Whey from hormone-free cows

[Singleton]

I am looking for whey protein from cows not treated with hormones such as rBGH.

I want whey isolate or a blend of isolate and partially hydrolysed concentrate.

This is the best deal I could find:

Optimum is much cheaper, but comes with cows that were pumped full of hormones.
