It is a common fact that Starbucks serves up caffeine.
But did you know the restaurant chain can also give you a dose of a growth hormone?
Starbucks is moving to get a growth hormone called RGBH out of its dairy products.
Dairy farmers use the hormone to increase milk production.
But, critics say it could lead to cancer in cattle and humans.
Starbucks has already boosted its hormone-free percentage up to 37%.
That is up ten points from last year.
