some of the products tested did not meet label claims tested by a 3rd party test lab, it's something that happens. I worked in a independant test lab for 5 years, I know first hand that it does happen from quality manufactures of high-end products.
I've been using the PF for over 6 years. I have no complaints about them. My favorite is a a custom blended protein mixture that utilizes 40% caesin, 20% egg white protein and 20% whey protein isolates. Mixed with Aminogen and the fruit punch flavoring you have a dam good tasting blended protein.
