Before I purchase any protein powders, I was narrowing it down to Dymatize ISO-100, Kaizen Whey Isolate, Trutein IsoWhey do I have to have hydrolysate, casein, whey to be successful and reach my goals?I want to, from a financial standpoint buy one kind and like mentioned thinking of either of the three above.How would this affect my goals(fat loss, get fit) if any?If I'm going to add 10g into my shakes at times like he talks about in the books would either of these be okay to do that with?Thanks
