how much do isopure's selling? they use ion exchange whey,
protein factory sells at $8.79 per pound, other's claim using CFM and hydrolyzed whey,hydrolyzed whey smells like dead fish and taste very bitter,if not for the increased in US$ xchang rate I would still buy from them, their hydrolyzed whey dalton 520,kick ass big time and don' believe that caseinate is better, these form of protein is cheap and higher profit margin for bottlers, and these company do not processed their own products, that's why I called them bottlers.
