How do growth hormones in animals affect humans?
Recombinant bovine growth hormone (rBGH), which is a synthetic cow hormone that encourages milk production, has no detectable effect on humans. However, manipulating growth hormones in this way may actually increase the production of other hormones such as insulin-like growth factor-1 (IGF-1).
