Like most people, ill suggest Optimum Whey

Damn man, you got some standards.

Ever been to Trueprotein.com? They might be a good help to you.

I using Scivation Whey strawberry flavor for nearly 2years & it really effects good in my muscle. I used to buy 5LB, actually Scivation Whey is loaded with BCAA's and Glutamine to help build lean muscle & is fast acting, ideal for pre and post workouts.

I alternate between Dymatize whey and Vitamin World's Precision Engineered Whey. I always get the 5 pounders.

Good Question
 

I did find this protein powder for you, Optimum Nutrition 100% Why Natural. I haven't tried it yet, but I just might!

Oh it has a bunch of requirements you listed, I don't know about the grass fed thing though. I wonder if Whole Foods has something like that?

Optimum Nutrition Whey is a favorite... Rocky Road!

Im sure something like this exists but it will not we widely marketed.
Closest ones are

Being cold pressed generally applies to products that are high in good fats such as flax oil , ect..

Why would you want all or mainly from concentrates unless you are looking for hydrolized whey (enzymatically broken down concentrate) Concentrates take longer to digestslightly and have more fats and free radicals. Its the same protein as isolate just with more crap left in it.
J Robb is wbgh free I believe, but especially if eating pure protein this is irrelevant because you are taking pure proteins/linked aminos. If taking as concentrates this would be more relevant due to the increased "crap" that is in there (fats ect..)

naturally sweetend supplements are definetly the way to go as most people dont realize the effects of the splenda (sucralose) that the are taking all of the time.

My brand of choice is Healthy 'N Fit price & quality. Available at Fit-RX and Vitamin Shoppe and most big retailers.

There is alot more about proteins than most people think about. I will try to make it on here more oftern for a resource.

Is there any specific reason why you're looking for such proteins? Health conditions? Or is it just an exercise of looking for more advanced/purer and possibly healthier proteins?

I really this post about the protein powder. I have been looking all over for this! Thanks a lot.
