any supplement that has 'dietary supplement' has never been tested for anything by the fda. so basically it depends on if we believe the company or not. for all we know it can be cookie dough. go on the internet and do searches for dietary supplement and you will see what i am talking about. i still use protein powders, but never as meals. usually in between meals or with a meal. the ones i like are designer protein and pro complex. never had any bad experiences with each.
