Recombinant bovine somatotropin (usually "rBST"), is a synthetic version of the bovine growth hormone given to dairy cattle by injection to increase milk production. Controversy over its safety has led to it being banned in several countries, including the European Union since 1990, and Canada, Japan, Pakistan, Australia, New Zealand, and ...
Recombinant bovine growth hormone (rBGH), also known as recombinant bovine somatotropin (rBST), is used by some dairy farmers to increase milk production in cattle (cows). It was first approved for use in the United States by the Food and Drug Administration (FDA) in 1993, but its use is not permitted in the European Union, Canada, and some ...

Some of the approved drugs are naturally produced throughout life in people and animals, such as estradiol (estrogen), progesterone, and testosterone. These natural hormones are necessary for normal development, growth, and reproduction. People are not at risk from eating food from animals treated with these drugs because the amount of additional h...
Some of the approved drugs are synthetic versions of the natural hormones, such as trenbolone acetate and zeranol. Just like the natural hormone implants, before FDA approved these drugs, FDA required information and/or toxicological testing in laboratory animals to determine safe levels in the animal products that we eat (edible tissues). Furtherm...
Information about approved hormonal implant products can be found in the Code of Federal Regulations (CFR), Title 21, Parts 522 and 556. Paper copies of the CFR may be found at your local public or university library and are for sale from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402.

Recent research has also shown that the levels of a hormone called “insulin-like growth factor-1″ (IFG-1) are elevated in dairy products produced from cows treated with rbGH. Canadian and European regulators have found that the FDA completely failed to consider a study that showed how the increased IGF-1 in rBGH milk could survive digestion ...
Jan 20, 2022 · Growth hormone binds to spotlight tissues cell receptors, which drives the direct action of the hormone. The indirect action is commanded by Insulin-like growth factor I (IGF-I) production, preceded by growth hormone fixation on liver cells receptor.
