This is really a product question more than a general nutrition question.
Currently I like buying Isopure Unflavored. Aside from the lack of 3rd party testing, it is a great whey isolate. And it has been subjected to “a” 3rd party testing at least once - that is by Garage Gym Reviews who like everything about Isopure except the lack of 3rd party testing.
So, if you guys ever offer an unflavored version of Whey Rx, I would certainly try it out as a way of supporting BBM - I mean I think the world needs you guys to be successful and I’m willing to do my part. To be fair, I don’t know how many people besides me are really excited about unflavored whey isolate…
