I want a protien isolate with nothing else in it, i have some isopure but now ive seen this site called protien factory.com were you make your own.. Even if it will cost extra, is it wise to get the ion exchange isolate on its own with nothing else in it?? Well only splenda and choc flav.. And what about Hydrolyzed whey,could i get that seperate also? Is that a good idea or not? Any kind of help would be appreciated...
