The growth hormones in milk are protein hormones (unlike the sex hormones or thyroid hormone). They are destroyed in the stomach when they are ingested so they have no effect in humans who drink milk. That is the reason why insulin (also a protein hormone) must be injected and not taken by mouth.
Thank you for the information. If one doesn't have technical knowledge on an issue like this one, it is hard to know who is credible and who isn't.
