When i lived in the US I got my protein powders at http://www.trueprotein.com
. Buy a years supply and save yourself some cash.
Myself I don't really use soy protein powder as i have enough soy anyway in my diet! Have a look at hemp, brown rice, pea powders.
And yeah i blend with fruit, cocoa and other stuff to make it all nice
ice and soy yogurt (see it turns up everywhere!) make it nice too!
JS - They think it will open the door to folk like LordMuppet campaigning for a threeway?
