If you ever make it over to this part of the country, drop into a "Braum's" store, and get a half-gallon of skim milk. They've never used BHG growth hormone, and vacuum-process their skim milk to concentrate it. If you compare it to other brands, the other brands are so thin, they're a pale blue, while the stuff from Braum's is bright white.
Of course, I used to work for that company for 6 years.
It also helps that a gallon of 2% milk from them is $2.79/gallon, while the cheapest stuff from Wally-World is $3.50/gallon.
