextrose and maltodextrin along with aminogen. I use this for postworkout with a teaspoon of creatine. Never felt better the next day. Oh, it tastes really bad
